Registration Number
NCT06219941
Lead Sponsor
AstraZeneca
Brief Summary

The purpose of this study is to assess the safety, tolerability, efficacy, pharmacokinetics (PK), and immunogenicity of AZD0901 as monotherapy and in combination with anti-cancer agents in participants with locally advanced unresectable or metastatic solid tumours expressing CLDN18.2.

Detailed Description

This open-label, multi-centre study consists of individual sub studies, each evaluating the safety and tolerability of AZD0901.

Sub study 1 will investigate the safety, tolerability, and anti-tumour activity of AZD0901 monotherapy in participants with advanced or metastatic gastric esophageal cancer expressing CLDN18.2. Participants will receive AZD0901 monotherapy via intravenous (IV) infusion and will be randomised in to one of 2 arms.

Sub study 2 will consist of two parts, a safety run-in and a dose expansion part to investigate the safety and efficacy of AZD0901 in combination with different chemotherapy agents in participants with pancreatic cancer. Substudy 3 will investigate the safety, tolerability, and anti-tumour activity of AZD0901 monotherapy in participants with advanced or metastatic Biliary tract cancer.

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR).From date of first dose of AZD0901 up until progression, or the last evaluable assessment in the absence of progression (approximately 2 years).

Proportion of participants with a confirmed Complete Response (CR) or Partial Response (PR) as determined by the Investigator at local site as per RECIST v1.1.

Incidence of adverse events (AEs), serious AEs (SAEs). Changes from baseline in clinical laboratory parameters, vital signs, ECGs and physical examination. Rate of AEs leading to discontinuation of AZD0901, Occurrence of DLTs.30 days post treatment completion. AE Follow Up for 90 days post AZD0901 discontinuation.

To investigate the safety and tolerability, of AZD0901 monotherapy or in combination with anti-cancer agents in particpants with advanced or metastatic solid tumours expressing CLDN18.2.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS)From date of first dose/randomisation until the date of death due to any cause (approximately 2 years).

The analysis will include all dosed/randomised participants as assigned/randomised. All deaths will be included, regardless of whether the participant withdraws from therapy or receives another anticancer therapy.

Progression Free Survival (PFS)From date of first dose/randomisation until disease progression or death in the absence of progression (approximately 2 years).

Progression-free survival is defined as the time date of randomisation or enrollment until progression per RECIST v1.1 as assessed by the Investigator at local site, or death due to any cause, regardless of whether the participant withdraws from randomized therapy, receives another anti-cancer therapy or clinically progresses prior to RECIST v1.1 progression.

Duration of Response (DoR)From the date of first documented confirmed response until date of documented progression (approximately 2 years).

The time from the date of first documented confirmed response until date of first documented progression per RECIST v1.1 or death due to any cause.

Disease control rate (DCR)Up to 11 weeks post date of first dose/randomisation

The percentage of participants who have a confirmed CR or PR or who have SD per RECIST v1.1 as assessed by the Investigator at local site and derived from the raw tumour data up to 11 weeks after date of first dose/randomisation.

Percentage change in tumor sizeFrom start through to study completion.

The best percentage change from baseline in tumor size is the largest decrease (or smallest increase) from baseline for a participant, using RECIST v1.1 assessments.

Serum concentration of AZD0901 (total ADC), total antibody (conjugated and unconjugated) and total unconjugated MMAEFrom date of first dose of AZD0901 up until 90 days post AZD0901 discontinuation.

To characterise the PK of AZD0901 monotherapy or in combination with anti cancer agents in participants with advanced or metastatic solid tumours expressing CLDN18.2.

Serum PK parameters of AZD0901, total antibody (conjugated and unconjugated) and MMAE including but not limited to AUC, Cmax, tmax, clearance and half-life, as data allow.From date of first dose of AZD0901 up until 90 days post AZD0901 discontinuation.

To characterise the PK of AZD0901 monotherapy or in combination with anti cancer agents in participants with advanced or metastatic solid tumours expressing CLDN18.2.

Clinical activity by baseline and/or on-treatment tissue-based biomarkers including, but not limited to, gene expression, mutation profiles, DNA damage, protein expression, immune response and/or mechanisms of resistance.From date of first dose of AZD0901 up to 7 weeks.

To investigate baseline and/or on-treatment tissue-based RNA, DNA, and/or proteins, and association with clinical activity of AZD0901 (substudy 1).

ADA status will be determined along with prevalence and incidence of anti-drug antibodies to AZD0901, and titer established.From date of first dose of AZD0901 up until 90 days post AZD0901 discontinuation.

To determine the immunogenicity of AZD0901 monotherapy or in combination with anti-cancer agents in participants with advanced or metastatic solid tumours expressing CLDN18.2.
