Draft Registration Statement on Form S-1

 

 

Submitted July 24, 2020

 

 

CIK No. 0001620463

 

 

Ladies and Gentlemen:

 

On behalf of our client, Athira Pharma, Inc. (the “Company”), we submit this letter in response to comments from the staff (the “Staff”) of the Securities and Exchange Commission (the “Commission”) contained in its letter dated August 20, 2020, relating to the above-referenced Draft Registration Statement on Form S‑1 (the “Draft Registration Statement”).  On behalf of the Company, we are concurrently publicly filing via EDGAR a revised draft of the Registration Statement (the “Registration Statement”).

In this letter, we have recited the comments from the Staff in italicized, bold type and have followed each comment with the Company’s response. Except for page references appearing in the headings and Staff comments below (which are references to the Draft Registration Statement), all page references herein correspond to the pages of the Registration Statement.

Prospectus Summary
Overview, page 1

1.

We note statements throughout the prospectus that imply efficacy, such as "[n]onclinical studies and Phase 1 clinical trials with ATH-1017 demonstrated improvements in brain network activity indicating positive effects on brain function," "multiple dosing of ATH-1017 significantly improved brain activity" in AD subjects, ATH-1017 "normalized the P300 latency of AD subjects in a Phase lb clinical trial," "data indicate ATH-1017 treatment has recovered disruptions to brain function and network connectivity, likely through several components of the mechanism, including NMDA receptor modulation, increased connectivity through recovery of synaptic density, and overall improvement in neuronal health and function," and a large magnitude improvement in P300 latency that was observed for ATH-1017 is "expected to produce a correlated cognitive improvement." These are just examples. Please revise your disclosure throughout your prospectus to revise these and similar statements to eliminate conclusions or predictions that your product candidates are or will be effective as determinations of efficacy are solely within the authority of the FDA. You may provide a summary of the

objective data from your trials in the Business section where full and proper context can be provided without including conclusions related to efficacy.

In response to the Staff’s comment, the Company has revised its disclosures on pages 1, 4, 88 and 128 of the Registration Statement. With respect to the other above referenced statements, the Company respectfully submits that they are not statements that imply efficacy, but are rather factual descriptions of qEEG and P300 latency results from the Phase 1 trial. For example, on page 1 of the Registration Statement, the Company states “Nonclinical studies and Phase 1 clinical trials with ATH-1017 demonstrated improvements in brain network activity indicating potentially positive effects on brain function. In the AD subjects, multiple dosing of ATH-1017 significantly improved brain activity as measured by P300 latency, a functional measure that is highly correlated with cognition.” We respectfully submit that the second sentence of this disclosure, as revised, adequately clarifies that the improvements in brain network activity are based on the measurements of P300 latency, and not a conclusion as to the efficacy of ATH-1017.

P300 latency is a well-established objective measure that reflects the cognitive state, and is prolonged in patients with cognitive impairment such as AD. The P300 signal is generated by a neuronal network across several brain regions as cognitive processing occurs. Disruptions to neuronal health and synaptic function lead to disruptions in the network and result in prolonged (or worsening) P300 latencies and reduced cognitive processing in AD and other dementing conditions. Our data demonstrate an improvement in the prolonged P300 latencies in AD patients upon ATH-1017 treatment, suggesting that treatment improved brain function (cognitive processing) because the direction of change was towards historically established P300 latency values for healthy individuals. Similar to P300 latency, qEEG measures, which are generated by synchronous neuronal activity across networks, are also disrupted in AD patients due to impaired brain function and AD patients display reduced gamma power. Our data demonstrate an increase in gamma power, suggesting an improvement in the ability of the neuronal networks to generate gamma waves in patients with reduced gamma activity.

2.

We note your disclosure in this section and in the Business section that you plan to initiate a "pivotal" Phase 2/3 clinical trial for ATH-1017, LIFT-AD. We also note your statement on page 129 that LIFT-AD will need to achieve a statistically significant improvement separately on both the ADAS-Cog-11 and ADCS-CGIC in order to be considered a pivotal trial supportive of FDA approval for mild to moderate AD. Please revise the disclosure in these sections to make it clear that even if you receive positive data from LIFT-AD, you cannot be certain that the FDA or other regulators will find such data sufficient for approval of ATH-1017 or will not require you to conduct additional trials. Please also expand your disclosure to briefly explain what ADAS-cog, ADAS-cog-11 and ADCS-CGIC stand for the first time that each term is used in the prospectus.

In response to the Staff’s comment, the Company has revised its disclosures on pages 5 and 131 of the Registration Statement, as well as on pages 8, 120, 131 and elsewhere.

Our Pipeline and ATH Platform, page 3

3.

We note that you have included in your pipeline table ATH-1019, ATH-1018 and ATH-Discovery, all of which are in the discovery phase. Given the early-stage development of these programs, please explain why each program is sufficiently material to your business to warrant inclusion in your pipeline table. Please also remove the shaded portions of the lines in your pipeline table so that your pipeline table accurately reflects the current stage of development for each indication for ATH-1017 and remove the second line for the AD indication. Please clarify in footnote 3 whether you have already filed an IND for ATH-1017 for the treatment of PDD. Given that you have not yet initiated Phase 3 clinical trials for any of your product candidates, please also revise your statement that you are a "late" clinical-stage biopharmaceutical company throughout the prospectus.

