Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized phase II trial studies how well cisplatin and fluorouracil work compared with carboplatin and paclitaxel in treating patients with anal cancer that cannot be removed by surgery, has come back at or near the same place as the primary tumor, or spread to other places in the body. Drugs used in chemotherapy, such as cisplatin, fluorouracil, 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. It is not yet known whether cisplatin and fluorouracil are more effective than carboplatin and paclitaxel in treating anal cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. To evaluate best overall response rate (ORR).

SECONDARY OBJECTIVES:

I. Overall survival (OS). II. Progression free survival (PFS). III. Disease control rate (DCR) (stable disease \[SD\] or better) at 12 and 24 weeks.

IV. Best ORR of non-irradiated lesions. V. Anti-tumor activity and magnitude of response as captured by waterfall plot analyses.

VI. Toxicity. VII. Quality of life (QOL). VIII. Feasibility of conducting a multicenter international study on squamous cell carcinoma of the anus (SCCA) and recruit within a reasonable time frame.

TERTIARY OBJECTIVES:

I. Explorative biomarker analysis.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM A: Patients receive cisplatin intravenously (IV) over 1-4 hours on day 1 and fluorouracil IV continuously over 24 hours on days 1-4. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity. Patients with complications associated with the central venous access which prevent further infusion of fluorouracil and only after discussion with the Chief Investigator may receive capecitabine twice daily (BID) on days 1-4.

ARM B: Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15 and carboplatin IV over 30-60 minutes on day 1. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 12 weeks.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Arm A (cisplatin, fluorouracil or capecitabine)

Patients receive cisplatin IV over 1-4 hours on day 1 and fluorouracil IV continuously over 24 hours on days 1-4. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity. Patients with complications associated with the central venous access which prevent further infusion of fluorouracil and only after discussion with the Chief Investigator receive capecitabine BID on days 1-4.

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Inoperable, locally recurrent or metastatic disease (tumor resectability should be assessed by a local surgeon or multidisciplinary team)
* Histological or cytological confirmation of epidermoid anal carcinoma (includes squamous, basaloid and cloacogenic lesions) from the primary tumor or a newly diagnosed recurrent/metastatic lesion
* Eastern Cooperative Oncology Group (ECOG) performance status (PS) =\< 2
* Measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria version 1.1
* Previous definitive chemo-radiation is permitted for early stage tumors (cisplatin-based chemotherapy \[chemo\]-radiation is permitted but only if tumor progression/relapse occurs after 6 months from treatment completion)
* Previous systemic chemotherapy is permitted if administered as induction treatment (=\< 2 cycles) before definitive chemoradiotherapy for early stage disease and there is no evidence of tumor progression during or after treatment completion
* Human immunodeficiency virus positive (HIV+) patients will be considered eligible if they are on highly active anti-retroviral therapy (HAART) and have a cluster of differentiation (CD)4 count of \>= 200/ul (HIV+ patients who are on HAART and have a CD4 count \< 200/ul are eligible if the plasma viral load is below the level of detection according to the local assay)
* Absolute neutrophil count (ANC) \>= 1.5 x 10\^9/l
* Platelets \>= 100 x 10\^9/l
* Hemoglobin (Hb) \>= 9 g/dl for males and \>= 8 g/dl for females
