LTGO-33 is a state-independent NaV1.8 inhibitor with over 600-fold selectivity for the NaV1.8 channel over other sodium channels. Chronic pain affects millions, and existing treatments offer limited efficacy, risk of abuse, and low tolerability. There is an urgent need for new drugs that target validated pain mechanisms such as NaV1.8, which has recently gained increased attention. This article explores the unique pharmacological properties of LTGO-33, setting it apart from earlier NaV1.8 inhibitors.

STC15 is Storm Therapeutics' first-in-class and first-to-clinic inhibitor of the post-transcriptional RNA modifier, METTL3, which progressed from HTS hit to clinical development in less than three years.

One of the key challenges in CNS projects is achieving sufficient unbound brain exposure to engage the target. To predict CNS exposure, scientists employ metrics like CNS MPO scores from Pfizer and Merck, Bayesian models, and methods for balancing physicochemical properties. However, these in silico metrics often fail to correlate well with experimental data. Schrödinger's team has discovered the energy of solvation (E-sol) metric, which accurately predicts Kp,uu and has been validated with CNS-penetrant DLK inhibitors. Explore more in this detailed Drug Hunter article.

Novartis’ HRO761 is an oral allosteric WRN helicase inhibitor, aimed at treating MSI-high and dMMR tumors. This article details the discovery of HRO761 and highlights the importance of selecting appropriate assays during early HTS as well as transferable medicinal chemistry strategies to optimize permeability and solubility through the modulation of LipE, neutral TPSA, chameleonicity, and non-classical zwitterions. It also explores the X-ray structure of HRO761 bound to WRN, how it differentiates from Vividion's VVD-214, its preclinical activity, clinical status, chemical synthesis, and more!

In June, we saw several FDA approvals for treatments targeting primary biliary cholangitis and COPD. The industry witnessed multibillion- and multimillion-dollar deals across various therapeutic areas. Advances were made in obesity therapeutics, with novel targets and clinical readouts for GLP-1 agonists and NLRP3 inhibitors. Alkermes and Takeda reported results for OX2R agonists in narcolepsy, while an antimalarial drug showed promise in PCOS. Despite these advancements, there were clinical trial failures for key molecules. Here's a recap of the most notable news highlights from June 2024!

Bexotegrast is a dual-selective αvβ6-αvβ1 integrin inhibitor with surprising efficacy and safety data from a Ph. II trial in idiopathic pulmonary fibrosis (IPF). The αv integrins have been studied for decades in indications such as cancer and IPF. Both small molecule and antibody-based integrin inhibitors have demonstrated preclinical toxicities in non-human primates. This article highlights the unmet need for effective therapies for IPF and related conditions, a comparison of bexotegrast with other integrin binders, and possible reasons why bexotegrast is different in terms of safety.
