Ulcerative colitis (UC) and Crohn's disease (CD), referred to collectively as inflammatory bowel disease (IBD), are chronic immune-mediated inflammatory conditions. Guidelines for treatment of UC and CD have been updated in recent years

Elafibranor (Iqirvo – Ipsen), a peroxisome proliferator-activated receptor (PPAR) agonist, has been granted accelerated approval by the FDA for treatment of primary biliary cholangitis (PBC) in adults. It is indicated for use in combination with ursodeoxycholic acid (ursodiol, UDCA; Urso, and others) in patients with an inadequate response to UDCA alone and as monotherapy in those unable to tolerate UDCA.

The FDA has approved the subcutaneously injected interleukin (IL)-4 receptor alpha antagonist dupilumab (Dupixent – Sanofi/Regeneron) for treatment of eosinophilic esophagitis (EoE) in patients ≥12 years old who weigh ≥40 kg and treatment of prurigo nodularis in adults. Dupilumab is the first drug to be approved in the US for each of these indications. It is also FDA-approved for treatment of atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis.

Nemolizumab (Nemluvio – Galderma), a subcutaneously injected interleukin-31 (IL-31) receptor antagonist, has been approved by the FDA for use in combination with topical corticosteroids and/or calcineurin inhibitors for treatment of moderate to severe atopic dermatitis in patients ≥12 years old whose disease is not adequately controlled with topical prescription drugs. It is the first IL-31 receptor antagonist to be approved in the US for this indication. Nemolizumab was approved earlier for treatment of prurigo nodularis in adults.

The FDA has approved ritlecitinib (Litfulo – Pfizer), an oral JAK and TEC kinase family inhibitor, for treatment of severe alopecia areata in patients ≥12 years old. Ritlecitinib is the second oral drug to be approved in the US for treatment of severe alopecia areata; baricitinib (Olumiant), a JAK inhibitor, is approved only for use in adults.

The FDA has approved Seglentis (Esteve/Kowa), an oral combination of tramadol hydrochloride, a weak opioid agonist and weak serotonin and norepinephrine reuptake inhibitor (SNRI), and celecoxib, a COX-2 selective nonsteroidal anti-inflammatory drug (NSAID), for use in adults with acute pain that is severe enough to require an opioid and for which alternative treatment options are inadequate.

The FDA has approved Combogesic IV (Hikma), an IV solution containing acetaminophen and ibuprofen, to treat mild to moderate pain (alone) or moderate to severe pain (in combination with an opioid) in adults when IV analgesia is considered clinically necessary. Single-drug IV solutions containing ibuprofen (Caldolor) and acetaminophen have been available in the US for years.

Seladelpar (Livdelzi – Gilead), a peroxisome proliferator-activated receptor (PPAR)-delta agonist, has received accelerated approval from the FDA for use in combination with ursodeoxycholic acid (ursodiol, UDCA; Urso Forte, and generics) for treatment of primary biliary cholangitis (PBC) in adults who had an inadequate response to UDCA and as monotherapy in those unable to tolerate UDCA. Accelerated approval was based on a reduction in alkaline phosphatase (ALP) levels. Seladelpar is the second PPAR agonist to be approved in the US for this indication; elafibranor (Iqirvo)...
