Method for Treating Proliferative Diseases

This invention describes novel methods of treating subjects afflicted with proliferative diseases such as cancers, tumors, or metastatic disease. In particular, this invention provides methods of inhibiting the proliferation of cells, more specifically cancer cells, comprising the combined use of (1) a farnesyl protein transferase ("FPT") inhibitor and (2) an antineoplastic agent and/or radiation therapy.

Oncogenes frequently encode protein components of signal transduction pathways which lead to stimulation of cell growth and mitogenesis. Mutation and/or overexpression of certain oncogenes is frequently associated with cellular tranformation and human cancer. To acquire transforming potential, the precursor of the ras oncoprotein must undergo farnesylation of the cysteine residue located in a carboxyl-terminal tetrapeptide. Inhibitors of the enzyme that catalyzes this modification, farnesyl protein transferase, have therefore been suggested as anticancer agents for tumors. Mutated, oncogenic forms of ras are frequently found in many human cancers, most notably in more than 50% of colon and pancreatic carcinomas (Kohl et al., Science, Vol. 260, 1934 to 1937, (1993)). Proteins other than ras may play a part in tumorigenicity and may also require farnesylation for biological activity.

International Patent Publication Number WO92/11034 (published Jul. 9, 1992) discloses a method of increasing the sensitivity of a tumor to an antineoplastic agent (in cases where the tumor is resistant to the antineoplastic agent), by the concurrent administration of the antineoplastic agent and (inter alia) a potentiating agent of the formula: ##STR1## wherein the dotted line represents an optional double bond, X' is hydrogen or halo, and Y' is hydrogen, substituted carboxylate or substituted sulfonyl. For example, Y' can be, amongst others, --COOR' wherein R' is C-1 to C-6 alkyl or substituted ally, phenyl, substituted phenyl, C-7 to C-12 aralkyl or substituted aralkyl, 2-, 3- or 4-piperidyl or N-substituted piperidyl. Y' can also be, amongst others, SO.sub.2 R' wherein R' is C-1 to C-6 alkyl, phenyl, substituted phenyl, C-7 to C-12 aralkyl or substituted aralkyl. Examples of such potentiating agents include 11-(4-piperidylidene)-5H-benzo[5,6]cyclohepta[1,2-b]pyridines such as Loratadine. Antineoplastic agents exemplified are: vinca alkaloids, epipodophyllotoxins, anthracycline antibiotics, actinomycin D, plicamycin, puromycin, gramicidin D, taxol, colchicine, cytochalasin B, emetine, maytansine, and amsacrine. The WO92/11034 publication focuses on potentiating the antineoplastic agents through a specific mechanism of action: inhibition of multiple drug resistance.

In view of the need for improved treatments for proliferative diseases, particularly cancers, novel methods of treatment would be a welcome contribution to the art. The present invention provides just such methods of treatment.

The present invention provides methods of treating proliferative disease in a patient (e.g., a mammal such as a human) in need of such treatment, said treatment comprising administering, concurrently or sequentially, an effective amount of (1) a farnesyl protein transferase (FPT) inhibitor, and (2) an antineoplastic agent and/or radiation therapy. The methods of the present invention are particularly useful for the treatment of various cancers, especially epithelial cancers, e.g., prostate cancer, lung cancer, breast cancer, colorectal cancer, and pancreatic cancer. In preferred embodiments, the FPT inhibitor is combined with one of the following antineoplastic agents: gemcitabine, paclitaxel (Taxol.RTM.), 5-Fluorouracil (5-FU), cyclophosphamide (Cytoxan.RTM.), temozolomide, or Vincristine.

For instance, in a preferred embodiment, the present invention provides a method of treating cancer, comprising administering, concurrently or sequentially, an effective amount of (1) a farnesyl protein transferase (FPT) inhibitor, and (2) gemcitabine. In a particularly preferred embodiment, the cancer to be treated is a pancreatic cancer.

In another preferred embodiment, the present invention provides a method of treating cancer, comprising administering, concurrently or sequentially, an effective amount of (1) a farnesyl protein transferase (FPT) inhibitor, and (2) a microtubule affecting agent (e.g., paclitaxel).

In view of International Patent Publication WO92/11034, the present specification includes provision of a method of treating proliferative disease, said treatment comprising administering, concurrently or sequentially, an effective amount of (1) an FPT inhibitor, and (2) an antineoplastic agent and/or radiation therapy; with the proviso that when the FPT inhibitor is a compound of the formula: ##STR2## wherein:

the dotted line represents an optional double bond;

X' is hydrogen or halo; and

Y' is hydrogen, --COOR' wherein R' is C.sub.1 to C.sub.12 alkyl or substituted alkyl, phenyl, substituted phenyl, C.sub.7 to C.sub.12 arylalkyl or substituted arylalkyl, 2-, 3- or 4-piperidyl or N-substituted piperidyl, wherein the substituents on said substituted C.sub.1 to C.sub.12 alkyl are selected from amino and substituted amino, and the substituents on the substituted amino are selected from C.sub.1 to C.sub.6 alkyl, the substituents on said substituted phenyl and on said substituted aryl moiety of the C.sub.7 to C.sub.12 arylalkyl are selected from C.sub.1 to C.sub.6 alkyl and halo, and the substituent on said N-substituted piperidyl is C.sub.1 to C.sub.4 alkyl, or --SO.sub.2 R' wherein R' is C.sub.1 to C.sub.12 alkyl, phenyl, substituted phenyl, C.sub.7 to C.sub.12 arylalkyl or substituted arylalkyl, wherein the substituents on said substituted phenyl and on said substituted aryl moiety of the C.sub.7 to C.sub.12 arylalkyl are selected from C.sub.1 to C.sub.6 alkyl and halo;

then the antineoplastic agent is not selected from vinca alkaloids, epipodophyllotoxins, anthracycline antibiotics, actinomycin D, plicamycin, puromycin, gramicidin D, taxol, colchicine, cytochalasin B, emetine, maytansine, or amsacrine.

