MeiraGTx will receive $200 million in upfront cash at closing and MeiraGTx and Hologen are forming a joint venture, called Hologen Neuro AI Ltd. In addition to the $200 million upfront payment to MeiraGTx, the joint venture, Hologen Neuro AI Ltd, will be funded with committed capital of up to $230 million from Hologen to fully finance the development of AAV-GAD for the treatment of Parkinson’s disease through to commercialization, as well as funding earlier stage clinical programs in the CNS, including AAV-BDNF for genetic obesity. Hologen will contribute its proprietary multi-modal generative foundation models (LMMs) to the joint venture. In forming this joint venture, MeiraGTx and Hologen have created the first neuro-AI clinical drug development company in which pioneering technologies from both companies will be deployed to transform the discovery and development of therapies targeting CNS circuitry in neurodegenerative and neuropsychiatric disorders. MeiraGTx will retain 30% ownership in the Hologen Neuro AI Ltd joint venture and will lead all clinical development and manufacturing. MeiraGTx will also enter into exclusive clinical and commercial manufacturing supply agreements with the joint venture. In addition, Hologen will own a minority stake in MeiraGTx’s manufacturing subsidiary and will contribute to the annual funding of the manufacturing subsidiary. Hologen is deploying its generative AI capabilities to further optimize MeiraGTx’s proprietary manufacturing capabilities by utilizing MeiraGTx’s unique data lakes built over 9 years of development of MeiraGTx’s manufacturing platform process. MeiraGTx’s AAV-GAD program for Parkinson’s disease is Phase 3 ready with commercial manufacturing ongoing in-house at MeiraGTx. The Company reported positive data from its randomized, sham-controlled clinical bridging study of AAV-GAD in October 2024, showing significant improvement of 18 points in Unified Parkinson’s Disease Rating Scale (UPDRS) Part 3 in the high dose group at 26 weeks, as well as significant improvement in the Parkinson’s Disease Questionnaire (PDQ-39) score, a key quality of life measure, for both the high and low dose groups at 26 weeks. This is the second double blind sham-controlled study of AAV-GAD in Parkinson’s disease to show a statistically significant benefit on UPDRS Part 3, as well as other validated clinically meaningful endpoints. Alexandria Forbes, Ph.D., co-founder, president and CEO of MeiraGTx stated, “We are delighted to be entering into this transformative collaboration with Hologen. Our initial focus is to increase the robustness, efficiency and probability of success of the AAV-GAD Phase 3 clinical study. The use of Hologen’s AI to elucidate brain circuitry in this complex heterogeneous disease has already significantly de-risked the AAV-GAD Phase 3 program when applied to MeiraGTx’s Phase 2 clinical data sets and has identified disease modifying changes in the physiology of the brain in response to AAV-GAD treatment.” Dr. Forbes continued, “Our collaboration with Hologen has broad significance for MeiraGTx and for drug development for neurological disorders in general. Deploying Hologen’s LMMs on MeiraGTx’s clinical data allows the characterization of disease modification in the CNS with unprecedented fidelity. This collaboration joins two incredibly innovative technologies to advance the potential for the development of drugs that have meaningful impact on neurodegenerative and neuropsychiatric diseases which have been largely intractable to effective treatment to date.” Dr. Forbes added, “From a financial perspective, this is a transformative transaction for MeiraGTx, providing $200 million in cash to MeiraGTx and at the same time funding a proportion of our internal manufacturing capabilities, as well as providing the additional capital into the newly established joint venture to fully finance the AAV-GAD program, while MeiraGTx retains significant equity value in the fully funded late-stage Neuro-AI company. The upfront capital will meaningfully extend MeiraGTx’s cash runway while allowing us to further expedite our pivotal AAV-hAQP1 Xerostomia program for which we received an RMAT designation in December 2024. We also expect this funding to help us accelerate the development of our Riboswitch technology supported by our compelling data in metabolic disease, cell therapy, neuropathic pain and heart disease - all very large areas of medical need amenable to phasic in vivo delivery of native biologic therapeutics.” Collaboration Details and Financial Terms: MeiraGTx will receive $200 million in upfront cash consideration at closing. MeiraGTx and Hologen will form a joint venture, Hologen Neuro AI Ltd, with additional committed funding into the joint venture of up to $230 million from Hologen to finance the development of the AAV-GAD program in Parkinson’s disease through to commercialization, as well as other locally-delivered therapies to the CNS. The joint venture, Hologen Neuro AI Ltd, will use Hologen’s proprietary multi-modal generative foundation models (LMMs). MeiraGTx will hold a 30% ownership in the joint venture and will lead all clinical development and manufacturing. Hologen Neuro AI Ltd will enter into both clinical and commercial manufacturing supply agreements with MeiraGTx for exclusive manufacturing of AAV-GAD and other locally-delivered genetic medicines targeting the CNS. Hologen will own a minority stake in MeiraGTx’s manufacturing subsidiary and will contribute a portion of the annual funding and deploy Hologen’s world leading generative AI capabilities to further accelerate the optimization of MeiraGTx’s proprietary manufacturing capabilities. The transactions described above are subject to customary closing and funding conditions, including the receipt of the clearances and approvals applicable to the proposed transactions under the foreign direct investment laws of the United Kingdom and the satisfaction or waiver of certain other closing conditions, and is expected to close in the second calendar quarter of 2025.
