FDA Approves Genentech’s Columvi, the First and Only Bispecific Antibody With a Fixed-Duration Treatment for People With Relapsed or Refractory Diffuse Large B-Cell Lymphoma

On June 15, 2023 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported that the U.S. Food and Drug Administration (FDA) has approved Columvi (glofitamab-gxbm) for the treatment of adult patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) not otherwise specified or large B-cell lymphoma (LBCL) arising from follicular lymphoma, after two or more lines of systemic therapy (Press release, Genentech, JUN 15, 2023, View Source [SID1234632732]). This indication is approved under accelerated approval based on response rate and durability of response in the Phase I/II NP30179 study. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. Columvi will be available in the United States in the coming weeks.

"People with diffuse large B-cell lymphoma who have gone through multiple lines of therapy have a poor prognosis and desperately need additional treatment options," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "As an off-the-shelf, fixed-duration treatment providing durable response rates, we believe Columvi could change the way this aggressive lymphoma is treated, reinforcing our dedication to bringing innovative treatment options to people with critical unmet needs."

DLBCL is an aggressive, hard-to-treat disease and is the most common form of non-Hodgkin’s lymphoma in the United States. While many people with DLBCL are responsive to treatment, the majority of those who relapse or are refractory to subsequent treatments have poor outcomes.

"Patients with relapsed or refractory diffuse large B-cell lymphoma may experience rapid progression of their cancer and often urgently need an effective treatment option that can be administered without delay," said Krish Patel, M.D., Director of the Lymphoma Program at the Swedish Cancer Institute in Seattle and investigator of the Columvi Phase I/II NP30179 study. "Experience from clinical trials demonstrates that Columvi can provide patients with relapsed or refractory diffuse large B-cell lymphoma a chance for complete remission with a fixed-duration immunotherapy and that such remissions can potentially be sustained after the end of their treatment."

The FDA accelerated approval is based on positive results from the Phase I/II NP30179 study of Columvi given as a fixed course for 8.5 months in 132 patients with DLBCL who had relapsed or were refractory to prior therapies, including about one-third (30%) who had received prior CAR T-cell therapy. Additionally, 83% were refractory to their most recent therapy. Results showed patients treated with fixed-duration Columvi achieved durable remission, with 56% of patients achieving an overall response (OR; 74/132 [95% confidence interval (CI): 47-65]) and 43% of patients achieving a complete response (CR; 57/132 [95% CI: 35-52]). Over two-thirds of those who responded continued to respond for at least nine months (68.5% [95% CI: 56.7-80.3]). The OR rate is the combination of CR rate (a disappearance of all signs and symptoms of cancer) and partial response rate (a decrease in the amount of cancer in the body). The median duration of response was 1.5 years (18.4 months [95% CI: 11.4-not estimable]). Data from the NP30179 study were recently published in the New England Journal of Medicine.

Among 145 patients who received Columvi in the study, the most common adverse events (AEs) were cytokine release syndrome (CRS; 70%), which may be serious or life-threatening, musculoskeletal pain (21%), fatigue (20%) and rash (20%). CRS was generally low grade (52% experienced Grade 1, and 14% experienced Grade 2).

Columvi is the first and only CD20xCD3 T-cell engaging bispecific antibody for the treatment of R/R DLBCL that is given for a defined period of time. Unlike treat-to-progression approaches where treatment is given indefinitely until the cancer progresses or the therapy cannot be tolerated, Columvi is administered in 13 intravenous infusions over a maximum of 12 cycles (including step-up dosing) or until disease progression or the treatment cannot be tolerated, whichever occurs first. After Cycle 1, Columvi is administered once every three weeks. Designed to be completed in approximately 8.5 months, Columvi offers people with R/R DLBCL a target end date for their course of treatment and the possibility of a treatment-free period. Additionally, Columvi is a chemotherapy-free treatment option that is off-the-shelf and ready for infusion. Patients are pretreated with a single dose of obinutuzumab seven days prior to starting Columvi. Patients are also given a corticosteroid, an antipyretic (fever-reducing medicine) and an antihistamine as premedications to reduce the risk of CRS.

