Inclusion Criteria

Male or female subjects = 18 years old., Patients with adequate normal organ and marrow function assessed within 14 days prior to start of the study treatment as defined below: a) Hemoglobin = 9.0 g/dL (Patients may be transfused to meet this criterion). b) Absolute neutrophil count (ANC) =1500 per mm 3 . c) Platelet count = 100,000 per mm 3 . d) Serum total bilirubin = 1.5 X institutional upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert’s syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of haemolysis or hepatic pathology); however, they will be allowed only in consultation with their physician if total bilirubin = 3 × ULN. e) Serum transaminases (ALT, AST and ALP) = 2.5X ULN. f) Serum albumin = 25 g/L (2.5 g/dL). g) Creatinine = 1.5 mg/dL or measured creatinine clearance (CL) > 60 mL/min or Calculated creatinine CL > 60 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for the determination of creatinine clearance., Absence of active infection that requires systemic antibiotics., Female subjects of childbearing potential (WOCBP) must provide a negative urine pregnancy test at screening, and must agree to use medically accepted and highly effective birth control methods for the duration of the study treatment and for 90 days after the final dose of tiragolumab, 5 months after the final dose of atezolizumab, and 6 months after the final dose of cisplatin / 5 FU. ? A woman is considered of childbearing potential ( i.e. fertile) following menarche and until becoming post-menopausal unless permanently sterile. Women will be considered post-menopausal if they have been amenorrhoeic for 12 months without an alternative medical cause. The following age-specific requirements apply: a) Amenorrheic for =1 year in the absence of chemotherapy and/or hormonal treatments b) Luteinizing hormone (LH) and/or follicle stimulating hormone and/or estradiol levels in the post-menopausal range c) Radiation induced oophorectomy with last menses >1 year ago d) Chemotherapy induced menopause with >1 year interval since last menses e) Surgical sterilization (bilateral oophorectomy or hysterectomy) f) Women <50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy) g) Women =50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy)., For both male and female patients/partners: Contraceptive use should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. Non-sterile males must be willing to use a condom plus an additional highly effective contraceptive of birth control for the duration of the study treatment and for 90 days after the final dose of tiragolumab, and 6 months after the final dose of cisplatin / 5-FU. ? A sterile male is defined as: a) One for whom azoospermia has been previously demonstrated in a semen sample examination as definitive evidence of in

Exclusion Criteria

(c) Receiving antiretroviral therapy (ART/HAART) for at least 4 weeks prior to study enrollment, and having not experienced any HIV-related opportunistic infection for at least 4 weeks prior to study enrollment., Treatment with therapeutic oral or IV antibiotics within 2 weeks prior to initiation of study treatment.

Fertile and sexually active patients who are not willing to use the appropriate highly effective contraceptive methods., Any underlying medical or psychiatric disorder, which, in the opinion of the investigator, makes the administration of atezolizumab or tiragolumab unsafe or interferes with the informed consent process or trial procedures., Prior treatment for the control of the squamous cell carcinoma of the anal canal. Prior radiotherapy, chemotherapy or treatment with CD137 agonists or immune checkpoint blockade therapies, anti-CTLA-4, anti-TIGIT, anti-PD-1, and anti-PD-L1 therapeutic antibodies are not allowed., History of severe allergic anaphylactic reactions to chimeric or humanized antibodies or fusion proteins.
