CHMP recommends EU conditional approval of Roche’s potential first-in-class bispecific antibody mosunetuzumab for people with relapsed or refractory follicular lymphoma
Roche announced the European Medicines Agency's CHMP recommendation for conditional marketing authorization for mosunetuzumab, a bispecific antibody for treating relapsed or refractory follicular lymphoma (FL). If approved, it will be the first CD20xCD3 therapy available for this condition. The recommendation stems from the GO29781 study, which demonstrated a 60% complete response rate among heavily pretreated patients. More than 28,000 people are diagnosed with FL yearly in Europe, highlighting the need for effective treatment options. A final decision by the European Commission is anticipated soon.
- CHMP recommendation for mosunetuzumab's conditional marketing authorization.
- 60% complete response rate in the GO29781 study.
- First-in-class bispecific antibody targeting CD20 and CD3.
- None.
- If approved, mosunetuzumab would be the first CD20xCD3 T-cell engaging bispecific antibody available to treat follicular lymphoma (FL) offering a new, off-the-shelf, fixed-duration treatment option
- The recommendation is based on the GO29781 study where mosunetuzumab induced high complete response rates, with the majority of complete responses lasting for at least 18 months in people with heavily pretreated FL
Basel, 22 April 2022 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended approval under conditional marketing authorisation for mosunetuzumab for the treatment of adult patients with relapsed or refractory (R/R) follicular lymphoma (FL), who have received at least two prior systemic therapies. Based on this positive CHMP opinion, a final decision regarding the conditional approval of mosunetuzumab is expected from the European Commission in the near future. Follicular lymphoma is the second most common form of lymphoma globally, accounting for
“The majority of people with follicular lymphoma experience frequent relapses, and with each successive therapy the duration of remission and survival shortens,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “Today’s decision acknowledges the potential of mosunetuzumab as an efficacious, readily available, fixed-duration option, and brings the possibility of new hope to people living with this disease.”
More than 28,000 people in Europe are diagnosed with FL each year.[1,2] The majority of people with FL relapse within five years after initial treatment, and for those who have received two or more prior therapies, conventional treatment options are currently limited and are associated with low rates of complete and durable remissions.[3,4] If approved, mosunetuzumab will be a first-in-class CD20xCD3 T-cell engaging bispecific antibody in NHL.
The CHMP recommendation is based on positive results from the phase I/II GO29781 study where mosunetuzumab showed high complete response (CR) rates, with the majority of complete responders maintaining responses for at least 18 months, and favourable tolerability in people with heavily pretreated FL. After a median follow-up of 18.3 months, the CR rate was
In June 2020, mosunetuzumab was granted Breakthrough Therapy Designation by the U.S. Food and Drug Administration for the treatment of adult patients with FL who have received at least two prior systemic therapies. A robust development programme for mosunetuzumab is ongoing including two phase III studies: CELESTIMO investigating mosunetuzumab plus lenalidomide in second line plus (2L+) FL, and SUNMO, investigating mosunetuzumab plus Polivy® (polatuzumab vedotin) in 2L+ diffuse large B-cell lymphoma (DLBCL).
This recommendation is Roche’s second CHMP positive opinion in NHL in 2022, following the positive opinion for Polivy in combination with MabThera® (rituximab) plus cyclophosphamide, doxorubicin and prednisone in previously untreated DLBCL.[6] With our broad portfolio and pipeline, we are committed to providing treatment solutions for different stages of blood disorders, that are tailored to the disease, patient, physician, and healthcare system, as monotherapies or in combination with established and/or novel agents.
About mosunetuzumab
Mosunetuzumab is an investigational CD20xCD3 T-cell engaging bispecific antibody designed to target CD20 on the surface of B-cells and CD3 on the surface of T-cells. This dual targeting activates and redirects a patient’s existing T-cells to engage and eliminate target B-cells by releasing cytotoxic proteins into the B-cells. A robust clinical development programme for mosunetuzumab is ongoing, investigating the molecule as a monotherapy and in combination with other medicines, for the treatment of people with B-cell non-Hodgkin lymphomas, including follicular lymphoma and diffuse large B-cell lymphoma, and other blood cancers.
About the GO29781 study
The GO29781 study [NCT02500407] is a phase I/II, multicentre, open-label, dose-escalation and expansion study evaluating the safety, efficacy and pharmacokinetics of mosunetuzumab in people with relapsed or refractory B-cell non-Hodgkin lymphoma. Outcome measures include complete response rate (best response) by independent review facility (primary endpoint), objective response rate, duration of response, progression-free survival, safety and tolerability (secondary endpoints).
About follicular lymphoma
Follicular lymphoma (FL) is the most common indolent (slow-growing) form of non-Hodgkin lymphoma (NHL), accounting for about one in five cases of NHL.[1] It is considered incurable and relapse is common. It is estimated that more than 100,000 people are diagnosed with FL each year worldwide, including over 28,000 people in Europe.[1,2]