FIG. 36 graphically represents the data provided in Table 2, which is set forth later on in the present specification. The Y-axis (vertical axis, numbers 0-1500) represents the tumor volume, in cubic millimeters (mm.sup.3), on day 25. The X-axis (horizontal axis, numbers 1-8) represents the substances administered. Numbers 1-8 represent: 1 is the vehicle; 2 is the FPT Inhibitory Compound (identified as "Compound X" in Table 2); 3 is Cytoxan; 4 is 5-FU; 5 is Vincristine; 6 is the FPT Inhibitory Compound plus Cytoxan; 7 is the FPT Inhibitory Compound plus 5-FU; and 8 is the FPT Inhibitory Compound plus Vincristine. FIG. 36 represents experiments wherein HTB177 cells were implanted subcutaneously in nude mice on day 0. The FPT Inhibitory Compound, dosed orally at 40 mpk, four times a day on days 1-26, resulted in 68% tumor growth inhibition. Chemo-therapeutic agents were administered intraperitoneally on day 13. When used as single agents the cytotoxics yielded 9%, 28% and 7% inhibition for Cytoxan (Cyclophosphamide) (200 mpk), 5-Fluorouracil (5-FU) (50 mpk), and Vincristine (1 mpk), respectively. When the FPT Inhibitory Compound X (40 mpk) was used in combination with the cytotoxics, tumor growth inhibition of 81%, 80% and 80% was observed for the combination with Cytoxan, 5-FU and Vincristine, respectively. These results indicate that enhanced efficacy is observed when the FPT Compound is combined with the cytotoxic chemotherapeutic agents compared to treatment with single agents. Similar results were observed when the FPT compound was dosed using a twice a day schedule. The data in FIG. 36 represented by bars 6, 7 and 8 had a P value <0.05 compared to each single agent treatment.

FIG. 37 graphically represents tumor regression data. The Y-axis (vertical axis, numbers 0-2000) represents the tumor volume in cubic millimeters (mm.sup.3). The X-axis (horizontal axis, numbers 1-7) represents the substances administered. Numbers 1-7 represent: 1 is 20% HPBCD (vehicle); 2 is the FPT Inhibitory Compound X dosed at 2.5 mpk; 3 is the FPT Inhibitory Compound X dosed at 10 mpk; 4 is the FPT Inhibitory Compound X dosed at 20 mpk; 5 is the FPT Inhibitory Compound X dosed at 30 mpk; 6 is the FPT Inhibitory Compound X dosed at 10 mpk and Cytoxan dosed at 200 mpk; and 7 is Cytoxan dosed at 200 mpk. The number of days (0, 7, 14, 21 or 28) represented by a particular bar in the graph is indicate done of the patterns set forth in the legend in the upper right portion of FIG. 37. The data in FIG. 37 was obtained from the evaluation of the FPT Inhibitory compound in a transgenic mouse model in which an activated H-Ras oncogene is expressed from whey acidic promoter (Nielsen et al., Evaluation of the wap-ras Transgenic Mouse as a Model System for Testing Anticancer Drugs, Cancer Research 52, 3733-3738, Jul. 1, 1992). Since the transgene is carried on the Y chromosome, male transgenics reproducibly develop tumors (breast and salivary gland) at about 1.5 to 2 months of age. This model has been run in a therapeutic mode in which treatment was initiated after mice had developed palpable tumors (mean tumor size at the start of dosing was 200 mm.sup.3). Mice were dosed orally four times a day with 2.5, 10, 20 or 30 mpk of the FPT Inhibitory Compound for 4 weeks. Some mice were also treated by weekly intraperitoneal injection with Cytoxan (Cyclophosphamide) at 200 mpk. Growth curves for the various treatment groups are shown in the bar graph in FIG. 37. In the vehicle-treated control group, tumors grew throughout the course of the experiment to a volume of >1500 mm.sup.3 by the end of the study. Cytoxan alone resulted in near complete inhibition of tumor growth but no significant tumor regression. The FPT Inhibitory Compound at the 20 and 30 mpk dose levels resulted in significant tumor regression. The FPT Inhibitory Compound at 2.5 or 10 mpk slowed the rate of tumor growth but did not result in tumor regression. Surprisingly, while Cytoxan or 10 mpk of the FPT Inhibitory Compound as single agents did not result in tumor regressions, the combination of these treatments resulted in significant tumor regression. This indicates that, when used in combination with a standard chemotherapeutic agent such as Cytoxan, greater tumor responses can be obtained at lower doses of the FPT Inhibitory Compound.

FIG. 38 shows data for combination therapy (in the Wap-ras transgenic model) with Compound X and paclitaxel relative to mean tumor volume (expressed in mm.sup.3 along the y-axis) over time. The curve with white boxes represents paclitaxel alone (5 mpk), the white circles represent Compound X alone (20 mpk), the cross-hatched boxes represent the combination of paclitaxel (5 mpk) plus Compound X (20 mpk), and the black boxes represent vehicle without drug.

The present invention provides a method of treating proliferative diseases, especially cancers, by combining (1) a method for inhibiting FPT (using the FPT inhibitors described herein) with (2) a method for treating cancer (using a chemotherapeutic agent and/or radiation).

The FPT inhibitors are compounds which: (i) potently inhibit FPT (but preferably not geranylgeranyl protein transferase I, in vitro); (ii) block the phenotypic change induced by a form of transforming H-ras which is a farnesyl acceptor (but preferably not by a form of transforming H-ras engineered to be a geranyl--geranyl acceptor); (iii) block intracellular farnesylation of ras; and (iv) block abnormal cell growth.

