Ordspono™ (odronextamab) approved in the European Union

by

On August 26, 2024, Regeneron announced that the European Commission approved Ordspono™ (odronextamab) to treat adult patients with relapsed or refractory (R/R) follicular lymphoma (FL) or R/R diffuse large B-cell lymphoma (DLBCL), after two or more lines of systemic therapy. This marks the first regulatory approval of Ordspono in the world for these patients.

Odronextamab (REGN1979) is a hinge-stabilized, bispecific human IgG4k antibody targeting CD20 and CD3 with an Fc that was modified to reduce Fc receptor binding. The antibody was derived from Regeneron’s VelocImmune® technology and Veloci-Bi® platform and is being developed for the treatment of RR B-cell NHL. In 2020, Regeneron granted Zai Lab rights to develop and exclusively commercialize odronextamab in oncology in mainland China, Hong Kong, Taiwan, and Macau. Odronextamab received Fast Track designation from FDA and Orphan Drug designations by the FDA and EMA for the treatment of patients with FL and DLBCL, which are subtypes of NHL.

The approval in the European Union is based on results from the Phase 1 ELM-1 (NCT02290951)  and pivotal Phase 2 ELM-2 (NCT03888105) trials, which demonstrated robust, durable response rates in adults with R/R FL or R/R DLBCL

  • Results from ELM-1 (N=60) in R/R DLBCL patients who had progressed after CAR-T therapy, as assessed by an independent review committee (IRC) showed 48% objective response rate (ORR), with 32% achieving a complete response (CR). Among responders (n=29), the median duration of response (DoR) was 15 months (95% CI: 3 months to not estimable (NE)).
  • Results from ELM-2 (N=127) in R/R DLBCL patients who were CAR-T therapy naive, as assessed by an IRC showed 52% ORR, with 31% achieving a CR. Among complete responders the median DoR was 18 months (95% CI: 10 months to NE).
  • In R/R FL, results from ELM-2 (N=128) as assessed by an IRC showed an objective response rate (ORR) of 80%, with 73% achieving a CR. Among complete responders, the median DoR was 25 months (95% confidence interval [CI]: 20 months to NE).

Regeneron submitted biologics license applications (BLAs) for odronextamab for RR FL and DLBCL to FDA. In March 2024, Regeneron announced that the FDA issued complete response letters for the Biologics License Applications for odronextamab. The company noted that FDA’s only approvability issue is related to the enrollment status of the confirmatory trials.

“Antibodies to Watch in 2024” is now online!

by

In this 15th installment of the annual ‘Antibodies to Watch’ article series, we review commercially sponsored monoclonal antibody therapeutics currently in late-stage clinical development, regulatory review, and those granted a first approval in any country in 2023. We also discuss clinical phase transition and overall approval success rates for antibody therapeutics, which are crucial to the biopharmaceutical industry because these rates inform decisions about resource allocation. Our analyses indicate that these molecules have approval success rates in the range of 14–32%, with higher rates associated with antibodies developed for non-cancer indications. Overall, our data suggest that antibody therapeutic development efforts by the biopharmaceutical industry are robust and increasingly successful.

The complete abstract is here: The ‘Antibodies to Watch’ article series provides an annual summary of commercially sponsored monoclonal antibody therapeutics currently in late-stage clinical development, regulatory review, and those recently granted a first approval in any country. In this installment, we discuss key details for 16 antibody therapeutics granted a first approval in 2023, as of November 17 (lecanemab (Leqembi), rozanolixizumab (RYSTIGGO), pozelimab (VEOPOZ), mirikizumab (Omvoh), talquetamab (Talvey), elranatamab (Elrexfio), epcoritamab (EPKINLY), glofitamab (COLUMVI), retifanlimab (Zynyz), concizumab (Alhemo), lebrikizumab (EBGLYSS), tafolecimab (SINTBILO), narlumosbart (Jinlitai), zuberitamab (Enrexib), adebrelimab (Arelili), and divozilimab (Ivlizi)). We briefly review 26 product candidates for which marketing applications are under consideration in at least one country or region, and 23 investigational antibody therapeutics that are forecast to enter regulatory review by the end of 2024 based on company disclosures. These nearly 50 product candidates include numerous innovative bispecific antibodies, such as odronextamab, ivonescimab, linvoseltamab, zenocutuzumab, and erfonrilimab, and antibody–drug conjugates, such as trastuzumab botidotin, patritumab deruxtecan, datopotamab deruxtecan, and MRG002, as well as a mixture of two immunocytokines (bifikafusp alfa and onfekafusp alfa). We also discuss clinical phase transition and overall approval success rates for antibody therapeutics, which are crucial to the biopharmaceutical industry because these rates inform decisions about resource allocation. Our analyses indicate that these molecules have approval success rates in the range of 14–32%, with higher rates associated with antibodies developed for non-cancer indications. Overall, our data suggest that antibody therapeutic development efforts by the biopharmaceutical industry are robust and increasingly successful.

Lebrikizumab (Ebglyss) approved in the European Union

by

On November 17, 2023, Almirall S.A. announced that the European Commission approved EBGLYSS (lebrikizumab) for the treatment of adult and adolescent patients (12 years and older with a body weight of at least 40 kg) with moderate-to-severe atopic dermatitis (AD), who are candidates for systemic therapy. Lebrikizumab (Ebglyss) is a humanized, hinge-stabilized (S228P mutation) IgG4k antibody that targets IL-13, a key mediator of the pro-inflammatory response and enhances neuronal responses to the persistent itch stimuli in atopic dermatitis.

