Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Dose response, Pharmacodynamic, Therapy, Efficacy, Safety, Pharmacokinetic

To determine the safety and tolerability and to establish a preliminary maximum tolerated dose/recommended Phase 2 dose of MK-1088 administered as monotherapy and in combination with pembrolizumab infusion in Part 1

Secondary objectives 2

  1. To evaluate the PK of MK-1088 administered as monotherapy and in combination with pembrolizumab infusion in Part 1 and in Part 2
  2. To evaluate the antitumor activity (objective response rate [ORR] based on PCWG-modified RECIST 1.1 [prostate cancer participants only] or RECIST 1.1 [all other participants]) of MK-1088 as assessed by the investigator when used as monotherapy and in combination with pembrolizumab in Part 1 and in Part 2

#TitleAllocationBlindingRoles blindedArms
1 Dose escalation
Participants will receive treatment with MK-1088 as monotherapy (Arm 1) or as combination therapy with pembrolizumab (Arm 2). Study treatment will begin on Day 1 of each 21-day cycle. Participants enrolled in Arm 1 and in Arm 2 may continue treatment for up to 35 cycles (approximately 2 years) from the start of treatment.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 3

  1. Has a histologically- or cytologically-confirmed diagnosis of advanced/metastatic solid tumor by pathology report and have received, have been intolerant to, or have been ineligible for treatment known to confer clinical benefit
  2. For metastatic castrate-resistant prostate cancer (mCRPC) only: (1) Must have previously received docetaxel, prior treatment with one other chemotherapy is allowed as well as up to 2 second-generation hormonal manipulations and (2) have prostate cancer progression within 6 months before screening, as determined by the investigator
  3. If human immunodeficiency virus (HIV) positive, has well-controlled HIV on anti-retroviral therapy (ART)

Exclusion criteria 18

  1. Has had chemotherapy, definitive radiation, or biological cancer therapy within 4 weeks (2 weeks for palliative radiation) before the first dose of study intervention
  2. Has a history of a second malignancy, unless potentially curative treatment has been completed with no evidence of malignancy for 2 years
  3. Has clinically active central nervous system (CNS) metastases and/or carcinomatous meningitis
  4. Has an active infection requiring therapy
  5. Has a history of interstitial lung disease
  6. Has a history of (noninfectious) pneumonitis that required steroids or current pneumonitis
  7. Has an active autoimmune disease that has required systemic treatment in the past 2 years
  8. Has concurrent active Hepatitis B and Hepatitis C virus infection
  9. Has HIV with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease
  10. Has not fully recovered from any effects of major surgery without significant detectable infection
  11. Has a history or current evidence of a gastrointestinal (GI) condition or impaired liver function or diseases that in the opinion of the investigator may significantly alter the absorption or metabolism of oral medications
  12. Has clinically significant cardiovascular disease within 12 months from first dose of study intervention, including NYHA Class III or IV congestive heart failure, unstable angina, myocardial infarction, cerebral vascular accident, or cardiac arrhythmia associated with hemodynamic instability
  13. Has a QTcF >470 msec
  14. Has history of an allogeneic stem cell transplant or a solid organ transplant
  15. Has received prior systemic anticancer therapy including investigational agents within 4 weeks before allocation
  16. Has received prior radiotherapy within 2 weeks of start of study intervention, or had radiation-related toxicities requiring corticosteroids
  17. Has received a live or live-attenuated vaccine within 30 days before the first dose of study intervention
  18. Has a "superscan" bone scan
