Brief Title  ICMJE First-in-human Safety and Tolerability of MP0317 in Patients With Relapsed/Refractory Advanced Solid Tumors
Official Title  ICMJE A Phase 1, First-in-human, Multicenter, Open-label, Dose-escalation Study to Characterize the Safety and Tolerability of MP0317 in Patients With Relapsed/Refractory Advanced Solid Tumors
Brief Summary This study is investigating a new experimental therapy, MP0317, a DARPin® drug candidate targeting fibroblast activation protein (FAP) and CD40. Preclinical studies suggest that MP0317 may provide benefit for the treatment of tumors known to express high levels of FAP and for which approved therapies have been exhausted. This is the first study of MP0317 in humans and its main purpose is to test its safety and tolerability in patients with advanced solid tumors. This study will also examine the blood levels of MP0317 at several increasing dose levels and a recommended dose for further development will be determined. The recommended dose will be tested in a second part of the study to confirm safety and to further assess the preliminary biologic and anti-tumor activity.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: N/A
Intervention Model: Sequential Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Advanced Malignant Solid Tumor
Intervention  ICMJE Drug: MP0317, a tri-specific fibroblast activation protein (FAP) x CD40 DARPin® drug candidate

The study will start with dose-escalation cohorts to determine the recommended dose for expansion (RDE) or the maximum tolerated dose (MTD).

Once the RDE (or MTD) has been determined, a safety expansion cohort will be opened and additional patients will be treated with MP0317 monotherapy at this dose to confirm safety in a larger population.

Study treatment will be administered every 3 weeks (q3w) as an intravenous (IV) infusion until progressive disease (PD), unacceptable toxicity, withdrawal of consent or other reasons to discontinue treatment occur, whichever comes first. Treatment beyond PD will be allowed as per Immunotherapy Response Evaluation Criteria in Solid Tumors (iRECIST).

Study Arms  ICMJE Experimental: Dose-escalation Cohorts

The starting dose is 0.03 mg/kg every 3 weeks (q3w) and up to 6 dose levels are planned.

Study treatment will be administered as an intravenous (IV) infusion until progressive disease (PD), unacceptable toxicity, withdrawal of consent or other reasons to discontinue treatment occur, whichever comes first.
