NCT06223256 | Recruiting Phase 1

• 1 other identifier: NBL-028-001
• Study Type: interventional
• Target: 270
• Locations: 1 country
• Sites: 1

Brief Summary

This is a multi-center, single agent study conducted in patients with advanced solid tumor types known to express Claudin 6 (CLDN6) for whom standard of care therapies are not available, are no longer effective, or not tolerated. This study consists two stages: dose-escalating and dose-expansion. Dose escalation will be guided by the Bayesian optimal interval (BOIN) design including accelerated titration to determine the maximum tolerated dose (MTD) of NBL-028. Dose expansion - Additional patients (no more than 200) will be enrolled at the recommended dose or multiple doses (if necessary) determined in the dose escalation stage. Sponsor may elect to enroll specific tumor types into four cohorts.

Drug: NBL-028

Interventions

NBL-028 DRUG

Intravenous infusion (IV), once every two weeks (one treatment cycle is 4 weeks).

NBL-028

Eligibility Criteria

• Be able to provide previously well-preserved tumor tissue sections, or agree to undergo tumor tissue biopsy for central laboratory biomarker testing.
• At least one measurable target lesion according to RECIST 1.1.
• ECOG performance status of 0 or 1 at screening.
• Life expectancy ≥3 months.
• Adequate organ function within 7 days prior to the first dose defined as: Absolute neutrophil count (ANC) ≥1.5×10\^9/L; Platelet count (PLT) ≥100×10\^9/L;.
