Exciting news from ASHP Mid-Year. Joanne Stubbings, B.S. Pharm., MHCA, announced the creation of the Section of Specialty Pharmacy Practitioners. It’s the first new section created in twelve years.

The section’s mission is to advance the cause of health system-based specialty pharmacy practice. Three advisory groups have been created: workforce development, business development, and outcomes and values.
The FDA approved Loxo Oncology/Bayer’s larotrectinib (Vitrakvi) on 11/26/18 for the treatment of adult and pediatric locally advanced or metastatic solid tumors harboring a neurotrophic tyrosine receptor kinase (NTRK) gene fusion regardless of site. Larotrectinib is dosed as a 100 mg capsule twice a day in adults and 100 mg/Meter-Squared orally twice daily in children. WAC for a 30-day supply of the drug will be $32,800 for adult dose capsules and start at $11,000 per month for a pediatric liquid. This is the second biomarker guided therapy after the approval of pembrolizumab last May for the treatment of microsatellite instability-high cancer in any location. Bayer and Loxo provide a value-based contract for larotrectinib that will refund payers and patients for patients who do not see a clinical benefit within the first three months of treatment. The companies will also offer patient assistance and reimbursement programs to lower patient costs. Loxo estimates there are 1,500 and 5,000 late-stage cancer patients in the U.S. and a similar number in Europe with the mutation.
