Clinical Trials
OASIS is based on an international, multicenter, open-label phase II clinical trial. It aims to optimize the use of antibody-drug conjugates (ADCs) by identifying the most reliable tools to predict their effectiveness and side effects. The goal is to match the right ADC to the right patient at the right time.
Prospective and Retrospective Cohorts in OASIS
To better understand how patients respond to antibody-drug conjugates (ADCs), the OASIS project relies on two complementary types of patient groups, called cohorts. In the prospective cohort, patients who are currently receiving treatment are followed over time, allowing researchers to collect clinical information, medical images, and biological samples as the disease evolves. In parallel, the retrospective cohort uses existing medical data and previously collected samples from patients treated in the past. By combining these two approaches, OASIS can both observe real-time treatment outcomes and learn from past cases, helping researchers identify patterns, improve predictions, and develop more personalized and effective cancer treatments.

Trial Objectives
The main objective is to identify the most reliable tools to predict the effectiveness and side effects of ADCs, thus allowing the right ADC to be matched to the right patient at the right time.
The trial does not modify the standard treatment of patients but analyzes its effects to guide future prescriptions and improve personalized care.
