Study Endpoints

Primary Endpoints

The mass balance of total Radioactivity of AZD1390 and its metabolites after a single oral dose
6 Weeks

Amount excreted (Ae) (urine)

Pharmacokinetic(s) of AZD1390 and the distribution of total radioactivity into blood cells after a single oral dose
6 weeks

Analysis of plasma: Maximum observed concentration (Cmax)

Pharmacokinetic(s) of AZD1390 after a single oral dose
6 weeks

Analysis of urine: Cumulative amount excreted (CumAe)

The distribution of total radioactivity into blood cells after a single oral dose
6 weeks

Analysis of urine: Fraction (percentage) excreted (Fe)

Incidence of dose-limiting toxicities (DLTs)
From the start of treatment until the end of the DLT period (approximately 6 weeks for Arm A, 3 weeks for Arm B and 10 weeks for Arm C)

DLTs will be used to calculate the maximum tolerated dose (MTD). In each arm, the MTD of AZD1390 is the highest dose at which the predicted probability of a DLT is less than 25% in that specific RT setting

Incidence of adverse events (AEs) and serious adverse events (SAEs)
From the start of treatment until the end of the study (approximately 9 months after the last patient has started treatment)

For each adverse event CTCAE grade and causality (related to AZD1390 or radiotherapy) will be collected.

Frequently asked questions about AZD1390

What is AZD1390?

AZD1390 is an investigational small molecule developed by AstraZeneca PLC (ticker AZN) as an oncology drug. It is being studied in advanced solid malignancies and recurrent glioblastoma multiforme, and it is designed to be given in combination with radiation therapy in patients with brain cancer.

What does AZD1390 target?

AZD1390 targets ATM, the ataxia telangiectasia mutated kinase. By acting on ATM, the small molecule is being developed for use alongside radiation therapy in brain cancer and in advanced solid malignancies, where the combination is under study for safety and tolerability.

Who makes AZD1390?

AstraZeneca PLC, which trades under the ticker AZN, is the developer of AZD1390. The company is running the clinical program for the drug in oncology, including a Phase 1 study of AZD1390 given with radiation therapy in patients with brain cancer.

What phase is AZD1390 in?

AZD1390 is in Phase 1 clinical development. It is investigational and is being evaluated in early-stage trials, including a completed Phase 1 study of AZD1390 with radiation therapy in brain cancer and a Phase 1 human ADME study in advanced solid malignancies.

What clinical trials is AZD1390 in?

AZD1390 has been studied in NCT03423628, a completed Phase 1 trial of AZD1390 with radiation therapy in patients with brain cancer that enrolled 159 participants across the United States, Japan, and the United Kingdom. A Phase 1 human ADME study, NCT07643870, is also registered in advanced solid malignancies in the United Kingdom.

Is AZD1390 the same as [11C]AZD1390?

Yes, [11C]AZD1390 is another name for AZD1390. The carbon-11 label refers to a radiolabeled form used in study settings, and searches for either name refer to the same AstraZeneca investigational ATM-targeting small molecule in Phase 1 development for oncology indications.