The method of treating proliferative diseases, according to this invention, includes a method for treating (inhibiting) the abnormal growth of cells, including transformed cells, in a patient in need of such treatment (e.g., a mammal such as a human), by administering, concurrently or sequentially, an effective amount of an FPT inhibitor and an effective amount of a chemotherapeutic agent and/or radiation. Abnormal growth of cells means cell growth independent of normal regulatory mechanisms (e.g., loss of contact inhibition), including the abnormal growth of: (1) tumor cells (tumors) expressing an activated ras oncogene; (2) tumor cells in which the ras protein is activated as a result of oncogenic mutation in another gene; and (3) benign and malignant cells of other proliferative diseases.

In preferred embodiments, the methods of the present invention include methods for treating or inhibiting tumor growth in a patient in need of such treatment (e.g., a mammal such as a human) by administering, concurrently or sequentially, (1) an effective amount of an FPT inhibitor and (2) an effective amount of an antineoplastic agent and/or radiation therapy. Examples of tumors which may be treated include, but are not limited to, epithelial cancers, e.g., prostate cancer, lung cancer (e.g., lung adenocarcinoma), pancreatic cancers (e.g., pancreatic carcinoma such as, for example, exocrine pancreatic carcinoma), breast cancers, colon cancers (e.g., colorectal carcinomas, such as, for example, colon adenocarcinoma and colon adenoma), ovarian cancer, and bladder carcinoma. Other cancers that can be treated include melanoma, myeloid leukemias (for example, acute myelogenous leukemia), sarcomas, thyroid follicular cancer, and myelodysplastic syndrome.

The methods of treating proliferative diseases, according to this invention, also include a method for treating (inhibiting) proliferative diseases, both benign and malignant, wherein ras proteins are aberrantly activated as a result of oncogenic mutation in other genes--i.e., the ras gene itself is not activated by mutation to an oncogenic form. This method comprises administering, concurrently or sequentially, an effective amount of an FPT inhibitor and an effective amount of an antineoplastic agent (and/or radiation therapy) to a patient in need of such treatment (e.g., a mammal such as a human). Examples of such proliferative diseases which may be treated include: the benign proliferative disorder neurofibromatosis, or tumors in which ras is activated due to mutation or overexpression of tyrosine kinase oncogenes (e.g., neu, src, abl, lck, lyn, fyn).

As used herein the following terms have the following meanings unless indicated otherwise:

antineoplastic agent--a chemotherapeutic agent effective against cancer;

concurrently--(1) simultaneously in time, or (2) at different times during the course of a common treatment schedule; and

sequentially--(1) administration of one component of the method ((a) FPT inhibitor, or (b) antineoplastic agent and/or radiation therapy) followed by administration of the other component; after adminsitration of one component, the second component can be administered substantially immediately after the first component, or the second component can be administered after an effective time period after the first component; the effective time period is the amount of time given for realization of maximum benefit from the administration of the first component.

Methods for the safe and effective administration of most of these chemotherapeutic agents are known to those skilled in the art. In addition, their administration is described in the standard literature. For example, the administration of many of the chemotherapeutic agents is described in the "Physicians' Desk Reference" (PDR), e.g., 1996 edition (Medical Economics Company, Montvale, N.J. 07645-1742, USA); the disclosure of which is incorporated herein by reference thereto.

As explained above, the present invention also provides methods of treating diseased cells by contacting the cells with a FPT inhibitor and a microtubule affecting agent (e.g., paclitaxel, a paclitaxel derivative or a paclitaxel-like compound). As used herein, a microtubule affecting agent is a compound that interferes with cellular mitosis, i.e., having an anti-mitotic effect, by affecting microtubule formation and/or action. Such agents can be, for instance, microtubule stabilizing agents or agents which disrupt microtubule formation.

Microtubule affecting agents useful in the invention are well known to those of skill in the art and include, but are not limited to allocolchicine (NSC 406042), Halichondrin B (NSC 609395), colchicine (NSC 757), colchicine derivatives (e.g., NSC 33410), dolastatin 10 (NSC 376128), maytansine (NSC 153858), rhizoxin (NSC 332598), paclitaxel (Taxol.RTM., NSC 125973), Taxol.RTM. derivatives (e.g., derivatives (e.g., NSC 608832), thiocolchicine (NSC 361792), trityl cysteine (NSC 83265), vinblastine sulfate (NSC 49842), vincristine sulfate (NSC 67574), epothilone A, epothilone, and discodermolide (see Service, (1996) Science, 274:2009) estramustine, nocodazole, MAP4, and the like. Examples of such agents are also described in the scientific and patent literature, see, e.g., Bulinski (1997) J. Cell Sci. 110:3055-3064; Panda (1997) Proc. Natl. Acad. Sci. USA 94:10560-10564; Muhlradt (1997) Cancer Res. 57:3344-3346; Nicolaou (1997) Nature 387:268-272; Vasquez (1997) Mol. Biol. Cell 8:973-985; Panda (1996) J. Biol. Chem. 271:29807-29812.

Particularly preferred agents are compounds with paclitaxel-like activity. These include, but are not limited to paclitaxel and paclitaxel derivatives (paclitaxel-like compounds) and analogues. Paclitaxel and its derivatives are available commercially. In addition, methods of making paclitaxel and paclitaxel derivatives and analogues are well known to those of skill in the art (see, e.g., U.S. Pat. Nos. 5,569,729; 5,565,478; 5,530,020; 5,527,924; 5,508,447; 5,489,589; 5,488,116; 5,484,809; 5,478,854; 5,478,736; 5,475,120; 5,468,769; 5,461,169; 5,440,057; 5,422,364; 5,411,984; 5,405,972; and 5,296,506).

