Regulatory News:

MaaT Pharma (EURONEXT: MAAT – the “Company”), a French clinical-stage biotech and a pioneer in the development of microbiome-based ecosystem therapies dedicated to improving survival outcomes for patients with cancer today reported its cash position as of March 31, 2022, and its revenues for the first quarter of 2022.

Over the course of the first quarter 2022, the Company has continued its clinical development as previously announced in the context of its IPO in November 2021 such as:

- In January 2022, announcement of positive interim and preliminary data of its Phase 1b trial for MaaT033 in preventing complications of allogeneic hematopoietic stem cell transplantation

- In March 2022, inclusion of the first patient in a Phase 3 trial “ARES” for drug-candidate MaaT013 in the treatment of Graft-versus-Host Disease

- In April 2022, initiation of a Phase 2a trial, sponsored by AP-HP, evaluating MaaT013 in combination with immune checkpoint inhibitors for patients with melanoma

Moreover, the Company entered a partnership agreement in February 2022 with Skyepharma to build, to date, France’s largest cGMP manufacturing facility exclusively dedicated to the production of Microbiome Ecosystem Therapy (MET), thus increasing MaaT Pharma’s manufacturing capabilities ten-fold in line with supply needs required by 2030.

Cash position¹

As of March 31, 2022, total cash and cash equivalents were EUR 41.1 million, as compared to EUR 43.3 million as of December 31, 2021. The Company believes it has sufficient cash to cover needs of the development programs presented during the IPO up until the end of the third quarter of 2023.

Revenues in Q1 2022¹

MaaT Pharma reported revenues of EUR 0.3 million for the quarter ended March 31, 2022, compared with 0.1 million for the same period of 2021. Revenues correspond to compensation invoiced in relation to the compassionate access program, as approved by the French National Drug Safety Agency (Agence Nationale de Sécurité du Médicament or ANSM). In 2022, the program was fully active whereas in 2021 the program began over the course of the first quarter, thus explaining the year-on-year increase.