Columvi is part of Genentech’s broad and industry-leading CD20xCD3 T-cell-engaging bispecific antibody clinical development program. This includes the Phase III STARGLO study evaluating Columvi in combination with gemcitabine and oxaliplatin (GemOx) versus rituximab in combination with GemOx in patients with DLBCL who have been treated with one or more previous therapies and are ineligible for autologous stem cell transplant. Genentech’s hematology bispecific antibody portfolio also includes Lunsumio (mosunetuzumab-axgb), which was granted accelerated approval by the FDA in December 2022 for the treatment of adult patients with R/R follicular lymphoma after two or more lines of systemic therapy. Genentech is exploring the potential of both Columvi and Lunsumio as monotherapies and in combination with other therapies, including Polivy (polatuzumab vedotin-piiq), in earlier lines of treatment with the goal of providing patients with long-lasting outcomes. This robust development program includes two Phase III studies: CELESTIMO, investigating Lunsumio plus lenalidomide in second line plus (2L+) FL, and SUNMO, investigating Lunsumio plus Polivy in 2L+ DLBCL. Columvi received its first worldwide approval in Canada, and the European Medicines Agency’s Committee for Medicinal Products for Human Use recently granted a positive opinion recommending its approval.

Genentech is committed to helping people access the medicines they are prescribed and will be offering comprehensive services for people prescribed Columvi to help minimize barriers to access and reimbursement. For people who qualify, Genentech plans to offer patient assistance programs through Genentech Access Solutions. More information is also available at 866-4ACCESS/866-422-2377 or View Source

About the NP30179 Study
The NP30179 study [NCT03075696] is a Phase I/II, multicenter, open-label, dose-escalation and expansion study evaluating the safety, efficacy and pharmacokinetics of Columvi (glofitamab-gxbm) in people with relapsed or refractory diffuse large B-cell lymphoma. Outcome measures include complete response rate by an independent review committee (primary endpoint), overall response rate, duration of response, progression-free survival, safety and tolerability (secondary endpoints).

About Diffuse Large B-Cell Lymphoma
Diffuse large B-cell lymphoma (DLBCL) is an aggressive (fast-growing) blood cancer and is the most common form of non-Hodgkin’s lymphoma (NHL) in the U.S. While many people with DLBCL are responsive to treatment, the majority of those who relapse or are refractory to subsequent treatments have poor outcomes. DLBCL not otherwise specified is the most common category of large B-cell lymphoma (LBCL) and accounts for about 80% or more of cases. It applies to cases that do not fall into any specific disease subgroups of LBCL.

About Large B-Cell Lymphoma Arising from Follicular Lymphoma

Follicular lymphoma (FL) is the most common slow-growing (indolent) form of non-Hodgkin’s lymphoma (NHL), accounting for about one in five cases. It typically responds well to treatment but is often characterized by periods of remission and relapse. The disease typically becomes harder to treat each time a patient relapses, and early progression can be associated with poor long-term prognosis. As part of the natural history of FL, it can transform to more aggressive malignancies, including large B-cell lymphoma (LBCL), one of the most aggressive (fast-growing) blood cancers.

About Columvi (glofitamab-gxbm)
Columvi is a CD20xCD3 T-cell engaging bispecific antibody designed with a novel 2:1 structural format. Columvi targets both T cells, a type of immune cell, and B cells, which are cancerous in DLBCL. Columvi is engineered to have one region that binds to CD3, a protein on T cells, and two regions that bind to CD20, a protein on B cells, which can be healthy or cancerous. This dual-targeting brings the T cell in close proximity to the B cell, activating the release of cancer cell-killing proteins from the T cell that result in the death of B cells. A robust clinical development program for Columvi 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 diffuse large B-cell lymphoma and other blood cancers.

Columvi U.S. Indication

Columvi (glofitamab-gxbm) is a prescription medicine to treat adults with certain types of diffuse large B-cell lymphoma (DLBCL) or large B-cell lymphoma (LBCL) that has come back (relapsed) or that did not respond to previous treatment (refractory), and who have received 2 or more prior treatments for their cancer.

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

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

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

Columvi can cause Cytokine Release Syndrome (CRS), a serious side effect that is common during treatment with Columvi, and can also be serious and lead to death.

Call your healthcare provider or get emergency medical help right away if you develop any signs or symptoms of CRS, including:

fever of 100.4°F (38°C) or higher
chills or shaking
fast or irregular heartbeat
dizziness or light-headedness
trouble breathing
shortness of breath
Due to the risk of CRS, you will receive Columvi on a "step-up dosing schedule".