More specifically, the term "paclitaxel" as used herein refers to the drug commercially available as Taxol.RTM. (NSC number: 125973). Taxol.RTM. inhibits eukaryotic cell replication by enhancing polymerization of tubulin moieties into stabilized microtubule bundles that are unable to reorganize into the proper structures for mitosis. Of the many available chemotherapeutic drugs, paclitaxel has generated interest because of its efficacy in clinical trials against drug-refractory tumors, including ovarian and mammary gland tumors (Hawkins (1992) Oncology, 6: 17-23, Horwitz (1992) Trends Pharmacol. Sci. 13: 134-146, Rowinsky (1990) J. Natl. Canc. Inst. 82: 1247-1259).

Additional microtubule affecting agents can be assessed using one of many such assays known in the art, e.g., a semiautomated assay which measures the tubulin-polymerizing activity of paclitaxel analogs in combination with a cellular assay to measure the potential of these compounds to block cells in mitosis (see Lopes (1997) Cancer Chemother. Pharmacol. 41:37-47).

Generally, activity of a test compound is determined by contacting a cell with that compound and determining whether or not the cell cycle is disrupted, in particular, through the inhibition of a mitotic event. Such inhibition may be mediated by disruption of the mitotic apparatus, e.g., disruption of normal spindle formation. Cells in which mitosis is interrupted may be characterized by altered morphology (e.g., microtubule compaction, increased chromosome number, etc.).

In a preferred embodiment, compounds with possible tubulin polymerization activity are screened in vitro. In a preferred embodiment, the compounds are screened against cultured WR21 cells (derived from line 69-2 wap-ras mice) for inhibition of proliferation and/or for altered cellular morphology, in particular for microtubule compaction. In vivo screening of positive-testing compounds can then be performed using nude mice bearing the WR21 tumor cells. Detailed protocols for this screening method are described by Porter (1995) Lab.

Other methods of screening compounds for desired activity are well known to those of skill in the art. Typically such assays involve assays for inhibition of microtubule assembly and/or disassembly. Assays for microtubule assembly are described, for example, by Gaskin et al. (1974) J. Molec. Biol., 89: 737-758. U.S. Pat. No. 5,569,720 also provides in vitro and in vivo assays for compounds with paclitaxel-like activity.

Methods for the safe and effective administration of the above-mentioned microtubule affecting agents are known to those skilled in the art. In addition, their administration is described in the standard literature. For example, the administration of many of the chemotherapeutic agents is described in the "Physicians' Desk Reference" (PDR), e.g., 1996 edition (Medical Economics Company, Montvale, N.J. 07645-1742, USA); the disclosure of which is incorporated herein by reference thereto.

Classes of compounds that can be used as the FPT inhibitor include: oligopeptides, peptido-mimetic compounds, farnesylated peptido-mimetic compounds, fused-ringed tricyclic benzocycloheptapyridines, carbonyl piperazinyl compounds, carbonyl piperidinyl compounds, farnesyl derivatives, and natural products and derivatives.

Some of the compounds are oligopeptides, especially tetrapeptides, or derivatives thereof, based on the formula Cys-Xaa.sub.1 -Xaa.sub.2 -Xaa.sub.3, where Xaa.sub.3 represents a serine, methionine or glutamine residue, and Xaa.sub.1 and Xaa.sub.2 can represent a wide variety of amino acid residues, but especially those with an aliphatic side-chain. Their derivatives may or may not have three peptide bonds; thus it has been found that reduction of a peptide bond --CO--NH-- to a secondary amine grouping, or even replacement of the nitrogen atoms in the peptide chain with carbon atoms (provided that certain factors such as general shape of the molecule and separation of the ends are largely conserved) affords compounds that are frequently more stable than the oligopeptides and, if active, have longer activity. Such compounds are referred to herein as peptido-mimetic compounds.

Examples of compounds that are FPT inhibitors and the documents directed to those compounds are given below.

A plasmid encoding an .alpha.- and .beta.-unit of an FPT, and describing an assay therefor: WO 94/10184.

All of the foregoing documents directed to compounds that are FPT inhibitors are incorporated herein by reference thereto.

A review of many such compounds is given by Graham in Exp. Opin. Ther. Patents (1995) 5(12): 1269-1285.

It will be understood that the breadth of a chemical formula in a patent specification may not enable one to classify all compounds therein under one of the headings above. For example, the monoterpenyl chain in the farnesyl derivatives may be extended, e.g. by a number of methylene groups or even another isoprene residue.

The tetrapeptides of the formula Cys-Xaa.sub.1 -Xaa.sub.2 -Xaa.sub.3 have an amino-terminal cysteine residue. A tetrapeptide of that type forms the carboxyl-terminal of ras. Such tetrapeptides are capable of binding with FPT and competing with ras. Compounds of similar structure but having at least one of the carbonyl groups of the tetrapeptide replaced by a hydrocarbyl group such as a methylene group and classified above as peptido-mimetic compounds are also capable of binding with FPT and competing with ras, but are generally more resistant to enzymatic degradation in vivo.

The following documents disclose compounds that are FPT inhibitors that can be used in this invention. The documents also disclose methods of inhibiting abnormal cell growth (e.g., tumors) using the compounds disclosed in the document. The radicals and formulae designations defined herein for a particular document apply only to the compounds described in that document.

