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

• Status: Active, not recruiting
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

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.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Dimethyl Sulfoxide; Trametinib

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
