The sparsity of mid-to-late stage prospects in atopic dermatitis (AD, or eczema) – which has proved an especially challenging indication – plus some newsmaking fizzles in the space have caused developers to probe new targets with particular intensity. Most popular approaches thus far involve IL-4, IL-13, thymic stromal lymphopoietin and JAK. Developers have stumbled for varying reasons such as high placebo response rates, safety or lack of clinical proof of concept. Among the potential AD rescuers is Nektar Therapeutics Inc. with rezpegaldesleukin (rezpeg), which takes aim at IL-2.
As developers continue to search for better amyotrophic lateral sclerosis (ALS) therapies, Neurosense Therapeutics Ltd. turned up some hopeful findings from its phase IIb Paradigm trial with PrimeC. The drug, a combination therapy (ciprofloxacin and celecoxib) designed to target multiple ALS pathways, is having salutary effects on microRNA modulation (miRNA), Neurosense said, with the study showing a “profound and consistent” downregulation of 161 mature miRNAs across all time points in the double-blind period of the experiment.
Cartesian Therapeutics Inc. followed up December’s phase IIb data with more good news regarding Descartes-08, offering 12-month efficacy and safety results that whetted Wall Street’s appetite for the phase III Aurora effort ahead. Milos Miljkovic, chief medical officer, told BioWorld that minimum symptom expression – among the areas where Descartes-08 shone, providing relief for “months and months after the last dose of treatment” – is especially important to patients.
Rhythm Pharmaceuticals Inc.’s sales with Imcivree (setmelanotide) in weight management could exceed $1 billion by 2028 if hypothalamic obesity (HO) is added to the label of the drug, Oppenheimer analyst Leland Gershell said in a report. Boston-based Rhythm rolled out positive top-line data from the pivotal phase III study called Transcend with the melanocortin-4 receptor agonist in HO. The global trial met its primary endpoint with a statistically significant and highly clinically meaningful reduction in body mass index in adult and pediatric HO patients vs. placebo.
Last October, having chalked another trial failure with E-selectin antagonist uproleselan, Glycomimetics Inc. made known its acquisition plan for privately held, solid tumor-focused Crescent Biopharma Inc. – backed by $200 million from a syndicate of investors who liked the odds of success with CR-001, a preclinical VEGFxPD-1 bispecific antibody.
Aldeyra Therapeutics Inc. is hoping that research already underway will satisfy the U.S. FDA, which delivered to the company another complete response letter (CRL) related to the NDA for reproxalap in dry eye disease (DED).
Greenwich Lifesciences Inc. followed a February update with another on the phase III Flamingo-01 trial, providing open-label immune response data for GLSI-100, a HER2/neu peptide vaccine immunotherapy to prevent breast cancer recurrences in patients who have completed standard therapy. Specifically, GLSI-100 combines GP2, the HER2/neu-derived peptide, with granulocyte-macrophage colony-stimulating factor.
GRI Bio Inc.’s oral version of tazarotene is showing phase IIa promise in idiopathic pulmonary fibrosis (IPF). The peek at interim safety with the compound, a RAR-βɣ dual agonist designed to inhibit the activity of human type 1 invariant natural killer T cells, consisted of a preplanned analysis of two-week results in the biomarker study. GRI-0621 at 4.5 mg once daily proved safe and well-tolerated in the first 12 patients.
Vaxcyte Inc. characterized its latest phase II data with VAX-24 as positive but Wall Street wasn’t so sure about the dose-finding outcomes with the 24-valent pneumococcal conjugate vaccine (PCV), and shares of the San Carlos, Calif.-based firm (NASDAQ:PCVX) closed March 31 at $37.76, down $31.70, or 46%.
Bispecific antibodies have gotten plenty of press in recent years, but less prominent in headlines are bifunctional ones – i.e., those that boast one binding site for an antigen and another site for a non-antibody molecule such as a toxin or drug, taking aim at a single target and bringing a secondary function for extra oomph.
