- H2 2022: Assuming such initiation, the Phase 2a clinical trial results would be anticipated in H2 2022, which, if positive, could provide proof of concept data informing ACER-801 dosing and a development path forward in patients with iVMS
- EDSIVO™ (celiprolol)
- Q2 2022: If SPA agreement is reached with FDA, in Q2 2022 Acer intends to initiate the pivotal Phase 3, randomized, double-blind, placebo-controlled, decentralized clinical trial for EDSIVO™ for patients with COL3A1+ vEDS, subject to additional capital.

- ACER-2820 (emetine)
- Ongoing: Further advancement of the emetine program for treatment of certain viruses, including cytomegalovirus, zika, dengue, ebola, and COVID-19, is dependent on Acer’s ability to raise non-dilutive capital for this program
Q4 and Full Year 2021 Financial Results
Cash position. Cash and cash equivalents were $12.7 million as of December 31, 2021, compared to $5.8 million as of December 31, 2020. Acer believes its cash and cash equivalents available as of December 31, 2021, plus the $5.0 million second tranche of the Second Development Payment received on January 14, 2022 per the Relief Collaboration, will be sufficient to fund its currently anticipated operating and capital requirements into mid-2022, excluding support for the planned ACER-001 (MSUD), ACER-801 and EDSIVO™ clinical trials.
Research and Development Expenses. Research and development expenses were $1.7 million, net of collaboration funding of $1.3 million, for the three months ended December 31, 2021, compared to $3.5 million for the three months ended December 31, 2020. Research and development expenses for the three months ended December 31, 2021 were comprised of $1.1 million related to ACER-001, offset by $1.3 million of collaboration funding; $0.7 million related to ACER-801; $0.7 million related to EDSIVO™; $0.1 million related to ACER-2820; and $0.4 million related to other development activities. Research and development expenses were $6.5 million, net of collaboration funding of $6.1 million, for the year ended December 31, 2021, as compared to $11.8 million for the year ended December 31, 2020. This decrease of $5.3 million was primarily due to the recognition of $6.1 million of the collaboration funding from the Relief Collaboration, as well as a decrease in contract research expenses, partially offset by increases in employee-related expenses, regulatory and filing fees, and expenses for consulting and professional services.
General and Administrative Expenses. General and administrative expenses were $3.1 million, net of collaboration funding of $1.6 million for the three months ended December 31, 2021, compared to $2.7 million for the three months ended December 31, 2020. General and administrative expenses were $10.7 million, net of collaboration funding of $3.2 million, for the year ended December 31, 2021, as compared to $11.0 million for the year ended December 31, 2020. This decrease of $0.3 million was primarily due to the recognition of $3.2 million of the collaboration funding from the Relief Collaboration as well as a decrease in legal and consulting expenses, partially offset by increases in employee-related expenses and in precommercial activities.
Net Loss. Net loss for the three months ended December 31, 2021 was $4.4 million, or $0.31 net loss per share (basic and diluted), compared to a net loss of $6.2 million, or $0.50 net loss per share (basic and diluted), for the three months ended December 31, 2020. Net loss for the year ended December 31, 2021 was $15.4 million, or $1.08 loss per share (basic and diluted), compared to a net loss of $22.9 million, or $2.06 loss per share (basic and diluted), for the year ended December 31, 2020.