In response to the Staff’s comment, the Company has revised its pipeline table and related disclosures on pages 3, 89, and 108 of the Registration Statement to remove the reference to ATH-Discovery, the shaded portions of the lines in the table, and the second line for the AD indication and to add clarifying disclosure regarding ATH-1017 for the treatment of PDD. We respectfully advise the Staff that ATH-1018 and ATH-1019 have progressed beyond discovery phase. ATH-1018 and ATH-1019 are lead compounds that have been identified through rigorous screening efforts in which they have demonstrated the ability to significantly activate the target HGF/MET system, and have displayed desired drug-like characteristics including oral bioavailability, stability, and optimized pharmacokinetics. They have shown positive effects in relevant preclinical models, indicating in vivo activity. ATH-1018 and ATH-1019 are advancing to additional in vivo testing towards INDs. In addition, we would draw the Staff’s attention to page 78 of the Registration Statement where the Company intends to disclose that a significant portion of the use of proceeds from the offering contemplated by the Registration Statement will be dedicated to development activities related to ATH-1018 and ATH-1019. We respectfully submit that each program is material to the Company’s business and an investor’s understanding of the Company’s prospects and therefore warrants inclusion in the pipeline table. In addition, we respectfully submit that the description of the Company as a “late” clinical stage biopharmaceutical company is appropriate. It is common practice for a biopharmaceutical company that has initiated a clinical trial that may be sufficient to support approval to be referred to as “late” clinical stage. Based on its discussions with the U.S. Food and Drug Administration, the results of the LIFT-AD trial could potentially support the approval of ATH-1017, if the trial results provide evidence that ATH-1017 is both effective and safe for the proposed indication. The Company expects to initiate the Phase 2/3 LIFT-AD clinical trial in early September and anticipates including disclosure to that effect in a future amendment to the Registration Statement.

Our Strategy, page 5

4.

We note your disclosure here and in the Business section that your strategy is to "rapidly advance" ATH-1017 through clinical development for AD and to initiate two clinical trials for AD by the end of 2020 in order to "accelerate [y]our development timelines." Please revise this disclosure to remove any implication that you will be successful in commercializing your product candidates in a rapid or accelerated manner as such statements are speculative. In this regard, we note your disclosure that your product candidates are based on new approaches and novel technology, which makes it difficult to predict the time and cost of product candidate development and the regulatory approval process.

In response to the Staff’s comment, the Company has revised its disclosures on pages 5 and 108 of the Registration Statement.

Implications of being an emerging growth company, page 10

Our Collaboration and Grant Agreements
Washington State University Research Foundation License Agreement and Amended and Restated Washington State University License Agreement, page 137

13.

Please disclose the royalty term and termination provisions for the amended and restated license agreement and file the agreement as an exhibit or explain the basis for your determination that it is not required to be filed. We also note that your licensed patents under this agreement include WSU's rights to a patent jointly owned with Pacific Northwest Biotechnology, Inc. Please discuss whether you expect this joint ownership to have any effect on your license of the patent or your development of the product candidate to which the patent relates.

In response to the Staff’s comment, the Company has revised its disclosure on page 141 of the Registration Statement to include disclosure regarding the termination provisions of the WSU license agreement and has filed the agreement as an exhibit to the Registration Statement. We would respectfully draw the Staff’s attention to page 91 of the Registration Statement, where the Company discloses that it is obligated to pay WSU a royalty in the mid-single digits of net sales. We respectfully submit that this disclosure is adequate for an investor to assess the WSU license agreement and that additional disclosure would not be material to an investor and would be competitively harmful to the Company. The Company does not expect the joint ownership of the patents included in the WSU license agreement to materially affect the licenses of such patents or the development of any of the Company’s product candidates.

Financial Statements
Notes to Financial Statements
7. Significant Agreements, page F-15

15.

Please clarify how you determined that the grant liability is an eligible item under ASC 825-10-15-4. If applicable, describe how the grant liability meets the definition of a financial liability.

The Company respectfully advises the Staff that terms of the contracts with the Washington Life Sciences Discovery Fund (“LSDF”) provide LSDF the right to receive cash payments upon the occurrence of expected triggering events, each of which is disclosed on page F-15 of the Registration Statement. In assessing whether the contracts with LSDF met the definition of a financial liability, the Company considered whether LSDF would receive creditor rights in the event of a liquidation of the Company. The Company believes that LSDF would be considered as a creditor in the event of a liquidation and therefore, the contracts embody a liability thereby precluding classification as a component of stockholders’ equity. The definition of a financial liability includes “an obligation on one entity to deliver cash or another financial instrument to a second entity” and LSDF’s creditor rights impose such an obligation on the Company. Accordingly, the Company concluded that the contracts with LSDF met the definition of a financial liability.

To determine the accounting for the grant liability, the Company considered the scope exceptions from fair value accounting included in ASC 825-10-15-4 and noted that the grant liability did not meet any of the scope exceptions. Therefore, the Company made the election to account for the grant liability at fair value with changes in fair value recognized as a component of earnings at the end of each reporting period.
