April 29, 2026 updated by: AstraZeneca

A Phase II Study to Evaluate the Safety, Pharmacokinetics, and Clinical Activity of AZD0171 in Combination With Durvalumab and Chemotherapy in Participants With Locally Advanced or Metastatic Solid Tumours

The proposed study is designed to examine the effects of AZD0171 and durvalumab in combination with standard-of-care chemotherapy in patients with pancreatic ductal adenocarcinoma (PDAC).

Study Overview

Detailed Description

This is a Phase II, open-label, single arm, multicentre study to assess the safety, preliminary antitumour activity, immunogenicity, pharmacodynamics (PD), and pharmacokinetics (PK) of AZD0171 in combination with durvalumab and standard-of-care chemotherapy (gemcitabine and nab-paclitaxel) in participants with first line (1L) metastatic pancreatic ductal adenocarcinoma (mPDAC).

All participants will be treated until progressive disease or unacceptable toxicity or withdrawal of consent or another discontinuation criterion is met.

The safety and tolerability of study intervention (AZD0171, durvalumab, and standard-of-care chemotherapy) was assessed. The grading scales found in the revised National Cancer Institute CTCAE latest version was utilized for all events with an assigned CTCAE grading. Grade refers to the severity of the AE. The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL. Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living (ADL); Grade 4: Life-threatening, urgent intervention required; Grade 5: Death related to AE.
