Study Endpoints

Primary Endpoints

Progression Free Survival (PFS) in all randomized participants
From date of first dose/randomisation until disease progression or death in the absence of progression (approximately 3 years).

The analysis will include all randomized participants. All events will be included, regardless of whether the participant withdraws from therapy or receives another anticancer therapy.

Overall Survival (OS) for 3L+ participants
From date of first dose/randomisation until the date of death due to any cause (approximately 3 years).

The analysis will include all randomized participants who had at least 2 prior lines of systemic therapy. All deaths will be included, regardless of whether the participant withdraws from therapy or receives another anticancer therapy.

Objective Response Rate (ORR)
At month 6 after date of first dose

ORR is defined as the proportion of participants who have a confirmed CR or confirmed PR, as determined by the investigator per RECIST 1.1 to all dosed participants

Secondary Endpoints

OS in all randomized participants
From date of first dose/randomisation until the date of death due to any cause (approximately 3 years).
PFS for 3L+ participants
From date of first dose/randomisation until disease progression or death in the absence of progression (approximately 3 years).
Objective Response Rate (ORR) in all randomized participants

Frequently asked questions about AZD0901

What is AZD0901 used for in gastric cancer?

AZD0901 is an investigational small molecule being studied for the treatment of gastric cancer, including gastroesophageal junction adenocarcinoma. It is being evaluated in patients with advanced or metastatic disease that expresses Claudin18.2, typically as a second- or later-line therapy.

What does AZD0901 target?

AZD0901 targets Claudin18.2, a protein expressed in certain gastric and gastroesophageal junction cancers. Clinical trials are specifically enrolling participants whose tumors express Claudin18.2, making it a key biomarker for patient selection in the ongoing studies.

Who is developing AZD0901?

AZD0901 is being developed by AstraZeneca PLC, a global biopharmaceutical company listed on the stock exchange under the ticker AZN. The company is conducting multiple clinical trials to evaluate the drug's safety and efficacy in gastric cancer and other solid tumors.

What phase is AZD0901 in?

AZD0901 is currently in Phase 3 clinical development. A Phase 3 trial is comparing it with investigator's choice of therapy in second- or later-line advanced or metastatic gastric or gastroesophageal junction adenocarcinoma expressing Claudin18.2. Additional Phase 2 studies are also ongoing.

What clinical trials is AZD0901 in?

AZD0901 is being studied in three clinical trials. NCT06346392 is a Phase 3 trial in gastric and gastroesophageal junction cancer. NCT06219941 is a Phase 2 trial in advanced solid tumors including gastric, biliary tract, and pancreatic cancers. NCT07143604 is a Phase 2 trial in gastric and gastroesophageal junction adenocarcinoma.

Is AZD0901 FDA approved?

AZD0901 is not FDA approved. It is an investigational drug currently in clinical development, with active trials in Phase 2 and Phase 3 stages. The drug has not yet completed the clinical trial process required for regulatory approval.