The approval in the European Union is based on results from three phase 3 trials evaluating the safety and efficacy of lebrikizumab in adults and adolescents >12 years of age with atopic dermatitis. Advocate 1 (NCT04146363) and Advocate 2 (NCT04178967) are randomized, double-blind, placebo-controlled, parallel-group studies in which patients with moderate-to-severe atopic dermatitis received either an initial dose of 500 mg of lebrikizumab followed by 250 mg lebrikizumab Q2W, or placebo for a 16-week treatment period. Following the 16 weeks, patients who received a clinical response to lebrikizumab were re-randomized to receive lebrikizumab Q2W or Q4W, or placebo, for another 36 weeks. The primary endpoints were an Investigator Global Assessment (IGA) score of clear or almost clear (0 or 1, respectively) skin with reduction of at least two points from baseline and at and least 75% reduction in the Eczema Area and Severity Index (EASI-75) score. Both Advocate 1 and Advocate 2 met their primary endpoints, with the IGA outcome being achieved in 43.1% of the lebrikizumab cohort (n=283) compared to 12.7% in placebo cohort (n=141) for Advocate 1, and 33.2% of the lebrikizumab cohort (n=281) compared to 10.8% in the placebo cohort (n=146) for Advocate 2. [1] The third Phase 3 study, Adhere (NCT04250337), is a 16-week randomized, double-blind, parallel-group study which investigated the efficacy of lebrikizumab in combination with topical corticosteroids in 211 patients with AD. Patients were randomized 2:1 to receive either 250mg SC lebrikizumab Q2W after an initial loading dose of 500 mg, or placebo, in combination with topical steroids, either mid-potency (0.1% triamcinolone acetonide cream) or low-potency (1% hydrocortisone cream). After 16 weeks, IGA of 0 or 1 with a 2 or more-point reduction from baseline was achieved by 41.2% of the lebrikizumab cohort compared to 22.1% of the placebo cohort, with statistical significance being reached as early as 8 weeks. [2] There was also a significantly greater proportion of patients achieving EASI-75 responses.

Almirall licensed the rights to develop and commercialize lebrikizumab for the treatment of dermatology indications, including atopic dermatitis, in Europe. Eli Lilly and Company has exclusive rights for the development and commercialization of the product in the United States and the rest of the world, not including Europe. Lilly has submitted a marketing application for lebrikizumab for atopic dermatitis to the US Food and Drug Administration.

Antibodies to Watch in 2023

 

Thursday January 12, 2023, 11am ET / 4pm CET

Speakers: Drs. Janice Reichert, Silvia Crescioli, Alicia Chenoweth & Jyothsna Visweswaraiah

“Antibodies to Watch in 2023” highlights key events in commercial monoclonal antibody therapeutics development that occurred in 2022 and forecasts events that might occur in 2023. In this presentation, we will discuss the antibody therapeutics granted first approvals in either the United States or European Union in 2022, which include 4 bispecific antibodies ((tebentafusp, faricimab, mosunetuzumab and teclistamab) and 1 ADC (mirvetuximab soravtansine). We will also discuss approvals for antibody therapeutics that were first granted in China or Japan in 2022, which include 2 bispecific antibodies (cadonilimab and ozoralizumab). Globally, at least 24 investigational antibody therapeutics are undergoing review by regulatory agencies. Our data show that, with antibodies for COVID-19 excluded, the late-stage commercial clinical pipeline grew by ~20% in the past year to include nearly 140 investigational antibody therapeutics that were designed using a wide variety of formats and engineering techniques. Of those in late-stage development, marketing application submissions for at least 23 may occur by the end of 2023, of which 5 are bispecific (odronextamab, erfonrilimab, linvoseltamab, zanidatamab, and talquetamab) and 2 are ADCs (datopotamab deruxtecan, and tusamitamab ravtansine).

Everyone who registers will receive 3 reminders before the event, as well as the link to the On Demand version when it is available.

Tezspire (tezepelumab) approved in the European Union for severe asthma

by

On September 19, 2022, the European Commission (EC) approved AstraZeneca’s Tezspire (tezepelumab) as an add-on maintenance treatment in patients 12 years and older with severe asthma who are inadequately controlled with high dose inhaled corticosteroids plus another medicinal product in the European Union.

The EC’s approval was based on results from the PATHFINDER clinical trial program, which included the placebo-controlled NAVIGATOR Phase 3 trial (NCT03347279), which evaluated the effects of tezepelumab in adults and adolescents with severe uncontrolled asthma. In this study, patients received tezepelumab (210 mg; n=529) or placebo (n=532) SC every 4 weeks for 52 weeks. Tezspire demonstrated superiority across every primary and key secondary endpoint in patients with severe asthma, compared to placebo, when added to standard therapy in this study. For the tezepelumab group, the annualized rate of asthma exacerbations was 0.93 (95% CI, 0.80 to 1.07), while the rate was 2.10 (95% CI, 1.84 to 2.39) with placebo (rate ratio, 0.44; 95% CI, 0.37 to 0.53; P<0.001). Overall, data from the study indicated that, compared to those administered placebo, patients who received tezepelumab had fewer exacerbations and better lung function, asthma control, and health-related quality of life. Full results of the NAVIGATOR trial were published in The New England Journal of Medicine in May 2021.

Tezspire has been approved in the US and other countries for the treatment of severe asthma.
