Study Details

Brief summary:

This is an open-label, multicenter, first-in-human dose escalation and dose expansion study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of BGB-58067 alone, in combination with BG-89894 (discontinued), in combination with standard of care therapy, and in combination with novel anticancer therapies in participants with advanced solid tumors and with methylthioadenosine phosphorylase (MTAP) deficiency.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Participants must sign the Informed Consent Form and be capable of giving written informed consent
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1 or Karnofsky Performance Scale (KPS) ≥ 70
  • Life expectancy ≥ 3 months
  • Evidence of homozygous loss of MTAP or lost MTAP expression in the tumor tissue; documented RAS mutation status or KRAS mutation is required for selected cohorts
  • Able to provide tumor sample to meet the minimum tissue requirement for central MTAP deficiency testing
  • Participants with histologically or cytologically confirmed advanced, metastatic, or unresectable solid tumors, whose diseases have progressed or recurred after receiving standard systemic therapy or radiotherapy, or for whom standard systemic therapy is not available or tolerated, or would be unlikely to tolerate or derive clinically meaningful benefit from appropriate standard treatment in the opinion of the investigator; participants with advanced, metastatic, or unresectable solid tumors who have not received prior systemic treatment or have received one cycle of standard-of-care therapies will be enrolled in selected cohorts
  • Adequate organ function

Exclusion Criteria:

  • Prior treatment with any PRMT5 inhibitor or methionine adenosyltransferase 2a (MAT2A) inhibitor
  • Active leptomeningeal disease or symptomatic spinal cord compression
  • Uncontrollable pleural effusion, pericardial effusion, or ascites requiring frequent drainage
  • Any malignancy ≤ 2 years before first dose of study drug except for the specific cancer under investigation in this study and any locally recurring cancer that has been treated curatively
  • Significantly impaired pulmonary function
  • Clinically significant infections
  • Serologically active hepatitis B or C infection
  • Known human immunodeficiency virus (HIV) infection. Participants with treated HIV infection may be included in Phase 1b if they meet certain criteria
  • High cardiovascular risk factors
  • QT interval corrected by Fridericia's method (QTcF) > 470 ms based on the screening triplicate 12-lead ECG records and/or a history of additional risk factors for torsade de pointes (eg, heart failure, hypokalemia, or a family history of Long QT Syndrome)
  • Toxicities (because of prior anticancer therapy) that have not recovered to baseline or stabilized
  • Participants who are unable to swallow or with disease/procedure significantly affecting gastrointestinal function
  • Female participants who are pregnant or are breastfeeding
  • Concurrent participation in another therapeutic clinical study (participation in observational or noninterventional studies is allowed)

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Interventions and Outcome Measures

Arms

experimental: Phase 1a: BGB-58067 Monotherapy Dose Escalation and Safety Expansion

Sequential cohorts of increasing dose levels of BGB-58067 as monotherapy will be evaluated.

experimental: Phase 1a: BGB-58067 + BG-89894 Combination Therapy Dose Escalation

Sequential cohorts of increasing dose levels of BGB-58067 in combination with BG-89894 will be evaluated. Enrollment in this combination has been discontinued.

experimental: Phase 1a: BGB-58067 + Standard of Care Combination Therapy Dose Escalation

Sequential cohorts of increasing dose levels of BGB-58067 in combination with standard of care therapy will be evaluated.

experimental: Phase 1b: BGB-58067 Monotherapy Dose Expansion and Optimization

Recommended Dose(s) for Expansion (RDFE\[s\]) of BGB-58067 alone will be evaluated for selected indications and regimen(s) based on emerging data.

experimental: Phase 1b: BGB-58067 + Standard of Care Combination Therapy Dose Expansion and Optimization

RDFE(s) of BGB-58067 in combination with standard of care therapy will be evaluated for selected indications and regimen(s) based on emerging data.

experimental: Phase 1b: BGB-58067 + Novel Anticancer Therapies Combination Therapy Dose Expansion and Optimization

RDFE(s) of BGB-58067 in combination with novel anticancer therapies will be evaluated for selected indications and regimen(s) based on emerging data.
