- A federal district court ruled it no longer has jurisdiction over Vanda Pharmaceuticals' challenge to the FDA's drug review process. - Judge Amit Mehta stated that Vanda raised the same Appointments Clause arguments in the D.C. Circuit, which would have precedential effect. - The case centers on Vanda's constitutional challenge to the structure of FDA drug approvals under the Appointments Clause. - The ruling effectively shifts the legal battle from the district court to the federal appellate level.
- Vanda Pharmaceuticals Inc. (Nasdaq: VNDA) will participate in a fireside chat at the B. Riley Securities Mind, Muscle & Vision Summit in Boston, Massachusetts. - The event is scheduled for Thursday, July 16, 2026, as announced by the company on July 10, 2026. - Vanda is a global biopharmaceutical company focused on developing and commercializing innovative therapies to address high unmet medical needs.
- The FDA granted Rare Pediatric Disease Designation to Vanda's VCA-894A, an investigational antisense oligonucleotide targeting Charcot-Marie-Tooth disease type 2S (CMT2S). - CMT2S is a rare inherited neuromuscular disorder with an estimated prevalence of less than 1 in 1,000,000 worldwide, causing progressive sensory and motor impairment that can lead to loss of ambulation. - VCA-894A is a personalized therapy targeting a unique cryptic splice site variant within the IGHMBP2 gene not yet observed in any other patient. - If VCA-894A meets all statutory requirements and gains approval, Vanda may become eligible to receive a priority review voucher under the Rare Pediatric Disease Priority Review Voucher program.
- Vanda Pharmaceuticals has launched the Thetis study, a Phase 2 clinical trial evaluating NEREUS (tradipitant) for preventing vomiting in patients receiving high-dose GLP-1 receptor agonist therapies. - A previous Phase 2 study demonstrated that tradipitant reduced vomiting by 50% compared to placebo, with only 29.3% of treated patients experiencing vomiting versus 58.6% on placebo. - The trial addresses a significant clinical need as gastrointestinal side effects remain a leading cause of treatment discontinuation for GLP-1 therapies like semaglutide and tirzepatide. - Topline results from the multicenter, randomized, double-blind, placebo-controlled trial are expected by Q4 2026.
- Vanda Pharmaceuticals has submitted a Biologics License Application to the FDA for imsidolimab, a novel IL-36 receptor antagonist for treating generalized pustular psoriasis. - Phase 3 GEMINI trials demonstrated that 53% of patients achieved clear or almost clear skin at 4 weeks compared to 13% on placebo. - The company has requested priority review, which could lead to potential FDA approval as early as mid-2026 for this rare orphan disease. - Imsidolimab showed sustained efficacy over approximately 2 years with monthly maintenance dosing and demonstrated a favorable safety profile.
- The FDA has lifted a partial clinical hold on Vanda Pharmaceuticals' tradipitant for motion sickness, removing the previous 90-dose limitation after determining motion sickness is an acute condition rather than chronic. - The decision eliminates the need for an additional six-month dog toxicity study and allows Vanda to extend clinical studies of the neurokinin-1 receptor antagonist. - Tradipitant's New Drug Application remains on track for FDA review with a December 30, 2025 PDUFA date, potentially becoming the first new pharmacologic motion sickness treatment in over four decades.
- Vanda Pharmaceuticals reported positive Phase 2 results showing tradipitant, an oral NK-1 receptor antagonist, reduced vomiting by 50% in patients receiving GLP-1 therapy for obesity. - The randomized controlled trial of 116 overweight adults demonstrated that 29.3% of tradipitant-treated participants experienced vomiting compared to 58.6% on placebo when given a 1 mg semaglutide dose. - The findings address a critical unmet need as 30-50% of patients discontinue GLP-1 agonists due to gastrointestinal side effects, often before reaching therapeutic doses. - Vanda plans to advance tradipitant into Phase 3 trials in the first half of 2026 as a potential adjunct therapy in the $50+ billion global GLP-1 agonist market.
- AnaptysBio announced plans to separate into two independent public companies by year-end 2026, creating distinct investment opportunities for royalty management and drug development operations. - The royalty management company will focus on substantial revenue streams from Jemperli (dostarlimab) with GSK, which generated $482 million in first-half 2025 sales and carries peak sales guidance exceeding $2.7 billion. - The biopharma operations company will advance three immunology therapeutics including rosnilimab for autoimmune diseases, with Phase 2 ulcerative colitis data expected in late 2025. - GSK's Jemperli royalty structure provides escalating rates from 8% to 25% of net sales, with patent protection extending through 2035-2036 and multiple ongoing registrational trials.
- HETLIOZ (tasimelteon) met its primary endpoint in a multicenter, randomized, double-blind, placebo-controlled trial, showing significant improvements in sleep latency for patients with primary insomnia. - The melatonin receptor agonist demonstrated mean improvements in latency to persistent sleep of 44.9 minutes (20 mg dose) and 46.3 minutes (50 mg dose) versus 28.2 minutes for placebo (p < 0.001). - The drug showed sustained efficacy through follow-up time points and was not associated with cognitive or mood changes, rebound, or withdrawal effects after discontinuation. - Vanda Pharmaceuticals continues to pursue FDA approval for HETLIOZ in insomnia treatment, addressing a condition that affects over 10% of the American population.
- The FDA has granted Orphan Drug Designation to VGT-1849B, a selective peptide nucleic acid-based JAK2 inhibitor developed by Vanda Pharmaceuticals for treating polycythemia vera. - VGT-1849B utilizes novel OliPass Peptide Nucleic Acid (OPNA) chemistry to selectively target JAK2 mRNA, potentially offering improved safety compared to existing JAK inhibitors that affect multiple kinases. - The antisense oligonucleotide specifically addresses the JAK2 V617F mutation found in over 95% of polycythemia vera patients, with the disease affecting 44-57 per 100,000 people in the United States. - Unlike current JAK inhibitors such as Jakafi, Inrebic, Ojjaara, and Vonjo, VGT-1849B aims to avoid off-target kinase effects that can lead to increased toxicity and adverse side effects.