Studies of Compound X and Paclitaxel in p53.sup.mut MDA-MB-468 Breast Cancer Cells

In the following three Examples (E through G), the effects of Compound X and paclitaxel were studied in p53.sup.mut MDA-MB-468 breast cancer cells. In two of the examples (Examples F and G), Compound X and paclitaxel had synergistic interaction, but in Example E the interaction was found to be antagonistic. The cells in Examples F and G appear to have had a better proliferative rate than the cells in Example E, which may have influenced the outcome, although the Isobole curves are atypical in all three of these studies with p53.sup.mut MDA-MB-468 breast cancer cells.

Data based on combining a particular peptido-mimetic FTI compound with several different chemotherapeutic agents (e.g., taxol (paclitaxel), doxorubicin, cisplatin, and vinblastine) in breast cancer cell lines MDA-MB-468 and MCF-7 are presented in Moasser, MM, et aL. Proc. Natl. Acad. Sci. USA 95: 1369-1374, 1998. Results of additional experiments combining the FTI compound with taxol were reported in the Moasser publication (data not shown) for T47D, MDA-MB-231, and MCF-7 breast cancer cells, and for DU-145 prostate cancer cells. Additional results were reported in the publication (data not shown) for fluorouracil in breast cancer cells.

The data was analyzed using the Thin Plate Spline methodology of O'Connell and Wolfinger (1997).

Results: Compound X and paclitaxel had antagonistic interaction (p=0.0001). FIG. 21 shows the Isobole analysis for the interaction of these drugs while FIG. 22 shows the 3-dimensional model of cell proliferation from which FIG. 21 was derived. FIGS. 23, 24, and 25 show the dose response curves before statistical analysis.

Compound X and Paclitaxel Have a Synergistic Interaction in p53.sup.mut MDA-MB-468 Breast Cancer Cells (Study #2)

Methods: p53.sup.mut MDA-MB-468 tumor cells were aliquoted into culture wells and allowed to attach for 3 hrs. The cells were incubated with paclitaxel for 4 hrs., washed, then Compound X was added and the incubation continued for 7 days. Cell proliferation was quantified using the MTT assay of Mosmann. The data was analyzed using the Thin Plate Spline methodology of O'Connell and Wolfinger (1997).

Results: Compound X and paclitaxel had a synergistic interaction (p=0.0237). FIG. 26 shows the Isobole analysis for the interaction of these drugs, while FIG. 27 shows the 3-dimensional model of all proliferation from which FIG. 26 was derived. FIGS. 28, 29, and 30 show the dose response curves before statistical analysis. The cells in this study had a better proliferative rate than the cells in the previous study (Example E), which may have influenced the outcome, although the Isobole curves are atypical in both studies.

Methods: p53.sup.mut MDA-MB-468 tumor cells were aliquoted into culture wells and allowed to attach for 3 hrs. The cells were incubated with paclitaxel for 4 hrs., washed, then Compound X was added and the incubation continued for 7 days. Cell proliferation was quantified using the MTT assay of Mosmann. The data was analyzed using the Thin Plate Spline methodology of O'Connell and Wolfinger (1997).

Results: Compound X and paclitaxel had a synergistic interaction (p=0.0094). FIG. 31 shows the Isobole analysis for the interaction of these drugs, while FIG. 32 shows the 3-dimensional model of all proliferation from which FIG. 31 was derived. FIGS. 33, 34, and 35 show the dose response curves before statistical analysis. As was the case with Example F, the cells in Example G appear to have had a better proliferative rate than the cells in Example E, which may have influenced the outcome, although the Isobole curves are atypical in all these studies with p53.sup.mut MDA-MB-468 breast cancer cells.

IN VIVO COMBINATION THERAPY--B.I.D.

The effect of in vivo combination therapy of an FPT inhibitory compound (referred to as "Compound X" in the Tables below) ##STR171## with paclitaxel on HTB 177 xenografts (NCI-H460, a human lung large cell carcinoma) using two times a day dosing was determined.

Athymic nu/nu female mice, 5-6 weeks old were used. On Day 0, HTB 177 cells, 3.times.10.sup.6, were injected s.c. into the flank of 120 mice. An overview of the groups is set forth below:

Formulation: Compound X for groups 3, 4, 7, 8, 9, and 10 was dissolved in 20% hydroxyl-propyl-betacyclodexatrin (Vehicle I). 0.2 ml of Compound X solution was the dosing volume. Paclitaxel was dissolved in a diluted ethanol/cremophor EL solution (Vehicle II) and the i.p. dosing volume for paclitaxel was 0.1 ml.

The 80 mpk dosing solution of Compound X was made by adding 17 ml of 20% HPBCD to a 50 ml tube containing 136 mg of Compound X to dissolve the compound. The mixture was sonicated until a complete solution was made.

The 20 mpk dosing solution was made by placing 2 ml of the 80 mpk solution into a 15 ml tube, adding 6 ml of 20% HPBCD, and vortexing the solution to mix it.

Protocol: Tumor cells were inoculated into 120 mice in the morning of Day 0, and the mice are weighed, randomized, and ear-marked afterwards. Drug treatment began at 7:30 am on Day 4. The animals in groups 2, 3, 4, 7, 8, 9, 10, and 11 were dosed p.o., B.I.D. with Compound X or vehicle I solution (HPBCD), at 7:30 am, and 7:30 pm, 7 days a week. Groups 5, 6, 7, 8, 9, 10 and 11 are dosed i.p., on Day 4 to Day 7, with paclitaxel or vehicle II solution. Tumor growth is quantitated by measuring tumor volume on Day 7 and Day 14.

The results are given in Table 1 below:

With regard to Table 1 above, it is particularly noteworthy that while Compound X alone at 20 mpk exhibited only 52% average inhibition (Experiment 4) and paclitaxel alone at 5 mpk exhibited only 61% average inhibition (Experiment 6), the combination of Compound X at 20 mpk plus paclitaxel at 5 mpk resulted in 86% average inhibition (see Experiment 10).

