The FDA has approved an oral tablet formulation of sodium sulfate, magnesium sulfate, and potassium chloride (Sutab – Braintree) for colon cleansing prior to colonoscopy in adults. A sodium sulfate-based oral solution (Suprep) has been available in the US since 2010. Sutab is the second tablet formulation to be approved for bowel cleansing prior to colonoscopy; a sodium phosphate-based tablet (OsmoPrep) was approved earlier.

Esketamine (Spravato – Janssen), an intranasal N-methyl-D-aspartate (NMDA) receptor antagonist that was previously approved by the FDA for treatmentresistant depression,1 has now been approved for treatment of depressive symptoms in adults with major depressive disorder (MDD) and acute suicidal ideation or behavior. Esketamine is the S-enantiomer of the anesthetic ketamine (Ketalar, and generics). It is the first drug to be approved for this indication. Most clinical trials of antidepressants have excluded patients with acute suicidal ideation.

A synthetic form of the protein apoaequorin is the active ingredient in the over-the-counter dietary supplement Prevagen (Quincy Bioscience), which is heavily marketed to improve memory.

The oral poly(ADP-ribose) polymerase (PARP) inhibitor olaparib (Lynparza – AstraZeneca) has been approved by the FDA for adjuvant treatment of adults with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm), human epidermal growth factor receptor 2 (HER2)-negative, high-risk early breast cancer who received prior neoadjuvant or adjuvant chemotherapy. The drug was previously approved for treatment of adults with deleterious or suspected deleterious gBRCAm, HER2-negative metastatic breast cancer who received chemotherapy in the neoadjuvant, adjuvant, or metastatic...

The oral poly(ADP-ribose) polymerase (PARP) inhibitor olaparib (Lynparza – AstraZeneca) has now been approved by the FDA for use in combination with abiraterone (Zytiga, and others) and either prednisone or prednisolone for treatment of adults with deleterious or suspected deleterious BRCA-mutated (BRCAm) metastatic castration-resistant prostate cancer (mCRPC). Olaparib was previously approved by the FDA for treatment of adults with deleterious or suspected deleterious germline or somatic homologous recombinant repair (HRR) genemutated mCRPC who progressed on prior treatment with...

The oral poly(ADP-ribose) polymerase (PARP) inhibitor talazoparib (Talzenna – Pfizer) has been approved by the FDA for use in combination with the androgen receptor blocker enzalutamide (Xtandi) for treatment of adults with homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC). The drug has been available since 2018 for treatment of deleterious or suspected deleterious germline BRCA-mutated (gBRCAm), HER2-negative locally advanced or metastatic breast cancer.

Akeega (Janssen), a fixed-dose combination of the oral poly(ADP-ribose) polymerase (PARP) inhibitor niraparib (Zejula) and the antiandrogen abiraterone acetate (Zytiga, and others), has been approved by the FDA for use in combination with prednisone for treatment of adults with deleterious or suspected deleterious BRCA-mutated (BRCAm) metastatic castration-resistant prostate cancer (mCRPC). Niraparib has been available since 2017 for treatment of epithelial ovarian, fallopian tube, or primary peritoneal cancer. Abiraterone acetate has been available since 2011 for treatment of CRPC...

Fidanacogene elaparvovec-dzkt (Beqvez – Pfizer), an adeno-associated virus (AAV) vector-based gene therapy, has been approved by the FDA for treatment of adults with moderate to severe hemophilia B who do not have neutralizing antibodies to AAV serotype Rh74var and currently receive factor IX prophylaxis therapy or have had life-threatening hemorrhage or repeated, serious, spontaneous bleeding episodes. Beqvez is the second single-dose gene therapy to be approved in the US for treatment of hemophilia B; Hemgenix was the first.

Afamitresgene autoleucel (Tecelra – Adaptimmune), a melanoma-associated antigen A4 (MAGE-A4)-directed genetically modified autologous T-cell immunotherapy, has received accelerated approval from the FDA for one-time treatment of adults with unresectable or metastatic synovial sarcoma who received prior chemotherapy and are HLA-A*02:01P, -A*02:02P, -A*02:03P, or -A*02:06P positive and whose tumor expresses the MAGE-A4 antigen. It is the first gene therapy to be approved in the US for treatment of synovial sarcoma. Accelerated approval of the immunotherapy was based on the...
