Study of AZD0466 Monotherapy or in Combination in Patients With Advanced Haematological Malignancies


About this study

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

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

electrocardiogram (ECGs), in the absence of a cardiac pacemaker; abnormalities in
rhythm, conduction or morphology of resting ECG; any factors that increase the risk of
QTc prolongation or risk of arrhythmic events such 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. The following are permitted: myelodysplastic syndrome or myeloproliferative
neoplasm (including chronic myelomonocytic leukaemia [CMML]); 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; 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; chemotherapy within ≤14 days or 5 half-lives prior to the first
dose of study treatment. Treatment with high-dose steroids for primary malignancy
control is permitted but must be discontinued at least 2 days prior to the first dose
of study treatment. Treatment with hydroxyurea is permitted; immunotherapies and
cellular therapies within 4 weeks prior to the first dose of study treatment;
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 prior to 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 of the specific drug 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 and heparin, which
