Leqselvi for Alopecia Areata: The FDA has approved deuruxolitinib (Leqselvi) as a first-line treatment for adults with moderate to severe alopecia areata (AA). Developed by Sun Pharma, this oral selective inhibitor of Janus kinases JAK1 and JAK2 is typically dosed at 8 mg twice daily. The approval, based on the THRIVE-AA1 and THRIVE-AA2 trials, marks an important addition to limited treatment options for AA, which has significant psychological impacts.
Femlyv Dissolvable Birth Control: The FDA has approved norethindrone acetate and ethinyl estradiol (Femlyv) as an oral dissolvable birth control pill, expanding access for those who have difficulty swallowing. This form of hormonal birth control, in use since 1968 as a swallowable tablet, also helps manage conditions like endometriosis and PMDD. The approval, based on a study of 743 women, offers a new option with common side effects like headache and nausea.
Brineura for Batten Disease: The FDA has expanded the indication for cerliponase alfa (Brineura) to treat neuronal ceroid lipofuscinosis type 2 (CLN2 disease) in children under 3 years of age. Developed by BioMarin Pharmaceutical, this enzyme replacement therapy, initially approved in 2017, is administered by infusion into the brain. The expanded approval was based on a phase 2 trial showing reduced motor function decline and delayed disease onset.
Erzofri for Schizophrenia: The FDA has approved paliperidone palmitate (Erzofri) extended-release injectable suspension for treating schizophrenia and schizoaffective disorder in adults. This long-acting injectable (LAI) antipsychotic, administered once a month, improves patient adherence by reducing dosing frequency. Developed by Luye Pharma Group, it was granted a U.S. patent in 2023 and approved under the 505(b)(2) pathway.
Eque-cel for MS: The FDA has approved the IND application for equecabtagene autoleucel (Eque-cel) for treating multiple sclerosis (MS). Developed by IASO Biotechnology, this chimeric antigen receptor autologous T cell injection showed promising efficacy in six autoimmune diseases in a Chinese trial. MS, affecting 3.07 million people worldwide, is characterized by CNS demyelination and neuronal injury, with Eque-cel offering a new treatment option.
Spravato for TRD: Johnson & Johnson has submitted an sNDA for esketamine (Spravato) as a monotherapy for adults with treatment-resistant depression (TRD). Already approved in combination with an oral antidepressant, esketamine is an NMDA receptor antagonist that rapidly alleviates depressive symptoms. The submission is based on Phase 4 TRD4005 study results, showing rapid improvement in depression scores with a consistent safety profile.
ZW191 Anti-Tumor Agent: The FDA has cleared the IND application for ZW191, a novel antibody-drug conjugate (ADC) targeting folate receptor alpha (FR⍺) in cancers like gynecologic and NSCLC. Developed by Zymeworks, this TOPO1i ADC uses a novel payload, ZD06519, showing robust antitumor activity and a tolerable safety profile in preclinical models. Clinical development of ZW191 is planned to begin in the second half of 2024.