A single dose of a medicine called obinutuzumab will be given to you on the first day of your first treatment cycle (Day 1 of Cycle 1).
You will start the Columvi step-up dosing schedule a week after the obinutuzumab dose. The step-up dosing schedule is when you receive smaller "step-up" doses of Columvi on Day 8 and Day 15 of Cycle 1. This is to help reduce your risk of CRS. You should be hospitalized during your infusion and for 24 hours after receiving the first step-up dose on Day 8. You should be hospitalized during your infusion and for 24 hours after receiving the second step-up dose on Day 15 if you experienced CRS during the first step-up dose.
You will receive your first full dose of Columvi a week after the second step-up dose (this will be Day 1 of Cycle 2).
If your dose of Columvi is delayed for any reason, you may need to repeat the "step-up dosing schedule".
If you had more than mild CRS with your previous dose of Columvi, you should be hospitalized during and for 24 hours after receiving your next dose of Columvi.
Before each dose of Columvi, you will receive medicines to help reduce your risk of CRS and infusion-related reactions.
Your healthcare provider will monitor you for CRS during treatment with Columvi 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 Columvi if you have severe side effects.

Carry the Columvi Patient Wallet Card with you at all times and show it to all of your healthcare providers. The Columvi Patient Wallet Card lists the signs and symptoms of CRS you should get emergency medical help for right away.

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.

Important Safety Information

Mersana Therapeutics Announces Partial Clinical Hold on UP-NEXT and UPGRADE-A Clinical Trials

On June 15, 2023 Mersana Therapeutics, Inc. (NASDAQ: MRSN), a clinical-stage biopharmaceutical company focused on discovering and developing a pipeline of antibody-drug conjugates (ADCs) targeting cancers in areas of high unmet medical need, reported that the U.S. Food and Drug Administration (FDA) has issued a partial clinical hold pausing new patient enrollment in UP-NEXT and UPGRADE-A, the company’s ongoing clinical trials of UpRi in platinum-sensitive ovarian cancer (Press release, Mersana Therapeutics, JUN 15, 2023, View Source [SID1234632729]). UPLIFT, Mersana’s ongoing clinical trial of UpRi in platinum-resistant ovarian cancer, completed enrollment in October 2022. Patients who are already enrolled in these trials may continue receiving UpRi. Mersana expects to lock its UPLIFT clinical trial database and disclose UPLIFT top-line data by early August.

The partial clinical hold follows a submission by Mersana of a recent aggregate safety report of all patients dosed with UpRi (approximately 560 patients) evaluating bleeding events. As noted in FDA guidance, aggregate analyses generally become more informative as a drug progresses through development and accumulates data. Detection of a clinically meaningful risk, particularly in single-arm clinical trials, typically requires a large safety database to detect differences in rates of adverse events compared to those that are expected in the population being studied.

Although data on the background rate of bleeding in platinum-resistant ovarian cancer are limited, Mersana’s recent assessment determined that serious bleeding events appear to occur at a higher rate than background. While most bleeding cases in this aggregate safety analysis were low-grade, five (<1%) Grade 5 (fatal) bleeding events were observed among the approximately 560 patients dosed to date. The causes of bleeding events remain under investigation.

"Patient safety is always at the forefront for us, and work is now underway to compile further analyses that may inform FDA," said Anna Protopapas, President and Chief Executive Officer of Mersana Therapeutics. "Additionally, with UPLIFT top-line data on the near-term horizon, we will soon have a much more complete assessment of both the efficacy and safety profile for UpRi in platinum-resistant ovarian cancer."

The company is awaiting the FDA’s written correspondence regarding the partial clinical hold and expects the FDA will request a comprehensive assessment of UpRi safety data, inclusive of bleeding events. In addition, Mersana plans to submit to the FDA the UPLIFT safety and efficacy data once available. The company plans to seek alignment with the FDA to lift the partial clinical hold and resume enrollment in UP-NEXT and UPGRADE-A.

