FiH Study to Investigate Safety, PK and Efficacy of the NaPi2b ADC TUB-040 in Patients With PROC or r/r Adenocarcinoma NSCLC (NCT06303505)

A First-in-human Dose Escalation and Optimization Phase I/IIa Study to Investigate Safety, Tolerability, PK, and Efficacy of the NaPi2b ADC TUB-040 in Patients With Platinum-resistant High-grade Ovarian Cancer (PROC) or r/r Adenocarcinoma Non-small Cell Lung Cancer (NSCLC)

🟢 Recruiting Phase1 / Phase2 💊 Investigational Drug / Biologic Sponsor: Tubulis GmbH

🩺 Plain-English Summary (8th-Grade Level)

The purpose of this multicentric, open label trial (NAPISTAR 1-01) is to evaluate the safety/tolerability, pharmacokinetics and preliminary efficacy of TUB-040 and to find the best dose of TUB-040 in patients with ovarian cancer and Non Small Cell Lung Cancer. TUB-040 is an antibody-drug-conjugate which delivers a topoisomerase I inhibitor to tumor cells which overexpress the target NaPi2b. The study consists of two parts: In dose escalation, ovarian cancer patients and lung cancer patients receive increasing doses of TUB-040 until the maximal tolerated dose is found. In dose optimization, at least two doses are compared with each other to determine which dose is optimal for patients. TUB-040 is given IV every 3 weeks until the disease progresses or the patient has to stop due to side effects.
