Brief Summary:
Open-label, non-randomised, exploratory, phase II, multi-centre clinical trial. 43 unresectable stage III (IIIA-N2, IIIB, IIIC) KRAS p.G12C non-small cell lung cancer patients will be enrolled in this trial to evaluate the efficacy of induction treatment of AMG510 (Sotorasib) plus AMG510 (Sotorasib) treatment post-induction as measured by Progression Free Survival at 12 months.

Condition or disease Intervention/treatment Phase
Non-small Cell Lung Cancer Stage III KRAS P.G12C Drug: Sotorasib Phase 2

Detailed Description:

This is an open-label, non-randomized, exploratory, phase II multi-centre clinical trial.The total sample size is 43 patients. The population to be included are unresectable stage III (IIIA-N2, IIIB, IIIC) KRAS p.G12C non-small cell lung cancer patients.

Patients randomised will receive AMG510 (Sotorasib) 960mg once daily for 2 cycles (Q4W) in the induction phase and AMG510 (Sotorasib) 960 mg once daily (Q4W) in the treatment post-induction phase. Treatment post-induction phase only for patients with SD, PR or CR after induction treatment. This treatment will be administered until progression disease (PD), unacceptable toxicity, patient or physician's decision to discontinue or death.

The primary objective is to assess the efficacy of induction treatment of AMG510 (Sotorasib) plus AMG510 (Sotorasib) treatment post-induction as measured by Progression Free Survival at 12 (PFS12) months according to Response Evaluation Criteria in Solid Tumors (RECIST) version PFS are defined as the time from inclusion until objective tumor progression or death.

Patient accrual is expected to be completed within 5 years and a half, treatment is planned to extend for 1.5 years and the patients will be followed up for 2 years. The study will end once survival follow-up has concluded.

Primary Outcome Measures :
  1. Efficacy of the treatment in terms of the Progression Free Survival (PFS) [ Time Frame: From the date of the end of treatment until 12 months ]
    PFS defined as the length of time from the date of end of post-induction treatment to the date of the first documented progression of disease

  2. Efficacy of the treatment in terms of the Progression Free Survival (PFS) [ Time Frame: From the date of the end of treatment until 24 months ]
    PFS defined as the length of time from the date of end of post-induction treatment to the date of the first documented progression of disease


Secondary Outcome Measures :
  1. Overall response rate (ORR) of AMG510 (Sotorasib) [ Time Frame: From the date of the end of treatment until 12 months and 24 months ]
    Overall response will be assessed per RECIST v1.1 criterion. ORR is defined as the proportion of patients who have a partial or complete response to therapy; it does not include stable disease and is a direct measure of drug tumoricidal activity.

  2. Overall Survival (OS) rate of treatment with AMG510 (Sotorasib) [ Time Frame: From the date of the start of treatment until 12 and 24 months ]
    OS defined as the length of time from either the date of diagnosis or the start of the treatment that patients diagnosed with the disease are still alive.

  3. Detect and collect the sites of first failure [ Time Frame: From the date of the start of treatment until the date of last follow up, assessed up to 24 months ]
    Sites of the first failure defined as the first site of the body of documented relapse or progression of the lung cancer disease after a period of improvement.

  4. Incidence of Treatment-Emergent Adverse Events (Safety and Tolerability) [ Time Frame: From the subject written informed consent signature to 30 days from last dose of treatment. ]
    Occurrence and severity of adverse events, with severity determined by NCI CTCAE v5.0 criteria.
