Brief summary

This phase II MATCH treatment trial tests how well palbociclib (PD-0332991) works in treating patients with cancer that has certain genetic changes. Palbociclib (PD-0332991) is in a class of medications called kinase inhibitors. It is used in patients whose cancer has a certain mutation (change) in the CDK4 or CDK6 gene. It works by blocking the action of mutated CDK4 or CDK6 that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.

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 palbociclib orally (PO) once daily (QD) on days 1-21 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo computed tomography (CT) or magnetic resonance imaging (MRI) and blood sample collection throughout the trial. Patients may also undergo a biopsy on study. After completion of study treatment, patients are followed every 3 months for 2 years and then every 6 months for 1 year. THE MATCH SCREENING TRIAL: Please see NCT02465060 for information on the MATCH Screening Protocol and applicable documents.

Inclusion criteria

* Patients must have met applicable eligibility criteria in the Master MATCH Protocol EAY131/ NCI-2015-00054 prior to registration to treatment subprotocol * Patients must have CDK4 amplification or CDK6 amplification, 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 no clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g. complete left bundle branch block, third degree heart block) * Patients must not have breast cancer, mantle cell lymphoma, myeloma, or liposarcoma * Patients must not have known hypersensitivity to palbociclib or compounds of similar chemical or biologic composition * Patients with known or symptoms of left ventricular dysfunction will be excluded * Patients must not have received prior therapy with a CDK4 or CDK6 inhibitor (including but not limited to palbociclib, abemaciclib, or ribociclib) * Patients must not be using drugs or foods that are known potent CYP3A4 inhibitors or inducers, or are CYP3A substrates with narrow therapeutic indices

Design outcomes

Primary

MeasureTime frameDescription
Objective Response Rate (ORR)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 registrationORR is defined as the percentage of patients whose tumors have a complete or partial response to treatment among analyzable patients. Objective response is defined consistent with 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. Details about how to define complete response and partial response can be found in the master protocol. 90% two-sided binomial exact confidence interval is calculated for ORR.

Participant flow

Recruitment details

Subprotocol Z1C was activated on March 13, 2017. Forty-three patients were enrolled on EAY131-Z1C between March 2017 and June 2021. These patients were enrolled into 2 cohorts, a primary and an expansion cohort. The primary cohort enrolled 35 patients. This subprotocol was suspended in Oct, 2018 after meeting its original accrual goal of 35 patients. This subprotocol was reactivated in May, 2020 and subsequently closed on May 25, 2021, with 8 patients enrolled to the expansion cohort.

Pre-assignment details

Out of the 43 patients, 16 patients were enrolled on the basis of the results from the NCI-MATCH assay and 27 on the basis of the outside assay results. Twelve of the 27 outside lab patients had their samples centrally confirmed.
