Lung Cancer Clinical Trial
A Randomized Phase II Study of Cisplatin and Etoposide in Combination With Either Hedgehog Inhibitor GDC-0449 or IGF-1R MOAB IMC-A12 for Patients With Extensive Stage
This randomized phase II trial studies cisplatin and etoposide to see how well they work when given with or without Hedgehog inhibitor GDC-0449 (vismodegib) or IGF-1R MOAB IMC-A12 (cixutumumab) in treating patients with extensive-stage small cell lung cancer. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Etoposide may slow the growth of tumor cells by blocking some of the enzymes needed for cell growth. Vismodegib may slow the growth of tumor cells. Monoclonal antibodies, such as cixutumumab, may interfere with the ability of tumor cells to grow and spread. It is not yet known whether giving cisplatin and etoposide are more effective when given together with vismodegib or cixutumumab in treating small cell lung cancer.
I. To evaluate the progression-free survival (PFS) of patients with extensive stage small cell lung cancer (SCLC-ED) treated with cisplatin and etoposide (CE), CE with hedgehog (HH) inhibitor GDC-0449 (vismodegib), and CE with insulin-like growth factor-1 receptor (IGF-1R) monoclonal antibody (IMC-A12) (cixutumumab).
I. To evaluate response rate, overall survival, and toxicity for each arm. II. To explore putative correlates of clinical benefit from combination therapy in tumor and circulating tumor cells in patients treated on this protocol.
OUTLINE: Patients are randomized to 1 of 3 treatment arms.
ARM A (CE): Patients receive cisplatin (75 mg/m^2) intravenously (IV) over 1-2 hours on day 1 and etoposide (100 mg/m^2) IV over 1-2 hours on days 1-3. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity.
ARM B (CE +GDC-0449): Patients receive cisplatin and etoposide as in Arm A and vismodegib (GDC-0449; 150 mg tablet) orally (PO) once daily (QD) on days 1-21. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients then receive vismodegib alone QD in the absence of disease progression or unacceptable toxicity.
ARM C (CE + IMC-A12): Patients receive cisplatin and etoposide as in Arm A and cixutumumab (IMC-A12; 6 mg/kg) IV over 1 hour on days 1, 8, and 15. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients then receive cixutumumab alone once weekly in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 1 year.
Histologically or cytologically confirmed small cell lung cancer (SCLC)
Extensive stage SCLC
Extensive stage disease: the extensive disease classification for this protocol includes all patients with disease sites not defined as limited stage; limited stage disease category includes patients with disease restricted to one hemithorax with regional lymph node metastases, including hilar, ipsilateral and contralateral mediastinal, and/or ipsilateral supraclavicular nodes; extensive disease patients are defined as those patients with extrathoracic metastatic disease, malignant pleural effusion, bilateral or contralateral supraclavicular adenopathy
Measurable disease based on Response Evaluation Criteria in Solid Tumors (RECIST); baseline measurements and evaluations of all sites of disease must be obtained =< 4 weeks prior to randomization
Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
Absolute neutrophil count (ANC) >= 1,500/mm^3
Platelets >= 100,000/mm^3
Total bilirubin =< 1.5 x institutional upper limit of normal (ULN)
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase)/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase) =< 3 x institutional ULN (=< 5 x ULN if liver function test [LFT] elevations are due to liver metastases)
Creatinine =< 1.5 x institutional ULN OR creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels > 1.5 x institutional ULN
Leukocytes >= 3,000/mm^3
Hemoglobin >= 9 g/dL
Fasting serum glucose < 120 mg/dL or below institutional ULN =< 7 days prior to protocol randomization
Patients with central nervous system (CNS) metastases will be eligible if they have completed a course of CNS radiotherapy and have stable neurologic function for a minimum of 28 days prior to study randomization; radiotherapy must have been completed a minimum of 28 days prior to randomization, and patients must have recovered from any adverse events related to the radiotherapy (except alopecia and grade 1 neuropathy) and have stable neurologic function for a minimum of 28 days prior to study randomization
NOTE: the use of prophylactic cranial irradiation (recommended dose 25 Gy) in those who completed protocol chemotherapy and have a response (in the absence of progressive disease [PD]) is allowed; for patients on Arms B and C, GDC-0449 and IMC-A12 will be held while patient is receiving prophylactic cranial irradiation (PCI); these agents can be reinstituted after PCI is completed
Women of child-bearing potential (WCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation
WCBP must agree to use two reliable forms of contraception simultaneously or to practice complete abstinence from heterosexual intercourse; the two methods of reliable contraception must include one highly effective method (i.e., intrauterine device [IUD], hormonal [birth control pills, injections, or implants], tubal ligation, partner?s vasectomy) and one additional effective (barrier) method (i.e., latex condom, diaphragm, cervical cap); WCBP must be referred to a qualified provider of contraceptive methods if needed
NOTE: the WCBP randomized to Arm B must agree to use two reliable forms of contraception simultaneously or to practice complete abstinence from heterosexual intercourse during the following two additional time periods related to this study: 1) while participating in the study; and 2) for at least 12 months after discontinuation from the study
Before starting the study drugs, all WCBP must have a negative pregnancy test (sensitivity of at least 50 mIU/mL); the pregnancy test must be performed within 10-14 days prior to randomization
NOTE: the WCBP randomized to Arm B must have a second pregnancy test performed within the 24 hours prior to the start of the GDC-0449; the subject may not receive GDC-0449 until the investigator has verified that the results of these pregnancy tests are negative
The WCBP randomized to Arm B will be warned that sharing the study drug is prohibited and will be counseled about pregnancy precautions and potential risks or fetal exposure; she must also agree to abstain from donating blood during study participation and at least 12 months after discontinuation from the study drug
NOTE: male subjects randomized to Arm B must agree to use a latex condom during sexual contact with WCBP while participating in the study and for at least 12 months following discontinuation from the study even if he has undergone a successful vasectomy
Male subjects randomized to Arm B will be warned that sharing study drug is prohibited and will be counseled about pregnancy precautions and potential risks of fetal exposure; male subjects must agree to abstain from donating blood, semen, or sperm during study participation and for at least 3 months after discontinuation from the study drug
