简要总结
A Phase 3 clinical trial to examine the efficacy of duvelisib monotherapy versus ofatumumab monotherapy in subjects with relapsed or refractory Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL).
详细描述
This is an open-label, two- arm, randomized phase 3, superiority trial designed to evaluate the efficacy and safety of duvelisib compared to ofatumumab administered to patients who have been diagnosed with CLL/SLL whose disease is relapsed or refractory.
Approximately 150 subjects will receive a starting dose of 25 mg duvelisib BID initially over the course of 21-day treatment cycle followed by 28-day treatment cycles for up to 18 cycles or until disease progression or unacceptable toxicity (whichever comes first). After 18 complete cycles of treatment, subjects may receive additional cycles of duvelisib until disease progression or unacceptable toxicity if they, in the judgment of the Investigator, may derive benefit from continued treatment, and if the subject meets the criteria for additional treatment at Cycle 19 Day 1.
Approximately 150 subjects will receive a starting dose of 300 mg ofatumumab on Day 1 followed by seven weekly doses of 2000 mg. Thereafter, subjects will receive 2000 mg ofatumumab once every month for four months. Administration of ofatumumab will not exceed the 12 doses (within 7 cycles).

入选标准
- •Diagnosis of active CLL or SLL that meets at least one of the IWCLL 2008 criteria for requiring treatment (Binet Stage ≥ B and/or Rai Stage ≥ I)
- •Disease that has progressed during or relapsed after at least one previous CLL/SLL therapy
- •Not appropriate for treatment with a purine-based analogue regimen (per National Comprehensive Cancer Network [NCCN] or European Society for Medical Oncology [ESMO] guidelines), including relapse ≤ 36 months from a purine-based chemoimmunotherapy regimen or relapse ≤ 24 months from a purine-based monotherapy regimen
- •A cytogenetics or fluorescence in situ hybridization (FISH) analysis of the leukemic cells within 24 months of randomization is required to document the presence or absence of del(17p). Note: if a sample from within 24 months is not available, it should be evaluated as part of the screening laboratory evaluation to inform stratification
- •Measurable disease with a lymph node or tumor mass > 1.5 cm in at least one dimension as assessed by computed tomography (CT)
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2 (corresponds to Karnofsky Performance Status [KPS] ≥ 60%)
- •Willingness by subject to be randomized to receive either ofatumumab or duvelisib at the dose and schedule defined in the protocol
- •Must meet the following laboratory parameters:
- •Serum aspartate transaminase (AST/SGOT) or alanine transaminase (ALT/SGPT) ≤ 3 x upper limit of normal (ULN)
- •Total bilirubin ≤ 1.5 x ULN
- •Serum creatinine ≤ 2.0 x ULN
- •Hemoglobin ≥ 8.0 g/dL with or without transfusion support
- •Platelet count ≥ 10,000 μL with or without transfusion support
- •For women of childbearing potential (WCBP): negative serum β-human chorionic gonadotropin (βhCG) pregnancy test within 1 week before randomization (WCBP defined as a sexually mature woman who has not undergone surgical sterilization or who has not been naturally post-menopausal for at least 24 consecutive months [women ≤ 55 years] or 12 consecutive months [women > 55 years])
- •Willingness of male and female subjects who are not surgically sterile or postmenopausal to use medically acceptable methods of birth control from the first dose of study drug to 30 days after the last dose of duvelisib and for 12 months after last dose of ofatumumab. Sexually active men, and women using oral contraceptive pills, should also use barrier contraception
- •Ability to voluntarily sign consent for and adhere to the entire study visit schedule and all protocol requirements
- •Signed and dated institutional review board (IRB)/independent ethics committee (IEC)-approved informed consent form (ICF) before any study specific screening procedures are performed
排除标准
- •History of Richter's transformation or prolymphocytic leukemia
- •Uncontrolled autoimmune hemolytic anemia (AIHA) or idiopathic thrombocytopenia purpura (ITP) that is uncontrolled or requiring > 20 mg once daily (QD) of prednisone (or equivalent) to maintain hemoglobin > 8.0 g/dL or platelets > 10,000 μL without transfusion support
- •Refractory to ofatumumab (progression or relapse <12 months of receiving ofatumumab therapy or <24 months of receiving an ofatumumab- containing regimen)
- •Prior allogeneic transplant (prior autologous stem cell transplant >6 months prior to study entry is permitted)
- •Known central nervous system lymphoma or leukemia; subjects with symptoms of CNS disease must have a negative CT scan or negative diagnostic lumbar puncture prior to randomization
- •Use of any of the following medications or procedures within the specified timeframe:
- •Use of live or live attenuated vaccines within 30 days prior to randomization
- •Chemotherapy, radiation therapy, or ablative therapy within 3 weeks of randomization
- •Tyrosine kinase inhibitor within 7 days of randomization
- •Other investigational therapy (not included above) within 3 weeks of randomization

- •Ongoing treatment with chronic immunosuppressants (eg, cyclosporine) or systemic steroids > 20 mg prednisone (or equivalent) QD
- •History of tuberculosis treatment within the preceding two years
- •Ongoing systemic bacterial, fungal, or viral infections at the time of initiation of study treatment (defined as requiring IV antimicrobial, antifungal or antiviral agents)
- •Subjects on antimicrobial, antifungal or antiviral prophylaxis are not specifically excluded if all other inclusion/exclusion criteria are met and there is no evidence of active infection at randomization
- •Human immunodeficiency virus (HIV) infection
- •Prior, current, or chronic hepatitis B or hepatitis C infection
- •History of alcohol abuse or chronic liver disease (other than metastatic disease to the liver)
- •Unable to receive prophylactic treatment for pneumocystis or herpes simplex virus (HSV)
