Clinical Trial Summary

This is a Phase 2, multicenter, randomized, open-label study evaluating the safety and efficacy of trilaciclib administered with platinum-based chemotherapy followed by trilaciclib administered with avelumab maintenance therapy compared with platinum-based chemotherapy followed by avelumab maintenance therapy in patients receiving first-line treatment for advanced/metastatic bladder cancer.

Description:

Patients will be randomly assigned (1:1) to receive standard of care platinum-based chemotherapy (with or without the addition of trilaciclib) administered intravenously (IV) in 21-day cycles followed by standard of care avelumab maintenance therapy (with or without the addition of trilaciclib) administered IV in 14-day cycles.

Patients enrolled in the study will be eligible to receive 4-6 cycles of platinum-based chemotherapy, and patients without progressive disease (PD) as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 guidelines (i.e., with an ongoing complete response [CR], partial response [PR], or stable disease) after platinum-based chemotherapy will be eligible to receive avelumab maintenance therapy until disease progression, unacceptable toxicity, withdrawal of consent, Investigator decision, or the end of the trial, whichever comes first.

Patients will be followed for survival approximately every 3 months after receiving the last dose of study medication.

2. Malignancies other than urothelial carcinoma within 3 years prior to randomization, except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the breast or of the cervix, or low-grade (Gleason =6) prostate cancer on surveillance without any plans for treatment intervention (e.g., surgery, radiation, or castration)

3. Presence of central nervous system (CNS) metastases/leptomeningeal disease requiring immediate treatment with radiation therapy or steroids.

4. QTcF interval > 480 msec. For patients with ventricular pacemakers, QTcF > 500 msec

5. Known hypersensitivity or allergy to avelumab, gemcitabine, cisplatin or carboplatin

6. Known severe hypersensitivity reactions to monoclonal antibodies (Grade =3), any history of anaphylaxis, or uncontrolled asthma

7. Prior hematopoietic stem cell or bone marrow transplantation, or solid organ transplantation

8. Pregnant or lactating women

9. Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent

10. Current use of immunosuppressive medication, EXCEPT for the following:

1. Intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection)

2. Systemic corticosteroids at physiological doses =10 mg/day of prednisone or equivalent

3. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)

Secondary	Anti-tumor Effects	To evaluate the effect of trilaciclib on overall survival (OS) when administered with platinum-based chemotherapy followed by trilaciclib administered with avelumab maintenance therapy compared with platinum-based chemotherapy followed by avelumab maintenance therapy alone.
