Study Details

Study Description

Brief Summary

This phase II trial studies how well ruxolitinib phosphate works in treating patients with previously untreated chronic lymphocytic leukemia/small lymphocytic lymphoma. Ruxolitinib phosphate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Condition or Disease	Intervention/Treatment	Phase
Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma; Untreated Chronic Lymphocytic Leukemia	Drug: Ruxolitinib; Drug: Ruxolitinib Phosphate	Phase 2

Detailed Description

PRIMARY OBJECTIVES:

1. To determine the effect of ruxolitinib phosphate (ruxolitinib) in patients with high-risk chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who do not require anti-neoplastic therapy according to the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 recommendations and were either previously untreated or treated with

Ibrutinib for less than 3 months and were deemed Ibrutinib intolerant:

Ia. On disease burden. Ib. The rate of complete response (CR) and partial response (PR) as assessed by the IWCLL 2008 response criteria.

SECONDARY OBJECTIVES:

1. To evaluate the time to next treatment of high-risk CLL/SLL who do not require anti-neoplastic therapy according to the IWCLL 2008 recommendations.

OUTLINE:

Patients receive ruxolitinib phosphate orally (PO) twice daily (BID). Treatment continues for up to 3 years in the absence of disease progression or unacceptable toxicity. Treatment beyond 3 years may be permitted after discussion with the principal investigator.

After completion of study treatment, patients are followed up at 30 days.

Outcome Measures

Primary Outcome Measures

1. Participants With a Clinical Response [Up to 6 months after initiation of therapy]

   Clinical response will be assessed based on physical examination, complete blood count (CBC), a bone marrow aspiration, a whole body CT scan to be done at screening and 6 + 2 months in accordance with the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) guidelines (Hallek et al., 2008)

2. Number of Participants With Change of Tumor Burden [6 months after initiation of therapy]

   Tumor burden will be assessed by bone marrow aspiration, whole body CT scan at screening and 6 months.

3. Participants With a Response [Up to 30 days]

   Response Rate is Complete Response (CR) or Partial Response (PR). CR is absence of Lymphadenopathy, Hepatomegaly or Splenomegaly, lymphocytes < 4000/ul, normocellular, <30% lymphocytes, no B-lymphoid nodules, Platelets > 100,000/ul, hemoglobin >11.0 g/dl and Neutrophils >1500/ul. PR is >/= 50% decrease in lymphadenopathy, hepatomegaly, splenomegaly and Blood Lymphocytes from baseline, 50% reduction in marrow infiltrate or B-lymphoid nodules. Platelet count > 100,000/ul, Hemoglobin > 11 g/dl and Neutrophils >1500/ul or increase >/= 50% of all over base.

4. Time to Next Treatment [Up to 30 days]

   Number of months to subsequent therapy per patient.

Exclusion:

Subjects of childbearing potential who are unwilling to take appropriate precautions (throughout the study from screening including 30 days after discontinuation of the study drug) to avoid becoming pregnant or fathering a child. A) Females of non-childbearing potential are defined as women who (a) are equal to or greater than 55 years of age with history of amenorrhea for 1 year, OR (b) are surgically sterile for at least 3 months. B) For females of childbearing potential, or for males, appropriate precautions are those that are at least 99% effective in preventing the occurrence of pregnancy. These methods should be communicated to the subjects and their understanding confirmed: a) Double barrier methods; b) Condom with spermicide in conjunction with use of an intrauterine device (IUD); c) Condom with spermicide in conjunction with use of a diaphragm; d) Oral, injectable, or implanted contraceptives;

2. Subjects with inadequate liver or renal function at screening and baseline visits: A) Alanine aminotransferase (ALT) > 2.5x Upper limit of normal (ULN). B) Modification of Diet in Renal Disease (MDRD) calculated GFR < 30 mL/min

3. Subjects with active uncontrolled infection or who are HIV positive (Subjects with acute infections requiring treatment should delay screening/enrollment until the course of therapy has been completed and the event is considered controlled).

4. Subjects with a history of or a current malignancy except for treated basal or squamous carcinomas of the skin completely resected.

5. Subjects with clinically significant uncontrolled cardiac disease.

6. Subjects being treated concurrently with any prohibited medications, including investigational medication, rifampin, St. John's wort, and potent CYP3A4 inhibitors (excluding ketoconazole) unless continuation of such medications are determined by the investigator to be in the best interest of the patient.