IN VIVO COMBINATION THERAPY--Q.I.D.

The effect of in vivo combination therapy of an FPT inhibitory compound (referred to as "Compound X" in Table 2 below) ##STR172## with chemotherapeutic agents on HTB 177 (NCI-H460, a human lung large cell carcinoma) using four times a day dosing was determined.

Athymic nu/nu female mice, 5-6 weeks old were used. On Day 0, HTB 177, 3.times.10.sup.6, was injected s.c. into the flank of 170 mice. Afterwards the mice were weighed and randomly divided into 17 groups of 10 mice per group. Drug treatment began at about 6:00 am on Day 1. The mice in groups 2, 3, 4, 5, 9, 10, 11, 12, 13, 14, 15, 16, and 17 were dosed p.o., q.i.d., at about 6 am, 12 noon, 6 pm, and 12 midnight, 7 days a week for 4 weeks. The mice in Groups 6-17 were dosed i.p. once with the indicated cytotoxic agent (see Table 1) on Day 13. The primary tumors were measured two times a week. The results are given in Table 2.

The Compound X (FPT Inhibitory Compound) for Groups 3, 4, 5, 9, 10, 11, 12, 13, 14, 15, 16, and 17 was dissolved in 20% hydroxypropylbetacyclodextran (HPBCD). Cytoxan, 5-FU, and Vincristine were dissolved in sterile water.

The 40 mpk dosing solution of Compound X was made by adding 39.6 ml of 20% HPBCD to a 50 ml tube containing 320 mg of Compound X to dissolve the compound. The mixture was sonicated until a complete solution was made. Aliquots of the solution were prepared ahead of time for the needed number of doses for the following 24 hour period. Aliquots of the 20% HPBCD were period ahead of time for the needed number of dosings with Vehicle Control on the specific day of dosing.

The 20 mpk dosing solution was made by placing 2 ml of the 80 mpk solution into a 15 ml tube, adding 6 ml of 40% HPBCD, and vortexing the solution to mix it.

IN VIVO COMBINATION THERAPY--B.I.D.

The effect of in vivo combination therapy of an FPT inhibitory compound (referred to as "Compound X" in Table 3 below) ##STR173## with the chemotherapeutic agent Cytoxan on HTB 177 (NCI-H460, a human lung large cell carcinoma) using twice a day dosing was determined.

Athymic nu/nu female mice, 5-6 weeks old were used. On Day 0, HTB 177, 3.times.10.sup.6, was injected s.c. into the flank of 100 mice. Afterwards the mice were weighed and randomly divided into 10 groups of 10 mice per group. Drug treatment began at about 8:00 am on Day 1. The mice in groups 2, 5, 6, 7, 8, 9, and 10 were dosed p.o., b.i.d., at about 8 am and 8 pm, 7 days a week for 4 weeks. The mice in Groups 3, 4, 6, 7, 9, and 10 were dosed i.p. with the indicated dosage of Cytoxan (see Table 2) on Days 5, 12, and d 19. The primary tumors were measured once a week starting when the average size was about 50-100 mm.sup.3. The results are given in Table 3.

The Compound X (FPT Inhibitory Compound) for Groups 5, 6, 7, 8, 9, and 10 was dissolved in 40% hydroxypropylbetacyclodextran (HPBCD). Cytoxan was dissolved in sterile water.

The 80 mpk dosing solution of Compound X was made by adding 10.8 ml of 40% HPBCD to a 50 ml tube containing 176 mg of Compound X to dissolve the compound. The mixture was sonicated until a complete solution was made.

The 20 mpk dosing solution was made by placing 2 ml of the 80 mpk solution into a 15 ml tube, adding 6 ml of 40% HPBCD, and vortexing the solution to mix it.

IN VIVO COMBINATION THERAPY--B.I.D.

The effect of in vivo combination therapy of the following FPT inhibitory compound (referred to as "Compound X" in the Tables below) ##STR174## with Gemzar.RTM. (Gemcitabine HCI) on MIA PaCa xenografts (a human pancreatic carcinoma) was determined. Athymic nu/nu female mice, 7 weeks old, were used. On day 0, human pancreatic cancer MIA PaCa cells, 6.times.10.sup.6, were injected s.c. into the flank of each of 50 mice. An overview of the groups is set forth below:

Formulation: Gemzar.RTM. was dissolved in Normal Saline (Vehicle I). Compound X was dissolved in 20% hydroxy-propyl-betacyclodexatrin (Vehicle II). 0.2 ml of Compound X solution was the oral dosing volume and the i.p. dosing volume for Gemzar.RTM. was 0.1 ml.

The 80 mpk dosing solution of Compound X was made by adding 15 ml of 20% HPBCD to a 50 ml tube containing 120 mg of Compound X to dissolve the compound. The mixture was sonicated until a complete solution was made.

The Gemzar.RTM. dosing solution was made by adding 16.6 ml of Saline to a vial of Gemzar.RTM. for Injection (200 mg of gemcitabine HCI), and vortexing to mix the solution. (Gemzar.RTM. is a commercially available form of gemcitabine (2', 2'-difluoro-deoxycytidine, dFdC, Gemzar.RTM.), which is a pyrimidine analogue of deoxycytidine in which the deoxyribose moiety contains two fluorine atoms at the 2'-position. (See Heinemann et al. Cancer Res 1988 48:4024). As noted in DeVita et al. (Eds.), Cancer: Principles and Practice of Oncology (Lippencott-Raven, Phila., Pa., 5th Ed. 1997), gemcitabine is known to have a broad spectrum of antitumor activity against leukemias and solid tumors. (reference: Hertel et al., Evaluation of the antitumor activity of gemcitabine (2', 2'-difluoro-2'deoxycytidine). Cancer Res 1990, 50:4417.) According to DeVita et al., "The most commonly used clinical schedule is a 30-minute IV infusion weekly for 3 weeks followed by a 1-week rest, and the recommended dose is 1000 mg/m.sup.2. In phase II trials using this schedule (800 to 1250 dFdC mg/m.sup.2 per week), response rates in the 16% to 24% range were reported in patients with non-small cell lung cancer (previously untreated) and small cell lung cancer, breast cancer patients who had received no more than one prior regimen for metastatic disease, and patients with refractory ovarian cancer, hormone-refractory prostate cancer, and head and neck cancer." DeVita et al. (Eds.), Cancer: Principles and Practice of Oncology (Lippencott-Raven, Phila., Pa., 5th Ed. 1997).)

