Exemestane, Pemetrexed Disodium, and Carboplatin in Treating Post-Menopausal Women With Stage IV Non-Small Cell Lung Cancer

• Proportion achieving clinical response [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
  For categorical markers Fisher's exact test will be used. The log rank test will be used to examine association between categorical markers and time to disease progression. For quantitative markers one-way ANOVA will be used. Cox-proportional hazards regression models will be used to correlate quantitative markers with time to disease progression. Pearson correlations will be used between pairs of quantitative markers. If there is significant non-normality the Kendall correlation coefficients will be used. Mixed effects models will be used to quantify markers at multiple time points.
• Quality of life in patients treated with pemetrexed disodium, carboplatin and exemestane [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
  Quality of life measures will be compared between response categories (ANOVA) and the effect of time on therapy will be assessed with mixed effects models.

This phase I trial studies the side effects and best dose of exemestane in combination with pemetrexed disodium and carboplatin in treating post-menopausal women with stage IV non-small cell lung cancer. Exemestane may stop the growth of tumor calls by blocking some of the enzymes need for cell growth. Drugs used in chemotherapy, such as pemetrexed disodium and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving exemestane together with pemetrexed disodium and carboplatin may kill more tumor cells

PRIMARY OBJECTIVES:

I. Evaluate the safety and tolerability of escalating doses of exemestane when given with pemetrexed (pemetrexed disodium) and carboplatin in post-menopausal women with stage IV non-squamous, non-small cell lung cancer (NSCLC).

SECONDARY OBJECTIVES:

I. Determine the objective tumor response rate (defined by Response Evaluation Criteria in Solid Tumors [RECIST] 1.1) in patients treated with pemetrexed, carboplatin and exemestane.

II. Evaluate the pharmacokinetic profile of pemetrexed, carboplatin and exemestane.

III. Evaluate quality of life in patients treated with pemetrexed, carboplatin and exemestane.

IV. Analyze tumor tissue biomarkers for potential correlation with response.

OUTLINE: This is a dose-escalation study of exemestane.

Patients receive exemestane orally (PO) once daily (QD) on days 1-28 and pemetrexed disodium intravenously (IV) over 15 minutes and carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, and then every 3 months thereafter.

• Measurable disease according to modified RECIST version 1.1
• Eastern Cooperative Oncology Group (ECOG) performance status =< 1
• Expected survival time of >= 3 months in the opinion of the investigator
• Postmenopausal women; women are eligible if they are postmenopausal (older than 50 years of age with no spontaneous menses for at least 12 months; or 50 years of age or younger either with no spontaneous menses [amenorrheic] within 12 months of randomization [e.g., spontaneous or secondary to hysterectomy] and a follicle-stimulating hormone level within the postmenopausal range or with prior bilateral oophorectomy)
• Ability to provide a formalin-fixed, paraffin-embedded (FFPE) tumor tissue sample containing representative tumor tissue from a previously obtained biopsy/resection that meets specific tissue sample requirements at screening

Exclusion Criteria:

• History of another primary cancer within 3 years prior to day 1 with the exception of curatively treated skin cancer (other than melanoma) or curatively treated cervical carcinoma in-situ
• Untreated central nervous system (CNS) involvement; (treated CNS involvement is permitted only if the patient is not currently on steroid therapy or has remained on a stable, unchanged dose of steroid for >= 3 weeks)
• Recent major surgery within the prior 4 weeks; (mediastinoscopy or placement of a central venous access will be allowed as long as placement was more than 7 days prior to receiving study drug)
• Any prior or concurrent investigational or standard therapy for treatment of metastatic NSCLC including radiation therapy, chemotherapy, biological therapy (with the exception of a single treatment regimen of a tyrosine kinase inhibitor as a single agent, which must be completed 28 days prior to day 1), hormonal therapy, or immunotherapy; (palliative-targeted radiotherapy for brain or bone metastases is permitted providing it has been at least 14 days prior to day 1)
• History of hormone replacement therapy (estrogens with or without progestin) or an aromatase inhibitor (anastrazole, letrozole, exemestane) within 8 weeks prior to day 1
• Osteoporosis complicated by pathologic fracture
