FDA approved Izervay, a complement C5 inhibitor, for the treatment of geographic atrophy secondary to age-related macular degeneration, according to a press release from Astellas Pharma.

The approval was based on the data from the GATHER1 and GATHER2 phase 3 clinical trials in which monthly 2 mg injections of Izervay (avacincaptad pegol intravitreal solution) showed a statistically significant reduction (P < .01) in the rate of geographic atrophy growth at 12 months. The slowing in disease progression was seen as early as 6 months, while up to a 35% reduction in progression occurred in the first year of treatment.

Talvey (talquetamab-tgvs)

FDA granted accelerated approval of Talvey (talquetamab-tgvs), a first-in-class bispecific antibody for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 antibody.

Talvey is a bispecific T-cell engaging antibody that binds to the CD3 receptor on the surface of T cells and G protein-coupled receptor class C group 5 member D (GPRC5D) expressed on the surface of multiple myeloma cells, non-malignant plasma cells and healthy tissue such as epithelial cells in keratinized tissues of the skin and tongue.

Elrexfio (elranatamab-bcmm)

FDA granted accelerated approval to elranatamab-bcmm (Elrexfio, Pfizer, Inc.), a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager, for adults with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.

Sohonos (palovarotene)

FDA approved Sohonos (palovarotene) capsules as a retinoid indicated for the reduction in volume of new heterotopic ossification in adults and pediatric patients aged 8 years and older for females and 10 years and older for males with fibrodysplasia ossificans progressiva (FOP).

The FDA approval was based on the pivotal efficacy and safety data from the Phase 3 MOVE trial, the first and largest multicenter, open-label trial in adult and pediatric patients.

Veopoz (pozelimab-bbfg)

FDA approved Veopoz (pozelimab-bbfg) for the treatment of adult and pediatric patients 1 year of age and older with CHAPLE disease, also known as CD55-deficient protein-losing enteropathy. Veopoz is the first and only treatment indicated specifically for CHAPLE. Veopoz, a fully human monoclonal antibody, is designed to target complement factor C5, a protein involved in complement system activation.

The FDA approval was based on results from a Phase 2/3 open-label trial that investigated the efficacy and safety of pozelimab in 10 patients aged 3 to 19 (median of 8.5 years).

Eylea HD (aflibercept)

FDA approved EYLEA HD (aflibercept) Injection 8 mg for the treatment of patients with wet age-related macular degeneration (wAMD), diabetic macular edema (DME) and diabetic retinopathy (DR). This is the first and only treatment approved in wAMD and DME for immediate dosing at 8-week and up to 16-week intervals following three initial monthly doses

Approval was based on the pivotal PULSAR and PHOTON trials in which EYLEA HD demonstrated clinically equivalent vision gains to EYLEA (aflibercept) Injection 2 mg that were maintained with fewer injections.

Qalsody (tofersen)

Tofersen, an antisense oligonucleotide (ASO), is the first approved treatment for SOD1-ALS. In people with this form of the disease, mutations in their SOD1 gene cause their bodies to create a toxic form of SOD1 protein. This toxic protein causes motor neurons to degenerate, resulting in progressive muscle weakness. Tofersen is designed to bind to SOD1 mRNA and reduce SOD1 protein production.

In addition to the ongoing open label extension of the Phase III VALOR study, tofersen is being studied in the Phase 3 ATLAS study designed to evaluate whether tofersen can delay clinical onset when initiated in presymptomatic individuals with a SOD1 genetic mutation and biomarker evidence of disease activity. Biogen licensed tofersen from Ionis Pharmaceuticals, Inc. under a collaborative development and license agreement.

Joenja (leniolisib)

Joenja is the “first and only” oral, selective PI3Kδ inhibitor is the first and only treatment approved in the United States for APDS, a rare and progressive primary immunodeficiency. The FDA evaluated the Joenja application for APDS under Priority Review, which is granted to therapies that have the potential to provide significant improvements in the treatment, diagnosis or prevention of serious conditions.

Approval was based on findings from a multinational, triple-blind, placebo-controlled, randomized Phase II/III clinical trial, which evaluated efficacy and safety in 31 patients diagnosed with APDS aged 12 years and older. Also submitted as part of the application were data from a long-term, open-label extension clinical trial in which 38 patients received Joenja for a median of two years.

Rezzayo (rezafungin)

Rezzayo is an echinocandin antifungal indicated in patients who have limited or no alternative options for the treatment of candidemia and invasive candidiasis. Approval of this indication is based on limited clinical safety and efficacy data for Rezzayo. The FDA has approved Rezzayo as a once-weekly antifungal to treat invasive candidiasis and candidemia.

Last year, Melinta announced that it had acquired the exclusive rights to commercialize Rezzayo in the U.S. from Cidara. Cidara retains the rights to rezafungin in Japan and has licensed the commercial rights to Melinta Therapeutics in the U.S. and Mundipharma in all other geographies. The European Medicines Agency (EMA) accepted the marketing authorization application (MAA) for rezafungin in August 2022 and it is currently under review.

Zynyz (Retifanlimab-Dlwr)

Zynyz (retifanlimab-dlwr), a humanized monoclonal antibody targeting programmed death receptor-1 (PD-1), is FFDA approved for the treatment of adults with metastatic or recurrent locally advanced Merkel cell carcinoma (MCC). The Biologics License Application (BLA) for Zynyz for this indication has been approved under accelerated approval by the U.S. FDA based on tumor response rate and duration of response (DOR). Continued approval of Zynyz for this indication may be contingent on verification and description of clinical benefit in confirmatory trials.

