FDA approves Leqembi (lecanemab-irmb) for the treatment of Alzheimer’s disease

January 6, 2023 by Janice Reichert

On January 6, 2023, the U.S. Food and Drug Administration approved Leqembi (lecanemab-irmb) via the Accelerated Approval pathway for the treatment of Alzheimer’s disease. The labeling states that treatment with Leqembi should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was studied in clinical trials. The approved dose of lecanemab is 10 milligram/kilogram every two weeks.

Lecanemab (BAN2401) is a humanized anti-amyloid beta protofibril IgG1k antibody initially developed by BioArctic Neuroscience. BAN2401 was licensed to Eisai in a collaboration agreement, allowing the jointly development of lecanemab as a treatment for Alzheimer disease (AD). Under an agreement with Biogen, Eisai and Biogen co-commercialize and co-promote lecanemab.

The accelerated approval was supported by data from Study 201 (NCT01767311), which assessed the clinical efficacy of lecanemab at multiple doses (2.5 mg/kg biweekly, 5 mg/kg monthly, 5 mg/kg biweekly, 10 mg/kg monthly, 10 mg/kg biweekly) or placebo and explored the dose response of lecanemab using a composite clinical score (ADCOMS) in 856 patients with mild cognitive impairment due to AD and mild AD with confirmed presence of amyloid pathology. Patients receiving the treatment had significant dose- and time-dependent reduction of amyloid beta plaque, with patients receiving the approved dose of lecanemab, 10 milligram/kilogram every two weeks, having a statistically significant reduction in brain amyloid plaque from baseline to Week 79 compared to the placebo arm, which had no reduction of amyloid beta plaque.

Lecanemab is also being evaluated in the Clarity AD Phase 3 study (NCT03887455), which is designed to evaluate the efficacy, long-term safety, and tolerability of 10 mg/kg IV lecanemab administered every 2 weeks in 1795 patients with early AD. The primary outcome measurement was the change from baseline in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) at 18 months of treatment. In September 2022, Eisai Co and Biogen Inc announced positive topline results from Clarity AD Phase 3 trial where lecanemab met the primary endpoint by reducing by 27% the clinical decline on the CDR-SB compared with placebo at 18 months. All key secondary endpoints were also met. Based on results of the study, Eisai may file for traditional approval in the US and for marketing authorization applications in Japan and Europe.

Therapeutic Opportunities in Glycoscience: Bioorthogonal chemistry in translation

December 29, 2022 by Janice Reichert

Lecture summary written by Czeslaw Radziejewski, PhD.

Antibody Engineering & Therapeutics, held in December 2022, offered many opportunities to hear exciting and informative presentations by experts in the field, including Carolyn Bertozzi, Professor of Chemistry at Stanford University and 2022 Nobel prize laureate in Chemistry.

In her plenary lecture, Therapeutic Opportunities in Glycoscience: Bioorthogonal chemistry in translation, Prof. Bertozzi presented a retrospective of her remarkable contributions to chemical biology. She almost singlehandedly created the field of bioorthogonal chemistry, which is now used in the development of human biotherapeutics. Since its inception, bioorthogonal chemistry has had enormous scientific impact by enabling mechanisms to address a wide variety of biological questions.

Prof. Bertozzi was trained in traditional synthetic organic chemistry, but rapid advancements in biology inspired her to consider how chemical reactions might be reliably controlled within organisms. She started with the idea of performing chemical reactions in live cells. In contrast to organic synthesis, which is generally executed in organic solvents, often at high temperatures, chemistry done in live cells must occur in water at a pH close to physiological, at temperatures close to 37oC, and generally away from equilibrium. Carrying out reactions in living organisms is additionally complicated because the molecules used in-vivo cannot be toxic and cannot be metabolized faster than the reaction rate with a biological target. For such chemistry, Bertozzi coined the name and formulated the concept of bioorthogonal chemistry, which is chemistry that does not interact or interfere with a biological system. Bioorthogonal reagents and reactions must not have counterparts in biological systems. [1]

Prof. Bertozzi’s research focused on glycans, which are complex polysaccharides that decorate the surface of every mammalian cell. Notably, the structure and composition of glycans displayed on the cell surface undergo alterations in response to the physiological state of an organism. In normal cells, oligosaccharide structures terminate with the sialic acid, but it has been known since the 1960s that the glycosylation pattern on cancer cells is dramatically different from normal cells. Cancer cells tend to have a much higher abundance of sialic acids, which are attached to different sugars and in different linkages than in healthy cells. This difference in glycosylation architecture could potentially be exploited for imaging glycosylation using bioorthogonal chemistry. To begin with, the oligosaccharides would have to be labeled with a bioorthogonal sugar derivative bearing a functional group. In the next step, the functional group on the incorporated unnatural sugar would react with a bioorthogonal, detectable probe molecule. The early idea for a molecule that could be metabolically incorporated in place of sialic acid came from the work of a German carbohydrate chemist, Werner Reutter, who reported that N-acetyl-modified mannosamine could be used by cells as a precursor of side-chain modified sialic acid. Based on this observation, Bertozzi’s conceived the idea that the methyl group in the N-acetyl group could be appended with azide functionality. Then, a reactive, abiotic molecule could serve as the probe. Nucleophilic azide can enter a reaction called Staudinger reduction with triphenylphosphine, but this reaction results in azide reduction to a primary amine. However, when one of the phenyl rings was modified with an ester leaving group, hydrolysis of the transition product (azo-ylide) resulted in a stable linkage of the phosphine to sialic acid. The stable coupling of phosphine to azide group on a sugar moiety is known as Staudinger ligation.

Ublituximab approved by FDA for multiple sclerosis

December 28, 2022 by Janice Reichert

On December 28, 2022, the U.S. Food and Drug Administration approved BRIUMVI™ (ublituximab-xiiy), for the treatment of relapsing forms of multiple sclerosis (RMS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults. [1]

Ublituximab (TG-1101) is a chimeric anti-CD20 IgG1k antibody glycoengineered for enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) that was originally developed by LFB Biotechnology and licensed to TG Therapeutics as a treatment for CLL and multiple sclerosis (MS).

The approval was based on results of the randomized, double-blinded, active-controlled Phase 3 trials ULTIMATE I (NCT03277261) and ULTIMATE II (NCT03277248) evaluating ublituximab (450 mg dose IV every 6 months, following a Day 1 infusion of 150 mg over four hours and a Day 15 infusion over one hour) compared to teriflunomide (14 mg oral tablets taken once daily) in a total of 1,094 patients with relapsing MS for both studies. The primary endpoint was the annualized relapse rate (ARR). Results from the ULTIMATE I and II Phase 3 trials showed that the primary endpoint was met, with a significant reduction of the ARR for ublituximab vs. teriflunomide over a period of 96 weeks. [2]

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.

Registration is open!
