Phase I clinical trial - Phases précoces tumeurs solides

The dose escalation part (Part A) of the study will evaluate the safety and tolerability of escalating doses of NI-1801, administered intravenously (IV) over 1 to 2 hour(s), to determine the maximum tolerated dose (MTD) and non-tolerated toxic dose (NTD) of both the first dose and subsequent doses of NI-1801. The expansion part (Part B) will further evaluate the safety and efficacy of NI-1801 administered at or below the MTD in up to 20 subjects in order to determine the recommended Phase 2 dose (RP2D). Treatments will be administered in 28-day cycles for up to 6 months until confirmed disease progression, unacceptable toxicity, or subject/Investigator decision to withdraw. NI-1801 treatment can extend beyond 6 cycles for those patients who do not have disease progression.
