About this trial

This phase II trial studies the effect of avapritinib in treating malignant solid tumors that have a genetic change (mutation) in CKIT or PDGFRA and have spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). Avapritinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Avapritinib may help to control the growth of malignant solid tumors.

Eligibility criteria

Qualifiers

The patient (or legally acceptable representative if applicable) provides written informed consent for the study.

Male or female ≥18 years of age on the day of informed consent signing. Adolescent patients aged 12 years and older are allowed with signed assent and parental consent according to institutional guidelines and requirements.

Cohorts 1 and 2: Patient has a locally advanced or metastatic solid tumor and has progressed on appropriate standard therapy, has not shown clinically meaningful benefit to appropriate standard therapy, has no available standard therapy, or has declined appropriate standard therapy.

Cohort 3: Patient has newly diagnosed IDH wild-type, MGMT-unmethylated glioblastoma. Patients must have received prior treatment with radiation and concurrent temozolomide per standard of care.27 Patients must have completed radiation and concurrent temozolomide 3-8 weeks prior to study treatment initiation.

Disqualifiers

Patients who have GIST.

Patients with tyrosine kinase inhibitor-resistant CKIT mutation V654A or T670I.

Patients with meningeal carcinomatosis, leptomeningeal carcinomatosis, spinal cord compression, or symptomatic or unstable brain metastases. Note: Patients with stable brain metastases (defined as asymptomatic or no requirement for high-dose or increasing dose of systemic corticosteroids) and without imminent need of radiation therapy) are eligible (including those with untreated brain metastases). If applicable, patients must have completed brain radiation therapy and recovered adequately from any associated toxicity and/or complications prior to eligibility assessment. For patients who have received prior radiation therapy, post-treatment magnetic resonance imaging scan should show no increase in brain lesion size/volume.

History of documented congestive heart failure (New York Heart Association functional classification III-IV) or serious cardiac arrhythmias requiring treatment.
