A Clinical Trial to Evaluate AZD7648 Alone and in Combination With Other Anti-cancer Agents in Patients With Advanced Cancers.

Inclusion Criteria

• Capable and willing to give signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF).
• Participant must be at least 18 years of age, at the time of signing the ICF.
• Participants must have histological or cytological confirmation of advanced malignancy considered to be suitable for study treatment.
• Eastern cooperative oncology group performance status 0-1.
• Life expectancy greater than 12 weeks.
• Progressive cancer at the time of study entry.
• Pharmacodynamics expansion cohorts: Participants must have at least 1 tumour suitable for biopsy and consent to having biopsies collected.
• Negative pregnancy test (urine or serum) prior to start of dosing for women of childbearing potential.
• Female participants must be post-menopausal, surgically sterile, or using an acceptable method of contraception for the duration of the study (from the time they sign consent) and for 12 weeks after the last dose of study treatment to prevent pregnancy.
• For the duration of the study (from the time they sign consent) and for 12 weeks after the last dose of study treatment, sexually active male participants must be willing to use contraception.

Post-menopausal is defined as:

• No menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the post-menopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy). However in the absence of 12 months of amenorrhea, a FSH measurement is insufficient.
• Radiation-induced oophorectomy with last menses greater than 12 months ago.
• Chemotherapy-induced menopause with greater than 12 month interval since last menses.
• Surgical sterilisation.

Exclusion Criteria

• Any unresolved toxicities from prior therapy common terminology criteria for adverse event (CTCAE) Grade ≥2 (with the exception of alopecia).

• As judged by the Investigator, any evidence of severe or uncontrolled medical conditions including but not limited to:
• Uncontrolled diabetes mellitus, uncontrolled seizures, active infection requiring systemic antibiotics, antifungal or antiviral drugs, severe chronic obstructive pulmonary disease, severe Parkinson's disease, active inflammatory bowel disease, psychiatric condition, active bleeding diatheses, renal transplant, or active infection including any participant with active hepatitis B, hepatitis C or human immunodeficiency virus.
• Any other malignancy which has been active or treated within the past 3 years, with the exception of in situ cancer of the cervix, non-melanoma skin cancer, ductal carcinoma in situ, Stage 1 Grade 1 endometrial carcinoma, or other solid tumours including lymphomas curatively treated with no evidence of disease for ≥5 years.
• Refractory nausea and vomiting or unable to swallow and retain oral medication, chronic gastrointestinal diseases or previous bowel resection with clinically significant sequelae that would preclude adequate absorption of AZD7648, gastrointestinal symptoms CTCAE Grade >1, history of gastrointestinal ulceration and gastrointestinal haemorrhage within 6 months of first study drug administration.
