Phase 2 Trial of Obinutuzumab and CC-99282 for Patients With Previously Untreated High Tumor Burden Follicular Lymphoma

Description

To learn if obinutuzumab in combination with CC-99282 can help to control previously untreated, high tumor burden FLObjectives: Primary Objectives: • To determine the efficacy of obinutuzumab in combination with CC-99282 as determined by complete response (CR) rate after six cycles of combination treatment for patients with previously untreated, high tumor burden follicular lymphoma (FL). Secondary Objectives: • To determine best overall response rate (ORR), duration of response (DOR), time to next treatment, CR rate at 30 months (CR30), progression-free survival (PFS), overall survival (OS), and evaluation of safety of obinutuzumab and CC-99282 as treatment for previously untreated patients with FL. Exploratory Objective: * To determine the biomarkers that correlates with response and mechanisms of resistance to obinutuzumab and CC-99282 in FL. * To determine the quality of life in patients with FL receiving obinutuzumab and CC-99282

She must agree to ongoing pregnancy testing during the course of the study, and after end of study therapy. This applies even if the subject practices true abstinence\* from heterosexual contact. * Either commit to true abstinence\* from heterosexual contact (which must be reviewed on a monthly basis and source documented) or agree to use, and be able to comply with two forms of contraception: one highly effective, and one additional effective (barrier) measure of contraception without interruption 28 days prior to starting IP, during the study treatment (including dose interruptions), and for 6 months and 2 weeks for women and 3 months and 2 weeks for men after the last dose of CC-99282 and for 12 months after the last dose of obinutuzumab, whichever is longer. Contraception requirements are detailed in Appendix 14.1. * Male subjects must: * Practice true abstinence\* (which must be reviewed on a monthly basis and source documented) or agree to use a condom (Appendix 14.1) 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 3 months and 2 weeks after the last dose of CC-99282 or obinutuzumab, whichever is longer, even if he has undergone a successful vasectomy. * Must agree to refrain from donating sperm while on study treatment, during dose interruptions, and for at least 3 months and 2 weeks after the last dose of CC-99282 or obinutuzumab, whichever is longer. * Sign an informed consent document indicating that they understand the purpose of and procedures required for the study, including biomarkers, and are willing to participate in the study. The investigator is responsible for: ensuring that the patient understands the potential risks and benefits of participating in the study; ensuring that informed consent is given by each patient, this includes obtaining the appropriate signatures and dates on the informed consent document prior to the performance of any study procedures and prior to the administration of study treatment; answering any questions the patient may have throughout the study and sharing in a timely manner any new information that may be relevant to the patient's willingness to continue his or her participant in the trial. Subjects will undergo a brief physical exam including a brief exam to determine cognitive review. No one without capacity to personally consent will be enrolled. Patients have medical decision-making capacity if they can demonstrate understanding of the situation, appreciation of the consequences of their decision, and reasoning in their thought process, and if they can communicate their wishes. A determination of lack of decision-making capacity shall be made after an appropriate medical evaluation that concludes there is little or no likelihood that the participant will regain decision-making capacity in a reasonable period of time. §A FCBP is a female who: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy, or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months). \*True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. Exclusion Criteria: Subjects will be ineligible for this study if they meet any of following criteria: * Known active central nervous system lymphoma or leptomeningeal disease * Any prior history of other malignancy besides B-NHL, unless the patient has been free of disease for ≥ 3 years and felt to be at low risk for recurrence by the treating physician, except: * Adequately treated localized skin cancer without evidence of disease. * Adequately treated cervical carcinoma in situ without evidence of disease. * Any life-threatening illness, medical condition, or organ system dysfunction which, in the investigator's opinion, could compromise the subject's safety, interfere with the absorption or metabolism of lenalidomide capsules, or put the study outcomes at undue risk * Uncontrolled human immunodeficiency virus (HIV), or active Hepatitis C Virus, or active Hepatitis B Virus infection, or any uncontrolled active significant infection, including suspected or confirmed JC virus infection and SARS-CoV2 * Patients with inactive hepatitis B infection must adhere to hepatitis B reactivation prophylaxis unless contraindicated. Hepatitis B or C serologic status: subjects who are hepatitis B core antibody (anti-HBc) positive and who are surface antigen negative will need to have a negative polymerase chain reaction (PCR). Those who are hepatitis B surface antigen (HbsAg) positive or hepatitis B PCR positive will be excluded. Subjects who are hepatitis C antibody positive will need to have a negative PCR result. Those who are hepatitis C PCR positive will be excluded.
