NaV1.8, a member of the voltage-gated sodium channel (NaV) family, is predominantly expressed in peripheral sensory neurons. Based on rodent NaV1.8 knockout and knockdown studies and a 2012 report of gain-of-function mutations in humans, NaV1.8 has been linked to nociceptive, inflammatory, and neuropathic pain, including chronic neuropathic pain. This compound roundup provides a historical recap of both preclinical and clinical NaV1.8 inhibitors that shaped the landscape for the new era of pain management we are witnessing today.

With increasingly tight timelines between bench and clinic, considering formulation strategies early on can give your program a competitive edge. This succinct formulations guide provides specific clinically-used examples of common formulations, and can help you select a formulation strategy most likely to succeed based on the properties of your compound.

The impact of small and mid-sized biotech companies has become increasingly important. The shift from large pharma dominance to a biotech-driven era of drug discovery presents challenges to the traditional model of education for emerging medicinal chemists. Industry leader Dean Brown recently highlighted challenges for modern medicinal chemists starting in biotech who face fewer mentoring opportunities and are often propelled into leadership positions sooner than their counterparts in big pharma. Here we share how our team of former industry scientists at Drug Hunter can help.

NaV1.8 has become an industry focal point in the pursuit of pain therapeutics thanks to the success of Vertex’s selective inhibitor, VX-548, in Ph. III clinical trials for acute pain and Ph. II results in diabetic peripheral neuropathy. Unlike opioid receptor modulation, NaV1.8 inhibition does not carry the same addiction risks in part due to its lack of expression in the brain. Following our recent review of the leading NaV1.8 inhibitor VX-548, this article provides more details on the history of target validation for NaV1.8 in pain and why this could be the new frontier for pain management.

January was an important month for Latigo Biotherapeutics who disclosed their preclinical small molecule NaV 1.8 inhibitor for non-opioid pain treatment that enters an increasingly competitive field led by Vertex’s VX-548. A potential first-in-class pan-PKC inhibitor currently in Ph. II/III trials for uveal melanoma and a macrocyclic peptide possessing a novel mechanism of action to treat carbapenem-resistant Acinetobacter baumannii infections also made the top ten list. Eli Lilly released details for their oral small molecule IL-17A inhibitor which was discontinued in a Ph. I clinical trial d...

Among the small molecule highlights in January’s news were a $100M+ Series A for a PARP1 + PI3Kα-focused company, clinical data with an SLC inhibitor for PKU, a 5-HT2C superagonist for seizures, and a NK1,3 dual antagonist for women’s health. A novel anti-obesity agent from phenotypic screening also made headlines, and the close of a major acquisition may bring relief to the industry. You can read about these notable scientific highlights and more below.

PF-07817883 (ibuzatrelvir) is an oral, second-generation SARS-CoV-2 M^pro inhibitor developed by Pfizer. These efforts follow the success of Pfizer's antiviral combination drug, Paxlovid, which was granted Emergency Use Authorization by the FDA for the treatment of COVID-19. PF-07817883 was granted Fast Track designation and recently completed a Ph. II clinical trial in outpatient adults with COVID-19 symptoms. This article details the discovery strategy for PF-07817883, which includes addressing metabolic soft spots identified through MetID studies, recent clinical developments, and more.

Olutasidenib, discovered by Forma Therapeutics and marketed by Rigel, is an oral, brain-penetrant, selective mIDH1 inhibitor. It was granted Orphan Drug Designation and approved in December 2022 by the FDA for adults with relapsed/refractory acute myeloid leukemia. Approval was granted based on a Ph. I/II trial showing a 35% CR+CRh rate and a favorable 25.9-month median duration. This article describes the discovery and development of olutasidenib, how it is distinct from other mIDH inhibitors, and its potential in treating gliomas.

The Drug Hunter team is piloting a new series highlighting notable disclosures in the patent literature to provide our readers a timely and scientifically flavorful synopsis of therapeutic targets being actively pursued, emerging industry breakthroughs, and fascinating chemical matter. Here we highlight 12 patents published in December 2023 that piqued our interest, and compiled a searchable table comprising key information from more than 180 additional patents of potential interest to drug hunters. If you have any suggestions on how to make this more useful, please let us know!

Momelotinib is a JAK inhibitor approved by the FDA in September 2023 for treating myelofibrosis. Last year, the molecule’s co-inventors, Andrew Wilks and Christopher Burns, gave a Drug Hunter Flash talk about the development of this drug with a fascinating mechanism of action.

In celebration of the molecule’s advancement, here we recap their brilliant story, including Wilks’ discovery of the JAK kinases and how he gave them their name, and the long, sometimes fraught journey of momelotinib through several companies before its acquisition and commercialization by GSK.

Recently, we summarized the novel small molecule drug approvals of 2023 (34/55). The remaining 21 molecular entities approved were large molecules like proteins and oligonucleotides, accounting for nearly 38% of the total approvals. Notably, seven of these large molecules have earned the prestigious Breakthrough Therapy designation, relative to the two small molecules that share this recognition. A summary of approvals for large molecule drugs, accompanied by links to FDA labels and additional information pertaining to the drug's discovery and originators, appears here.

While KRAS(G12C) has been the most readily targeted form of KRAS thanks to its reactive cysteine residue, other mutations such as KRAS(G12D) make up the majority of KRAS-mutated cancers. In this roundup, we highlight 12 inhibitors, degraders, and other molecules that reflect progress in overcoming this challenge, including some of the first clinical candidates targeting non-KRAS(G12C)-mutant tumors, and why these molecules are notable.

December 2023 was a big month for estrogen receptor (ER) degraders featuring stories from Phase III candidates vepdegestrant, camizestrant, and OP-1250 (not included here) to treat breast cancer. Unfortunately, Phase II trials of Boehringer Ingelheim’s selective ENaC inhibitor, BI 1265162, to treat CF and Phase III trials of Serono’s much anticipated BTK inhibitor, evobrutinib, to treat MS were both terminated. Additionally, preclinical candidates from Genentech and Roche, promising Phase II candidates to treat myelodysplastic syndrome and atrial fibrillation, and a Phase III candidate to trea...
