HALLE (SAALE), Germany, 28 March 2019 - Probiodrug AG (Euronext Amsterdam: PBD), a clinical stage biopharmaceutical company developing novel therapeutic solutions to treat Alzheimer’s disease (AD), today announced its financial results for the twelve-month period ending December 31, 2018, prepared in accordance with German GAAP (“HGB”) and on a voluntary basis, in accordance with IFRS as endorsed by the European Union. The Financial Statements are available on the company website (http://www.probiodrug.de/investors/reports-and-presentations/).

KEY HIGHLIGHTS

• PQ912 Phase 2b core program prepared
• Publication of new results of PQ912 pharmacology in peer reviewed journal
• Annual Shareholders’ Meeting held on June 21, 2018
• Expenditures and corresponding cash position in line with management expectations
• Cash and cash equivalents of EUR 3.8 million as of December 31, 2018 to provide, according to present projections, a cash reach through 3^rd quarter of 2019

POST PERIOD HIGHLIGHTS
In March 2019, Probiodrug announced a funding of the National Institutes of Health (NIH) totaling 15 million USD over four years.

The grant was awarded by the National Institute on Aging, part of the NIH, for the project “A Seamless Phase 2A-B Randomized Double-Blind Placebo-Controlled Trial to Evaluate the Efficacy and Safety of PQ912 in Patients with Early Alzheimer’s Disease”. The funding is under award number R01AG061146 to the University of California, San Diego. Probiodrug is the sponsor of the U.S. study led by study principal investigator Howard Feldman, MD, Director of the ADCS, a national consortium of clinical sites, based at the University of California, San Diego.

Commenting on the 2018 results, Dr. Ulrich Dauer, Chief Executive Officer of Probiodrug, said: “The overarching theme of the biopharma industry in 2018 can be expressed as a year of change. However, change is the catalyst of growth. Probiodrug followed the industry trend and experienced a change itself. The reorganization of the management team has allowed us to focus on the future funding of the company, while continuing the important work initiated by our predecessors - entering into the next stage of development for our lead candidate PQ912 and our company as a whole.”

FINANCIAL PERFORMANCE
Key Figures (according to IFRS)

Details of the Financial Results (according to IFRS)

Net loss
The operating loss improved to EUR 7,698k (2017: EUR 9,961k), mainly due to lower research and development expenses amounting to EUR 4,836k (2018: EUR 7,454k). General and administrative expenses amounted to EUR 2,891k (2017: EUR 2,511k). The net loss is slightly better than last year at EUR 7,737k (2017: EUR 8,009k) as 2017 included income from a tax gain in the amont of EUR 1,102k.

All expenditures are in line with the projections of Probiodrug.

Equity
The equity amounts to EUR 1,230k (2017: EUR 8,923k), leading to an equity ratio of 30.4%. In 2018, the share capital was unchanged at EUR 8,208k.

Cash
The cash flow used in investing activities showed proceeds from the expiration of a pension liabilities insurance in the amount of EUR 460k (2017: EUR 459k) and costs in intangible assets and equipment in the amount of EUR 16k (2017: EUR 8k). Cash and cash equivalents at year end 2018 were EUR 3,783k (2017: EUR 10,291k).

Noncurrent/ current liabilities
The noncurrent liabilities in the amount of EUR 1,854k (2017: EUR 1,171k) represent the net commitment (defined benefit liability) of the pension commitments (defined benefit obligations) of EUR 1,644k (2017: EUR 1,619k). The current liabilities increased and amount to EUR 964k (2017: EUR 668k) as at December 31, 2018. The trade payables amounting to EUR 772k (2017: EUR 344k) result from the ordinary course of business. They have a remaining term of up to one year.

NEW THERAPEUTIC APPROACH
Pipeline update
Probiodrug`s therapeutic approach targets pyroglutamate-Abeta (pGlu-Abeta, also called N3pG Abeta) as a therapeutic strategy to fight Alzheimer’s disease (AD). This modified Abeta is considered to be linked with disease initiation and progression by seeding the formation of soluble neurotoxic amyloid oligomers. Probiodrug is developing proprietary product candidates to target toxic pGlu-Abeta via two modes of action: by (i) inhibiting the production of pGlu-Abeta; and (ii) clearing existing pGlu-Abeta from the brain.

Probiodrug’s innovative approach is based on the development of specific inhibitors for the enzyme Glutaminyl Cyclase (QC), which is instrumental in the creation of pGlu-Abeta. In addition, the Company is developing a monoclonal antibody targeting pGlu-Abeta to enhance its clearance.

To date, Probiodrug’s pipeline consists of a small molecule inhibitor of the QC-enzyme, PQ912, and a monoclonal antibody, PBD-C06, targeting pGlu-Abeta.

PQ912
PQ912 is a first-in-class inhibitor of the QC enzyme that plays a central role in the formation of synaptotoxic pGlu-Abeta oligomers. Probiodrug reported in 2017 on the first clinical study with PQ912 in subjects with biomarker-proven AD. The aim of “SAPHIR”, a Phase 2a study, was to determine the maximal tolerated dose, target occupancy and treatment-related pharmacodynamic effects. The exploratory efficacy readouts selected were tailored to the patient population with early AD. The therapeutic approach focuses on synaptic dysfunction as captured by various measures such as electroencephalography (EEG), synaptic biomarkers and sensitive cognitive tests.

PQ912 treatment resulted in a significant reduction in QC activity, which resulted in an average target occupancy of > 90%. A significant reduction of theta power in the EEG frequency analysis and a significant improvement in the One Back test of our Neuropsychological Test Battery was observed. The exploratory biomarker readouts, neurogranin for synaptic toxicity and YKL-40 as a marker of inflammation, appear to be sensitive enough to serve as efficacy markers in the next Phase 2b study.

There was no significant difference between treatments in the number of subjects with (serious) adverse events, although there were slightly more patients with a serious adverse event in the PQ912 group compared to placebo. More subjects treated with PQ912 discontinued treatment due to adverse events, mostly related to gastrointestinal and skin/subcutaneous tissue disorders.
The maximal tolerated dose of PQ912 has been identified and the results support future studies at still lower doses reaching > 50% target occupancy, a longer up-titration phase to potentially induce adaptation and longer treatment periods to confirm the early signals of efficacy as seen in this study.

The study revealed a positive benefit to risk ratio of PQ912 and provides important guidance how to move forward in the development of PQ912 as a disease-modifying drug for AD. Altogether, the results make the program highly attractive for further development. The strategy for the Phase 2b and proof of concept program has been defined and the set-up phase of “SAPHIR 2” in Europe with Professor Philip Scheltens, Director of the Alzheimer Center VU University Medical Center Amsterdam, NL, again as Chairperson has commenced. A second complementary trial is in the planning phase, and will be run by Professor Howard Feldman, Director of ADCS in San Diego, USA.

PBD-C06
PBD-C06 is a monoclonal antibody, currently in preclinical stage. PBD-C06 targets pGlu-Abeta, aiming to selectively clear the brain of pGlu-Abeta while leaving non-toxic forms of Abeta untouched. PBD-C06 has been successfully humanized and also de-immunized to avoid detection by the patient’s endogenous immune system. In addition, the antibody was modified to reduce complement activation, which is assumed to be the cause for dose-limiting side effects (micro-bleed and micro-hemorrhage). For the first time for an anti-pGlu Abeta approach PBD-C06 has not only shown the ability to reduce Abeta/plaques but also to significantly improve cognitive deficits in aged AD-mice. Moreover, no evidence was found of increased micro-hemorrhages after treatment with PBD-C06.
