Novel Macromolecular IV to Oral Delivery Conversion Pathway: Anti-thrombolytic post-surgical – Catalent OptiGel Bio™ Technology

Reporter: Aviva Lev-Ari, PhD, RN

Case Study

OptiGel BioTechnology Enables IV to Oral Therapy Conversion

Executive Summary

An early-stage biotechnology company had developed a novel macromolecular intravenous (IV) therapy for an anti-thrombolytic post-surgical indication. While the therapy had shown complete absorption via IV, the dose form was not ideal due to a number of factors including manufacturing costs, compliance, and ease of use, as well as as well as the long term treatment requirements. This case study demonstrates how Catalent OptiGel Bio™ technology can provide a pathway for an IV to oral delivery conversion, resulting in enhanced therapies for patients.

The Challenges

Though soluble, the macromolecule presented a number of permeability challenges, which hindered delivery of an active therapeutic dose across the lumen of the small intestine to achieve the desired therapeutic effect.

By incorporating OptiGel Bio™ technology and our formulation expertise, an optimized oral therapy was developed combining permeation enhancement and targeted delivery.

physiochemical properties High molecular weight (>2500 Da)Strong negative charge*

Rigid, inflexible geometry*

targeted delivery Functional API must be delivered to the small intestine in order to achieve bioavailability
permeability Mucus layer physical barrierRandom and limited transcellular pathways

“Fence and gate” function of tight junctions

pharmacokinetic profile Oral delivery must reach exposure within therapeutic range

The Catalent Solution

Conclusion

Using OptiGel Bio™ technology, we overcame the challenges traditionally associated with the oral delivery of macromolecules and enabled conversion from an IV to a more efficient, more convenient and less invasive oral dose form while maintaining an effective pK profile. Through a multi-step drug delivery screening process and our OptiGel Bio™ technology, we can enable enhanced therapies—resulting in better treatments and more value for innovators, healthcare professionals and patients.
