Astellas and 4D Molecular Therapeutics (4DMT) Enter into License Agreement to Use 4DMT's Proprietary Intravitreal R100 Vector for Rare Ophthalmic Targets

TOKYO and EMERYVILLE, Calif., July 10, 2023 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503) (President and CEO: Naoki Okamura, "Astellas") and 4D Molecular Therapeutics, Inc. (NASDAQ: FDMT) (CEO: David Kirn, MD, "4DMT") today announced a license agreement under which Astellas gains rights to utilize the intravitreal retinotropic R100* vector invented by 4DMT for one genetic target implicated in rare monogenic ophthalmic disease(s), with options to add up to two additional targets implicated in rare monogenic ophthalmic diseases after paying additional option exercise fees.

R100 is an adeno-associated virus (AAV) vector invented by 4DMT for intravitreal delivery. It has the ability to penetrate the internal limiting membrane barrier and to efficiently transduce the entire retina, resulting in robust transgene expression within retinal cells. All three 4DMT clinical-stage ophthalmic product candidates utilize the R100 vector, including 4D-150 for wet age-related macular degeneration and diabetic macular edema.

Under the terms of the agreement, 4DMT will provide its proprietary R100 vector technology to Astellas to deliver Astellas' unique genetic payloads for the treatment of rare monogenic diseases. Astellas will conduct all subsequent research, development, manufacturing, and commercialization activities. 4DMT will receive US$20 million upfront, and potential future option fees and milestones of up to US$942.5 million including potential near-term development milestones of US$15 million for the initial target. In addition, 4DMT is entitled to receive mid-single digit to double-digit, sub-teen royalties on net sales of all licensed products.

"This collaboration with Astellas, a leader in AAV gene therapy, continues to validate R100 for routine intravitreal low dose delivery of genetic payloads for the treatment of retinal diseases," said David Kirn, M.D., Co-Founder and Chief Executive Officer of 4DMT. "With over 70 patients dosed to-date with R100-based product candidates in wet age-related macular degeneration and rare ophthalmic diseases, this collaboration also demonstrates the modularity of the Therapeutic Vector Evolution platform resulting in efficient design and development of new intravitreal products. 4DMT retains rights to large market non-hereditary ophthalmic diseases."

Adam Pearson, Chief Strategy Officer (CStO) at Astellas said, "At Astellas, we have a strong commitment to developing novel treatments for ophthalmic diseases, and have positioned Blindness & Regeneration as one of the Primary Focuses of our R&D strategy. Staying at the forefront of gene therapy technology is a key part of our strategy. We believe that this collaboration will bring synergies between the two companies' cutting-edge research, and will ultimately lead to the development of new therapeutics for patients with ophthalmic diseases at high risk of blindness."

R100 Structure & Target Vector Profile ~Intravitreal Delivery for Retinal Diseases~ A) Naturally occurring vectors cannot effectively reach the retina from the vitreous due to the inner limiting membrane (ILM) B) Therefore in many cases, genetic medicines utilizing naturally occuring vectors require subretinal injection via vitrectomy surgery C) R100 was customized and evolved to overcome the ILM barrier and transduce the retina with a routine intravitreal injection

About 4DMT
4DMT is a clinical-stage biotherapeutics company harnessing the power of directed evolution for genetic medicines targeting large market diseases. 4DMT seeks to unlock the full potential of genetic medicines using its proprietary invention platform, Therapeutic Vector Evolution, which combines the power of the Nobel Prize-winning technology, directed evolution, with approximately one billion synthetic AAV capsid-derived sequences to invent customized and evolved vectors for use in our product candidates. All of our vectors are proprietary to 4DMT and were invented at 4DMT, including the vectors utilized in our clinical-stage and preclinical pipeline product candidates: R100, A101, and C102. The Company is initially focused on five clinical-stage product candidates in three therapeutic areas for both rare and large market diseases: ophthalmology, pulmonology, and cardiology. The 4DMT customized and evolved vectors were invented with the goal of being delivered at relatively low doses through clinically routine, well-tolerated, and minimally invasive routes of administration, transducing diseased cells in target tissues efficiently, having reduced immunogenicity and, where relevant, having resistance to pre-existing antibodies. 4DMT is currently advancing five product candidates in clinical development: 4D-150 for wet AMD and DME, 4D-710 for cystic fibrosis lung disease, 4D-310 for Fabry disease cardiomyopathy, 4D-125 for XLRP, and 4D-110 for choroideremia. The 4D preclinical product candidates in development are: 4D-175 for geographic atrophy and 4D-725 for AATLD.

4D-150, 4D-710, 4D-310, 4D-125, and 4D-110 are our product candidates in clinical development and have not yet been approved for marketing by the US FDA or any other regulatory authority. No representation is made as to the safety or effectiveness of 4D-150, 4D-710, 4D-310, 4D-125, or 4D-110 for the therapeutic uses for which they are being studied.
