Korneuburg, Austria, October 20, 2021 - Marinomed Biotech AG (VSE:MARI), a globally operating biopharmaceutical company, announced today a new collaboration and licensing agreement with Luoxin Pharmaceutical Group Stock Co., Ltd. (Stock Code: 002793.SZ, hereinafter referred to as "Luoxin Pharmaceutical"), one of the leading pharmaceutical companies in China. Luoxin Pharmaceutical will further develop and commercialize Budesolv for the treatment of allergic rhinitis in mainland China, Hong Kong, Macau, and Taiwan. Budesolv, a new formulation of the glucocorticoid budesonide, is the first medication originating from Marinomed's proprietary Marinosolv platform. Budesolv has successfully completed a pivotal Phase III clinical study, necessary for marketing authorization in Europe. The agreement to commercialize Budesolv in Greater China, is Marinomed's important next milestone on the communicated development path of the Marinosolv technology platform.

Luoxin Pharmaceutical will co-develop Budesolv for the Chinese markets and will be responsible for clinical development and obtaining the Chinese marketing authorization. This comprises building production capacities, holding the exclusive distribution rights, as well as ultimately being responsible for manufacturing and marketing Budesolv. Under the terms of the agreement, Marinomed will receive an upfront payment of USD 2 million, however, due to legal and corporate finance advisory fees with limited impact on current year's profit and loss statement. Depending on the achievement of specified development, regulatory and commercial milestones, Marinomed is eligible to receive double-digit million US-Dollar milestone payments as well as royalties on Budesolv sales in Greater China.

"We are fortunate to have Luoxin Pharmaceutical as such an outstandingly experienced and knowledgeable partner in China and are proud to have achieved this milestone agreement based on our Marinosolv platform. Budesolv is our first medication developed with the patented platform. Through Budesolv, we aim to revolutionize the treatment of allergic rhinitis. With an 85 % reduced dose and rapid efficacy onset within three hours, our new formulation can even be used for patent extension and further protection," said Dr. Andreas Grassauer, Marinomed's CEO. "The Budesolv example illustrates the immense potential of the Marinosolv platform, facilitating drug delivery and enhancing bioavailability. The Marinosolv platform holds great promise and will further fuel our development pipeline. This first licensing agreement is an important commercial validation and underlines the increasing recognition for our Marinosolv technology."

"We are looking forward to co-developing and marketing Budesolv in the Chinese market. To date, the collaboration with the Marinomed team has been excellent and we are confident that our co-development with their outstanding scientific team will be very fruitful," said Mr. Ryan Liu, Chairman of Luoxin Pharmaceutical.

About Budesolv:
Budesolv is the most advanced product from the Marinosolv^(R) platform to date. Budesolv is a novel aqueous and preservative-free formulation containing the corticosteroid Budesonide. The recent pivotal clinical trial was successfully completed, demonstrating non-inferiority of the Budesolv nasal spray when compared to Rhinocort^(R) Aqua 64. Furthermore, the trial demonstrated that with Budesolv an 85 % reduced dosage was equally effective and showed a significantly faster onset of action (Zieglmayer P et al., Clin Exp Allergy 2020). Filing for the European marketing authorization application is currently being prepared by Marinomed. For further publications on Budesolv, please visit .

About Marinosolv^(R):
Marinosolv^(R) is an innovative technology platform that enables solubilization of many barely soluble compounds and in consequence, opens new possibilities in treating a multitude of diseases. While organic compounds could previously often only be delivered as a suspension, Marinosolv^(R) provides aqueous formulations without preservatives with a faster onset of action and increased local bioavailability. In addition, they can be used without prior shaking, thus improving usability and enabling reliable dosing in sensitive tissues such as eyes or nose. Overall, the use of the Marinosolv^(R) technology can facilitate efficient drug delivery with high local availability and low systemic off-target activity. Even off-patent active ingredients can be patented as part of new formulations developed using Marinosolv^(R), while keeping production processes cost-efficient.
