Summary

The goal of this clinical research is to find if sequential therapy with combined androgen deprivation or hormonal therapy with luteinizing hormone release hormone (LHRH) analog plus a new hormonal agent (abiraterone, enzalutamide, or apalutamide) followed by chemohormonal therapy with docetaxel and LHRH analog would improve the outcome of high risk metastatic/stage IV prostate cancer.

Eligibility

Yes No Not Sure

Inclusion Criteria

Biopsy proven prostate cancer and the diagnosis can be established through either prostate biopsy or biopsy of a metastatic lesion. High risk mCSPC is defined as having 2 of the 3 risk factors: a Gleason score of 8 or more, at least 3 bone metastases, and the presence of measurable visceral metastasis
ECOG performance status of 0-1
No androgen deprivation therapy (ADT) with LHRH analogue monotherapy for more than 12 weeks after the diagnosis of metastatic prostate cancer. Prior ADT in the non-metastatic setting is allowed if it was given > 2 years prior to the diagnosis of metastatic prostate cancer and a reduction of PSA is documented after initiating ADT in the metastatic setting
Agreeable to prostate biopsy after completing "second strike
Adequate organ function with absolute neutrophil count > 1000/l, Hb > 10 g/dl, Platelet > 100,000/l, Creatinine and liver enzymes within 1.5 folds of upper limits of normal
No uncontrolled arrhythmia; participants with h/o myocardial infarction or history of congestive heart failure, need to have estimated left ventricle ejection fraction above 40% either on echocardiogram or MUGA scan within 6 months of study enrollment
All men who are sexually active with a female partner of childbearing potential treated or enrolled on this protocol must agree to use highly effective barrier contraception prior to the study, for the duration of study participation, and for 7 months after last dose of tislelizumab administration
Ability to understand and the willingness to sign a written informed consent document or have a legally authorized representative sign on the participants behalf. Stated willingness to comply with all study procedures and availability for the duration of the study
\- Inclusion of minorities: Men of all races and ethnic groups who met the above inclusion criteria are eligible for this trial

Exclusion Criteria

Prior treatments with TAK-700/Orteronel, abiraterone, darolutamide, apalutamide or enzalutamide for more than eight weeks
Any previous treatment with a PD-1 or PD-L1 inhibitor
Documented brain metastases
Prior prostatectomy
History of allergic reactions attributed to compounds of similar chemical or biologic composition to docetaxel (including any drugs formulated with polysorbate 80), or LHRH analogue (e.g., leuprolide, triptorelin, goserelin acetate, degarelix)
Treatment with any investigational compound within 30 days prior to the first dose of study drugs
Diagnosis or treatment for another systemic malignancy within 2 years before the first dose of study drugs, or previously diagnosed with another malignancy & have any evidence of residual disease. Participants with non-melanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Participants with delayed healing of wounds, ulcers, and/or bone fractures
Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome. HIV-positive participants on combination antiretroviral therapy are ineligible because of the potential for tislelizumab to be less clinically active in this population
Active or prior documented autoimmune or inflammatory disorders, including inflammatory bowel disease (e.g., Crohn's disease), systemic lupus erythematosus, Sarcoidosis syndrome, Grave's disease, rheumatoid arthritis, hypophysitis, uveitis, with the following exceptions: • Vitiligo or alopecia • Hypothyroidism stable on hormone replacement • Chronic skin condition that does not require systemic therapy • Celiac disease controlled by diet alone • Participants with inactive disease in the last 5 years may be included
Active infection including tuberculosis, hepatitis B (known positive HBV surface antigen [HBsAg]), or hepatitis C (HCV). Participants with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Participants with positive HCV antibody are eligible if polymerase chain reaction is negative for HCV RNA
Concurrent or prior use of immunosuppressive medication within 14 days before the first dose of study chemoimmunotherapy, with the following exceptions: premedication for docetaxel with 8 mg oral dexamethasone approximately 12 hr, 8 hr and 1 hr prior to each docetaxel administration; intranasal, inhaled, topical steroids, or local steroid injections (e.g., intraarticular injection); systemic corticosteroids at physiologic doses not exceeding 10mg/day of prednisone or its equivalent; steroids as premedication for hypersensitivity reactions (e.g., premedication for iodinated contrast allergy before CT scan)
History of severe hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins
History of interstitial lung disease, non-infectious pneumonitis or uncontrolled diseases including pulmonary fibrosis, acute lung diseases, etc
Was administered a live vaccine ≤ 4 weeks before first dose of tislelizumab NOTE:Seasonal vaccines for influenza and COVID-19 vaccines are generally inactivated vaccines and are allowed. Intranasal vaccines are live vaccines and are not allowed
Inability to comply with protocol requirements
Inclusion of minorities: Men of all races and ethnic groups who met the above exclusion criteria are eligible for this trial
