BEACON-1: Study of AVZO-103 as a Single Agent and in Combination Therapy in Patients With Locally Advanced or Metastatic Urothelial Cancer or Other Solid Tumors (AVZO-103-1001)

Официальное название

A Phase 1/2, First-in-Human Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Antitumor Activity of AVZO-103, a Nectin4/Trop2 ADC, as a Single Agent and in Combination Therapy in Patients With Locally Advanced or Metastatic Urothelial Cancer or Other Solid Tumors

Обзор

This study, the first clinical trial of AVZO-103, aims to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, maximum tolerated dose, and antitumor activity of AVZO-103 when administered intravenously as a monotherapy and in combination therapy to patients with locally advanced or metastatic urothelial cancer or other solid tumors.

Подробное описание

Phase 1 is a dose escalation phase which will assess the safety and tolerability of AVZO-103 and determine the maximum tolerated dose (MTD) and preliminary recommended Phase 2 dose (RP2D) of AVZO-103 as a monotherapy. This data can guide selection of combination schedules and agents.

Phase 2 is a dose expansion phase that will aim to assess the antitumor activity of AVZO-103 as a monotherapy and in combination therapy.
