Disintegrating Pre-formed Oral Dosages to Improve Solubility


Disintegrating Pre-formed Oral Dosages: DPODs

DPODs create an optimal combination of high drug stability, fast dissolution rate, and prolonged levels of high supersaturation in an oral dosage form capable of higher drug loading than current formulations. 

Solid State Stability

We control the chemistry of our DPODs to spontaneously transform an API into nanocrystals within the three-dimensional covalently cross-linked polymer network.

High Solubility

Hydrogels decompose into solubility enhancing polymers while releasing nanocrystalline API, which improve the dissolution rate and solubility above levels that either can achieve independently. 

High Drug Loading

Hydrogels are initially composed by as little as 10% (by volume) polymer and can be made to swell to further increase the remaining volume of nanopores to load with API.

Chemical Versatility

A Platform Technology

Current formulation techniques (e.g., nanocrystals, amorphous dispersions, and lipid formulations) to improve drug solubility are effective for compounds with specific combinations of physical properties (e.g., melt temperature and lipophilicity or LogP). In many cases, a given API falls outside the compatibility region of current formulations, which hinders the development of potentially therapeutic compounds. 


In contrast, DPODs can serve as an effective delivery vehicle for essentially any compound due to their chemical versatility. As a result, DPODs can dramatically simplify the formulation development process and expand the number of drugs as lead compounds. Their robust mechanical properties make DPODs uniquely capable of transforming lipid formulations and liquid APIs into oral solid dosages. Further, the solution processing utilized for drug loading is a preferred approach for handling highly potent drugs (HPAPIs) as opposed to powder processing.

Efficiency of a Pre-formed Oral Dosage

DPODs simplify drug product design and manufacturing to accelerate clinical translation and improve performance.

Due to the sensitive dependence of critical processing parameters (CPPs) on critical material attributes (CMAs) and their combined influence on the desired critical quality attributes (CQAs), each process that a drug product is exposed to during manufacturing (see the figure above) must be designed and qualified using an extensive quality by design (QbD) process. 

Since several processes are required to produce tablets using currently available solubility enhancing formulations, a "fit-for-purpose" dosage is used in early stage development to minimize the investment into potentially failed APIs then converted into a commercially viable tablet during clinical trials.

DPODs avoid the need for excipient compatibility studies and therefore drastically accelerate early stage formulation design. The minimal impact of process parameters of drug product performance avoids significant manufacturing modifications and can significantly accelerate scale-up and process validation required for clinical translation. 


Drug Delivery

In addition to their versatility and simplicity, DPODs are capable of improving the solubility and controlling the release profile through their polymer chemistry before and after decomposing upon ingestion. The result is a stable dosage form that achieves immediate release up to high levels of supersaturation in physiologically relevant media. These release profiles are consistent despite varying from 30% to 60% by weight of drug substance.
