PharmaShell® benefits from ALD's versatility, enhancing drug efficacy, minimizing side effects, and allowing tailored treatment plans. ALD's role in crafting PharmaShell® exemplifies its impact in advancing drug delivery systems, revolutionizing pharmaceutical care.
The study, conducted with great precision and care, involved nine healthy volunteers who were administered either one or two subcutaneous single injections of the innovative NEX-20A formulation. This formulation encompassed doses ranging from 15 to 35 mg of lenalidomide, with a maximum cumulative dosage of 50 mg. The outcome was nothing short of remarkable, as the observed pharmacokinetic data from the human participants correlated excellently with the projected exposure calculated from preclinical studies.
Central to the accomplishment was the remarkable release mechanism employed by Nanexa, known as PharmaShell®. This ingenious approach ensured a controlled and gradual release of the drug into the participants' bodies, creating a plasma curve that spanned an impressive 21 days. A critical observation from the study was the initial low release of the total dosage within the first day. This gradual release strategy plays a pivotal role in maintaining optimal levels of the drug in the bloodstream throughout the treatment period.
Equally encouraging was the confirmation that the total exposure of lenalidomide in the plasma—measured as the area under the curve (AUC)—escalated proportionally with the administered dose. This finding aligns with the expectations and demonstrates the efficacy of the PharmaShell® system in achieving the desired therapeutic outcomes.
Nanexa's CEO, David Westberg, expressed his enthusiasm regarding this groundbreaking achievement. "This is an important achievement for Nanexa, to once again demonstrate that we can predict the release profile of PharmaShell® in humans based on preclinical data," he shared.
