Preliminary Price Range

The Company advises the Staff that the Company currently expects a price range of $[***] to $[***] per common share (the “Preliminary Price Range”) for its initial public offering (“IPO”), which Preliminary Price Range reflects a [***]-for-[***] reverse share split of the Company’s shares that will be effected prior to the effectiveness of the Registration Statement. This Preliminary Price Range implies a pre-money valuation range for the Company of $[***] million to $[***] million. The share and per-share numbers in this letter are presented on a post-split basis.

The Preliminary Price Range is based in part upon the Company’s prospects, prospects for the biopharmaceutical industry, the general condition of the securities markets and the recent market prices of, and the demand for, publicly traded shares of generally comparable companies in the biopharmaceutical industry, as well as input received from Jefferies LLC, Cowen and Company, LLC and Piper Jaffray & Co., the lead underwriters (the “Representatives”) for the IPO. The Company notes that, as is typical in IPOs, the Preliminary Price Range was not derived using a formal determination of fair value, but was determined by discussions between the Company and the Representatives based on the assessment of the foregoing factors.

The Company will include a narrower bona fide price range of the common shares in an amendment to the Registration Statement that will precede the commencement of the Company’s road show, which the Company expects to be a two-dollar range within the Preliminary Price Range. However, the parameters of the bona fide price range will be subject to then-current market conditions, continuing discussions with the Representatives and material business developments impacting the Company, and due to the volatility in the securities markets, in particular the volatility experienced in the market by recent IPO issuers, there is a possibility that the bona fide price range for the IPO may fall outside of the Preliminary Price Range. In any event, the Company confirms to the Staff that the bona fide price range will comply with Item 501(b)(3) of Regulation S-K and C&DI 134.04.

Common Share Valuation Methodologies

As there has been no public market for the Company’s common shares to date, the estimated fair value of its common shares has been determined by the Company’s board of directors (the “Board”), as of the date of each option grant, with input from management, considering the Company’s most recent arm’s-length sales of its preferred shares and the most recent third-party valuation of its common shares, as well as the Board’s assessment of additional objective and subjective factors that the Board believed were relevant and which may have changed from the date of the most recent third-party valuation through the date of the grant. The Board considered various objective and subjective factors to determine the fair value of the common shares as of each grant date, including:

·                  the prices at which the Company sold preferred shares and the superior rights and preferences of the preferred shares relative to the common shares at the time of each grant;

·                  the progress of the Company’s research and development programs, including the status and results of clinical trials for etripamil;

·                  the Company’s stage of development and its business strategy;

·                  external market conditions affecting the healthcare industry in general, and the biopharmaceutical industry in particular, and trends within such industries;

·                  the Company’s financial position, including cash on hand, and its historical and forecasted performance and operating results;

·                  the lack of an active public market for the common shares and preferred shares;

·                  the likelihood of achieving a liquidity event, such as an IPO, in light of prevailing market conditions;

·                  the Company’s IPO timeline and related activities; and

·                  the analysis of IPOs and the market performance of similar companies in the healthcare and biopharmaceutical industries.

The third-party valuations of the Company’s common shares that the Board considered in making its determinations were prepared in accordance with the American Institute of Certified Public Accountants Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation (the “Practice Guide”), which prescribes several valuation approaches for determining the value of an enterprise, such as the cost, market and income approaches, and various methodologies for allocating the value of an enterprise to its capital structure and specifically its common shares.

In accordance with the Practice Guide, the Company considered the following methods for allocating the enterprise value across its classes and series of shares to determine the estimated fair value of its common shares at each valuation date.

·                  Option Pricing Method (OPM). The OPM estimates the value of the common equity of the Company using the various inputs in the Black-Scholes option pricing model. The OPM treats the rights of the holders of common shares as equivalent to that of call options on any value of the enterprise above certain break points of value based upon the liquidation preferences of the holders of the Company’s convertible preferred shares, as well as their rights to participation, and the share prices of the outstanding options. Thus, the value of the common shares can be determined by estimating the value of its portion of each of these call option rights. Under this method, the common shares have value only if the funds available for distribution to shareholders exceed the value of the liquidation preference at the time of a liquidity event, such as a merger or sale. Given the common shares represent a non-marketable equity interest in a private enterprise, an adjustment to the preliminary value estimates had to be made to account for the lack of liquidity that a shareholder experiences. This adjustment is commonly referred to as a discount for lack of marketability (“DLOM”).

·                  Probability-Weighted Expected Return Method (PWERM). The PWERM is a scenario-based analysis that estimates the value per share based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes considered by the Company, as well as the economic and control rights of each share class.

·                  Current Value Method (CVM). The CVM allocates equity by subtracting the liquidation preference of any outstanding preferred shares considering all rights and assumed conversion behavior associated with those shares.

·                  Hybrid Method. The Hybrid Method is a weighted-average method that combines the CVM, OPM and PWERM. Weighting allocations are assigned to the CVM, OPM and PWERM, factoring in possible future liquidity events.

In order for the Board to determine the estimated fair value of the common shares, the OPM was utilized for the independent third-party valuation of the Company’s common shares as of July 31, 2017 (the “July 2017 Valuation”) discussed below. The Hybrid Method was utilized for the independent third-party valuations of the Company’s common shares as of August 15, 2018 (the “August 2018 Valuation”),  as of October 23, 2018 (the “October 2018 Valuation”) and as of January 31, 2019 (the “January 2019 Valuation”), each discussed below, because at those times the Company had better visibility into the

timing of a potential IPO. As noted below, equity value for each liquidity event scenario was weighted based on a probability of each event’s occurrence. In each of the IPO scenarios discussed below, the Company assumed that all outstanding convertible preferred shares would be converted into common shares. In the sale of the Company scenario, the Company allocated the value per share by taking into account the liquidation preferences and participation rights of the convertible preferred shares consistent with the method outlined in the Practice Guide.

At each grant date, the Board evaluated any recent events and their potential impact on the estimated fair value per common share. For grants of share awards made on dates for which there was no contemporaneous independent third-party valuation, the Board determined the estimated fair value of the common shares on the date of grant taking into consideration the immediately preceding valuation report as well as other pertinent information available to it at the time of the grant. In connection with the July 2017 Valuation, the Company considered the most recent arm’s length preferred share financings prior to the issuance of any option grants as the basis for the value of its common shares at the date of the option grant. After the July 2017 Valuation, the valuation methodology was changed to the use of a Hybrid Method incorporating the CVM, OPM and PWERM, as the Company had obtained better visibility into the near-term timing of a potential IPO, but still considered the uncertainty surrounding the Company’s valuation in the event an IPO did not occur. The Hybrid Method is commonly used in these types of scenarios and is consistent with guidance from the Practice Guide.

July 2017 Valuation and May 2018 Option Grants

On May 31, 2018, the Company granted options to purchase a total of [***] common shares at an exercise price of $[***] per share. The Board determined the estimated fair value of the common shares at the time of the grants was $[***] per share based on a number of factors, including the July 2017 Valuation, which determined that the estimated fair value of the common shares was $[***] per share. For the period from the July 2017 Valuation to May 31, 2018, the Board determined there were no internal or external developments since the July 2017 Valuation that warranted a change in the estimated fair value of the common shares. For the July 2017 Valuation, the Company utilized the OPM to derive the implied equity value for the Company. For purposes of the July 2017 Valuation, an option-based analysis was performed in an effort to estimate the appropriate DLOM for the common shares. A DLOM of 25% was used for the July 2017 Valuation. The July 2017 Valuation reflected the closing of the Company’s Series C preferred share financing in July 2017, and the May 2017 presentation of results from its Phase 2 trial
