Optimizing Liposomal Amphotericin-B BE Studies

Challenges and Expert Monitoring in Liposomal Amphotericin-B BE Studies


Liposomal Amphotericin-B is a critical antifungal medication that requires careful attention during Bioequivalence (BE) studies. These studies aim to demonstrate the similarity of a generic liposomal Amphotericin B formulation to the reference drug in terms of pharmacokinetics.

Zenovel, with its extensive experience in monitoring Amphotericin B studies, can play a crucial role in overcoming the challenges associated with these complex studies.

Challenges in Liposomal Amphotericin-B Bioequivalence Studies

Concomitant Medication: 

Frequent adverse events (AEs) such as skin irritation and back pain are commonly reported by subjects receiving liposomal amphotericin-B. To mitigate the risk of allergic reactions and reduce the likelihood of AEs leading to subject dropouts, concomitant medications like Paracetamol, Hydrocortisone, and dihydrophenylamin are administered to subjects before the drug’s administration.

Intravenous Administration and Infusion Pump Calibration:

During intravenous drug administration using an infusion pump, it is important to adjust the flow rate as needed to complete dosing within the required timeframe. Despite the pump being calibrated, vigilant monitoring is still necessary to ensure the drug is delivered on time.

Frequent PK Sampling:

The challenge is further intensified by the requirement for frequent PK sampling at the end stage of IMP administration.

Bioanalytical Phase:

During the bioanalytical phase, estimating the concentration of the drug and its metabolites, presents a significant challenge. Liposomes have weak bonds and are inherently unstable, requiring a robust method for accurate recovery from the plasma. Glycerol, a cryoprotectant, is added at the time of sample collection to stabilize the molecules. The analyst should pour the aliquot slowly onto the pipette’s wall rather than directly into the poly propylene tube. However, despite this precaution, there still may be high variability between analyst-to-analyst during sample analysis, potentially impacting the study’s final results. On a positive note, Zenovel’s monitors possess extensive experience in developing and validating methods for estimating bound and unbound amphotericin, ensuring reliable and consistent outcomes.