Protocol: Tumor cells were inoculated into 50 mice in the morning of Day 0, and the mice were weighed, randomized, and ear-marked afterwards. Drug treatments with Compound X or Vehicle II started on Day 1 and continued twice a day at 7 am and 7 pm until Day 32. Gemzar.RTM. and Vehicle I treatments started on Day 7 and continued on every 3rd day (Day 10 and Day 13). Tumor growth was quantitated by measuring tumor volumes in 3 dimensions on Day 10, 15, 21, 26, and 32.

The results are given Table 4 below:

With regard to Table 4 above, it is particularly noteworthy that while Compound X alone at 80 mpk exhibited only 57% average inhibition and Gemzar.RTM. alone at 120 mpk exhibited only 60% average inhibition, the combination of Compound X at 80 mpk plus Gemzar.RTM. at 120 mpk resulted in 88% average inhibition. The percent inhibition observed in the case of the combination of Compound X with Gemzar.RTM. is statistically significant over the percentage observed with either agent alone (p<0.05).

Compound X and Paclitaxel combination efficacy was also evaluated in the Wap-ras transgenic model. This model was used in a therapeutic mode in which treatments were initiated after mice had well developed tumors. An overview of the groups is set forth below:

Formulation: Compound X was dissolved in 20% hydroxyl-propyl-betacyclodexatrin (Vehicle I). 0.2 ml of Compound X solution is the oral dosing volume. Paclitaxel was dissolved in a diluted ethanol/cremophor EL solution (vehicle II) and the i.p. dosing volume for paclitaxel was 0.1 ml.

Protocol: The mice were weighed, randomized, and ear-marked on Day 0. Compound X treatment and Vehicle I treatment began on Day 1 and continued every 12 hours until Day 21. Paclitaxel and Vehicle II treatments started on Day 4 and continued daily on Day 5, 6, and 7.

Result: The results are illustrated in FIG. 38. Wap-ras tumors did not respond to treatment with Paclitaxel. They did respond (89% growth inhibition) to Compound X treatment at 20 mpk alone. When 20 mpk of Compound X and 5 mpk of Paclitaxel were combined, enhanced efficacy (tumor regression, equivalent to 180% growth inhibition) was seen compared to single agent alone. In addition to enhanced efficacy resulting from the combination of Compound X and Paclitaxel, the results also indicated that Compound X was able to sensitize Paclitaxel-resistant tumors.

Inert, pharmaceutically acceptable carriers used for preparing pharmaceutical compositions of the FPT inhibitors and the chemotherapeutic agents described herein can be either solid or liquid. Solid preparations include powders, tablets, dispersible granules, capsules, cachets and suppositories. The powders and tablets may comprise from about 5 to about 70% active ingredient. Suitable solid carriers are known in the art, e.g., magnesium carbonate, magnesium stearate, talc, sugar, and/or lactose. Tablets, powders, cachets and capsules can be used as solid dosage forms suitable for oral administration.

For preparing suppositories, a low melting wax such as a mixture of fatty acid glycerides or cocoa butter is first melted, and the active ingredient is dispersed homogeneously therein as by stirring. The molten homogeneous mixture is then poured into conveniently sized molds, allowed to cool and thereby solidify.

Liquid preparations include solutions, suspensions and emulsions. As an example may be mentioned water or water-propylene glycol solutions for parenteral injection. Liquid preparations may also include solutions for intranasal administration.

Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier, such as an inert compressed gas.

Also included are solid preparations which are intended for conversion, shortly before use, to liquid preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions.

The FPT inhibitors and the chemotherapeutic agents described herein may also be deliverable transdermally. The transdermal compositions can take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose.

Preferably the compounds are administered orally.

Preferably, the pharmaceutical preparation is in unit dosage form. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component, e.g., an effective amount to achieve the desired purpose.

The quantity of active compound in a unit dose of preparation may be varied or adjusted from about 0.1 mg to 1000 mg, preferably from about 1 mg to 300 mg, more preferably 10 mg to 200 mg, according to the particular application.

The actual dosage employed may be varied depending upon the requirements of the patient and the severity of the condition being treated. Determination of the proper dosage for a particular situation is within the skill of the art. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small amounts until the optimum effect under the circumstances is reached. For convenience, the total daily dosage may be divided and administered in portions during the day if desired.

The amount and frequency of administration of the FPT inhibitors and the chemotherapeutic agents and/or radiation therapy will be regulated according to the judgment of the attending clinician (physician) considering such factors as age, condition and size of the patient as well as severity of the disease being treated. A dosage regimen of the FPT inhibitors can be oral administration of from 10 mg to 2000 mg/day, preferably 10 to 1000 mg/day, more preferably 50 to 600 mg/day, in two to four (preferably two) divided doses, to block tumor growth. In a preferred embodiment, in cases where the FPT inhibitor is a fused-ring tricyclic benzocycloheptapyridine, the preferred dosage of the inhibitor is oral administration of from 50 to 600 mg/day, more preferably 50 to 400 mg/day, in two divided doses. Intermittant therapy (e.g., one week out of three weeks or three out of four weeks) may also be used.

