Martin Whitaker, Chief Executive Officer of Diurnal, commented:

“We are pleased to be able to show continued growth of Alkindi® revenues in our core commercial markets, despite the continued challenges in accessing hospitals due to Covid-19 pandemic restrictions that are impacting both patients and our commercial team. Physician feedback indicates that the majority of new-born patients in these core markets now begin treatment with Alkindi®. As pandemic restrictions begin to ease, we expect to accelerate Alkindi® revenue growth as older patients can return to clinics and be initiated on this drug.

“The recent approvals for Efmody® in adult and adolescent CAH will enable our commercial organisation to focus on both adult and paediatric endocrinologists, providing significant synergies with the continued promotion of Alkindi®. We are now preparing for the commercial launch of Efmody® in the third quarter of 2021 which will catalyse the progression of our European cortisol deficiency franchise towards profitability.

“We are also pleased with the continued geographic expansion for Alkindi® and Efmody® and look forward to working with our partners to bring these treatments to patients across the globe.”

The first indication for Efmody® is Congenital Adrenal Hyperplasia (CAH) in adults and adolescents (children older than 12 years of age).
