Inclusion and exclusion criteria

Key Inclusion Criteria:

  • Age ≥ 18 years
  • Relapsed/metastatic solid tumors treated with prior adequate standard of care therapy for tumor type and stage of disease or where in the opinion of the Investigator, a clinical trial is the best option for the next treatment based on response and/or tolerability to prior therapy.
  • Measurable disease per RECIST v1.1
  • Eastern Cooperative Oncology Group (ECOG) Performance Status: 0-1
  • Life expectancy ≥ 12 weeks
  • Adequate organ and marrow function as defined in the protocol

For Sub-Study 1 Part A:

• Histologically or cytologically confirmed metastatic or locally advanced/recurrent breast cancer, ovarian cancer, BTC or endometrial cancer

For Sub-Study 1 Part B:

  • Histologically or cytologically confirmed metastatic or locally advanced and recurrent disease for the respective cohort:

    1. Cohort B1 (Biliary Tract Cancer)

    2. Cohort B2 (Ovarian Cancer)

    3. Cohort B3 (Breast Cancer)

    4. Cohort B4 (Endometrial Cancer)

      For Sub-Study 2 Part A:

  • Minimum body weight ≥ 30 kg.

  • Histologically or cytologically confirmed metastatic or locally advanced/recurrent breast cancer, ovarian cancer, BTC or endometrial cancer.

Exclusion Criteria:

  • Treatment with any of the following:

    1. Nitrosourea or mitomycin C within 6 weeks prior to the first dose of study treatment

    2. Any investigational agents or study drugs from a previous clinical study within 5 half-lives or 28 days (whichever is shorter) prior to the first dose of study treatment

    3. Any other anticancer treatment within the following time periods prior to the first dose of study intervention:

      1. Cytotoxic treatment: 21 days
      2. Non-cytotoxic drugs: 21 days or 5 half-lives (whichever is shorter)
      3. Biological products including immuno-oncology agents: 28 days
  • Spinal cord compression or a history of leptomeningeal carcinomatosis.

  • Brain metastases unless treated, asymptomatic, stable, and not requiring continuous corticosteroids at a dose of > 10 mg prednisone/day or equivalent for at least 4 weeks prior to start of study.

  • Active infection including tuberculosis and HBV, HCV or HIV

  • History of (non-infectious) ILD/pneumonitis that required steroids, has current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening.

  • Clinically severe pulmonary compromise resulting from intercurrent pulmonary illnesses

  • Participants with any of the following cardiac criteria:

    1. History of arrhythmia which is symptomatic or requires treatment (NCI CTCAE v5.0 Grade 3); symptomatic or uncontrolled atrial fibrillation, or asymptomatic sustained ventricular tachycardia.
    2. Uncontrolled hypertension.
    3. Acute coronary syndrome/acute myocardial infarction, unstable angina pectoris, coronary intervention procedure with percutaneous coronary intervention, or coronary artery bypass grafting within 6 months.
    4. History of brain perfusion problems (eg, carotid stenosis) or stroke, or transient ischemic attack in the last 6 months prior to screening.
    5. Symptomatic heart failure (NYHA class ≥ 2).
    6. Prior or current cardiomyopathy.
    7. Severe valvular heart disease.
    8. Mean resting QTcF > 470 msec.
    9. Risk factors for QTc prolongation or risk of arrhythmic events such as heart failure, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age.

Additional Exclusion Criteria for Part A Sub study 2

  1. Thromboembolic event within 3 months before the first dose of study intervention.
  2. Experienced a toxicity that led to permanent discontinuation of prior immunotherapy.
  3. Active or prior documented autoimmune or inflammatory disorders requiring chronic treatment with steroids or other immunosuppressive treatment.

340 participants in 2 patient groups

Sub-Study 1 AZD8205 Monotherapy
Experimental group
Description:
Sub-Study 1 has two parts: Part A : The aim is to determine the safety, tolerability, Recommended Phase 2 Dose(RP2D), and/or the Maximum Tolerated Dose (MTD) of AZD8205. Part B: The aim of dose expansion is to evaluate anti-tumor activity of AZD8205 as monotherapy in select solid tumors.
Treatment:
Drug: AZD8205
Sub Study 2: AZD8205 in combination with rilvegostomig
Experimental group
Description:
Sub-Study 2 has two parts: Part A : Dose escalation to determine the safety, tolerability of AZD8205 + rilvegostomig Part B: Dose expansion to evaluate anti-tumor activity of AZD8205 + rilvegostomig in select solid tumors.
Treatment:
Drug: AZD8205 and AZD2936 (Rilvegostomig)
