A Phase 1 interventional study of AZD4635 and Durvalumab in Advanced Solid Malignancies, Non-Small Cell Lung Cancer (NSCLC) and Metastatic Castrate-Resistant Prostate Carcinoma (mCRPC), sponsored by AstraZeneca. Completed at 17 sites in United States. Open to participants aged 18 Years to 130 Years. Per ClinicalTrials.gov, last updated 2023-05-26.
Sponsored by AstraZeneca · Phase 1, Interventional, and Treatment
This is a Phase 1, open-label, multicenter study of continuous oral dosing of AZD4635 administered to patients with advanced solid malignancies. Dosing will be escalated until a maximum-tolerated dose (MTD) is determined in patients. The MTD will be defined by dose-limiting toxicity. The study design allows an escalation of dose with intensive safety monitoring to ensure the safety of the patients. Expansion cohorts will further assess safety and preliminary anti-tumor activity in a variety of advanced solid tumor malignancies. Other dosing schedules and/or combinations may be evaluated based on the emerging PK and safety data.
The primary objectives of this study are to:
The study will be conducted in two segments. The first segment of the study, designated Phase 1a, will be a dose escalation design in order to assess the safety, tolerability, pharmacokinetics (PK), and preliminary anti-tumor activity of ascending doses of AZD4635 as monotherapy, in combination with durvalumab or durvalumab plus oleclumab, in combination with docetaxel, and in combination with either abiraterone acetate or with enzalutamide.
A capsule formulation of AZD4635 will be evaluated in 3 arms (arms CA, CB, and CC). An oral nanoparticle suspension in water constituted extemporaneously by the patient will be administered in all other treatment arms. Most patients who started therapy with the nanoparticle suspension will transition to the capsule dosage form depending on the arm they are assigned to and emerging data. Active patients in arms C, D, E, F, G, H, I, J, K, KD, and L should be offered the option to transition to the capsule formulation at the discretion of the Investigator in discussion with the Medical Monitor. Patients in study arms AA and AE receiving AZD4635 as the nanoparticle suspension should change over to the capsule formulation as soon as possible at the discretion of the Investigator.
The dose escalation arms are described as follows:
Arms A through E enrolled 38 patients in Phase 1a in order to establish the Recommended Phase 2 Dose (RP2D) of the nanoparticle suspension formulation of AZD4635 as a single agent or in combination with durvalumab.
● Arms EA and AA. Arms EA and AA [dose escalation of AZD4635 in combination with either abiraterone acetate plus prednisone or enzalutamide in patients with metastatic castrate-resistant prostate cancer (mRCPC)]. The AZD4635 plus hormonal therapy cohorts will enroll concurrently. Patients who previously received abiraterone acetate, enzalutamide, or apalutamide as part of their prior treatments for mCRPC may be enrolled to the enzalutamide plus AZD4635 arm (Cohort EA) or the abiraterone acetate plus AZD4635 arm (Cohort AA) at the discretion of the Investigator. Approximately 24 to 48 patients with mCRPC will be treated in the AZD4635 plus hormonal therapy arms in order to establish the RP2D.
In Phase 1a approximately 90-132 patients will be treated with AZD4635 as a single agent or in combination with durvalumab, durvalumab plus oleclumab, docetaxel, abiraterone acetate or enzalutamide.
The second segment of the study, designated Phase 1b, will further assess the safety and preliminary activity in the expansion arms described below.
Patients will be randomly assigned between open-label arms with AZD4635 monotherapy and AZD4635 combined with durvalumab in NSCLC (Arms F/G) and mCRPC (Arms I/J) in order to minimize bias.
Patients with CRC, excluding MSI high, will be enrolled to AZD4635 monotherapy (Arm K) and AZD4635 combined with durvalumab (Arm KD) in patients with CRC.
Some arms will have a mandatory biopsy subgroup to ensure sufficient tissue is collected to assess the mechanism of action in tissue without excluding patients with nonbiopsiable disease. Biopsies are optional in all other arms.

The incidence of Dose-Limiting Toxicities (DLTs) in patients receiving AZD4635 monotherapy orally.
A Bayesian Logistic Regression Model (BLRM) based approach will be used to identify the set of AZD4635 doses where the incidence of DLTs is no larger than 33%. In each arm, up to 3 patients will be initially assessed. The dose will be escalated to the next higher dose level if all 3 patients in the previous dose level complete the DLT evaluation period without a DLT. Following the first DLT, the BLRM model will be run and the output made available to the safety review committee (SRC) to guide further dosing decisions. Each dose cohort will include a maximum of 6 patients.

Tumour Response
Categorization of objective tumour response assessment will be based on the RECIST Version 1.1 guidelines for response (CR (complete response), PR (partial response), SD (stable disease), and PD (progressive disease). For patients who only have non-measurable disease at baseline, categorization of objective tumour response assessment will be based on the RECIST Version 1.1 guideline for response for non-target lesions (NTLs): CR, PD, and Non CR/Non PD.
Time frame: Tumour response will be assessed 6 weeks after the start of treatment and then every 8 weeks; after 18 months, assessments will be every 12 weeks.
Progression free survival
Progression free survival is defined as the time interval from the first dose of AZD4635 until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the patient withdraws from study treatment. Subjects who have not progressed or died at the time of analysis will be censored at the time of the last evaluable RECIST assessment.
Time frame: Patients will be restaged after 6 weeks (+/- 7 days) and every 8 weeks (+/- 7 days) thereafter, at the end of treatment visit if required, and at progression free follow up visits if they discontinue study treatment prior to progression.
