AVENTINE-1: Study of AVZO-1418 as a Single Agent and in Combination Therapy in Patients With Locally Advanced or Metastatic Solid Tumors (AVZO-1418-1001)

A Phase 1/2, First-in-human Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Antitumor Activity of AVZO-1418 as a Single Agent and in Combination Therapy in Patients With Locally Advanced or Metastatic Solid Tumors

This study, the first clinical trial of AVZO-1418, aims to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, maximum tolerated dose, and antitumor activity of AVZO-1418 when administered intravenously as a monotherapy and potentially in combination therapy to patients with locally advanced or metastatic epithelial solid tumors.

This first-in-human, Phase 1/2 study will aim to obtain safety and tolerability data when AVZO-1418 is administered intravenously to patients with locally advanced or metastatic epithelial solid tumors.

Phase 1 is a dose escalation phase which will assess the safety and tolerability of AVZO-1418 and determine the maximum tolerated dose (MTD) and preliminary recommended Phase 2 dose (RP2D) of AVZO-1418 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-1418 as a monotherapy and potentially in combination therapy.