The FDA approval was based on data from the POD1UM-201 trial, an open-label, multiregional, single-arm study that evaluated Zynyz in adults with metastatic or recurrent locally advanced MCC who had not received prior systemic therapy for their advanced disease. Among chemotherapy-naïve patients (n=65), Zynyz monotherapy resulted in an objective response rate (ORR) of 52% (95% confidence interval [CI]: 40-65) as determined by independent central review (ICR) using RECIST v1.1. Complete response was seen in 12 patients (18%), and 22 patients (34%) showed partial response. Among the responding patients, the duration of response (DOR) ranged from 1.1 to 24.9+ months, and 76% (26/34) experienced a DOR of six months or longer, and 62% (21/34) experienced a DOR of 12 months or longer by landmark analysis.

Daybue (trofinetide)

Daybue is the “first and only” FDA approved treatment for Rett syndrome in adults and children 2 years of age and older. Trofinetide is a synthetic version of a naturally occurring molecule known as the tripeptide glycine-proline-glutamate (GPE). The mechanism by which trofinetide exerts therapeutic effects in patients with Rett syndrome is unknown.

The FDA approval of DAYBUE was supported by results from the pivotal Phase 3 LAVENDER study evaluating the efficacy and safety of trofinetide versus placebo in 187 female patients with Rett syndrome five to 20 years of age. In the study, treatment with DAYBUE demonstrated statistically significant improvement compared to placebo on both co-primary efficacy endpoints, as measured by the change from baseline in Rett Syndrome Behaviour Questionnaire (RSBQ) total score (p=0.018) and the Clinical Global Impression-Improvement (CGI-I) scale score (p=0.003) at week 12.

In 2018, Acadia entered into an exclusive license agreement with Neuren Pharmaceuticals Limited for the development and commercialization of trofinetide for the treatment of Rett syndrome and other indications in North America.

Zavzpret (zavegepant)

Zavzpret, is the “first and only” calcitonin gene-related peptide receptor antagonist nasal spray for treating migraines with or without an aura, or sensory disturbances such as flashes of light that can accompany a migraine.

Zavzpret began working to treat migraine symptoms in as little as 30 minutes and provided some relief for up to 48 hours after the last administered dose. A 10mg dose of the drug proved more effective than a placebo at relieving pain and other migraine symptoms.

Approval was based on the pivotal Phase III study, Zavzpret was statistically superior to placebo on the co-primary endpoints of pain freedom and freedom from most bothersome symptom at two hours post-dose. The pivotal study also demonstrated pain relief as early as 15 minutes in a prespecified secondary endpoint versus placebo.

Imjudo (tremelimumab)

AstraZeneca’s Imjudo (tremelimumab) was approved by FDA in combination with Imfinzi (durvalumab) for treating unresectable liver cancer. HCC is the most common type of liver cancer.

Imjudo (tremelimumab) is a human monoclonal antibody that targets the activity of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). Imjudo blocks the activity of CTLA-4, contributing to T-cell activation, priming the immune response to cancer and fostering cancer cell death.

The approval was based on positive results from a Phase III trial (HIMALAYA), which demonstrated that patients treated with the combination of Imjudo and Imfinzi experienced a 22% reduction in the risk of death compared to sorafenib, an oral kinase inhibitor used to treat late-stage liver cancer. The results of the Phase III trial also showed evidence that the combination therapy allowed an estimated 31% of patients to live three years after administration, compared to 20% of sorafenib-treated patients, who showed the same longevity.

Beyond HIMALAYA, Imjudo is being tested in combination with Imfinzi across multiple tumour types including locoregional HCC (EMERALD-3), SCLC (ADRIATIC) and bladder cancer (VOLGA and NILE).

Imjudo is also under review by global regulatory authorities in combination with Imfinzi and chemotherapy in 1st-line metastatic NSCLC based on the results of the POSEIDON Phase III trial, which showed the addition of a short course of Imjudo to Imfinzi plus chemotherapy improved both overall and progression-free survival compared to chemotherapy alone.

Tecvayli (teclistamab-cqyv)

Janssen’s Tecvayli (teclistamab-cqyv) is a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager indicated for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 monoclonal antibody.

  • Multiple myeloma is a cancer of the plasma cells in the bone marrow. Plasma cells normally make antibodies which fight infection, but when the plasma cells become malignant and develop into multiple myeloma, the myeloma cells proliferate and replace normal cells in the bone marrow.
  • Tecvayli targets both BCMA (B-cell maturation antigen) and CD3, the T-cell receptor. BCMA is expressed at high levels on multiple myeloma cells. Tecvayli works by redirecting CD3-positive T-cells to BCMA-expressing myeloma cells to induce the killing of the cancer cells.
  • Warnings and precautions associated with Tecvayli include hepatotoxicity, infections, neutropenia, hypersensitivity and other administration reactions, and embryo-fetal toxicity.
  • Common adverse reactions observed in clinical trials include cytokine release syndrome, neutropenia, and anemia. Infections were frequent with the most common being upper respiratory tract infections and pneumonia. Hypogammaglobinemia and neurotoxic events were also observed in some patients.
