Regulatory News:

Aptorum Group Limited (NASDAQ:APM, Euronext Paris: APM))) ("Aptorum Group" or the "Company"), a clinical stage biopharmaceutical company dedicated to meeting unmet medical needs in oncology and infectious diseases, today provided a business update and announced financial results for the six months ended June 30, 2021.

"During the first half of 2021, we remained focused on advancing the development of our therapeutic programs. As announced in early 2021, our ALS-4 program (targeting infections caused by Staphylococcus aureus including MRSA) commenced a Phase 1 clinical study in Canada. We are pleased that 5 total cohorts, which represent the essential part of the single ascending dose ("SAD") portion of the trial, have been completed without any serious adverse events being observed. On the basis of ALS-4's favourable safety profile, we are commencing the multiple ascending dose ("MAD") portion of the trial in Q3, 2021. Our other lead program SACT-1 (targeting neuroblastoma), has also received clearance from the US FDA to commence clinical trials in the United States. SACT-1 will be our second therapeutic program entering into the clinical phase. Our RPIDD program (liquid biopsy based approach to infectious disease rapid diagnostics) is also progressing well and we are very pleased to continue its clinical validation currently in collaboration with A*Star. Finally, we are excited to continue with our efforts of commercialising our NativusWell^® DOI product, a novel supplement targeting woman's health including menopausal symptoms. We are also excited to continue to identify and progress on certain other potential novel therapeutic candidates, including our ongoing assessment of a number of novel immunomodulators developed by Yale University targeting major autoimmune diseases, as we announced earlier in the year," said Mr. Ian Huen, Chief Executive Officer and Executive Director of Aptorum Group Limited.

Clinical Pipeline Update and Upcoming Milestones

In September 2021, Aptorum Group received clearance from the US FDA to open an IND to conduct clinical trials on SACT-1, an orally administered small molecule repurposed drug for the treatment of neuroblastoma. The IND-opening study is a bioavailability/Food Effect study, followed by a Phase 1b/2a trial in neuroblastoma patients which is subject to further FDA approval.

In May 2021, Aptorum Group announced its ongoing Phase I clinical trial for one of its lead programs, ALS-4, an orally administered small molecule drug for the treatment of infections caused by Staphylococcus aureus including MRSA, under which two initial cohorts of the SAD portion of the trial in healthy male and female adult subjects have been completed with no serious adverse events observed. In July 2021, the Company further announced two additional cohorts (Cohort C & D) of the SAD portion have been completed with no serious adverse events observed. In total, up to 6 cohorts for SAD and 3 cohorts for MAD have been planned. The MAD study is commencing in Q3, 2021.

In May 2021, Aptorum Group entered into an agreement with Exeltis regarding Aptorum's preclinical asset targeting women's health and gynaecological conditions, including endometriosis, in the European Union and Latin America. Aptorum retained development rights in the rest of the world.

In April 2021, Aptorum Group entered into a material transfer and license option agreement with Yale University to evaluate a group of preclinical stage novel immunomodulators that could represent first-in-class therapeutics in treating autoimmune and oncology diseases, among other indications.

Corporate Highlights

In May 2021, Jurchen Investments Limited, purchased an aggregate of 1,387,925 of the Company's Class A Ordinary Shares at $2.882 per share, representing 10% premium to the last closing price.

On March 26, 2021, Aptorum Group entered into a Sales Agreement with H.C. Wainwright & Co., LLC, acting as the Company's sales agent, pursuant to which the Company may offer and sell, from time to time, through the Sales Agent, Class A Ordinary Shares for an aggregate offering price of up to $15,000,000.

Financial Results for the Six Months Ended June 30, 2021

Aptorum Group reported a net loss of $17.1 million for the six months ended June 30, 2021 compared to $7.0 million for the same period in 2020. The increase in net loss in the current period was driven by loss on investments in marketable securities, net of $7.6 million, and there was a gain on non-marketable investment of $1.6 million in the same period in 2020 while there was no such gain in current period.

Research and development expenses were $5.5 million for the six months ended June 30, 2021 compared to $4.3 million for the same period in 2020. The increase in research and development expenses was mainly due to the increase in services provided by contracted research organizations as a result of our projects' development.

General and administrative fees were $2.6 million for the six months ended June 30, 2021 compared to $2.1 million for the same period in 2020. The increase in general and administration fees was mainly due to a one-off reversal of over-provision in relations to bonus payables to our directors, employees, external consultants and advisors in the last period. It was partly offset by the decrease in travelling expenses due to the outspread of COVID-19 and the decrease in amortization and depreciation due to the disposal of fixed assets in the second half of 2020.

Legal and professional fees were $1.2 million for the six months ended June 30, 2021 compared to $1.5 million for the same period in 2020. The decrease in legal and professional fees was mainly due to the decrease in consultancy services during current period.

As of June 30, 2021, cash and restricted cash totalled approximately $20.1 million and total equity was approximately $26.5 million.

Aptorum Group expects that its existing cash and restricted cash together with undrawn line of credit facility from related parties, will enable it to fund its operating and capital expenditure requirements for at least the next 12 months.
