A Study Evaluating the Activity of Anti-cancer Treatments Targeting Tumor Molecular Alterations/Characteristics in Advanced / Metastatic Tumors. (MegaMOST)

March 26, 2024 updated by: Centre Leon Berard

MegaMOST - A Multicenter, Open-label, Biology Driven, Phase II Study Evaluating the Activity of Anti-cancer Treatments Targeting Tumor Molecular Alterations /Characteristics in Advanced / Metastatic Tumors.

This trial is a multicenter, open-label, biology driven, phase II study using a sequential Bayesian design, aiming to assess the efficacy and safety of different Matched Targeted Therapy (MTT) in independent and parallel cohorts of treatment.

Patients will be assigned to a treatment cohort based on molecular alterations/characteristics detected on tumor sample from primary tumor or metastatic lesion.

In this protocol, several MTTs treatment cohorts are planned. This study is designed with the flexibility to open new MTTs treatment cohorts and to close existing MTTs treatment cohorts that demonstrate no clinical benefit. Each treatment cohort will be driven separately even though procedures, quality control and reporting, will be common. The protocol will be amended in order to include new treatments or combinations that emerge as being of interest for patients with advanced/metastatic cancers.

All eligible patients will receive study drugs as long as patient experiences clinical benefit in the opinion of the investigator, or until unacceptable toxicity, or until symptomatic deterioration attributed to disease progression as determined by the investigator after an integrated assessment of radiographic data and clinical status, or withdrawal of consent.

Patients will be permitted to continue study treatment after progressive disease according to RECIST v1.1 if they meet all of the following criteria and following validation of the Sponsor:

  • Evidence of clinical benefit as assessed by the investigators,
  • Absence of symptoms and signs (including worsening of laboratory values; e.g., new or worsening hypercalcemia) that indicate unequivocal progression of disease,
  • No decline in ECOG Performance Status (PS) that can be attributed to disease progression.
