Clinical Trial Summary

This phase I/II trial studies the side effects and best dose of alemtuzumab when given together with combination chemotherapy and to see how well it works in treating patients with untreated acute lymphoblastic leukemia. Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy also work in different ways to kill cancer cells or stop them from growing. Giving alemtuzumab together with combination chemotherapy may be a better way to block cancer growth.

Description:

PRIMARY OBJECTIVES:

I. To determine the feasibility and toxicity profiles of escalating doses of Campath-1H (alemtuzumab) given subcutaneously during post-remission intensification treatment of adults with acute lymphoblastic leukemia (ALL).

II. To determine the disease-free survival (DFS) and overall survival (OS) when Campath-1H is used during post-remission intensification treatment of adults with ALL.

III. To determine whether antibody treatment with Campath-1H can further reduce minimal residual disease states in adult ALL.

IV. To obtain preliminary descriptive data on serum levels of Campath-1H during course IV, module D using limited pharmacokinetic sampling during the phase I and II components of the study.

V. To obtain feasibility data on the addition of imatinib to Cancer and Leukemia Group B (CALGB) induction and postremission combination chemotherapy for patients with Philadelphia chromosome positive (Ph+) ALL.

OUTLINE: This is a dose-escalation study of alemtuzumab.

COURSE 1 (module A): Patients receive allopurinol orally (PO) 4 times daily (QID) on days 1-14, cyclophosphamide* intravenously (IV) over 15-30 minutes on day 1, daunorubicin hydrochloride IV on days 1-3, vincristine sulfate IV on days 1, 8, 15, and 22, dexamethasone PO twice daily (BID) on days 1-7 and 15-21, asparaginase subcutaneously (SC) on days 5, 8, 11, 15, 18, and 22, and filgrastim SC on days 4-11. Patients who are Ph+ also receive imatinib mesylate PO on days 15-28.

*Note: Patients who are = 60 years old do not receive cyclophosphamide.

COURSE 2 (module B): Patients receive methotrexate intrathecally (IT) on day 1, cytarabine IV over 3 hours on days 1-3, dexamethasone as eye drops QID on days 1-4, trimethoprim-sulfamethoxazole PO BID 3 times weekly on days 1-29, and cyclophosphamide, asparaginase and filgrastim as in course 1. Patients who are Ph+ also receive imatinib mesylate PO on days 1-28.

COURSE 3 (module C): Patients receive vincristine sulfate IV on days 1, 15, and 29, methotrexate IV over 3 hours and IT on days 1, 15, and 19, methotrexate PO every 6 hours on days 1-2, 15-16, and 29-30, mercaptopurine PO on days 1-35, leucovorin calcium IV on days 2, 16, and 30, leucovorin calcium PO every 6 hours on days 3-4, and trimethoprim-sulfamethoxazole PO BID 3 times weekly on days 1-43. Patients who are Ph+ also receive imatinib mesylate PO on days 1-42.

COURSE 4 (module D): Patients receive alemtuzumab SC 3 times weekly for 4 weeks and begin acyclovir PO QID for 6 months (continuing through course 8).

• Phase I Cohort 1: 10 mg

• Phase I Cohort 2: 20 mg

• Phase I Cohort 3/Phase II MTD: 30 mg

COURSE 5 (module A): Patients repeat course 1, minus allopurinol.

COURSE 6 (module B): Patients repeat course 2.

COURSE 7 (module C): Patients repeat course 3.

COURSE 8: Patients receive mercaptopurine PO, vincristine sulfate IV on day 1, dexamethasone PO on days 1-5, methotrexate PO on days 1, 8, 15, and 22, and trimethoprim-sulfamethoxazole PO BID 3 days weekly. Patients who are Ph+ also receive imatinib mesylate PO on days 1-28. Courses repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for 10 years.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Tolerated Dose (MTD) of Alemtuzumab (Phase I)	The maximum tolerated dose is defined as the highest alemtuzumab dose at which less than 40% of patients develop the dose limiting toxicity (DLT), where DLT is defined as the inability to proceed (due to medical complications) with the protocol treatment within six weeks of receiving the last dose of alemtuzumab. Groups of six patients will be enrolled into each cohort at the time of re-registration prior to starting Course IV. After a cohort has accrued 6 patients and at least 3 have completed the 2-6 week post alemtuzumab observation period without DLT, the incoming patients will be assigned to the next cohort in the table while the DLT and other toxicities continue to be assessed for the newly closed cohort. If less than 3 out of 6 enrolled patients in a cohort have completed the 2-6 week post alemtuzumab observation period without DLT, additional patients may continue to enroll in that same cohort, i.e., accrual will not be suspended while waiting for patient follow-up data.	6 weeks
Primary	Number of Participants Who Proceed to Course V Within 2-6 Weeks of the Last Dose of Alemtuzumab (Phase II)	The primary endpoint is the number of participants who are able to proceed to course V within two - six weeks of completion of course IV.	8 months
Secondary	Minimal Residual Disease (MRD) During Treatment With Alemtuzumab (Phase II)	Minimal Residual Disease measures the presence of of circulating leukemia cells in the body. Patients that report a Complete Response (CR) during treatment are further tested to determine the presence of small amounts of circulating leukemia cells. Here we report the number of patients who were MRD negative.	9 years 4 months
Secondary	Disease-free Survival, for Only Complete Response Patients	Disease Free Survival (DFS) is defined as the time from a Complete Response (CR) until death or relapse. The date of last clinical assesment will be used as the censor date for patients with no death or relapse. The DFS will be estimated using the Kaplan-Meier method with confidence intervals presented.	9 years 4 months
Secondary	Overall Survival	Overall Survival is defines as the time from registration to death due to any cause. It is estimated using the Kaplan-Meier method with confidence intervals presented.	9 years 4 months
