CollPlant Advances its 3D Bioprinted Regenerative Breast Implants into Porcine Study

• rhCollagen-based regenerative breast implants address $2.8 billion global breast implant market with revolutionary and potentially safer new product
• Regenerative breast implants for aesthetic and reconstructive procedures including postmastectomy for cancer patients
• The study is planned to be concluded within six months

REHOVOT, Israel, June 28, 2022 /PRNewswire/ -- CollPlant (Nasdaq: CLGN), a regenerative and aesthetics medicine company developing innovative technologies and products for tissue regeneration and organ manufacturing, today announced the initiation of a study in large animals for its 3D bioprinted regenerative breast implant program, addressing the $2.8 billion global breast implant market.

"This study is a quantum leap in the development of 3D bioprinted regenerative breast implants," said Yehiel Tal, CollPlant's Chief Executive Officer.  "We believe that our regenerative breast implants will address safety challenges associated with silicone implants while also providing a more natural looking and feeling aesthetic result. Immediately following the conclusion of this study, we are planning to launch a second study with human size implants that mimic commercial products. These studies will advance us to the significant stage of human clinical trials."

CollPlant's bioprinted regenerative implants aim to overcome the challenges of existing breast procedures that use silicone implants or autologous fat transfer. According to the  U.S. Food and Drug Administration, approximately 350,000 people have reported adverse events involving breast implants between 2009 and 2019. Reports range from autoimmune symptoms to breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). CollPlant's regenerative breast implants are comprised of the Company's proprietary plant-derived rhCollagen, an ideal building block for regenerative medicine implants attributed to better bio-functionality, superior homogeneity, and improved safety. The printed implant is intended to degrade over time while promoting natural tissue regeneration and integration with host tissue. 3D bioprinting technology enables scalable production of highly precise and repeatable constructs, which can be customized to the individual anatomy of patients. The implants are designed to withstand physiological loads and to provide what CollPlant believes is a safer, more natural, and long-lasting alternative to current breast reconstruction and augmentation procedures.

To date, CollPlant has successfully produced prototypes of 3D bioprinted implants designed to regenerate breast tissue and evaluated these in a series of preclinical studies. The Company is now approaching an important milestone with the launch of a large animal study that involves the implantation of reduced-size 3D bioprinted implants in a clinically relevant porcine animal model. The study, which is planned to be concluded within six months, will evaluate adipose tissue regeneration, tissue integration, vascularization of the implant, implant degradation rate, and host tissue response to the implant. The study will also include screening of compositions and optimization of the surgical procedure, which will serve as the basis for the design of a pivotal large study with human size implants.

In the product development process, CollPlant uses computational modeling tools that enable an optimal design of the implant in terms of geometry, materials, physical properties, and biological environment. The modeling takes into consideration the internal anatomy of the breast tissue and the behavior of an implant, post-implantation.  The implant testing is rigorous and includes static and dynamic loading in order to mimic breast tissue behavior under different conditions and comply with the most stringent safety requirements.

About CollPlant

CollPlant is a regenerative and aesthetic medicine company focused on 3D bioprinting of tissues and organs, and medical aesthetics. The Company's products are based on its rhCollagen (recombinant human collagen) produced with CollPlant's proprietary plant based genetic engineering technology. These products address indications for the diverse fields of tissue repair, aesthetics, and organ manufacturing, and are ushering in a new era in regenerative and aesthetic medicine.

At the beginning of 2021, CollPlant entered into a development and global commercialization agreement for dermal and soft tissue fillers with Allergan, an AbbVie company, the global leader in the dermal filler market. Later in 2021, CollPlant entered a strategic co-development agreement with 3D Systems for a 3D bioprinted regenerative soft tissue matrix for use in breast reconstruction procedures in combination with an implant.
