Brief Summary:
This is a Phase 1, open label, non-randomised, dose-escalation single agent study with expansion cohorts for dose confirmation/safety and preliminary efficacy of MCLA-145 in advanced or metastatic malignancies

Condition or disease Intervention/treatment Phase
Advanced Cancer Solid Tumor, Adult B-cell Lymphoma, Adult Drug: MCLA-145 Phase 1

Detailed Description:

Study Design: This open label, multicenter, first in human study consists of 2 parts. Part 1 is a dose escalation to find the recommended dose for the expansion.

Part 2 is a dose expansion to confirm the dose of MCLA-145 through further evaluation of safety, tolerability, Pk, preliminary antitumor activity, and functional target engagement.

The study includes three periods: Screening( up to 28 days prior to the first dose of study drug); Treatment( first dose of study drug with treatment cycles of 28 days); and Follow-up ( 30 days and 90 days after the last dose) including survival follow-up checks every 2 months up to 12 months after the last dose.

Arm Intervention/treatment
Experimental: MCLA-145
In Part 1, the dose escalation phase, patients with advanced or recurrent/metastatic solid tumors or B-cell lymphomas will receive escalating doses of MCLA-145 ( every 2 weeks ) until MTD or RDE is reached. In Part 2, the expansion phase, participants with advanced or metastatic solid tumors will receive intravenous infusion of MCLA-145 at the recommended phase II dose every 2 weeks. The duration of each treatment cycle is 28 days
Drug: MCLA-145
full-length IgG1 bispecific antibody specifically targeting PD-L1 and CD137
Other Name: bispecific

Primary Outcome Measures :
  1. Number of patients with Dose Limiting Toxicities [ Time Frame: first 28 days of treatment ]
  2. Number of patients with Adverse Events and Serious Adverse Events [ Time Frame: up to 90 days post-last dose ]

Secondary Outcome Measures :
  1. Overall response rate (ORR) [ Time Frame: Every 8 to 12 weeks until study ends, approximately 4 years ]
  2. Duration of response ( DOR) [ Time Frame: Every 8 to 12 weeks until study ends, approximately 4 years ]
  3. Disease control rate ( DCR) [ Time Frame: Every 8 to 12 weeks until study ends, approximately 4 years ]
  4. Progression Free Survival ( PFS) [ Time Frame: Every 8 to 12 weeks until study ends, approximately 4 years ]
  5. Incidence of anti-drug antibodies against MCLA-145 [ Time Frame: 12 months ]
  6. Peak plasma concentration [Cmax] [ Time Frame: 12 months ]
  7. Area under the plasma concentration versus time curve [AUC] [ Time Frame: 12 months ]
  8. Half-life [t1/2] [ Time Frame: 12 months ]
