Official title

A Phase 1b/2, First-in-Human, Dose Escalation and Expansion Study of XMT-1536 In Patients With Solid Tumors Likely to Express NaPi2b

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

First-in-human, Phase 1b/2 safety study of the antibody-drug conjugate (ADC) XMT-1536 (upifitamab rilsodotin) administered as an intravenous infusion once every four weeks. Patients with tumor types likely to express NaPi2b were enrolled in dose escalation. Patients with platinum-resistant ovarian cancer and non-small cell lung cancer (adenocarcinoma subtype) were enrolled in the expansion segment of this study. Patients with platinum-resistant, high-grade serous ovarian cancer were enrolled in the UPLIFT segment of this study. In addition to safety assessments, the pharmacokinetics of the drug were assessed along with ADC activity. A QTc sub-study was added for the UPLIFT cohort for a sub-set of sites.
