The US FDA approved Besremi (ropeginterferon alfa-2b-njft) for essential thrombocythemia (ET), the first new FDA-approved ET drug in nearly 30 years, based on superior efficacy compared to anagrelide in the Phase III SURPASS-ET trial.

This Wire brief sits within Fusion42's coverage of Biotech.

◆ The Wire takeaway

You have a new FDA-approved option to contest with Anagrelin in ET treatment, giving you a chance to pitch Besremi's longer dosing intervals and potential molecular benefits in sales or partnerships.
