Description

CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY



[0001] The present application claims priority from Indian patent application no. 201921020188, filed on May 21, 2019. The entire contents of the aforementioned application are incorporated herein by reference.

TECHNICAL FIELD



[0002] The disclosure herein generally relates to therapeutic system, and, more particularly, to system and method for in-silico design and testing of vehicles and formulations for delivery of active molecules.

BACKGROUND



[0003] In healthcare and personal care industries, a drug delivery system (DDS) is a formulation or a device that enables introduction of a therapeutic substance into the body and improves its efficacy and safety by controlling the rate, time, and place of release of drugs in the body. Some of the common routes of administration include the enteral (gastrointestinal tract), parenteral (via injections), inhalation, transdermal, topical, and oral routes. One of the key challenges in the healthcare and personal care industries is arriving at an optimum delivery vehicle and formulation (for a given active molecule) which can deliver a specified molecule to an intended site of action with minimal or no side effects. The problem becomes more tedious as the active molecule can be delivered through various routes such as intravenous, oral, transdermal, intramuscular to name a few.

[0004] A delivery vehicle and a formulation is a key to achieve desired release of the active molecule for a given delivery route of administration and uptake mechanism. For example, controlled release can be achieved by loading drugs/chemicals in a polymer hydrogel. This technology now spans many fields such as pharmaceutical, food and agricultural applications, pesticides, cosmetics, and household products. Currently design of the delivery vehicle and formulation is carried out by trial and error detailed experiments with almost no or vey less digital intervention. To add more complexity, potential formulations are further tested on in-vitro model, animal models (in-vivo). The formulation goes for clinical trials (in Humans) after successful result in the previous stage. In current industry standards, for a drug from its inception to market, it takes eight to ten years and much higher spending and every year several animals are killed for in-vivo testing. Even after that, almost 90 percent of drug are getting failed at various stages of clinical trials.

The same skin can also be represented a simple multilayer diffusion model where molecular details are not needed/omitted. In an embodiment, the user requests the knowledge database to select the appropriate model based on the application. For example, to design a skin permeation enhancer, which changes the skin structure at nanoscale, skin's molecular model is needed.

[0036] In an embodiment, the model parameters can be either provided as an input by user or can be obtained from the knowledge database or using empirical relation. Based on the model, the parameters can be structural, transport or thermodynamics properties of organ, route, formulations or active molecule to be delivered. In an embodiment, the knowledge database includes model feasibility information which, based on the selected delivery vehicle, formulation or the combination of both along with the type of in-silico model of the delivery route decides whether it is computationally feasible to carry out in-silico simulation in stipulated amount of time. The knowledge database in updated at every instance of platform is executed.
