Samir Mitragotri, PhD, a bioengineering professor at Harvard University and founder of CAGE Bio, is pioneering new approaches in dermatological medicine. His groundbreaking research focuses on utilizing ionic liquid-based therapeutics to improve drug delivery directly to the skin, offering the potential to enhance treatment outcomes while minimizing systemic side effects.
Revolutionizing Drug Delivery with Ionic Liquids
Ionic liquids, a type of liquid salts made from organic ions, have gained attention for their ability to dissolve drugs more effectively and increase skin permeability. Mitragotri’s work explores how these properties can enable more efficient drug integration into dermatological treatments, particularly for complex agents like peptides and nucleic acids. By targeting localized delivery, his approach aims to reduce off-target effects, offering a safer and more effective treatment for various skin conditions.
“Our goal is to create a platform that significantly enhances molecule transport into the skin, while being simple, scalable, and easily incorporated into topical products,” said Mitragotri.
Tackling Immunodermatological Disorders
Mitragotri’s research also delves into immunodermatology, focusing on skin diseases related to immune system dysfunction. Conditions like atopic dermatitis and alopecia areata, which are characterized by immune dysregulation, present significant treatment challenges. Traditional systemic therapies often come with safety and effectiveness trade-offs. Mitragotri proposes localized, topical treatments as a safer and more targeted alternative for patients.
“As new molecules with innovative mechanisms of action continue to emerge, dermatology can only benefit from them if they can be delivered topically. That’s where technology like ionic liquids bridges the gap,” Mitragotri explained.
Promising Clinical Trials and New Developments
CAGE Bio has successfully applied ionic liquid technology to develop products like CGB-500, a topical treatment for atopic dermatitis. A phase 2a clinical trial in 2023 demonstrated significant results, with a 98% improvement in disease severity among participants compared to a 28% improvement in the placebo group.
“We focus on how well products perform compared to a placebo, and these results are promising,” Mitragotri noted.
The company is also advancing treatments for alopecia areata and vitiligo, including a DNA aptamer-based therapy, aiming to address both common and rare skin conditions.
