Petra Pharma Corp. has patented phosphatidylinositol 3-kinase α (PI3Kα, PIK3CA) (H1047R mutant) allosteric inhibitors reported to be useful for the treatment of cancer, congenital lipomatous overgrowth, vascular malformations, epidermal naevi and skeletal abnormalities and PIK3CA-related overgrowth spectrum.
High levels of adenosine known to stimulate tumor immunoevasion are formed by the ecto-5’-nucleotidase enzyme (CD73) conversion of adenosine monophosphate to adenosine. CD73 is a cell surface enzyme that is overexpressed in many cancer types where this overexpression has been correlated with a poor prognosis.
Neuroblastoma is among the deadliest cancers in infants, with frequent relapse and long-term survival being <10%. Recently, it has been found that protein RD3 is constitutively expressed in healthy adult and fetal tissues beyond the retina, and it follows a gradient expression from high to low levels in ganglioneuroma and neuroblastoma.
Triple-negative breast cancer (TNBC) constitutes the most aggressive form of breast cancer and presents a high frequency of relapse. The available treatment options are limited and accompanied by resistance and significant treatment side effects.
Bridge Biotherapeutics Inc. has received FDA clearance to proceed with a first-in-human study of BBT-207, a potential broad-spectrum fourth-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) for the treatment of non-small-cell lung cancer (NSCLC).
Researchers from Jacobio Pharmaceuticals Co. Ltd. have reported preclinical data for JAB-X1800, an immunostimulatory antibody-drug conjugate (iADC) targeting CD73. JAB-X1800 was developed using an anti-CD73 monoclonal antibody (MAb) for targeted delivery of a highly potent noncyclic dinucleotide STING agonist payload, JAB-27670.
The infiltration of regulatory T cells (Tregs) into the tumor microenvironment and a low ratio of effector T cells to Tregs is usually tied to tumor progression and poor prognosis. On the other hand, interleukin-2 receptor subunit α (IL-2-RA) is highly expressed on Tregs.
Researchers from Flare Therapeutics Inc. presented the discovery of a first-in-class covalent peroxisome proliferator-activated receptor γ (PPARγ) inverse agonist, FX-909, being developed for the treatment of urothelial cancer (UC). Synthesis and optimization of covalent lead series of agonists of the PPARγ lineage transcription factor led to the discovery of FX-909 as the lead covalent PPARγ inverse agonist with powerful repressive conformational biasing activity.
Daiichi Sankyo Co Ltd. has experienced yet another setback with its quizartinib NDA submission, as the U.S. FDA has now extended the review period by three months to July 24, 2023, to allow additional time to review requested updates to the proposed Risk Evaluation and Mitigation Strategies. No additional efficacy or safety data has been requested.
New and updated clinical data presented by biopharma firms at the American Association for Cancer Research annual meeting, including: Innovent, Primmune.
