      Trial Summary

      This study will evaluate the safety, efficacy, and pharmacokinetics of mosunetuzumab or glofitamab in combination with CELMoDs (CC-220 and CC-99282) in participants with B-cell NHL.

      Why is the CO43805 clinical trial needed?

      B-cell non-Hodgkin lymphoma (NHL) is a common type of cancer that affects a type of immune cell called B cells. Although there has been progress in treating NHL, many people who have NHL may not respond to treatment (their disease is refractory) or will experience a relapse (their disease will get worse). This trial aims to test whether new drug combinations could help people with relapsed or refractory NHL to live longer, without intolerable side effects. 

       

      How does the CO43805 clinical trial work?

      This clinical trial is recruiting people who have a health condition called B-cell NHL. People can take part if they have relapsed or refractory NHL.

      The purpose of this clinical trial is to test the safety and effectiveness of CC-220 or CC-99282 when combined with mosunetuzumab or glofitamab and to understand the way the body processes these combinations.

      Participants will be given the clinical trial treatment CC-220 or CC-99282 in combination with mosunetuzumab (Group A) OR CC-220 or CC-99282 in combination with glofitamab (Group B) for up to 12 cycles of treatment. Participants will be seen by the clinical trial doctor every week during the first two to three cycles, then every 3 or 4 weeks in the remaining treatment cycles. These hospital visits will include checks to see how the participant is responding to the treatment and any side effects they may be having. Participants’ total time in the clinical trial will be up to roughly 3 years, as they will be seen for follow-up appointments every 3 months for 2 years after they have finished treatment. Participants are free to stop trial treatment and leave the clinical trial at any time.

       

      What are the main endpoints of the CO43805 clinical trial?

      The main clinical trial endpoints (the main results that are measured in the trial to see if the medicine has worked) are the type and number of dose-limiting toxicities (DLTs) and adverse events (AEs). DLTs are treatment side effects that are too severe to allow for an increase in the dose, and AEs are any unexpected medical problems that occur while receiving the treatment.

      Other clinical trial endpoints include the proportion of people who respond to their treatment during the clinical trial (complete response rate and overall response rate) and how long their response lasts (duration of response).

       

      Who can take part in this clinical trial?

      People can take part in this trial if they are at least 18 years old and have NHL that either failed to respond or relapsed after treatment with at least two previous lines of systemic therapy (treatment that travels through the bloodstream).

      People will not be able to take part in this trial if they are pregnant or breastfeeding, have certain other medical conditions or have previously received certain other treatments.

       

      What treatment will participants be given in this clinical trial?

      Everyone who joins this clinical trial will be put into groups depending on when they join and given either:

      • Group A: Mosunetuzumab as an injection under the skin (subcutaneous) on Days 1, 8 and 15 of Cycle 1, then Day 1 of Cycles 2–12 and CC-220 as a capsule to be swallowed once a day on Days 1–21 of Cycles 2–12 OR CC-99282 as a capsule to be swallowed once a day on Days 1–14 of Cycles 2–12. Cycle 1 will last for 21 days and Cycles 2–12 will last for 28 days
      • Group B: Glofitamab as an infusion into the vein on Days 8 and 15 of Cycle 1, then Day 1 of Cycles 2–12, and CC-220 as a capsule to be swallowed once a day on Days 1–14 of Cycles 3–12 OR CC-99282 as a capsule to be swallowed once a day on Days 1–10 of Cycles 3–12. Each cycle will last for 21 days. People in this group will also need to have one pre-treatment dose of obinutuzumab as an infusion into the vein on Day 1 of Cycle 1

      Participants may also receive tocilizumab as an infusion into the vein if they experience certain side effects during the clinical trial.

      This is an open-label clinical trial, which means that all participants will know which treatment they are receiving. 

       

          

      Are there any risks or benefits in taking part in this clinical trial?

      The safety or effectiveness of the experimental treatment or use may not be fully known at the time of the trial. Most trials involve some risks to the participant, although it may not be greater than the risks related to routine medical care or the natural progression of the health condition. Potential participants will be told about any risks and benefits of taking part in the clinical trial, as well as any additional procedures, tests, or assessments they will be asked to undergo. These will all be described in an informed consent document (a document that provides people with the information they need to make a decision to volunteer for a clinical trial). A potential participant should also discuss these with members of the research team and with their usual healthcare provider. Anyone interested in taking part in a clinical trial should know as much as possible about the trial and feel comfortable asking the research team any questions about the trial.

      Risks associated with the clinical trial drugs

      Participants may have side effects (an unwanted effect of a drug or medical treatment) from the drugs used in this clinical trial. Side effects can be mild to severe and even life-threatening, and can vary from person to person.

      Mosunetuzumab

      Potential participants will be told about the known side effects of mosunetuzumab and, where relevant, also potential side effects based on human and laboratory studies or knowledge of similar drugs.

      Mosunetuzumab will be given as a subcutaneous injection (inserting a needle into the fatty layer between the skin and muscle). Participants will be told about any known side effects of subcutaneous injections.

      Glofitamab, obinutuzumab and tocilizumab

      Potential participants will be told about the known side effects of glofitamab, obinutuzumab and tocilizumab and, where relevant, also potential side effects based on human and laboratory studies or knowledge of similar drugs.

      Glofitamab, obinutuzumab and tocilizumab are each given as an intravenous infusion (inserting a needle into a vein, usually in the arm). Participants will be told about any known side effects of intravenous infusions.

      CC-220 and CC-99282

      Potential participants will be told about the known side effects of CC-220 and CC-99282 and, where relevant, also potential side effects based on human and laboratory studies or knowledge of similar drugs.

      CC-220 and CC-99282 are each given as capsules to be swallowed with water (oral administration). Participants will be told about any known side effects of oral administration.

      Potential benefits associated with the clinical trial

      Participants' health may or may not improve from participation in the clinical trial, but the information that is collected may help other people who have a similar medical condition in the future.
