Advanced Lung Cancer Treatment With Metformin and Chemo-Radiotherapy

Phase 2

Terminated

• Conditions: Lung Cancer
• Interventions: Drug: Metformin plus Chemo-radiotherapy; Radiation: Chemo-radiotherapy

• Registration Number: NCT02115464
• Lead Sponsor: Ontario Clinical Oncology Group (OCOG)

Brief Summary

ALMERA is a randomized, phase II, open label study in patients with locally advanced non-small cell lung cancer (NSCLC) which will compare standard radiotherapy plus concurrent chemotherapy with or without consolidation versus the same treatment plus concurrent Metformin continuing for 12 months. Metformin is a well tolerated and inexpensive drug that has the potential to improve cancer patient outcomes.

Detailed Description

This is a randomized, phase II, open label study in patients with locally advanced NSCLC which will compare standard RT (60-63 Gy for 6 weeks) plus concurrent Cisplatin-based chemotherapy (CRT) with or without consolidation (standard arm) vs the same CRT with or without consolidation plus treatment with Metformin concurrent with CRT and continuing for a total of 12 months (experimental arm). Ninety-four eligible and consenting patients will be randomized to one of the two treatment arms. Patients randomized to the experimental arm will receive Metformin (2000 mg/day) for a period of 12 months. Patients will be continuously evaluated for toxicity, will be assessed weekly at clinic visits during concurrent CRT treatment with or without consolidation and at follow up clinic visits at 3, 6, 9 and 12 months (from the date of randomization). Disease progression will be evaluated every 3 months for up to 12 months. All patients will be followed for up to 24 months (2 years) for survival.

The primary objective of this study is to determine the effect of Metformin on the proportion of patients free of disease progression at 12 months after initiation of drug treatment.

Arm && Interventions

Group	Intervention	Description
Metformin plus Chemo-radiotherapy	Metformin plus Chemo-radiotherapy	Metformin orally 500 mg twice daily for the first week, 1500 mg a day in week 2 and 2000 mg a day at week 3 and then for a period of 12 months. Cisplatin-based chemotherapy with or without consolidation with standard radiotherapy of 60-63 Gy for 6 weeks.
Chemo-radiotherapy	Chemo-radiotherapy	Concurrent cisplatin based chemotherapy with or without consolidation and radiotherapy of 60-63 Gy for 6 weeks.

Primary Outcome Measures

Name	Time	Method
Progression free survival	12 months	Progression free survival illustrates loco-regional disease control and freedom from distant metastasis

Secondary Outcome Measures

Name	Time	Method
Time to loco-regional progression	18-24 months	Time to loco-regional progression is defined from the date of randomization until the date of confirmed loco-regional progression
Toxicities	12 months plus 30 days	The adverse event reporting period begins from the time of randomization and ends 30 days after the last treatment (concurrent chemo-radiotherapy plus or minus Metformin). Only adverse events assessed as Grade 3 or higher will be documented.
Overall survival	18-24 months	Overall survival will be defined from the date of randomization until the date of death due to any cause.
Distant progression-free survival	18-24 months	Distant progression-free survival is defined from the date of randomization until the date of distant progression, or death due to any cause.
