Regulatory News:

Aptorum Group Limited (Nasdaq: APM, Euronext Paris: APM) (“Aptorum Group” or “We”), a clinical stage biopharmaceutical company dedicated to meeting unmet medical needs in oncology, autoimmune diseases and infectious diseases, today announced financial results for the fiscal year ended December 31, 2022, and provided an update on clinical and corporate developments.

Mr. Darren Lui, Chief Executive Officer and Executive Director of Aptorum Group, commented “Aptorum’s operational plans remain on track. In particular, our lead projects, ALS-4 (targeting infections caused by Staphylococcus aureus including Methicillin-resistant Staphylococcus aureus (MRSA)) and SACT-1 (targeting neuroblastoma), have completed their Pre-IND discussion and End of Phase 1 meeting, respectively, with US FDA. We are working towards completion of regulatory clearance regarding next stage of clinical trials for these 2 lead projects in the United States and further explore ALS-4 in non-human applications. PathsDx is continuing its validations and we are targeting to generate further data to support the planned commercialization efforts of PathsDx and facilitate external strategic collaborations. NativusWell^® has also commenced commercialization in China through JD.com, one of the largest e-commerce platforms in China.”

Clinical Pipeline Update and Upcoming Milestones

In 2023, we announced a number of updates for our lead and other projects:

- Our ALS-4 (a first in-class anti-virulence based small molecule drug targeting infections caused by Staphylococcus aureus, including, but not limited to Methicillin Resistant Staphylococcus Aureus (“MRSA”)) Pre-IND discussion with the US Food and Drug Administration (“US FDA”) is completed. Upon the completion of ALS-4’s respective Phase I clinical trials in Canada, ALS-4 has been targeting to obtain the necessary IND clearance for Phase II clinical trials in the United States. The Pre-IND discussions with US FDA focused on overall development plan in preparation for the IND application of ALS-4 targeting Acute Bacterial Skin and Skin Structure Infections (ABSSSI) initially. With the positive feedback on the overall development strategy from the US FDA, Aptorum is now proceeding towards obtaining IND clearance of ALS-4.

- Our SACT-1 (a repurposed small molecule drug targeting Neuroblastoma and potentially other cancer types) End of Phase 1 (“EOP1”) meeting with USFDA is completed. The EOP1 meeting was focused on gaining alignment with the US FDA regarding the clinical and regulatory pathway for SACT-1 for the treatment of neuroblastoma in pediatric patients aged 2-18. At the EOP1, the FDA generally agreed with the chemistry-manufacturing-control (CMC) strategy and our proposed clinical development plan for Phase 1/2 trials.

- Our NativusWell^® (a new dietary supplement supporting women’s health throughout the Menopausal cycles) has commenced collaboration with one of the largest e-commerce platforms in China, JD.com, and NativusWell^® is now distributable in China via JD (also known as Jingdong).

- Our PathsDx (a liquid biopsy NGS based technology for the diagnosis of infectious diseases) continues its validation to generate further supporting data prior to its eventual commercialization.

Fiscal Year End Financial Results

Aptorum Group reported a net loss of $11.5 million in 2022, as compared to $27.1 million in 2021. The decrease in net loss were mainly driven by the gain on long-term investments of $5.6 million, and decrease in loss on investments in marketable securities, net of $7.9 million.

Research and development expenses were $9.2 million in 2022 as compared to $10.9 million in 2021. The decrease in research and development expenses in 2022 was mainly due to the decrease in contracted research organizations services as we are in a planning process for Phase 2 of our lead projects which does not require many services from contracted research organizations.

General and administrative fees were $5.2 million in 2022 as compared to $5.4 million in 2021. The decrease in general and administration fees was mainly due to decrease in payroll expenses due to decrease in number of staff.

Legal and professional fees were $2.9 million in 2022 as compared to $2.6 million in 2021. The increase in legal and professional fees was mainly due to more consulting services engaged during 2022.

Aptorum Group reported $5.0 million of cash and restricted cash as of December 31, 2022 compared to $8.3 million as of December 31, 2021. The decrease in cash and restricted cash was mainly the cash used in operating activities of $11.5 million, partly offset by the repayment of loan from related parties of $3.0 million, loan from a bank of $3.0 million, and proceeds from issuance of convertible notes of $3.0 million in 2022.
