Summary

The purpose of the study is to the evaluate safety, tolerability, pharmacokinetics (PK), and efficacy of AZD0466 as monotherapy in partciapants with advanced haematological malignancies and also to assess drug-drug interaction (DDI) potential between AZD0466 and the azole antifungal voriconazole.

Description

The study consists of 2 individual modules as: Module 1 (AZD0466 monotherapy), and Module 2 (DDI study of AZD0466 with voriconazole).

Eligible participants will be assigned to study treatments across Modules 1 and 2.

  1. Module 1: AZD0466 monotherapy will include 2 parts- Part A dose escalation cohorts and Part B dose expansion cohorts. Initiation of Part B will depend on the evaluation of safety, tolerability, and PK in Part A.
  2. Module 2: AZD0466 and voriconazole DDI study.

All participants will receive AZD0466, and administration will continue until disease progression, initiation of alternative anticancer therapy, unacceptable toxicity, withdrawal of consent, or other reasons to discontinue study treatment.

Eastern cooperative oncology group performance status 2. Performance status must not have deteriorated by 2 levels within 2 weeks after providing informed consent
Predicted life expectancy 12 weeks
Adequate organ function at screening as per the protocol defined criteria
Adequate cardiac function as demonstrated by LVEF > 50% on screening cardiac multigated acquisition, magnetic resonance image or echocardiogram
Willing and able to participate in all required study evaluations and procedures including receiving IV administration of study treatment and admission to the hospital, when required, for administration of study treatment and monitoring

Active graft versus host disease
Active central nervous system (CNS) leukaemia/leptomeningeal disease/spinal cord compression. Participants who have a history of CNS leukaemia must be free of CNS leukaemia for >30 days prior to the first dose of study treatment, and the most recent 2 lumbar punctures must be negative for leukaemic cells, to be eligible
Active cytomegalovirus (CMV) infection (positive CMV Immunoglobulin M (IgM) and/or positive polymerase chain reaction (PCR) result)
Active infection including human immunodeficiency virus, Hepatitis B, Hepatitis C, or severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2)
As judged by the Investigator: any evidence of severe or uncontrolled systemic diseases, (eg, severe hepatic impairment, interstitial lung disease [bilateral, diffuse, parenchymal lung disease]); current unstable or uncompensated respiratory or cardiac conditions; Uncontrolled hypertension; history of, or active, bleeding diatheses (eg, haemophilia or von Willebrand disease); uncontrolled active systemic fungal, bacterial, or other infection
Any of the given cardiac criteria: history of cardiomyopathy, myocarditis or heart failure; mean resting corrected QT interval (QTcF) 470 msec obtained from 3 electrocardiogram (ECGs), in the absence of a cardiac pacemaker; any clinically important abnormalities in rhythm, conduction or morphology of resting ECG; any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalaemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age
History of another life-threatening malignancy 2 years prior to first dose of study treatment with the exception of: malignancy treated with curative intent and with no evidence of active disease present for more than 2 years before screening and considered to be at low risk of recurrence by the treating physician; adequately treated lentigo malignant melanoma without current evidence of disease or adequately controlled non-melanomatous skin cancer; adequately treated carcinoma in situ without current evidence of disease
Any of the mentioned procedures or conditions currently or in the 6 months prior to the first dose of study treatment: coronary artery bypass graft; angioplasty; vascular stent; myocardial infarction; angina pectoris; congestive heart failure (New York Heart Association Class 2); ventricular arrhythmias requiring continuous therapy; ventricular arrhythmias requiring continuous therapy; haemorrhagic or thrombotic stroke, including transient ischaemic attacks or any other CNS bleeding
Treatment with any of the mentioned therapy: radiotherapy less than 3 weeks prior to first study treatment; immunotherapy or chemotherapy within 21 days or 5 half-lives prior to the first dose of study treatment. Treatment with one dose of cytarabine, steroids, or 6-mercaptopurine is permitted prior to the first dose of study treatment but these should be discontinued at least 2 days prior to the first dose of study treatment. Treatment with hydroxyurea is permitted as previously outlined; investigational drugs within 14 days or 5 half-lives (whichever is shorter) prior to the first dose of study treatment; major surgery (excluding placement of vascular access) 21 days, or minor surgical procedures 7 days, prior to the first dose of study treatment. No waiting is required mentioned implantable port or catheter placement; prescription or non-prescription drugs or other products known to be sensitive substrates of BCRP, OCT2, OAT3, OATP1B1, OATP1B3, CYP2B6, CYP2C8, CYP2C9 or CYP2D6, or reversible moderate or strong CYP3A inhibitors, which cannot be discontinued within 5 half-lives of the first dose of study treatment and withheld throughout the study until 14 days after the last dose of AZD0466; moderate or strong mechanism-based inhibitors or inducers of CYP3A4 which cannot be discontinued within 5 half-lives plus 12 days of the drug prior to the first dose of study treatment and withheld until 14 days after the last dose of AZD0466; concurrent anti-coagulation therapy, including aspirin, which cannot be stopped; medications with known risk of Torsades de Pointes within 5 half-lives of the first dose of study treatment and continuing until 5 half-lives after the last dose of AZD0466; IV anti infection treatment within 14 days before first dose of study treatment
