Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Background:

Recent advances in biotherapy and personalized medicine highlight the need for effective drug manufacturing methods.
Current studies on personalized drug fabrication are limited, posing a challenge for clinical translation.

Purpose of the Study:

To develop a simple, fast, and uniform method for fabricating personalized solid drugs.
To investigate the influence of geometry and UV-light exposure on drug concentration within the fabricated hydrogel.
To assess the biocompatibility and therapeutic efficacy of the developed drug delivery system.

Main Methods:

Fabrication of solid drug formulations using poly(ethylene glycol)diacrylate (PEGDA) hydrogel and doxorubicin.
Controlled variation of final drug geometry using UV-light patterning.
Analysis of PEGDA biocompatibility with surrounding cells.
Evaluation of doxorubicin release and therapeutic effect.

Main Results:

Drug concentration was significantly affected by geometrical volume and UV-light exposure time.
PEGDA hydrogel demonstrated high biocompatibility with no adverse effects on cells.
Doxorubicin-loaded PEGDA hydrogels exhibited excellent therapeutic effects, confirming successful drug release.
The fabrication method allowed for precise control over drug geometry.

Conclusions:

The developed UV-light patterning approach offers a viable method for simple, fast, and uniform fabrication of personalized solid drugs.
The PEGDA hydrogel serves as a biocompatible platform for controlled drug delivery.
This technology has the potential to advance personalized medicine through tailored drug formulations.
