Drugs in Cyclodextrin in Liposomes: How a Suitable Formulation of an Active Substance Can Improve Its Efficiency?

Great paper from Prof Geraldine Gouhier, François Estour and colleagues from Université de Rouen on the design of new drug delivery systems.

Liposome formulations are pivotal in medicine for their ability to improve drug solubility, allowing for targeted delivery directly to disease sites, which minimizes side effects. They enable controlled and sustained release of medications, reducing dosage frequency. Their ability to encapsulate a variety of substances makes them versatile for different treatments, significantly reducing toxicity and enhancing the stability of drugs, especially sensitive biological compounds. This ensures a more effective and safer therapeutic approach.

Discover how the innovative “drug-in-cyclodextrin-in-liposomes” method is revolutionizing drug delivery! Enhancing drug stability & release, this latest review dives into how these nano-carriers improve the efficacy of various drugs. 🧬💊

Novel FDA Drug Approvals 2Q 2023

drug development, drug discovery,

26 new drugs approved by the FDA’s Center for Drug Evaluation and Research (CDER) for 1H! Lots of exciting new mechanisms and modalities.

Highlights from the 2Q include –

💉 Tofersen (Qalsody), an antisense oligonucleotide indicated for the treatment of adult amyotrophic lateral sclerosis caused by SOD1 mutation.

💉 Pegunigalsidase alfa (Elfabrio), a recombinant form of human α-galactosidase-A indicated for long-term enzyme replacement therapy in patients with Fabry disease.

💊 Fezolinetant (Veozah), a selective neurokinin-3 (NK3) receptor antagonist used to treat moderate to severe vasomotor symptoms due to menopause.

👁 Perfluorohexyloctane (Miebo) is a drug used to treat dry eye disease. Check out structure! Mechanism unknown.

💉Epcoritamab (Epkinly), a bispecific CD20-directed CD3 T-cell engager used to treat relapsed or refractory diffuse large B-cell lymphoma (DLBCL) in adults.

💊 Sulbactam/durlobactam (Xacduro), a co-packaged medication used for the treatment of bacterial pneumonia caused by Acinetobacter baumannii-calcoaceticus complex. It contains sulbactam, a beta-lactam antibacterial and beta-lactamase inhibitor; and durlobactam, a beta-lactamase inhibitor.

💊 Nirmatrelvir/ritonavir (Paxlovid), a co-packaged medication used as a treatment for COVID‑19. It contains the antiviral medications nirmatrelvir and ritonavir. Nirmatrelvir is a SARS-CoV-2 main protease inhibitor while ritonavir is a HIV-1 protease inhibitor and strong CYP3A4 inhibitor.

💉Flotufolastat F-18 (Posluma), a radiopharmaceutical diagnostic agent used in PET imaging to visualize PSMA-positive lesions in men with prostate cancer with suspected metastasis or recurrence.

💊 Sotagliflozin (Inpefa), a dual SGLT1/2 inhibitor used to reduce the risk of CV, hospitalization for heart failure, and urgent heart failure visit in adults with heart failure or type 2 diabetes mellitus, chronic kidney disease, and other cardiovascular risk factors

💉Glofitamab (Columvi), a bispecific mAb directed against CD20 and CD3 which is used for the treatment of relapsed or refractory diffuse large B-cell lymphoma.

💊 Ritlecitinib (Litfulo), a dual JAK3/TEC kinase family inhibitor used to treat severe alopecia areata in adults and adolescents 12 years and older.

💉Rozanolixizumab (Rystiggo), a humanized mAb targeting the human neonatal Fc receptor (FcRn) used to treat generalized myasthenia gravis.

💉Somatrogon (Ngenla), a long-acting recombinant human growth hormone used as the long-term treatment of pediatric patients who have growth failure due to growth hormone deficiency.

Again, a fascinating collection from Chris de Savi!

Targeted protein degradation (TPD)

drug development, , ,

Clinical Degrader Drugs 
Targeted protein degradation (TPD) is an emerging field in drug discovery that aims to selectively remove disease-causing proteins from cells. By directly targeting and eliminating proteins, TPD has the potential to address a wider range of disease targets, including those that have been traditionally considered “undruggable.”
Many highly selective PROTAC molecules with improved drug-like properties are entering clinical trials.
Some of the most exciting compounds being profiled are highlighted below

💊Vepdegrestrant (ARV-471), an orally bioavailable estrogen receptor (ER) protein degrader for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer.

💊Bavdegalutamide (ARV-110), an orally bioavailable androgen receptor (AR) protein degrader for the treatment of metastatic castration-resistant prostate cancer (mCRPC).

💊ARV-766, an orally bioavailable AR degrader for the treatment of mCRPC.

💊NX-2127, an orally bioavailable Bruton’s tyrosine kinase (BTK), Ikaros (IKZF1) and Aiolos (IKZF3) degrader for the treatment of R/R B cell malignancies.

💊NX-5948, an orally bioavailable BTK degrader for the treatment of R/R B cell malignancies.

💉DT-2216, an IV administered selective B-cell lymphoma-extra large (Bcl-XL) protein degrader for the treatment of T-cell lymphomas.

💉FHD-609, an IV administered BRD9 protein degrader for the treatment of synovial sarcoma.

💊CFT1946, an orally bioavailable mutant BRAF kinase protein degrader for the treatment of various BRAF V600E-driven cancers.

💊CFT8634, an orally bioavailable BRD9 protein degrader for the treatment of synovial sarcoma.

💊KT-474, an orally bioavailable IRAK4 protein degrader for the treatment hidradenitis suppurativa (HS) and atopic dermatitis (AD).

💉KT-413, an IV administered IRAK4, IKZF1 and IKZF3 protein degrader for the treatment of  MYD88-mutant B cell lymphomas.

💉KT-333, an IV administered STAT3 protein degrader for the treatment of Peripheral T-cell Lymphoma (PTCL).
