Brief Summary:

In the last ten years there have been significant developments in CLL treatment. The advent of fludarabine, rituximab and the association of chemo-immunotherapy have substantially increased overall response rate, CR rate, time to progression and may also have an impact on overall survival.

Even though, CLL remains incurable and all patients eventually relapse and progressively become resistant to treatment. The development of an effective therapy that is not cross-resistant with the ones currently available as front-line treatment, is one of the clinical unmet needs within CLL.

BendOfa is a non comparative phase II trial designed to determine the therapeutic benefit of bendamustine given together to ofatumumab in relapsed or resistant patients with CLL.

Bendamustine is approved by FDA for CLL treatment, it is an hybrid drug with alkylating agents and purine analogue properties that may lack of cross resistance with fludarabine. It was utilized in CLL as a single agent and its association with rituximab is currently under clinical investigation.

Ofatumumab is a new fully human anti-CD20 monoclonal antibody with high in vitro efficacy on CD20 low-expressing CLL cells. An early report showed that ofatumumab in single therapy is effective in highly pre-treated refractory CLL patients.

Both drugs were generally well tolerated without unexpected untoward toxicity. On the basis of these data, bendamustine and ofatumumab could be a new effective and well tolerated combination for patients with relapsed and refractory CLL.

Official Title: A Single-Arm Multi-Center Trial of Bendamustine Given With Ofatumumab (BendOfa) in Patients With Refractory or Relapsed Chronic Lymphocytic Leukemia (CLL). EudraCT Number 2009-017663-42. GIMEMA CLL0809 Protocol
Study Start Date : December 2010
Actual Primary Completion Date : July 2014
Actual Study Completion Date : July 2014


Arm Intervention/treatment
Experimental: Bendofa
Bendamustine + Ofatumumab
Drug: Ofatumumab
Ofatumumab will be administered at the dose of 300 mg IV D1 and 1000 mg IV D8 1st course; 1000 mg IV D1, 2nd -6th courses.

Drug: Bendamustine
Bendamustine will be infused at the doses of 70 mg/m2 IV on days D1 and D2 of each course.




Primary Outcome Measures :
  1. Number of Participants Contributing to the Overall Response Rate [ Time Frame: After 8 months from therapy start (6 months of treatment plus 2 months from the last course to response evaluation) ]
    Patients response to treatment will be assessed by clinical examination, peripheral blood, bone marrow aspirate and biopsy and radiographic evaluation according to the revised IWCLL 2008 criteria.


Secondary Outcome Measures :
  1. Toxicity According to CTCAE Version 4.0 [ Time Frame: At 44 months from treatment start. ]
    Number of patients experiencing 3 or >3 AEs (both hematological and not hematological)

  2. Progression Free Survival [ Time Frame: Up to 32 months: from the date of first BendOfa treatment dose - induction phase - until the date of the first documentation of progressive disease or until death (whatever the cause), whichever occurs first. ]
    Patients still alive and known to be progression-free will be censored at the moment of last follow-up. Patients disease progression will be assessed by clinical examination, peripheral blood, bone marrow aspirate and biopsy and radiographic evaluation according to the revised IWCLL 2008 criteria.

  3. Overall Survival [ Time Frame: At 44 months from treatment start. ]
    Patients still alive will be censored at the moment of last follow-up.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients with CLL relapsing after an initial response (CR, PR ≥ 6 months) following no more than two prior treatment lines; or
  • Patients with CLL refractory (SD, PD or CR/PR < 6 months) following no more than two prior treatment lines
  • Patients requiring treatment according to 2008 revised IWCLL guidelines
  • No more than 2 prior treatment lines
  • Age older or equal to 18 years
  • No active malignancies during the previous 5 years, with the exception of currently treated basal cell or squamous cell carcinoma of the skin, or carcinoma "in situ" of any origin
  • No prior treatment with conventional chemotherapy within the prior 4 weeks and with monoclonal antibodies within the prior 16 weeks
  • ECOG performance status of ≤2 at study entry
  • Laboratory test results within these ranges:

Serum creatinine ≤ 2 x UNL Creatinine clearance ≥ 50 ml/min (Cockcroft and Gault formula) Total bilirubin ≤ 2 x UNL (with exception of patients with Gilbert's syndrome) AST (SGOT) and ALT (SGPT) ≤ 2 x UNL non attributable to CLL AST (SGOT) and ALT (SGPT) ≤ 10 x UNL attributable to CLL

  • Female subjects of childbearing potential(FCBP) must:

Understands the potential teratogenic risk to the unborn child and the need for effective contraception;

Be capable of complying with effective contraceptive measures.

Be informed and understand the potential consequences of pregnancy and the need to notify her study doctor immediately if there is a risk of pregnancy.

Understand the need to commence the study treatment as soon as study drug is dispensed following a negative pregnancy test.

Understand the need and accepts to undergo pregnancy testing based on the frequency outlined in this protocol.

Females of childbearing potential (FCBP) enrolled in this protocol must agree to use two reliable forms of contraception simultaneously or to practice complete abstinence from heterosexual contact during the following time periods related to this study: 1) before starting study drug; 2) while participating in the study; 3) dose interruptions; and 4) for at least 28 days after study treatment discontinuation.

The two methods of reliable contraception must include one highly effective method and one additional effective (barrier) method. FCBP must be referred to a qualified provider of contraceptive methods if needed. The following are examples of highly effective and additional effective methods of contraception:

Highly effective methods:

  • Hormonal (birth control pills, injections, implants)
  • Tubal ligation
  • Partner's vasectomy

Additional effective methods:

  • Male condom
  • Diaphragm
  • Cervical Cap
  • Implants and levonorgestrel-releasing intrauterine systems are associated with an increased risk of infection at the time of insertion and irregular vaginal bleeding. Prophylactic antibiotics should be considered particularly in patients with neutropenia.
  • Pregnancy testing.

FCBP must have two negative pregnancy tests prior to starting study drug.

FCBP must agree to have a medically supervised pregnancy test every 4 weeks including 4 weeks after the end of study treatment, except in the case of confirmed tubal sterilization. This requirement also applies to women of childbearing potential who practice complete and continued abstinence.

Females must agree to abstain from breastfeeding during study participation and for at least 28 days after study drug discontinuation.

- Male patients must:

Understand the potential teratogenic risk if engaged in sexual activity with a pregnant female or a female of childbearing potential.

Must practice complete abstinence or agree to use a prophylactic during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions and for at least 6 months following study drug discontinuation, even if he has undergone a successful vasectomy.

If pregnancy or a positive pregnancy test does occur in the partner of a male study patient during study participation, the investigator must be notified immediately.

- Female and male patients

should be instructed never to give this medicinal product to another person and to return any unused capsules to the study doctor at the end of treatment.