The chemotherapeutic agent and/or radiation therapy can be administered according to therapeutic protocols well known in the art. It will be apparent to those skilled in the art that the administration of the chemotherapeutic agent and/or radiation therapy can be varied depending on the disease being treated and the known effects of the chemotherapeutic agent and/or radiation therapy on that disease. Also, in accordance with the knowledge of the skilled clinician, the therapeutic protocols (e.g., dosage amounts and times of administration) can be varied in view of the observed effects of the administered therapeutic agents (i.e., antineoplastic agent or radiation) on the patient, and in view of the observed responses of the disease to the administered therapeutic agents.

In a preferred example of combination therapy in the treatment of pancreatic cancer, the FPT inhibitor is "Compound X", as identified previously, administered orally in a range of from 50 to 400 mg/day, in two divided doses, on a continuous dosing regimen; and the antineoplastic agent is gemcitabine administered at a dosage of from 750 to 1350 mg/m.sup.2 weekly for three out of four weeks during the course of treatment.

In a preferred example of combination therapy in the treatment of lung cancer, the FPT inhibitor is "Compound X", as identified previously, administered orally in a range of from 50 to 400 mg/day, in two divided doses, on a continuous dosing regimen; and the antineoplastic agent is paclitaxel administered at a dosage of from 65 to 175 mg/m.sup.2 once every three weeks.

In a preferred example of combination therapy in the treatment of gliomas, the FPT inhibitor is "Compound X", as identified previously, administered orally in a range of from 50 to 400 mg/day, in two divided doses; and the antineoplastic agent is temozolomide administered at a dosage of from 100 to 250 mg/m.sup.2.

In another example of combination therapy, the FPT inhibitor is "Compound X", as identified previously, administered orally in a range of from 50 to 400 mg/day, in two divided doses, on a continuous dosing regimen; and the antineoplastic agent is 5-Fluorouracil (5-FU) administered either at a dosage of 500 mg/m.sup.2 per week (once a week), or at a dosage of 200-300 mg/m.sup.2 per day in the case of continuous infusion of the 5-FU. In the case of 5-FU administration on a weekly injection, 5-FU may be administered in combination with a foliate agonist (e.g., Leucovoran (at a dosage of 20 mg/m.sup.2 /week).

In the methods of this invention, an FPT inhibitor is administered concurrently or sequentially with a chemotherapeutic agent and/or radiation. Thus, it is not necessary that, for example, the chemotherapeutic agent and the FPT inhibitor, or the radiation and the FPT inhibitor, should be administered simultaneously or essentially simultaneously. The advantage of a simultaneous or essentially simultaneous administration is well within the determination of the skilled clinician.

Also, in general, the FPT inhibitor and the chemotherapeutic agent do not have to be administered in the same pharmaceutical composition, and may, because of different physical and chemical characteristics, have to be administered by different routes. For example, the FPT inhibitor may be administered orally to generate and maintain good blood levels thereof, while the chemotherapeutic agent may be administered intravenously. The determination of the mode of administration and the advisability of administration, where possible, in the same pharmaceutical composition, is well within the knowledge of the skilled clinician. The initial administration can be made according to established protocols known in the art, and then, based upon the observed effects, the dosage, modes of administration and times of administration can be modified by the skilled clinician.

The particular choice of FPT inhibitor, and chemotherapeutic agent and/or radiation will depend upon the diagnosis of the attending physicians and their judgement of the condition of the patient and the appropriate treatment protocol.

The FPT inhibitor, and chemotherapeutic agent and/or radiation may be administered concurrently (e.g., simultaneously, essentially simultaneously or within the same treatment protocol) or sequentially, depending upon the nature of the proliferative disease, the condition of the patient, and the actual choice of chemotherapeutic agent and/or radiation to be administered in conjunction (i.e., within a single treatment protocol) with the FPT inhibitor.

If the FPT inhibitor, and the chemotherapeutic agent and/or radiation are not administered simultaneously or essentially simultaneously, then the initial order of administration of the FPT inhibitor, and the chemotherapeutic agent and/or radiation, may not be important. Thus, the FPT inhibitor may be administered first followed by the administration of the chemotherapeutic agent and/or radiation; or the chemotherapeutic agent and/or radiation may be administered first followed by the administration of the FPT inhibitor. This alternate administration may be repeated during a single treatment protocol. The determination of the order of administration, and the number of repititions of administration of each therapeutic agent during a treatment protocol, is well within the knowledge of the skilled physician after evaluation of the disease being treated and the condition of the patient. For example, the chemotherapeutic agent and/or radiation may be administered first, especially if it is a cytotoxic agent, and then the treatment continued with the administration of the FPT inhibitor followed, where determined advantageous, by the administration of the chemotherapeutic agent and/or radiation, and so on until the treatment protocol is complete.

Thus, in accordance with experience and knowledge, the practising physician can modify each protocol for the administration of a component (therapeutic agent--i.e., FPT inhibitor, chemotherapeutic agent or radiation) of the treatment according to the individual patient's needs, as the treatment proceeds.

The attending clinician, in judging whether treatment is effective at the dosage administered, will consider the general well-being of the patient as well as more definite signs such as relief of disease-related symptoms, inhibition of tumor growth, actual shrinkage of the tumor, or inhibition of metastasis. Size of the tumor can be measured by standard methods such as radiological studies, e.g., CAT or MRI scan, and successive measurements can be used to judge whether or not growth of the tumor has been retarded or even reversed. Relief of disease-related symptoms such as pain, and improvement in overall condition can also be used to help judge effectiveness of treatment.
