Evaluating targeted cancer treatments based on tumor characteristics in advanced tumors

Official title: 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.

Run by Centre Leon Berard · NCT04116541 · Data updated 2026-11-12

This study is testing if personalized cancer treatments based on the specific characteristics of a patient's advanced tumor can help them when standard treatments aren't working.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with histologically confirmed metastatic or unresectable locally advanced malignancies that are resistant to standard therapies.

Probably not a fit

Patients whose tumors do not have actionable molecular alterations or who are not eligible for the specified treatment cohorts may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, open-label, phase II trial aims to assess the efficacy and safety of matched targeted therapies (MTT) for patients with advanced or metastatic solid tumors. Patients will be assigned to specific treatment cohorts based on molecular alterations identified in their tumor samples. The study employs a flexible design that allows for the addition of new treatment cohorts and the closure of those that show no clinical benefit. The goal is to provide personalized treatment options for patients whose cancers are resistant to standard therapies.

Why it matters

Potential benefit: If successful, this study could lead to more effective personalized treatment options for patients with advanced cancers.

How similar studies have gone: Other studies have shown promise in using targeted therapies based on molecular characteristics, indicating a potential for success in this approach.

  * Cohort Trametinib : Activating mutation and/or amplification of KRAS (except all KRAS G12 mutations), NRAS, HRAS and/or MAP2K; and/or biallelic inactivation of NF1; and/or activating mutation PTPN11; and/or amplification or translocation of BRAF, and/or translocation RAF1
  * Cohort Trametinib + Dabrafenib : BRAF V600 mutation and/or rearrangement of BRAF following validation by central molecular tumor board of Centre Léon Bérard.
  * Cohort Avapritinib : Activating mutations of KIT exon 17 or PDGFRA exon 18 associated or not to mutation on KIT exon 11 or PDGFRA exon 12/14
* Previously treated by at least one prior line of treatment in the advanced/metastatic setting except for specific tumor type with no standard treatment approved and reimbursed in France following sponsor approval.
* Documented radiological disease progression as per RECIST v1.1 and presence of at least one measurable lesion according to RECIST 1.1 criteria based on screening tumor assessment.
* Performance Status score of 0 or 1 according to the Eastern Cooperative Oncology Group (ECOG) scale.
* Adequate organ function
* Adequate cardiovascular function
* Specific toxicities related to any prior anti-cancer therapy must have resolved to grade ≤1 , except for alopecia (all grades), grade 2 neuropathy or anemia.
* Unless infertility is proven, men must agree to use effective contraception
* Women of child-bearing potential must have a negative serum pregnancy test within 7 days of first dose of study drug and agree to use effective contraception
* Patient should understand, sign, and date the written voluntary informed consent form prior to any protocol-specific procedures performed. Patient should be able and willing to comply with study procedures as per protocol.
* Patient must be covered by a medical insurance.

Exclusion Criteria:

* Patients amenable to therapy with curative intent.
* Patients participating to another clinical trial with a medicinal product.
* Patients previously treated with similar MTT meaning any agent targeting the same signaling pathways components.
* Patients unable to swallow oral medication.
* Patients with known hypersensitivity to excipients
* Patients with symptomatic central nervous system (CNS) metastasis who are neurologically unstable or require increasing doses of corticosteroids or local CNS-directed therapy to control their CNS disease.
* Patients with secondary malignancy unless this malignancy is not expected to interfere with the evaluation of study endpoints and is approved by the sponsor. Examples of the latter include: basal or squamous cell carcinoma of the skin, in-situ carcinoma of the cervix, localized prostate cancer, prior malignancy and no evidence of recurrence for ≥ 2 years.
* Patients using, or requirement to use while on the study, or not respecting the minimal wash-out period of medications
* Any clinically significant and/or uncontrolled medical disease that could compromise the patient's ability to tolerate study drug or would likely interfere with study procedures or results.
* Patients with known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
* Patients who are pregnant or breastfeeding women or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through after the last dose of trial treatment (depanding on cohort).
