**CollPlant Biotechnologies Announces Positive Results from non-clinical Studies of its Photocurable Regenerative Dermal and Soft Tissue Filler** 

 

*CollPlant is now moving towards clinical trials and scaling and optimizing its manufacturing to ensure readiness for the upcoming clinical trials*

REHOVOT, Israel September 30, 2025 - CollPlant Biotechnologies (Nasdaq: CLGN), a regenerative and aesthetic medicine company developing disruptive technologies and products based on its proprietary non-animal recombinant human collagen (rhCollagen), today announced positive results from its non-clinical program evaluating its photocurable dermal filler, as well as plans to advance this product candidate into clinical trials. This novel filler represents a significant breakthrough in aesthetic medicine by uniquely integrating contouring precision, structural support, and tissue regeneration into a single treatment.

CollPlant's formulation combines hyaluronic acid with a modified form of rhCollagen to deliver both immediate and long-lasting benefits. Administered as a viscoelastic gel through a fine needle, the filler allows physicians to sculpt precise contours, which are then stabilized using CollPlant's proprietary illumination device. Upon light activation, the gel transitions into a semi-solid, cohesive implant that withstands gravitational and mechanical forces while maintaining the desired shape.

"The successful completion of our extensive non-clinical program marks an important milestone for CollPlant allowing us to enter clinical development of our photocurable regenerative filler," said Yehiel Tal, Chief Executive Officer of CollPlant. "By harnessing the unique properties of our rhCollagen technology, we aim to redefine the standard of care in aesthetic medicine with a novel solution that not only delivers immediate contouring and support but also promotes natural tissue integration for long-lasting results. We are excited to advance this product candidate another step towards the clinic and closer to providing physicians and patients with a next-generation alternative."

CollPlant's non-clinical program included a comprehensive set of safety and performance evaluations: a one-year, *in vivo* study confirming long-term durability; biocompatibility assessments demonstrating compliance with international relevant standards. The combined results obtained establish a strong foundation for clinical advancement, and CollPlant is now scaling and optimizing its manufacturing process to ensure readiness for the upcoming clinical trial.
