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.

FDA approves Omvoh™ (mirikizumab-mrkz)

by

On October 26, 2023, Eli Lilly and Company announced that the U.S. Food and Drug Administration approved Omvoh™ (mirikizumab-mrkz) infusion (300 mg/15 mL)/injection (100 mg/mL) for the treatment of moderately to severely active ulcerative colitis (UC) in adults. The approval was based on results from the LUCENT program, which included two randomized, double-blind, placebo-controlled Phase 3 clinical trials consisting of one 12-week induction study (UC-1) and one 40-week maintenance study (UC-2) for 52 weeks of continuous treatment.

Mirikizumab (LY3074828) is a humanized IgG4ҡ monoclonal antibody that blocks the activity of interleukin 23 by targeting the p19 subunit the cytokine. The antibody is engineered with the following mutations: S228P for hinge stabilization, F234A and L235A to abrogate effector function, and K447> del to reduce IgG4 C-terminal heterogeneity.

The recommended induction dosage is 300 mg administered by intravenous infusion over at least 30 minutes at Weeks 0, 4, and 8. The recommended maintenance dosage is 200 mg administered by subcutaneous injection (given as two consecutive injections of 100 mg each) at Week 12, and every 4 weeks thereafter. Lilly received approval for Omvoh in Japan and the European Union earlier in 2023.

FDA approves LOQTORZI™ (toripalimab-tpzi)

by

On October 27, 2023, Coherus BioSciences, Inc. and Shanghai Junshi Biosciences Co., Ltd. announced that the U.S. Food and Drug Administration approved LOQTORZI™ (toripalimab-tpzi) in combination with cisplatin and gemcitabine for the first-line treatment of adults with metastatic or recurrent locally advanced nasopharyngeal carcinoma (NPC), and as monotherapy for the treatment of adults with recurrent, unresectable, or metastatic NPC with disease progression on or after platinum-containing chemotherapy.

Toripalimab (marketed as Tuoyi® in China) is an IgG4k anti-PD-1 monoclonal antibody developed by Shanghai Junshi Bioscience Co., Ltd. Coherus partnered with the company to co-develop toripalimab, with Coherus responsible for the development and commercialization of toripalimab in the US and Canada. In 2018, toripalimab became the first anti-PD1 approved in China, and the product is now approved there for multiple types of cancer.

Toripalimab was granted Orphan Drug designations by the FDA for the treatment of NPC, mucosal melanoma, soft tissue sarcoma, esophageal cancer, and SCLC. FDA also granted Breakthrough Therapy designation to toripalimab for the treatment of recurrent or metastatic NPC with disease progression on or after platinum-containing chemotherapy and in combination with gemcitabine and cisplatin as a first-line treatment for patients with recurrent or metastatic NPC.

FDA’s approval was based on results of the JUPITER-02 Phase 3 study and the POLARIS-02 Phase 2 study and is irrespective of a patient’s PD-L1 status. The recommended LOQTORZI dose with cisplatin and gemcitabine is 240 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months. The recommended LOQTORZI dose as a single agent for previously treated NPC is 3 mg/kg every two weeks until disease progression or unacceptable toxicity.

The Phase 3 JUPITER-02 (NCT03581786) study included patients with recurrent or metastatic NPC and no previous chemotherapy for recurrent or metastatic disease. Patients (n=289)  were randomized (1:1) to receive either toripalimab (240 mg) or placebo in combination with gemcitabine-cisplatin therapy every 3 weeks for up to six cycles, followed by monotherapy with toripalimab or placebo. The primary endpoint was PFS as assessed by a blinded independent review committee according to RECIST v.1.1. The combination of toripalimab and gemcitabine-cisplatin improved the median progression-free survival compared to the chemotherapy arm (11.7 vs 8 months, respectively), the overall response rate (77.4% vs. 66.4% (P = 0.033), respectively) and the median duration of response (10.0 vs. 5.7 months, respectively).

In the POLARIS-02 clinical study, LOQTORZI demonstrated durable antitumor activity in patients with recurrent or metastatic NPC who failed previous chemotherapy, with an objective response rate (ORR) of 20.5%, a disease control rate (DCR) of 40.0%, and a median OS of 17.4 months with an acceptable safety profile.

FDA approves Bimzelx (bimekizumab-bkzx)

by

On October 18, 2023, the US Food and Drug Administration approved Bimzelx (bimekizumab-bkzx) for the treatment of moderate to severe plaque psoriasis  in adults who are candidates for systemic therapy or phototherapy. [1] Bimekizumab is a humanized IgG1 kappa antibody that selectively inhibits IL-17A and IL-17F by binding regions that are common to these pro-inflammatory cytokines, which share ~50% sequence identity and are expressed as homodimers and IL-17A/F heterodimers. Bimekizumab is approved at a recommended dose of 320 mg, administered by two subcutaneous injections of 160 mg each every four weeks to week 16 and every eight weeks thereafter.

The approval of bimekizumab is supported by data from two Phase 3 studies that compared the effects of bimekizumab to those of either ustekinumab (Stellara®; BE VIVID study; NCT03370133) or adalimumab (Humira®; BE SURE study; NCT03412747) in adults with moderate to severe plaque psoriasis. These pivotal studies met their co-primary endpoints at Week 16, demonstrating superiority of bimekizumab over the active comparator in certain defined measures (e.g., Psoriasis Area and Severity Index). Clinical responses achieved with bimekizumab at Week 16 were maintained up to one year. [2-3] Coprimary endpoints were also met in the Phase 3 BE READY study (NCT03410992), which investigated the efficacy and safety of bimekizumab in patients with moderate to severe plaque psoriasis compared to placebo.

Trends in the commercial development of antibody therapeutics: Focus on the early-stage pipeline

Tuesday October 24th, 11am ET/4pm BST/5pm CET

Speaker: Silvia Crescioli, PhD (The Antibody Society)

Need insights into the early-stage antibody therapeutics pipeline? We’ve got you covered! Join us Tuesday Oct 24th for an in-depth analysis of the early-stage pipeline stratified by cancer and non-cancer indications, revealing trends in the molecular formats, targets, and mechanism of action.

Abstract: Since 2014, the number of antibody therapeutics entering clinical development annually has increased steadily, from 71 in 2014 to 286 in 2022. This has resulted in a clinical pipeline currently composed of ~1250 molecules, of which ~1100 and ~150 molecules are in early- and late-stage development, respectively. Despite the great interest in trends in early-stage clinical development, due to the difference in scale and difficulty in tracking molecules newly entered in clinical studies, analyses of trends in the global commercial development of antibody therapeutics are often limited to the late-stage clinical pipeline only. Luckily, The Antibody Society meticulously collects data for antibody therapeutics at all stages of clinical development. This webinar will provide an exhaustive analysis of the early-stage pipeline stratified by cancer and non-cancer indications, revealing trends in the molecular formats, targets, and mechanism of action.
