A Phase Ib Study of MEK162 Plus BYL719 in Adult Patients With Selected Advanced Solid Tumors

This study is ongoing, but not recruiting participants.

First received: October 6, 2011

Last verified: February 2017
This is a multi-center, open-label, dose-finding, phase Ib study to estimate the maximum tolerated dose(s) (MTD(s)) and/or recommended dose(s) for expansion (RDE(s)) for the orally administered combination of BYL719 and MEK162. This combination will be explored in adult patients with advanced CRC, esophageal cancer, pancreatic cancer, NSCLC, ovarian cancer, or other advanced solid tumors and in adult patients with AML or high risk and very high risk MDS, with documented RAS or BRAF mutations. Dose escalation will be guided by a Bayesian logistic regression model with overdose control. At MTD or RDE, four expansion arms will be opened in order to further assess the safety and preliminary activity of the combination of BYL719 and MEK162 in specific patient populations.

Official Title: A Phase Ib Open-label, Multi-center, Dose Escalation and Expansion Study of Orally Administered MEK162 Plus BYL719 in Adult Patients With Selected Advanced Solid Tumors

Further study details as provided by Array BioPharma:

Primary Outcome Measures:
  • Incidence of Dose Limiting Toxicities (DLT) [ Time Frame: during the first cycle (28 days) of treatment with BYL719 and MEK162 ]
    Toxicity will be assessed using the National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE), version 4.0 unless otherwise specified. A DLT is defined as an adverse event or abnormal laboratory value assessed as at least possibly related to the study medication, occurs ≤ 28 days following the first dose of BYL719 and MEK162 (Cycle 1), and meets any of the protocol-specified DLT criteria.

Secondary Outcome Measures:
  • Number of participants with adverse events and serious adverse events [ Time Frame: Assessed from Cycle 1 Day 1 until treatment discontinuation ]
    All AEs and SAEs will be collected in accordance with the protocol and assessed for relatedness to study drug combination.

  • Overall response rate [ Time Frame: Assessed every 8 weeks until disease progression ]
    Overall response rate (ORR) is the proportion of patients with a best overall response of Complete Response (CR) or Partial Response (PR).

  • Time to progression [ Time Frame: Assessed every 8 weeks until disease progression ]
    Time to progression (TTP) is the time from date of randomization/start of treatment to the date of event defined as the first documented progression or death due to underlying cancer. If a patient has not had an event, time to progression is censored at the date of last adequate tumor assessment.

  • Progression free survival [ Time Frame: Assessed every 8 weeks until disease progression ]
    Progression-free survival (PFS) is the time from date of randomization/start of treatment to the date of event defined as the first documented progression or death due to any cause. If a patient has not had an event, progression-free survival is censored at the date of last adequate tumor assessment.

  • Time versus plasma concentration profiles of BYL719 and MEK162 [ Time Frame: Assessed during the first cycle of treatment ]
    Blood concentrations of MEK162 and its metabolite (AR00426032) and BYL719 will be assessed during the first cycle of treatment.

  • Correlation of baseline mutation or amplification status (PIK3CA, KRAS, NRAS and BRAF) and clinical anti-tumor activity outcome [ Time Frame: Assessed at Baseline (pre-treatment) ]
    Collect baseline genetic mutation/alteration status to investigate the potential relationship to anti-tumor activity.

  • Clinical benefit rate [ Time Frame: Assessed every 4 weeks for 3 months and every 3 months for 6 months followed by every 6 months thereafter until disease progression ]
    The clinical benefit rate is defined as the proportion of patients with complete remission, complete remission with incomplete blood count recovery, partial remission, minor response or stable disease for > 15 weeks

Estimated Enrollment: 138

Estimated Study Completion Date: December 31, 2018
Primary Completion Date: August 31, 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
