Summary

This phase 3 trial compares the addition of nivolumab to chemotherapy (carboplatin and paclitaxel) versus usual treatment (chemotherapy alone) for the treatment of anal cancer that has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab together with carboplatin and paclitaxel may help doctors find out if the treatment is better or the same as the usual approach.

Objectives

PRIMARY OBJECTIVE:
I. To demonstrate that anti-PD-1 therapy in combination with carboplatin/weekly paclitaxel results in improved progression-free survival (PFS) versus systemic chemotherapy alone.

SECONDARY OBJECTIVES:
I. To demonstrate that anti-PD-1 therapy in combination with carboplatin/weekly paclitaxel results in improved overall survival (OS) versus systemic chemotherapy alone.
II. To demonstrate that anti-PD-1 therapy in combination with carboplatin/weekly paclitaxel results in improved objective response using Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 versus systemic chemotherapy alone.
III. To evaluate toxicity profiles of the two regimens.

OUTLINE: Patients are randomized to 1 of 2 arms. Randomization will be 2:1 favoring the experimental regimen, Arm B.

ARM A: Patients receive paclitaxel intravenously (IV) on days 1, 8, and 15 of each cycle, and carboplatin IV on day 1 of each cycle. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive nivolumab IV over 30 minutes on days 1 and 15 of cycle 1 and then on day 1 only of subsequent cycles, paclitaxel IV on days 1, 8, and 15 of each cycle, and carboplatin on day 1 of each cycle. Treatment repeats every 28 days for up to 6 cycles for carboplatin and paclitaxel, and up to 2 years for nivolumab in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 1 month, then every 3 months for 2 years.

Eligibility

  1. Patient must have inoperable, recurrent, or metastatic disease not amenable to curative therapy
  2. Patient must have histological or cytological confirmation of anal squamous cell carcinoma (includes basaloid and cloacogenic lesions) from the primary tumor or a newly diagnosed recurrent/metastatic lesion
  3. Patient must be >= 18 years of age
  4. Patient must have Eastern Cooperative Oncology Group (ECOG) performance status =< 0-1
  5. Patients must have measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria version 1.1 and based on radiologic assessment performed < 4 weeks prior to randomization
  6. Patient receiving palliative (limited-field) radiation therapy is allowed, as long as the lesion treated for palliation is not a target lesion and is > 7 days from completion from palliative radiation
  7. Patients with brain metastasis are eligible if patient is asymptomatic and if treatment ended > 3 months prior to randomization. Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression within 4 weeks prior to randomization
  8. Absolute neutrophil count >= 1,500/mcL (obtained < 14 days prior to randomization)
  9. Platelets >= 100,000/mcL (obtained < 14 days prior to randomization)
  10. Hemoglobin (Hb) >= 9 g/dL for males and >= 9 g/dL for females (obtained < 14 days prior to randomization)
  11. Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (obtained < 14 days prior to randomization)
  12. Aspartate transaminase (AST)(serum glutamic-oxaloacetic transaminase [SGOT]) /alanine transferase (ALT)(serum glutamate pyruvate transaminase [SGPT]) =< 5 x institutional ULN (obtained < 14 days prior to randomization)
  13. Creatinine =< 1.5 x institutional ULN OR creatinine clearance (CrCl) >= 50 mL/min (if using the Cockcroft-Gault formula) (obtained < 14 days prior to randomization)
  14. Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy (ART) with CD4 count >= 200 or have a CD4 count < 200 but an undetectable viral load are eligible * All HIV+ patients should be under the care of an infectious diseases specialist. If a relationship with an infectious diseases specialist is not established, an infectious disease specialist should be consulted. Records of all viral counts and peripheral T-cell counts should be documented in order to follow these values over the course of treatment * All patients must be willing to undergo testing for HIV testing if not tested within the past 12 months
  15. For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable or on suppressive therapy (if indicated)
  16. Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
  17. Patients with known history or current symptoms of cardiac disease, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better. Patients with a history of congestive heart failure (CHF) or who are at risk because of underlying cardiovascular disease or exposure to cardiotoxic drugs must be willing to undergo evaluation of cardiac function including electrocardiogram (EKG) and echocardiogram (ECHO) as clinically indicated
  18. Patient must have the ability to understand and the willingness to sign a written informed consent document. Patients with impaired decision-making capacity (IDMC) who have a legally authorized representative (LAR) or caregiver and/or family member available will also be considered eligible
  19. Patients must agree to not receive live vaccines while on this study

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts... Click here to learn more about clinical trials.