Iovance Biotherapeutics Announces First Patient Randomized in Phase 3 TILVANCE-301 Trial in Frontline Advanced Melanoma

On June 15, 2023 Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a biotechnology company focused on innovating, developing, and delivering novel polyclonal tumor infiltrating lymphocyte (TIL) therapies for patients with cancer, reported that the first patient was recently randomized in TILVANCE-301, a global, multicenter, registrational Phase 3 trial comparing Iovance TIL therapy lifileucel in combination with pembrolizumab versus pembrolizumab monotherapy in frontline advanced (unresectable or metastatic) melanoma (Press release, Iovance Biotherapeutics, JUN 15, 2023, View Source [SID1234632727]).

Friedrich Graf Finckenstein, M.D., Chief Medical Officer of Iovance, stated, "Our strategy is to offer TIL therapy across all lines of treatment for patients with advanced melanoma. Randomizing the first patient in TILVANCE-301, our first Phase 3 trial at Iovance, is an important milestone. The trial offers TIL therapy as part of an earlier treatment approach for frontline advanced melanoma, while serving as a confirmatory trial to convert an accelerated approval to full approval for lifileucel in post-anti-PD-1 melanoma. TILVANCE-301 is expected to be well underway at the time of potential accelerated approval in this initial indication. This trial may also provide important insights into the Iovance platform approach for TIL and anti-PD-1 therapy combinations in additional solid tumors."

TILVANCE-301 builds on Iovance clinical data and decades of experience at the National Cancer Institute (NCI) on the use of TIL therapy in early line advanced melanoma patients. An oral session at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting in November 2021 highlighted positive results for Iovance TIL therapy in combination with pembrolizumab in patients with advanced melanoma, cervical and head and neck cancers who were naïve to prior anti-PD-1 therapy. In April 2022, Iovance announced updated positive results demonstrating a 67% ORR and durability of response for lifileucel in combination with pembrolizumab in advanced melanoma from Cohort 1A of the IOV-COM-202 trial, which have remained consistent in nearly 20 patients treated to date.

The U.S. Food and Drug Administration (FDA) previously agreed that dual primary endpoints of objective response rate (ORR) and progression free survival (PFS) in TILVANCE-301 can support accelerated and full approvals of lifileucel in frontline advanced melanoma. The FDA also agreed that TILVANCE-301, which is expected to be well underway at the time of a potential accelerated approval of lifileucel in post-anti-PD-1 melanoma, can serve as the confirmatory trial for full approval in this initial indication. The FDA granted Priority Review for lifileucel in post-anti-PD-1 melanoma and assigned November 25, 2023, as the target action date for a decision under the Prescription Drug User Fee Act (PDUFA).

About TILVANCE-301
TILVANCE-301 will randomize approximately 670 patients to investigate the safety and efficacy of lifileucel in combination with pembrolizumab (experimental arm) compared with pembrolizumab monotherapy (control arm). Trial sites are actively enrolling adult participants with unresectable or metastatic melanoma who have not received prior therapy for advanced disease. Participants randomized to the control arm who experience disease progression may be treated with lifileucel monotherapy in an optional crossover period.

In addition to presentations from the executive management from MEI and Infinity on the three programs, the webcast includes commentary and discussion with Dr. Ezra Cohen, a recognized expert in the treatment of squamous cell carcinoma of the head & neck (SCCHN) and recently the Chief, Division of Hematology-Oncology, and Associate Director of Clinical Science at UC San Diego Moores Cancer Center. Following the prepared presentations, Dr. Nick Abbott, most recently the senior sell side biotech analyst at Wells Fargo Securities will ask questions of the presenters, Dr. Robert Ilaria, Dr. Ezra Cohen and Dr. Richard Ghalie.

The combined company’s development pipeline consists of three differentiated programs. All three clinical-stage development programs have the potential, in combination with current therapies, to overcome known resistance mechanisms and meaningfully improve patient outcomes:

Eganelisib, an oral immuno-oncology macrophage reprogramming product candidate, which is planned to be evaluated in combination with the PD-1 targeted checkpoint inhibitor pembrolizumab (KEYTRUDA) in patients with head and neck squamous cell carcinoma (HNSCC);
Voruciclib, an oral CDK9 inhibitor, currently being studied in combination with venetoclax (VENCLEXTA) in patients with hematologic malignancies; and
ME-344, a novel tumor selective mitochondrial inhibitor targeting the OXPHOS pathway, to be evaluated in combination with bevacizumab (AVASTIN) in patients with relapsed colorectal cancer.
