“Antibodies to Watch in 2020” at PEGS Europe

November 25, 2019 by The Antibody Society

Over the past decade, the ‘Antibodies to Watch’ article series has documented the results of the global biopharmaceutical industry’s efforts to bring innovative antibody therapeutics to patients in need. Dr. Janice Reichert, Executive Director of The Antibody Society, offered a preview of the 2020 version on Wednesday November 20, 2019 during the ‘Developing Successful Antibody Products’ session at PEGS Europe.

‘Antibodies to watch in 2020’ includes updates on recent and anticipated events relevant to antibody therapeutics in clinical development. Data for antibody therapeutics that were first approved in either the US or EU during 2019, as well as several products first approved in Russia or India, were provided. Antibody therapeutics undergoing regulatory review by the Food and Drug Administration or the European Medicines Agency as of November 2019 were also discussed. Brief summaries of antibody therapeutics in late-stage clinical study that may progress to regulatory review in late 2019 or 2020, based on public disclosures by the sponsoring companies, were included. In concluding, Dr. Reichert noted that the late-stage clinical pipeline is robust, and she anticipated that more antibody therapeutics will be in late-stage studies in 2020 than any year previously documented. Remarkably, compared to 2010, the number of antibody therapeutics currently in late-stage studies has nearly tripled (to 75 antibody therapeutics).

FDA approves brolucizumab-dbll (BEOVU®)

October 11, 2019 by Janice Reichert

On October 7, 2019, the US Food and Drug Administration (FDA) approved brolucizumab-dbll (BEOVU®) for the treatment of neovascular age-related macular degeneration (nAMD). Brolucizumab is a humanized antibody single-chain variable fragment that binds to the 3 major isoforms of human vascular endothelial growth factor (VEGF), thereby interfering with their interaction with receptors VEGFR-1 and VEGFR-2 and suppressing endothelial cell proliferation, neovascularization and vascular permeability. BEOVU is administered by intravitreal injection, and the recommended dose is 6 mg monthly for the first three doses, followed by one dose of 6 mg every 8-12 weeks. A marketing application for brolucizumab is undergoing review by EMA.

FDA’s approval was based on data from two Phase 3 studies, HAWK (NCT02307682) and HARRIER (NCT02434328), comparing the efficacy and safety of intravitreal injections of brolucizumab versus aflibercept in nAMD. Brolucizumab met the primary efficacy endpoint of non-inferiority to aflibercept (EYLEA®) in mean change in best-corrected visual acuity (BCVA) at week 48 in both trials, with a mean change in BCVA of 6.6 letters for brolucizumab 6 mg versus 6.8 letters for aflibercept in HAWK trial and 6.9 letters versus 7.6 letters, respectively, in the HARRIER study. Additionally, at week 48, brolucizumab was superior to aflibercept in secondary endpoints considered key parameters of the disease, such as central subfield retinal thickness and retinal fluid (intraretinal fluid and/or subretinal fluid). Results at 96 weeks reaffirmed the superiority of brolucizumab 6 mg in reduction of retinal fluid, and patients who received this dose continued to demonstrate reductions in central subfield thickness.

New antibody-drug conjugate approved in the US

June 10, 2019 by Janice Reichert

On June 10, 2019, the U.S. Food and Drug Administration (FDA) granted accelerated approval to Polivy (polatuzumab vedotin-piiq), in combination with the chemotherapy bendamustine and a rituximab product (BR), to treat adult patients with diffuse large B-cell lymphoma (DLBCL) that has progressed or returned after at least two prior therapies. Polivy is composed of a humanized anti-CD79b IgG1 antibody conjugated to the antimitotic agent monomethyl auristatin E (MMAE). The antibody’s target is highly expressed on B cells of patients with lymphoma. The biologics license application for Polivy was granted FDA’s Breakthrough Therapy and priority review designations. The drug also has European Medicines Agency (EMA)’s PRIME designation, and US and EU Orphan Drug designations for DLBCL. EMA is reviewing a marketing authorization application for Polivy.

The drug’s efficacy was evaluated in a study of 80 patients with relapsed or refractory DLBCL who were randomized to receive Polivy with BR or BR alone. Efficacy was based on complete response rate and duration of response (DOR), defined as the time the disease stays in remission. At the end of treatment, the complete response rate was 40% with Polivy plus BR compared to 18% with BR alone. Of the 25 patients who achieved a partial or complete response to Polivy plus BR, 16 (64%) had a DOR of at least six months and 12 (48%) had a DOR of at least 12 months.

Anti-IL17 netakimab registered in Russia

May 11, 2019 by Janice Reichert

On May 7, 2019, BIOCAD announced the registration of netakimab (Efleira®, BCD-085) in Russia for the treatment of moderate to severe plaque psoriasis. Netakimab is a humanized IgG1 monoclonal antibody (mAb) in which the VH domain is replaced by a Lama glama VHH domain possessing a long complementarity-determining region (CDR-H3).  The mAb targets interleukin (IL)-17, a pro-inflammatory cytokine that plays a critical role in the pathogenesis of psoriasis. The registration is the first for an innovative mAb developed in Russia.

The efficacy and safety of Efleira® in psoriasis patients was confirmed in the Phase 3 BCD-085-7/PLANETA study (NCT03390101), which was conducted in 22 certified study sites in Russia and 2 study sites in the Republic of Belarus. After 12 weeks of the treatment, 83.3% of patients who received netakimab once a month after induction for the first 3 weeks achieved a 75% improvement in Psoriasis Area and Severity Index. The total duration of therapy and follow-up in this study is 3 years.

BIOCAD, which is based in Moscow, is planning to start a pivotal clinical trial of netakimab in psoriasis in Europe later in 2019.

Risankizumab-rzaa granted FDA approval

April 24, 2019 by Janice Reichert

On April 23, 2019, the US Food and Drug Administration approved risankizumab-rzaa (SKYRIZI™) for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. Risankizumab is a humanized IgG1 monoclonal antibody that inhibits interleukin (IL)-23, a cytokine involved in inflammatory processes, by binding to its p19 subunit. SKYRIZI is part of a collaboration between Boehringer Ingelheim and AbbVie, with AbbVie leading development and commercialization of SKYRIZI globally.

The product’s approval is supported by data from four randomized, placebo and/or active-controlled pivotal studies, ultIMMA-1, ultIMMa-2, IMMhance and IMMvent, that evaluated the safety and efficacy of risankizumab in more than 2,000 patients with moderate-to-severe chronic plaque psoriasis. The co-primary endpoints of the studies were Psoriasis Area and Severity Index and static Physician Global Assessment [sPGA] score of clear or almost clear [sPGA 0/1] at 16 weeks versus placebo. In these four studies, all co-primary and ranked secondary outcome measures were met and no new safety signals were observed. Results of the UltIMMa-1 (NCT02684370) and UltIMMa-2 (NCT02684357) studies were reported in The Lancet. Risankizumab was previously approved in Japan and Canada, and a marketing authorization application for risankizumab is currently undergoing regulatory review in the European Union.
