Genentech to Present New and Encouraging Long-term Follow-up Data Across Broad Hematology Portfolio at ASH 2024

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY) announced today that it will present more than 40 abstracts across nine blood disorders at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition, held December 7-10, 2024 in San Diego, California. The data underscore Genentech’s commitment to advance patient outcomes in lymphoma with long-term follow-up of its approved medicines Polivy^® (polatuzumab vedotin-piiq), Lunsumio^® (mosunetuzumab-axgb) and Columvi^® (glofitamab-gxbm) as well as new investigational combination data.

Key presentations include:

• Five-year data from the Phase III POLARIX study (abstract #469) reinforce the potential of Polivy in combination with Rituxan^® (rituximab), cyclophosphamide, doxorubicin and prednisone (R-CHP) to provide durable and lasting remissions and for the first time show a positive trend in overall survival (OS) for people with first-line diffuse large B-cell lymphoma (DLBCL), an area that previously had little advancement in nearly two decades.
• Extended follow-up data of up to four years from the pivotal GO29781 study of Lunsumio (abstract #4407) and NP30179 study of Columvi (abstract #865) show long-lasting remissions and immune system recovery after the end of treatment, supporting the use of fixed-duration bispecific antibodies for third-line or later (3L+) follicular lymphoma (FL) and DLBCL, respectively.
• First presentation of data for a subcutaneous formulation of Lunsumio monotherapy from the pivotal Phase II GO29781 study (abstract #1645) show high rates of deep and durable responses and low rates and severity of cytokine release syndrome in people with 3L+ FL. Subcutaneously administered Lunsumio could further improve the patient experience by combining shorter administration time with the existing benefits of a fixed-duration and outpatient therapy.
• New patient-reported outcomes data from the Phase III STARGLO study (abstract #5132) indicate comparable health-related quality of life between treatment arms, despite higher median number of cycles received with the Columvi combination (11 versus 4). Together with the significant improvement in OS observed in the study, these data support the potential benefit for patients with second-line or later DLBCL.
• New and updated data from investigational study combinations of Polivy with bispecific antibodies Lunsumio and Columvi in relapsed or refractory DLBCL, including the Phase Ib/II NP39488 (abstract #988) and Phase II GO40516 (abstract #989) studies, add to the growing body of evidence demonstrating the potential of novel bispecific antibody/Polivy combinations in earlier treatment lines, and support their ongoing Phase III development.

About Polivy^® (polatuzumab vedotin-piiq)

Polivy is a first-in-class anti-CD79b antibody-drug conjugate (ADC). The CD79b protein is expressed specifically in the majority of B cells, an immune cell impacted in some types of non-Hodgkin’s lymphoma (NHL), making it a promising target for the development of new therapies. Polivy binds to cancer cells such as CD79b and destroys these B cells through the delivery of an anti-cancer agent, which is thought to minimize the effects on normal cells. Polivy is being developed by Genentech using Seagen ADC technology and is currently being investigated for the treatment of several types of NHL.

Polivy U.S. Indication

Polivy is a prescription medicine used with other medicines (a rituximab product, cyclophosphamide, doxorubicin, and prednisone) as a first treatment for adults who have moderate to high risk diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS) or high-grade B-cell lymphoma (HGBL).

Polivy is a prescription medicine used with other medicines, bendamustine and a rituximab product, to treat DLBCL in adults who have progressed after at least 2 prior therapies.

About Lunsumio^® (mosunetuzumab-axgb)

Lunsumio is a first-in-class 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 program for Lunsumio is ongoing, investigating the molecule as a monotherapy and in combination with other medicines, for the treatment of people with B-cell non-Hodgkin’s lymphomas, including follicular lymphoma and diffuse large B-cell lymphoma, and other blood cancers.

Lunsumio U.S. Indication

Lunsumio (mosunetuzumab-axgb) is a prescription medicine used to treat adults with follicular lymphoma whose cancer has come back or did not respond to previous treatment, and who have already received two or more treatments for their cancer.

It is not known if Lunsumio is safe and effective in children.

The conditional approval of Lunsumio is based on response rate. There are ongoing studies to establish how well the drug works.

What is the most important information I should know about Lunsumio?

Lunsumio may cause Cytokine Release Syndrome (CRS), a serious side effect that is common during treatment with Lunsumio and can also be severe or life-threatening.

Get medical help right away if you develop any signs or symptoms of CRS at any time, including:

• fever of 100.4°F (38°C) or higher
• chills
• low blood pressure
• fast or irregular heartbeat
• tiredness or weakness
• difficulty breathing
• headache
• confusion
• feeling anxious
• dizziness or light-headedness
• nausea
• vomiting

Due to the risk of CRS, you will receive Lunsumio on a “step-up dosing schedule.”

• The step-up dosing schedule is when you receive smaller “step-up” doses of Lunsumio on Day 1 and Day 8 of your first cycle of treatment
• You will receive a higher dose of Lunsumio on Day 15 of your first cycle of treatment
• If your dose of Lunsumio is delayed for any reason, you may need to repeat the step-up dosing schedule
• Before each dose in Cycle 1 and Cycle 2, you will receive medicines to help reduce your risk of CRS

Your healthcare provider will check you for CRS during treatment with Lunsumio and may treat you in a hospital if you develop signs and symptoms of CRS. Your healthcare provider may temporarily stop or completely stop your treatment with Lunsumio, if you have severe side effects.

What are the possible side effects of Lunsumio?

Lunsumio may cause serious side effects, including:

• Neurologic problems. Your healthcare provider will check you for neurologic problems during treatment with Lunsumio.
