A Study of AZD3470, a PRMT5 Inhibitor, in Patients With MTAP Deficient Advanced/Metastatic Solid Tumors
PRIMROSE
PRIMROSE: A Modular Phase I/IIa, Multi-centre, Dose Escalation, and Expansion Study of AZD3470, a MTA Cooperative PRMT5 Inhibitor, as Monotherapy and in Combination With Anticancer Agents in Patients With Advanced/Metastatic Solid Tumors That Are MTAP Deficient

Brief Summary
This is a first time in human (FTiH) Phase I/IIa, open-label, multi-centre study of AZD3470 in participants with advanced or metastatic solid tumors with MTAP deficiency. The study consists of several study modules, evaluating the safety, tolerability, pharmacokinetic (PK), pharmacodynamics, and preliminary efficacy of AZD3470 as monotherapy or in combination with other anti-cancer agents.

Outcome Measures
Primary Outcomes (2)
Incidence of adverse events (AEs) and serious adverse events (SAEs)
Number of participants with AEs and SAEs
From time of informed consent to 28 days post last dose of AZD3470
Incidence of dose-limiting toxicities (DLT)
Incidence of dose-limiting toxicities (DLT) as determined by number of patients with at least 1 dose-limiting toxicity (DLT). DLT is defined as an AE (adverse event) or abnormal laboratory value that occurs during the DLT period (defined as 21 days after start of study intervention) that is assessed as unrelated to the disease, intercurrent illness, or concomitant medications and meets any DLT criteria defined in the clinical study protocol
From first dose of study treatment until the end of Cycle 1 (each cycle is 21 days)
Secondary Outcomes (16)
Radiological response assessed by the Investigator evaluated according to RECIST v1.1 - ORR (Objective Response Rate)
From date of first dose of AZD3470 up until progression, or the last evaluable assessment in the absence of progression (approximately 2 years).
Radiological response assessed by the Investigator evaluated according to RECIST v1.1 - DoR (Duration of Response)
From date of first dose of AZD3470 up until progression, or the last evaluable assessment in the absence of progression (approximately 2 years).
Radiological response assessed by the Investigator evaluated according to RECIST v1.1 - Best percentage change in tumor size
From date of first dose of AZD3470 up until progression, or the last evaluable assessment in the absence of progression (approximately 2 years).
Radiological response assessed by the Investigator evaluated according to RECIST v1.1 - PFS (Progression Free Survival)
From date of first dose of AZD3470 up until progression, or the last evaluable assessment in the absence of progression (approximately 2 years).
Radiological response assessed by the Investigator evaluated according to RECIST v1.1 - DCR (Disease Control Rate) at 12 weeks
From date of first dose of AZD3470 up until progression, or the last evaluable assessment in the absence of progression (for each patient this is expected to be measured at 12 weeks).

EXPERIMENTALPart A dose escalation and back-fill cohorts and Part B dose optimization and expansion cohorts of varying doses of AZD3470
Interventions
AZD3470 is a novel, potent and selective, second-generation, MTAP-selective, inhibitor of PRMT5.
Eligibility Criteria
You may qualify if:
- Participant must be at least 18 years of age or the legal age of consent in the jurisdiction in which the study is taking place, at the time of signing the ICF.
- Willing to provide archival and/or baseline tumor sample to meet the minimum tissue requirement for central MTAP deficiency testing.
- Participants must have received and progressed, are refractory or are intolerant to standard therapy for the specific tumor type. All participants are required to have had at least one prior line of treatment in the recurrent or metastatic setting.
- MTAP deficient tumors defined as evidence of homozygous deletion of one or more exons of the MTAP gene in tumor tissue AND/OR loss of MTAP expression in the tumor tissue.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1
- A minimum life expectance of 12 weeks in the opinion of the Investigator.
- Participants must have at least one measurable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
- Adequate organ and bone marrow reserve function.
- Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
You may not qualify if:
- Spinal cord compression or symptomatic and unstable brain metastases or leptomeningeal disease or primary malignancies of the central nervous system.
- Allogeneic organ transplantation.
- Any significant laboratory finding or any severe and uncontrolled medical condition.
- Any of the following cardiac criteria:
- LVEF ≤ 50%
- prior or current cardiomyopathy
- clinically active cardiovascular disease, or a history of myocardial infarction within the last 6 months
- uncontrolled angina or acute coronary syndrome within 6 months
- severe valvular heart disease
- uncontrolled hypertension
- risk of brain perfusion problems. Stroke or transient ischemic attack in the last 6 months, undergone coronary artery bypass graft, angioplasty or vascular stent
