NCT02614508
First received: November 23, 2015
Last updated: September 15, 2016
Last verified: September 2016
  Purpose
This phase I trial studies the side effects and best dose of buparlisib when given together with ofatumumab or ibrutinib in treating patients with chronic lymphocytic leukemia that has returned after a period of improvement or does not respond to treatment. Buparlisib and ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as ofatumumab, may block cancer growth in different ways by targeting certain cells. Giving buparlisib or ibrutinib and ofatumumab together may work better in treating patients with chronic lymphocytic leukemia.

Detailed Description:

PRIMARY OBJECTIVES:

I. To evaluate the safety and dose limiting toxicities (DLT) of combined ofatumumab and buparlisib in patients with previously treated chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) who have been exposed to ibrutinib (i.e., ibrutinib pre-treated).

II. To evaluate the safety and dose limiting toxicities (DLT) of combined ibrutinib and buparlisib in patients with previously treated chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) who have NOT been exposed to ibrutinib (i.e., ibrutinib naïve)

SECONDARY OBJECTIVES:

I. To determine specific toxicities associated with combined buparlisib and ofatumumab.

II. Evaluate for efficacy of buparlisib in combination with ofatumumab in ibrutinib pre-treated patients with CLL/SLL.

III. To determine specific toxicities associated with combined buparlisib and ibrutinib.

IV. To evaluate for efficacy of buparlisib in combination with ibrutinib in ibrutinib naive patients with CLL/SLL.

OUTLINE: This is a dose escalation study of buparlisib. Patients are assigned to 1 of 2 treatment cohorts.

COHORT A (ibrutinib pre-treated): Patients receive buparlisib orally (PO) once daily (QD) on days 1-28 and ofatumumab intravenously (IV) on days 1, 8, 15, and 22 during of courses 1-2; and day 1 of courses 4-7. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

COHORT B (ibrutinib naive): Patients receive buparlisib as in Cohort A and ibrutinib PO on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

  • Patient who is not willing to apply highly effective contraception during the study and through the duration as defined below:

    • Sexually active males should use a condom during intercourse while taking drug and for 16 weeks after the final dose of study treatment and should not father a child in this period, but may be recommended to seek advice on conservation of sperm; a condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid
    • Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective contraception during the study and through at least 4 weeks after the final dose of study treatment
    • Highly effective contraception is defined as either:

      • Total abstinence: When this is in line with the preferred and usual lifestyle of the subject; (periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable methods of contraception)
      • Female sterilization: have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment; in case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
      • Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate); (for female study subjects, the vasectomized male partner should be the sole partner for that patient)
      • Use a combination of the following (both a+b):

  • Women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago; for women with therapy-induced amenorrhea, oophorectomy or serial measurements of follicle stimulating hormone (FSH) and/or estradiol are needed to ensure postmenopausal status; NOTE: Ovarian radiation or treatment with a luteinizing hormone-releasing hormone (LH-RH) agonist (goserelin acetate or leuprolide acetate) is not permitted for induction of ovarian suppression
  • Patients with a history of central nervous system involvement by CLL or who have prolymphocytic leukemia (PLL)
  • Patients with known hepatitis B or hepatitis C (active or carriers)
  • Patients with diarrhea ≥ CTCAE grade 2
  • Patients who have received oral or IV chemotherapy or targeted anticancer therapy ≤ 2 weeks (4 weeks for nitrosourea, antibodies or mitomycin-C) prior to study enrollment; steroids used for anti-cancer properties must be tapered to 10 mg or less of prednisone (or equivalent) for at least 2 weeks prior to initiating therapy
