The class of equity security to which this statement on Schedule 13D (this “Schedule 13D”) relates is the Common Stock, $0.0001 par value per share (the “Common Stock”), of Vincera Pharma, Inc., a Delaware corporation (f/k/a LifeSci Acquisition Corp. (“LSAC”)) (the “Issuer”). The address of the principal executive offices of the Issuer is 4500 Great America Parkway, Suite 100, #29, Santa Clara, CA 95054. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.

The Issuer is a clinical-stage biopharmaceutical company focused on leveraging its extensive development and oncology expertise to advance new therapies intended to address unmet medical needs for the treatment of cancer.

The Reporting Person serves as a professor of hematology at Ohio State University. The principal business address of the Reporting Person is 410 West 12th Ave., 405D, Columbus, OH 43210.

Pursuant to Instruction C of Schedule 13D, the name, business address, present principal occupation or employment, and the name, principal business and address of any corporation or other organization in which such employment is conducted for each of the persons who may be deemed to exert control over the Reporting Person is set forth in this Schedule 13D.

(d) and (e) During the last five years, the Reporting Person has not been convicted in any criminal proceedings (excluding traffic violations or similar misdemeanors) or been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of which such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

The shares of Common Stock reported herein as beneficially owned by the Reporting Person were acquired pursuant to that certain Merger Agreement, dated as of September 25, 2020 (the “Merger Agreement”), by and among LSAC, LifeSci Acquisition Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of LSAC (“Merger Sub”), VNRX Corp. (f/k/a Vincera Pharma, Inc.) (“Legacy Vincera Pharma”), a Delaware corporation, and Raquel E. Izumi, as the representative of the stockholders of Legacy Vincera Pharma. Pursuant to the terms of the Merger Agreement, Legacy Vincera Pharma in effect became a public company through a reverse merger whereby Merger Sub merged with and into Legacy Vincera Pharma (the “Merger” and, collectively with the other transactions described in the Merger Agreement, the “Business Combination”), with Legacy Vincera Pharma surviving the Merger and becoming a wholly-owned subsidiary of the Issuer with its name changed to VNRX Corp. The Business Combination closed on December 23, 2020 (the “Closing”).

Pursuant to the Merger Agreement, immediately prior to the effective time of the Merger (the “Effective Time”), each share of Legacy Vincera Pharma’s common stock, par value $0.0001 per share (the “Legacy Vincera Pharma Common Stock”) (other than any Dissenting Shares (as defined in the Merger Agreement)), was canceled and the stockholders of Legacy Vincera Pharma received (i) 0.570895 shares of Common Stock for each share of Legacy Vincera Pharma Common Stock held by them immediately prior to the Effective Time and (ii) certain rights to additional shares of Common Stock (the “Earnout Shares”) after the Closing, which Earnout Shares may be issuable from time to time.

Immediately prior to the Effective Time, 2,834,497 shares of Legacy Vincera Pharma Common Stock held by the Reporting Person were automatically converted into 1,618,199 shares of Common Stock. In addition, the Reporting Person may be eligible to receive up to 1,765,308 Earnout Shares, if any, that may be issuable from time to time. Pursuant to the terms of the Merger Agreement, the Earnout Shares will be released from escrow upon the achievement of certain earnout targets based upon the volume weighted average share price of Common Stock ranging from $20.00 to $45.00 per share. The number of Earnout Shares to be issued is subject to adjustment for any stock split, reverse stock split, recapitalization, reclassification, reorganization, exchange, subdivision or combination of the Issuer, pursuant to the terms set forth in the Merger Agreement.

The information contained above in Item 1 and Item 3 of this Schedule 13D is incorporated herein by reference. The Reporting Persons acquired the securities of the Issuer pursuant to the Merger Agreement.

The Reporting Person co-founded Legacy Vincera Pharma and was a director of Legacy Vincera Pharma through December 23, 2020.

Subject to the Lock-up Agreement described in Item 6 of this Schedule 13D, the Reporting Person may from time to time buy or sell securities of the Issuer as appropriate for the Reporting Person’s personal circumstances.

Except as described in this Schedule 13D, the Reporting Person does not have any present plans or proposals that relate to or result in any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, although, subject to the agreements described herein, the Reporting Person, at any time and from time to time, may review, reconsider and change his position and/or change his purpose and/or develop such plans and may seek to influence management of the Issuer or the Issuer’s Board of Directors (the “Board”) with respect to the business and affairs of the Issuer and may from time to time consider pursuing or proposing such matters with advisors, the Issuer or other persons.

(a), (b) The responses of the Reporting Person with respect to Rows 7 through 13 of the cover page to this Schedule 13D are incorporated herein by reference.

The Reporting Person’s aggregate percentage of beneficial ownership is approximately 21.5% of the outstanding shares of the Common Stock. Calculations of the percentage of the shares of Common Stock beneficially owned in this Schedule 13D assume that 13,984,441 shares of Common Stock are outstanding, based on information included in the Issuer’s Current Report on Form 8-K filed on December 30, 2020, and that the 1,765,308 shares of Common Stock that the Reporting Person is eligible to receive pursuant to the earnout rights discussed in this Schedule 13D are issued and outstanding. The Reporting Person has sole voting and dispositive power over the shares.

The Reporting Person expressly disclaims beneficial ownership of all of the shares of Common Stock included in this Schedule 13D, other than the shares of Common Stock held of record by such Reporting Person, and the filing of this Schedule 13D shall not be construed as an admission that any such person is, for the purposes of sections 13(d) or 13(g) of the Act the beneficial owner of any securities covered by this Schedule 13D.
