Testing Trametinib as a Potential Targeted Treatment in Cancers With GNAQ or GNA11 Genetic Changes (MATCH-Subprotocol S2)

Found through the registry condition index, not selected as a treatment recommendation. This discovery collection was restricted to studies with posted results.

Phase: PHASE2
Status at capture: ACTIVE NOT RECRUITING
Registry last update: 2026-07-17

This phase II MATCH treatment trial identifies the effects of trametinib in patients whose cancer has genetic changes called GNAQ or GNA11 mutations. Trametinib may block proteins called MEK1 and MEK2, which may be needed for cancer cell growth when GNAQ or GNA11 mutations are present. Researchers hope to learn if trametinib will shrink this type of cancer or stop its growth.

Who could take part

eligibility Criteria: Inclusion Criteria: * Patients must have met applicable eligibility criteria in the Master MATCH Protocol prior to registration to treatment subprotocol * Patients must have GNAQ or GNA11 mutations, or another aberration, as determined via the MATCH Master Protocol * Patients must have an electrocardiogram (ECG) within 8 weeks prior to treatment assignment and must have NONE of the following cardiac criteria: * Clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g. complete left bundle branch block, third degree heart block) * Treatment-refractory hypertension defined as a blood pressure of systolic \> 140 mmHg and/or diastolic \> 90 mmHg which cannot be controlled by anti-hypertensive therapy * Patients must have an echocardiogram (ECHO) or a nuclear study (multigated acquisition scan \[MUGA\] or First Pass) within 4 weeks prior to registration to treatment and must not have a left ventricular ejection fraction (LVEF) \< the institutional lower limit of normal (LLN). If the LLN is not defined at a site, the LVEF must be \> 50% for the patient to be eligible * Patients who previously received monoclonal antibody therapy (e.g., ipilimumab, nivolumab, pembrolizumab and others) must have stopped the prior therapy for 8 or more weeks before starting on trametinib * Patients with glioblastoma must have histologically or radiographically confirmed recurrent or progressive World Health Organization (WHO) grade 4 glioma (glioblastoma). * NOTE: All baseline and post-baseline disease assessments must be performed using contrast-enhanced cranial magnetic resonance imaging (MRI) or contrast-enhanced computed tomography (CT) for subjects who cannot have MRI performed Exclusion Criteria: * Patients with a history of interstitial lung disease or pneumonitis are excluded * Patients must not have known hypersensitivity to trametinib or compounds of similar chemical or biologic composition or to dimethyl sulfoxide (DMSO) * Patients must not have a history or current evidence/risk of retinal vein occlusion (RVO). An eye exam is required at baseline * Patients who previously received prior treatment with other MEK inhibitors (including, but not limited to, trametinib, binimetinib, cobimetinib, selumetinib, RO4987655 \[CH4987655\], GDC-0623 and pimasertib) will be excluded * Patients with uveal melanoma are excluded

primary Outcomes

description
Overall response rate was defined as the proportion of patients with best overall response of complete response (CR) or partial response (PR) among all eligible and treated patients. Best overall response was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Please refer to the protocol for the detailed definitions of response criteria. The 90% two-sided binomial exact confidence interval was calculated for ORR.
measure
Objective Response Rate (ORR)
time Frame
Tumor assessments occurred at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration

secondary Outcomes

description
Progression free survival is defined as time from treatment start date to date of progression or death from any cause, whichever occurs first. Disease progression was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Please refer to the protocol for detailed definitions of disease progression. 6 month PFS rate was estimated using the Kaplan-Meier method, which can provide a point estimate for any specific time point.

6-month Progression-free Survival (PFS) Rate

Full study description

brief Summary: This phase II MATCH treatment trial identifies the effects of trametinib in patients whose cancer has genetic changes called GNAQ or GNA11 mutations. Trametinib may block proteins called MEK1 and MEK2, which may be needed for cancer cell growth when GNAQ or GNA11 mutations are present. Researchers hope to learn if trametinib will shrink this type of cancer or stop its growth.
detailed Description: PRIMARY OBJECTIVE: I. To evaluate the proportion of patients with objective response (OR) to targeted study agent(s) in patients with advanced refractory cancers/lymphomas/multiple myeloma. SECONDARY OBJECTIVES: I. To evaluate the proportion of patients alive and progression free at 6 months of treatment with targeted study agent in patients with advanced refractory cancers/lymphomas/multiple myeloma. II. To evaluate time until death or disease progression. III. To identify potential predictive biomarkers beyond the genomic alteration by which treatment is assigned or resistance mechanisms using additional genomic, ribonucleic acid (RNA), protein and imaging-based assessment platforms. IV. To assess whether radiomic phenotypes obtained from pre-treatment imaging and changes from pre- through post-therapy imaging can predict objective response and progression free survival and to evaluate the association between pre-treatment radiomic phenotypes and targeted gene mutation patterns of tumor biopsy specimens. OUTLINE: Patients receive trametinib dimethyl sulfoxide (trametinib) orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months if less than 2 years from study entry, and then every 6 months for year 3 from study entry.
