UK Approves First COVID-19 Monoclonal Antibody Treatment as AstraZeneca Reports 77% Efficacy in Prevention Trial

  • The UK's MHRA approved Ronapreve, the first monoclonal antibody therapy specifically designed to treat and prevent COVID-19, developed by Regeneron and Roche.
  • The treatment combines two monoclonal antibodies administered by injection or infusion, working by binding to the virus and preventing respiratory system entry.
  • AstraZeneca simultaneously announced that its AZD7442 antibody combination reduced COVID-19 symptom risk by 77% in a trial of 5,172 participants, with over three-quarters having comorbidities affecting vaccine response.
  • Both treatments represent significant advances for vulnerable populations who may not respond adequately to COVID-19 vaccines alone.

FDA Approves Aduhelm: First Disease-Modifying Alzheimer's Treatment in Nearly Two Decades

  • The FDA granted accelerated approval to Biogen's aducanumab (Aduhelm) as the first disease-modifying Alzheimer's treatment in nearly two decades, despite divided expert opinions on its clinical efficacy.
  • Aduhelm, priced at $56,000 annually, works by reducing amyloid plaques in the brain and will require monthly intravenous infusions with comprehensive clinical and MRI monitoring for potential adverse effects.
  • As part of the accelerated approval, Biogen must conduct a Phase 4 confirmatory trial, while experts view this approval as a potential catalyst for developing more effective Alzheimer's treatments targeting multiple pathways.

FDA Approves Monjuvi in Combination with Lenalidomide for Relapsed/Refractory DLBCL

  • The FDA has approved Monjuvi (tafasitamab-cxix) in combination with lenalidomide as the first second-line treatment for adult patients with relapsed or refractory diffuse large B-cell lymphoma who are not eligible for autologous stem cell transplant.
  • The approval was based on the Phase 2 L-MIND study, which demonstrated a 55% overall response rate with a 37% complete response rate and median duration of response of 21.7 months.
  • Approximately 10,000 patients are diagnosed annually in the United States with relapsed or refractory DLBCL who are not eligible for stem cell transplant, representing a significant unmet medical need.
  • Monjuvi is a humanized CD19-targeting monoclonal antibody that received accelerated approval and will be co-commercialized by MorphoSys and Incyte in the United States.

Pertuzumab Regimen Shows Modest Survival Benefit in HER2-Positive Early Breast Cancer

• The APHINITY trial's 6-year analysis reveals that adjuvant pertuzumab with trastuzumab plus chemotherapy improved overall survival by 0.9% in HER2-positive early breast cancer patients, though not reaching statistical significance.
• Patients with node-positive disease showed the most significant benefit from the pertuzumab regimen, with a 4.5% absolute improvement in invasive disease-free survival at 6 years compared to placebo.
• The pertuzumab combination maintained a favorable cardiac safety profile with severe cardiac events occurring in less than 1% of patients, supporting its continued use in high-risk HER2-positive early breast cancer.

China Grants Conditional Approval to Seaweed-Derived Alzheimer's Drug Oligomannate

  • Chinese regulators have granted conditional approval to Oligomannate, a seaweed-derived drug for mild to moderate Alzheimer's disease, marking the first new Alzheimer's therapy approval in nearly two decades.
  • The drug, developed by Shanghai Green Valley Pharmaceuticals, showed cognitive improvements in a Phase 3 trial of 818 patients with benefits observed as early as four weeks.
  • Unlike traditional approaches targeting brain protein buildup, Oligomannate works by modulating the gut microbiome to reduce neuroinflammation associated with Alzheimer's disease.
  • The company plans to launch a global Phase 3 trial in 2020 with sites in the United States, Europe, and Asia to seek international regulatory approval.

FDA Approves First Treatment for Primary Hemophagocytic Lymphohistiocytosis, Marking 24-Year Breakthrough

  • The FDA has approved emapalumab-lzsg (Gamifant) as the first treatment specifically indicated for primary hemophagocytic lymphohistiocytosis (HLH), an ultra-rare and life-threatening immune disorder.
  • In a pivotal phase 2/3 study of 27 patients with refractory disease, 63% demonstrated overall response and 70% proceeded to hematopoietic stem cell transplant.
  • The monoclonal antibody targets interferon gamma, representing the first significant improvement in primary HLH induction therapy in 24 years.
  • Primary HLH typically affects children within the first year of life and has a median survival of less than two months without treatment.

Novartis's Kymriah: Breakthrough CAR-T Therapy Priced at $475,000 Sparks Value Debate

  • Novartis's Kymriah, the first FDA-approved CAR-T cell therapy for pediatric acute lymphoblastic leukemia, demonstrates an impressive 83% remission rate in patients who failed traditional treatments.
  • The therapy's $475,000 price tag has ignited debate among healthcare experts, with some defending it as comparable to bone marrow transplants while others argue it's excessive despite its breakthrough status.
  • Novartis has implemented innovative value-based pricing models, including outcome-based contracts where payment is contingent upon patient response and indication-specific pricing for future approvals.

FDA Approves Two New Ustekinumab Biosimilars, Bringing Total US Biosimilar Count to 65

  • The FDA has approved Biocon's Yesintek (ustekinumab-kfce) and Celltrion's Steqeyma (ustekinumab-stba) in November and December 2024, expanding treatment options for autoimmune conditions including Crohn's disease and psoriasis.
  • Of the 65 FDA-approved biosimilars, 14 have received interchangeable designation, allowing pharmacists to substitute them for reference products without prescriber intervention, enhancing patient access to more affordable treatments.
  • The biosimilar landscape continues to evolve with products spanning five major classes: insulin, granulocyte colony-stimulating factors, monoclonal antibodies, TNF-alpha inhibitors, and VEGF inhibitors.

FDA Approves Sanofi's Multaq for Atrial Fibrillation Patients, Marking First New Treatment in Two Decades

  • The FDA has approved Sanofi's Multaq (dronedarone) to reduce cardiovascular hospitalization risk in patients with atrial fibrillation or atrial flutter, representing the first new treatment option in this therapeutic area in twenty years.
  • The approval is based on five clinical studies involving 6,300 patients, with the landmark ATHENA trial demonstrating a 24% reduction in cardiovascular hospitalization or death from any cause compared to placebo.
  • Multaq showed significant clinical benefits including a 28% reduction in total hospital days and 35% decrease in heart-related hospitalization time in atrial fibrillation patients.
  • The drug is contraindicated in patients with severe heart failure, following results from the ANDROMEDA trial that showed increased mortality risk in this population.
