Locally Advanced or Metastatic Solid Tumours | Drug: AZD0171 Drug: Durvalumab Drug: Gemcitabine Drug: Nab-paclitaxel | Phase 2 |
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 PK profile of AZD0171, durvalumab and chemotherapy - Area under the concentration-time curve (AUC) [ Time Frame: At predefined intervals from first dose of study intervention up to Day 90 post last dose of study intervention on Day 15 ]The PK profile of AZD0171, durvalumab and chemotherapies and/or their metabolites will be determined.
- The PK profile of AZD0171, durvalumab and chemotherapy - Clearance (CL) [ Time Frame: At predefined intervals from first dose of study intervention up to Day 90 post last dose of study intervention on Day 15 ]The PK profile of AZD0171, durvalumab and chemotherapies and/or their metabolites will be determined.
- The PK profile of AZD0171, durvalumab and chemotherapy - Terminal elimination half-life (t1/2) [ Time Frame: At predefined intervals from first dose of study intervention up to Day 90 post last dose of study intervention on Day 15 ]The PK profile of AZD0171, durvalumab and chemotherapies and/or their metabolites will be determined.
- Participants with changes from Baseline in cluster of differentiation 8 (CD8+) T cell tumour infiltration in tumour samples [ Time Frame: Up to 24 months ]The changes in CD8+ T cell tumour infiltration associated with AZD0171 treatment in combination with durvalumab and chemotherapy will be assessed in participants with 1L mPDAC.
- Change from baseline in leukaemia inhibitory factor (LIF) bound to AZD0171 (total LIF) [ Time Frame: At predefined intervals from first dose of study intervention up to Cycle 11 (each cycle is 28 days in length) ]The absolute values and the change from baseline in LIF bound to AZD0171 (total LIF) will be assessed.
