CollPlant’s Collink.3D®
BioInks and Technologies Offer a Relevant and Timely
Solution to FDA’s Plan to Reduce Animal Testing in Preclinical Safety Studies
CollPlant’s
novel rhCollagen BioInks are an available solution aligned with FDA’s plan
announced last week to phase out the animal testing
requirement for the development
of monoclonal antibody therapies and other drug candidates
REHOVOT, Israel, April 15, 2025 – CollPlant Biotechnologies (Nasdaq:
CLGN), or “CollPlant”, a regenerative and aesthetics medicine company developing innovative technologies and products based
on its non-animal-derived, rhCollagen for tissue regeneration and medical aesthetics, commented today, following the United States Food
and Drug Administration (FDA)’s groundbreaking step announced last week to advance public health by replacing animal testing in
the development of monoclonal antibody therapies and other drug candidates with more effective, human-relevant methods. Importantly, CollPlant’s
Collink.3D® portfolio of rhCollagen-based BioInk products can be utilized for the biofabrication of tissue-on-a-chip
or organ-on-a-chip systems, which serve as alternatives to animal testing. These systems can expedite the gap between benchtop studies
and clinical trials, as well as be more economical and enable a reduced time to market.
Yehiel Tal, CollPlant’s Chief Executive Officer, commented, “The
FDA’s new approach to develop alternatives for use in place of traditional animal testing, often referred to as “New Approach
Methodologies”, or NAMs, is designed to improve drug safety and accelerate the evaluation process, while reducing animal experimentation,
lowering research and development costs, and ultimately, drug prices. CollPlant’s novel rhCollagen-based Collink.3D portfolio of
BioInk products supports the FDA’s NAMs since they can be used in a wide variety of non-animal testing applications. For example,
CollPlant’s BioInk products are ideal for the biofabrication of tissue-on-a-chip or organ-on-a-chip systems used for drug discovery
and regenerative medicine applications and are designed to be compatible with in-vitro human-based systems like organoids. We anticipate
that our BioInks will be instrumental to enable alternatives for achieving the goal of phasing out animal testing in five years.”
Mr. Tal added, “CollPlant has also developed Computational Modeling
and Simulation (CM&S) methodologies to assist in the development of its regenerative breast implant product candidate. Mimicry of
the implant and human body interaction using CM&S, enables precise prediction of mechanical behavior of the implants in the body,
as well as provides information about degradation kinetics, tissue remodeling and interaction with the host tissue. These smart tools
are reducing the need for animal studies and are accelerating the development of safer and more effective human-specific solutions. The
same development tools can be applied to any other soft or hard tissue type to optimize the development of regenerative implants.”

About Collink.3D BioInk
CollPlant’s Collink.3D BioInk pipeline consists of the
first and only line of human collagen BioInk products based on chemically modified plant-derived rhCollagen that is mass-produced with
high purity and consistency.
CollPlant’s BioInk Collink.3D pipeline of products are
based on a methacrylated form of its rhCollagen which can be used for 3D bioprinting of tissues and organs. CollPlant’s BioInk is
currently being utilized for the printing of its regenerative breast implants in development. By combining biomaterials and synthetic
polymers, CollPlant Collink.3D can be utilized for tissue-on-a-chip or organ-on-a-chip systems, which enable real-time, human-relevant
assessment of immune responses, degradation, and tissue remodeling.
Collink.3D enables scalable and reproducible biofabrication
of tissue models, tissues, and organ transplants, while perfectly mimicking the native properties of tissues and organs. Additionally,
it provides the advantage of being animal-free, has the properties of optimal rheology at room temperature, supports high viability of
different cell types and is biocompatible and non-immunogenic.
About the U.S. FDA Announcement to Phase Out Animal Testing
On April 10, 2025, the FDA announced a plan to phase out animal testing
as a requirement for the pre-clinical development of monoclonal antibodies and other drugs.
The FDA’s statement specifies that within 3–5 years, animal
testing may become the exception. Incentives and collaborative efforts across industry and government are accelerating this shift. This
is intended to be the road to safer drugs, reduced development timelines and ethical research practices.
About CollPlant
CollPlant is a regenerative and aesthetic medicine company ushering
in a new era of medical solutions with a focus on 3D bioprinting of tissues and organs, tissue repair 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.
In 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.
