The microbiome and a frontline innate antimicrobial sensor, Toll-like receptor 5 (TLR5), play an essential role in the development of idiopathic pulmonary fibrosis (IPF). A scientific collaboration led by researchers at the National Institute of Environmental Health Sciences has revealed how TLR5 protects against fibrosis through its ability to modulate the lung microbiome. Their study also shows that activating TLR5 protects against fibrosis and corrects pulmonary dysbiosis.

Chinese biotech Longbio Pharma Co. Ltd. announced its IPO on the Hong Kong Stock Exchange to raise HK$1.362 billion (US$174 million) to progress its lead candidate, LP-003, a next-generation anti-IgE antibody.

Multiple updates on TROP2-directed antibody-drug conjugates (ADCs) for lung and breast cancers highlight both progress made and opportunities for improvement for the targeted class of cancer therapeutics.

Recent findings are reshaping current understanding of the post-infection landscape of SARS-CoV-2. Although previous studies had already suggested that autoimmunity might underlie the persistent neurological symptoms seen in long COVID, researchers at Yale University and Mount Sinai now reinforce this hypothesis. SARS-CoV-2 infection appears to trigger an autoimmune mechanism that drives chronic pain, fatigue and cognitive impairment in some patients.

Oorja Bio Inc., named after the phonetic spelling of “energy” in Sanskrit, secured $30 million from founding investor Westlake Biopartners in a series A financing round to advance its in-licensing approach to develop drugs for idiopathic pulmonary fibrosis (IPF) and other fibrotic and cardiopulmonary diseases.

As generic versions of its blockbuster drug Ofev (nintedanib) start to hit the market, Boehringer Ingelheim GmbH looks to have swerved the patent cliff, with European and Japanese regulators both approving a potential replacement, Jascayd (nerandomilast), this week. At its monthly meeting, the EMA’s Committee for Medicinal Products for Human Use also recommended Novartis AG’s Vijoice (alpelisib) be given conditional approval in the treatment of PIK3CA-related overgrowth spectrum disorders.

Infex Therapeutics Ltd. has published positive phase IIa data for its lead program, RESP-X, in the treatment of exacerbations of chronic respiratory infections caused by Pseudomonas aeruginosa and is now laying the ground for phase IIb development, after raising £4.3 million (US$5.8 million) in new capital.

Singapore’s Communicable Diseases Agency on May 7 said that it isolated two residents for hantavirus testing after the individuals disembarked from an Atlantic cruise ship on May 2 and May 6, respectively. The measure comes in response to the cluster of cases from the cruise ship, MV Hondius, that has resulted in three deaths so far.

Scientists at the La Jolla Institute for Immunology have identified and characterized human antibodies that neutralize the measles virus by blocking its entry into the cell. This is the first time that antibodies have been shown to bind effectively to two essential viral proteins, creating a dual blockade that prevents infection. Unlike the current vaccine, which is based on an attenuated virus and is not recommended for immunocompromised individuals, these monoclonal antibodies could be used both as a new vaccine approach and as a treatment for the entire population.

The memory of Merck & Co. Inc.’s $10 billion takeover last year of inhaled respiratory drug specialist Verona Pharma plc may not have been far from the minds of Wall Street speculators as Avalyn Pharma Inc. priced its IPO, selling about 16.6 million shares at the high end of the targeted range, or $18 each, to reap about $300 million. The stock (NASDAQ:AVLN) came out of the gate strong on the first day of trading and closed April 30 at $29.49, up $11.49, or 64%.
