Sirolimus and Auranofin in Treating Patients With Advanced or Recurrent Non-Small Cell Lung Cancer or Small Cell Lung Cancer

PRIMARY OBJECTIVES:

I. To establish the maximum tolerated dose of auranofin plus sirolimus after at least one line of platinum based chemotherapy for lung cancer (squamous, ras-mutated adenocarcinoma, or small cell lung cancer) patients with no acceptable standard treatment options. (Phase I) II. To assess the progression-free survival at four months of patients treated with auranofin after at least one line of platinum based chemotherapy for lung cancer (squamous, ras-mutated adenocarcinoma, or small cell lung cancer) patients with no acceptable standard treatment options. (Phase II)

SECONDARY OBJECTIVES:

I. To assess the overall survival in this population in comparison to recent historical controls.

II. To determine the adverse events (AE) profile and safety of the regimen. III. To determine the overall response rate, per Response Evaluation Criteria In Solid Tumors (RECIST) criteria, and duration of tumor response in those patients with measurable disease.

TERTIARY OBJECTIVES:

I. To assess the relationship between molecular correlates and progression-free survival (PFS), overall survival (OS), response and adverse events.

OUTLINE: This is a phase I, dose-escalation study of auranofin followed by a phase II study.

Patients receive auranofin orally (PO) on days 1-28 and sirolimus PO on days 1-28 (days 8-28 of course 1). Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3-6 months for 5 years.

Inclusion criteria

• Histologic or cytologic confirmation of lung cancer (squamous, ras-mutated adenocarcinoma or small cell lung cancer)

Exclusion criteria

• Any of the following:

• Pregnant women
• Nursing women
• Men or women of childbearing potential who are unwilling to employ adequate contraception
• Symptomatic, untreated, or uncontrolled central nervous system (CNS) metastases or seizure disorder; NOTE: patients with treated CNS metastases without evidence of progression and without uncontrolled symptoms or need for steroids may enroll
• Human immunodeficiency virus (HIV)-positive patients receiving combination anti-retroviral therapy are excluded
• Unwilling or unable to, comply with the protocol
• Any of the following prior therapies:

• Radiation to >= 25% of bone marrow
• Major surgery (i.e., laparotomy), open biopsy, or significant traumatic injury =< 4 weeks prior to registration; minor surgery =< 2 weeks prior to registration; insertion of a vascular access device is not considered major or minor surgery in this regard

• Cardiac arrhythmia
• Poorly controlled diabetes
• Interstitial pneumonia or extensive and symptomatic interstitial fibrosis of the lung
• Active or recent history of hemoptysis; if hemoptysis has resolved with measures such as palliative radiation therapy (e.g. 3000 cGy over 10 fractions), arteriographic embolization or endobronchial interventions (e.g. photodynamic therapy, brachytherapy), etc. for > 14 days, patients may be considered for participation in this study

• Use of St. John's Wort because of its effects on hepatic drug metabolism
• Other active malignancy: EXCEPTIONS: Non-melanoma skin cancer, localized prostate cancer, or carcinoma-in-situ of the cervix; NOTE: If there is a history or prior malignancy, patient must not be receiving other cytotoxic or molecularly targeted therapeutics treatment for their cancer; patients receiving certain hormonal manipulations as part of their treatment may be allowed to continue at the discretion of the Principal Investigator (PI) (e.g. luteinizing hormone-releasing hormone [LHRH] analogs for prostate cancer)
• Unable to discontinue use of potent cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inhibitors/inducers
