All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  • Signed Informed Consent Form (ICF)

  • Age ≥ 18 years at time of signing ICF

  • Ability to comply with the study protocol, in the investigator's judgment

  • Histologically or cytologically confirmed advanced non-squamous NSCLC that is not amenable to definitive therapy

  • Tumor PD-L1 expression (TPS ≥ 1%) (cohort A only)

  • EGFR, ALK, ROS1 wild-type (cohort A only)

  • Confirmed activating alteration in EGFR (cohort B only)

  • Disease progression during or following treatment with anti-PD(L)1 containing therapy (cohort A only)

  • Disease progression during or following treatment with appropriate EGFR TKI therapy (cohort B only)

  • Measurable disease per RECIST v1.1

  • Biopsy post-progression on anti-PD(L)1 (cohort A) or EGFR TKI therapy (cohort B) confirming non-squamous histology prior to study treatment initiation

  • ECOG Performance Status of 0-2

  • Adequate hematologic and end-organ function, defined by the following laboratory test results, obtained within 14 days prior to initiation of study treatment:

  • ANC ≥ 1.0 x 10^9/L without granulocyte colony-stimulating factor support

  • Lymphocyte count ≥ 0.5 x 10^9/L

  • Platelet count ≥ 100 x 10^9/L without transfusion

  • Hemoglobin ≥ 80 g/L (8 g/dL) - patients may be transfused to meet this criterion.

  • AST, ALT, and alkaline phosphatase (ALP) ≤ 2.5 x upper limit of normal (ULN), with the following exceptions: Patients with documented liver metastases: AST and ALT ≤ 5 x ULN; Patients with documented liver or bone metastases: ALP ≤ 5 x ULN

  • Serum bilirubin ≤ 1.5 x ULN with the following exception: Patients with known Gilbert disease: serum bilirubin ≤ 3 x ULN

  • Creatinine clearance ≥ 30 mL/min (calculated using the Cockcroft-Gault formula)

  • For patients not receiving therapeutic anticoagulation: INR and aPTT ≤ 1.5 x ULN

  • For patients receiving therapeutic anticoagulation: stable anticoagulant regimen defined as clinical stability on unchanged dose of therapeutic anticoagulation for ≥14 days

  • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods, and agreement to refrain from donating eggs, as defined below:

  • Women must remain abstinent or use contraceptive methods with a failure rate of < 1% per year during the treatment period and for 6 months after the final dose of study treatment. Women must refrain from donating eggs during this same period.

  • A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). The definition of childbearing potential may be adapted for alignment with local guidelines or requirements.

  • Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.

  • The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post-ovulation methods) and withdrawal are not adequate methods of contraception.

  • For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below:

  • With a female partner of childbearing potential who is not pregnant, men who are not surgically sterile must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for 6 months after the final dose of bevacizumab and 90 days after the final dose of tiragolumab. Men must refrain from donating sperm during this this same period.

  • With a pregnant female partner, men must remain abstinent or use a condom during the treatment period and for 6 months after the final dose of bevacizumab and 90 days after the final dose of tiragolumab to avoid potential exposure to the embryo.

  • The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post-ovulation methods) and withdrawal are not adequate methods of contraception.
