The following information helps you to find FDA Alerts and Pharmacist’s Applications to Practice quickly and easily. In cooperation with the Food and Drug Administration (FDA), and as a service to our members, HOPA periodically distributes information about newly approved therapies for cancer patients from FDA’s Office of Oncology Drug Products Director, Dr. Richard Pazdur to inform oncologists and professionals in oncology-related fields in a timely manner. Links to product labels will take you to relevant clinical information on the indication, contraindications, dosing, and safety. In sending this information, HOPA does not endorse any product or therapy and does not take any position on the safety or efficacy of the product or therapy described.

Along with HOPA’s Publications Committee, members also review new drug updates and provide analysis and research on the application of these new drugs or indications. Pharmacist’s Applications to Practice, or PAP, are listed after drugs that include the additional analysis. If you are interested in helping the Publications Committee with creating a Pharmacist's Application to Practice, please contact Jeff Price at jprice@hoparx.org.

You can also find additional information on FDA Alerts and Updates by listening to FDA Drug Safety Podcasts.

On July 31, 2018, the Food and Drug Administration approved lusutrombopag (Mulpleta, Shionogi Inc.) for thrombocytopenia in adults with chronic liver disease who are scheduled to undergo a medical or dental procedure.

Approval was based on two randomized, double-blind, placebo-controlled trials (L-PLUS 1 and L-PLUS 2, NCT02389621) involving 312 patients with chronic liver disease and severe thrombocytopenia who were undergoing an invasive procedure and had a platelet count less than 50 x 109/L. Patients were randomized 1:1 to receive 3 mg of lusutrombopag or placebo once daily for up to 7 days.

In L-PLUS 1, 78% of patients (38/49) receiving lusutrombopag required no platelet transfusion prior to the primary invasive procedure, compared with 13% (6/48) who received placebo (95% CI for treatment difference: 49%, 79%; p<0.0001). In L-PLUS 2, 65% (70/108) of patients who received lusutrombopag required no platelet transfusion prior to the primary invasive procedure or rescue therapy for bleeding from randomization through 7 days after the procedure, compared with 29% (31/107) receiving placebo (95% CI for treatment difference: 25%, 49%; p<0.0001).

The most common adverse reaction in ≥ 3% of patients was headache.

The recommended lusutrombopag dosage is 3 mg orally once daily with or without food for 7 days.
