Deciphera’s DCC-3116 is an oral ULK1/2 inhibitor targeting the autophagy pathway, a key mechanism of tumor survival and resistance to targeted therapy. Currently in two open-label Ph. I/II trials as a monotherapy and in combination with RTK pathway inhibitors, the structure and discovery of this first-in-class compound were recently presented at the ACS Spring 2024 meeting.

TNG462, developed by Tango Therapeutics, is a potential best-in-class, oral, protein arginine methyltransferase 5 (PRMT5) inhibitor currently in Ph. I/II clinical trial for MTAP-deleted solid tumors. TNG462 is designed to cooperatively bind to PRMT5 when complexed with its endogenous inhibitor methylthioadenosine (MTA), which accumulates in MTAP-deleted tumors. This triggers synthetic lethality in cells with an MTAP-deletion and spares healthy tissues with low MTA levels. A CNS-permeable analogue, TNG908, is also entering clinical trials for MTAP-deleted glioblastoma.

VVD-214/RO7589831 is an oral covalent, reversible, and allosteric inhibitor of WRN helicase discovered by the San Diego-based biotech Vividion Therapeutics and being developed by Roche for tumors marked by microsatellite instability and/or mismatch repair deficiency. Vividion has utilized its chemoproteomics platform to discover and develop novel treatment options for oncology targets. The structure and initial preclinical pharmacology data for VVD-214 were recently disclosed at the AACR Annual Meeting 2024 in San Diego. VVD-214 is currently being evaluated in a Ph. I trial.

Peptidic GLP-1R agonists have received significant media coverage over the past year for their astounding efficacy in several indications. While most of the recent fanfare has been related to their role in weight loss, GLP-1R agonists have been a mainstay of the type 2 diabetes treatment landscape for the past 2 decades. GLP-1R agonists have also recently shown efficacy in reducing heart disease risk and treating certain chronic kidney diseases. Here’s a recap of the March 14th, 2024, Flash Talk, from Oliver Philps.

The discovery that individuals with null mutations in the NaV1.7 exhibited pain insensitivity sparked interest in targeting NaV1.7 to potentially treat pain. Despite the potential of selectively inhibiting sodium channels like NaV1.7, NaV1.8, and NaV1.9 for pain management, developing selective inhibitors suitable for clinical use has proven challenging. This article complements our coverage of VX-548, NaV1.8 as a critical target in pain management, and our NaV1.8 compound roundup and provides a reminder of noteworthy preclinical and clinical NaV1.7 small molecule inhibitors as of April 2024.

ORIC-533, a potential best-in-class oral inhibitor of CD73 from ORIC Pharmaceuticals, is currently in a Ph. Ib trial for relapsed/refractory multiple myeloma (MM). It inhibits the CD73-mediated conversion of AMP to adenosine which generates an immunosuppressive tumor microenvironment and has the potential to be a next-generation immunotherapy. The in-depth use of X-ray structures led the team to discover a novel set of phosphonate bioisosteres which acheived bioavailability in a polar scaffold. The structure and discovery of ORIC-533 were recently disclosed at the ACS Spring 2024 Meeting.

In March, Crinetics Pharmaceuticals revealed their discovery of CRN04894, a first-in-class nonpeptide melanocortin type 2 receptor (MC2R) antagonist which is currently being evaluated in several Ph. II trials. Additional molecules to make the top ten include a preclinical, brain-penetrant casein kinase 1 delta (CK1δ) inhibitor and a WT-sparing phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PI3Kα) H1047R inhibitor. Galapagos SASU and AbbVie disclosed the discovery story of their orally bioavailable cystic fibrosis transmembrane conductance regulator (CFTR) protein C2 co...

Minipigs have recently gained prominence as an alternative non-rodent in vivo model for pharmacokinetic (PK), efficacy, and toxicology studies supporting human dose predictions. This article provides an overview of the use of minipigs in small molecule preclinical drug discovery research, tracing their historical background and outlining practical considerations for selecting them in studies focusing on hepatic metabolism, oral bioavailability, CNS penetration, and toxicology. It highlights minipigs' unique advantages and makes a compelling case for their continued use in preclinical research.

The "New Drugs on the Horizon" sessions at the AACR Annual Meeting 2024 in San Diego revealed twelve innovative oncology agents and offered attendees a first look at their structures and preliminary data as they enter/progress in the clinic. In case you missed any of these exciting compounds – including selective CDK inhibitors, molecular glues, bifunctional degraders, a radiopharmaceutical, a bifunctional antibody, and an ADC – this article covers the structures and targets disclosed. A separate session disclosed the structure of a pan-RAS isoform inhibitor with remarkable clinical results.

Companies inked notable high-profile transactions in March 2024, including AbbVie's purchase of Landos Biopharma for $137.5M, AstraZeneca's $2.4B acquisition of Fusion Pharmaceuticals, and its subsequent deal to buy Amolyt for up to $1.05B. The FDA approved the first treatment for MASH. In parallel, expectations are high for the approval of Xcovery's ALK inhibitor, ensartinib. Praxis made headlines with PRAX-628, a next-generation oral NaV modulator, which showed anti-seizure efficacy in a Ph. IIa trial. Read below for more details on these and other drug discovery news stories from March 2024

We asked the global drug discovery community to nominate and vote on their favorite molecule from 2023, and the results are in. The 2023 winner, with the most votes between ten molecules, is Merck’s oral macrocyclic peptide inhibitor of PCSK9, MK-0616, derived from mRNA display technology and shown to have clinical efficacy. Herein, we highlight what makes MK-0616 so impressive to the drug discovery community.

Merck’s macrocyclic PCSK9 protein-protein interaction (PPI) inhibitor, MK-0616, is a once-daily PCSK9-lowering and LDL-cholesterol-lowering small molecule that has recently demonstrated antibody-like efficacy as an oral agent in the clinic. The program highlights numerous technical achievements at the forefront of modern drug discovery, and will set a standard for modern “classics in drug discovery” for some time.

The accelerated approvals of Ras(OFF)-targeting KRAS G12C inhibitors sotorasib and adagrasib, decades in the making, marked the beginning of a new phase of KRAS drug discovery. While an increasing number of follow-on KRAS inhibitors are emerging with similar mechanisms of action, Revolution Medicines’ 2023 Molecule of the Year Nominee, RMC-6291, is representative of a completely novel approach that could become a strong addition to the clinical toolbox for KRAS, but also serves as proof-of-concept for a new class of small molecule therapeutics entirely.

MK-1084 is an oral covalent inhibitor of KRAS(G12C) being developed by Merck (as part of a collaboration with Taiho and Astex), which is currently in a Ph. I trial (NCT05067283) for the treatment of solid tumors either as a monotherapy or in combination with their checkpoint inhibitor immunotherapy pembrolizumab (Keytruda™). The medicinal chemistry story was recently presented at the ACS Spring 2024 meeting in New Orleans, following a presentation of the Ph. I interim results by Merck at ESMO in Oct. 2023.

Vertex’s VX-548 is a potential first-in-class, exquisitely selective, oral NaV1.8 inhibitor that recently captured headlines for its positive Ph. III data. With the ongoing opioid epidemic throughout the US, there is an urgent unmet medical need for non-addictive pain medications as alternatives to opioids. They plan to file an NDA by mid-2024 for the treatment of moderate-to-severe acute pain. This case study highlights what’s publicly known about Vertex’s journey in pain leading up to the Ph. III readout for VX-548, and why this is such a watershed moment for pain management.
