The undrugged transcription factor interferon regulatory factor 5 (IRF5) is involved in autoimmune disorders such as Sjogren’s disease and rheumatoid arthritis in which dysregulation of IRF5 leads to autoantibody formation and secretion of pro-inflammatory cytokines, with type I interferon exacerbating inflammation. Totus Medicines Inc. has presented preclinical data regarding a novel IRF5 inhibitor for controlling autoimmune disorders.

If Benjamin Braddock, of The Graduate fame, were a young neuroscientist in the 21st century instead of a liberal arts graduate in 1967, the advice he received from his parents’ neighbor might not have been “One word: plastics!” but “One word: plasticity!” Plasticity is a hot concept in neuropsychiatric disorders. New and old treatment modalities, these days, are said to work as psychoplastogens or neuroplastogens.

Artificial intelligence tools are springing up at multiple points along drug discovery and development, but despite the hype, as yet there is minimal return on investment (ROI). “I would say a lot of companies sort of get this big excitement about AI, but then when you look at how much ROI they get, it’s actually very little. And that’s because the workflow and the process, end-to-end, isn’t mapped to really understand where AI can truly make an impact,” said Laura Matz, chief science and technology officer at Merck KGaA.

Homozygous deletion of methylthioadenosine phosphorylase (MTAP), present in ~15% of tumors, leads to accumulation of methylthioadenosine and partial inhibition of protein arginine methyltransferase 5 (PRMT5), creating a synthetic-lethal vulnerability that sensitizes tumors to PRMT5-targeted therapies. Researchers from Beone Medicines Ltd. presented preclinical efficacy data of BGB-58067, an MTA-cooperative PRMT5 inhibitor, in models of tumors with MTAP-deficiency.

An advantage of antibody-drug conjugates (ADCs) is that they allow targeted delivery of cytotoxic agents into tumors, thus improving the therapeutic index. Pfizer Inc. has developed a new ADC, PF-08046033, that contains auristatin S (AurS) as the cytotoxic payload and targets transmembrane glycoprotein NMB (GPNMB).

Chengdu Kanghong Pharmaceutical Group Co. Ltd. is developing a nonopioid Nav1.8 inhibitor, KHN-702. The effects of KHN-702 were evaluated both in vitro and in vivo, in a plantar incision pain model, and results were presented at the recent American Academy of Neurology meeting in Chicago.

Neomorph Inc.’s NEO-811 is a molecular glue degrader designed to induce targeted degradation of ARNT and suppress this signaling pathway implicated in clear cell renal cell carcinoma (ccRCC). Targeting ARNT offers a complementary strategy to broadly disrupt oncogenic HIF signaling in ccRCC.

Minimal residual disease (MRD) has become a central concept in modern oncology, reshaping how clinicians evaluate response, relapse risk and treatment precision. As increasingly sensitive technologies reveal traces of cancer that persist after therapy, MRD is emerging as both a biological challenge and a clinical opportunity, especially as new data illuminate its complexity across hematologic and solid tumors. This topic was addressed at the 2026 American Association for Cancer Research (AACR) annual meeting.

Incyte Corp. has developed and presented data for their CD70xCD3 bispecific antibody INCA-036873, which was designed to activate T cells and kill tumoral cells expressing CD70.
