Item 1. Security and Issuer.

This Amendment No. 2 (“Amendment No. 2”) to Schedule 13D amends and supplements the statement on Schedule 13D originally filed on October 25, 2018, and Amendment No. 1 thereto filed on March 26, 2021, relating to the common stock, $0.001 par value (the “Common Stock”), of Marker Therapeutics, Inc. (the “Issuer”) having its principal executive office at 9350 Kirby Drive, Suite 300, Houston, Texas 77054.

Certain terms used but not defined in this Amendment No. 1 have the meanings assigned thereto in the Schedule 13D. Except as specifically provided herein, this Amendment No. 1 does not modify any of the information previously reported on the Schedule 13D.

This Amendment No. 2 is being filed to report that the beneficial ownership of Common Stock by the Reporting Persons (as defined below) has decreased by more than 1% as a result of an increase in the number of Common Stock outstanding and the Warrant Expiration.

Item 2. Identity and Background.

This statement is being filed by:

(a) New Enterprise Associates 16, L.P. (“NEA 16”), NEA Partners 16, L.P. (“NEA Partners 16”), which is the sole general partner of NEA 16; and NEA 16 GP, LLC (“NEA 16 LLC” and, together with NEA Partners 16, the “Control Entities”), which is the sole general partner of NEA Partners 16; and

(b) Forest Baskett (“Baskett”), Ali Behbahani (“Behbahani”), Carmen Chang (“Chang”), Anthony A. Florence, Jr. (“Florence”), Mohamad H. Makhzoumi (“Makhzoumi”), Scott D. Sandell (“Sandell”) and Paul Walker (“Walker”) (together, the “Managers”), Joshua Makower (“Makower”) and Peter W. Sonsini (“Sonsini”). The Managers are the managers of NEA 16 LLC.

The persons named in this Item 2 are referred to individually herein as a “Reporting Person” and collectively as the “Reporting Persons.”

The address of the principal business office of NEA 16, each Control Entity and Sandell is New Enterprise Associates, 1954 Greenspring Drive, Suite 600, Timonium, MD 21093. The address of the principal business office of Baskett, Behbahani, Chang, Makhzoumi, and Walker is New Enterprise Associates, 2855 Sand Hill Road, Menlo Park, California 94025. The address of the principal business office of Florence is New Enterprise Associates, 104 5^th Avenue, 19^th Floor, New York, NY 10011.

Item 3.  Source and Amount of Funds or Other Consideration

Not applicable.

Item 4. Purpose of Transaction.

Not applicable.

Item 5. Interest in Securities of the Issuer.

(a)

The amounts of Common Stock reported herein reflect a 1-for-10 reverse stock split effected by the Issuer on January 27, 2023 (the “Reverse Stock Split”). Prior to October 17, 2023 (the “Warrant Expiration Date”), NEA 16 held 375,000 warrants to purchase shares of Common Stock, exercisable immediately, at an exercise price of $50.00 per share with a five-year term (the “NEA 16 Warrants”). On the Warrant Expiration Date, the right of NEA 16 to exercise the NEA 16 Warrants expired by the terms of the applicable warrants and such right was not exercised by the NEA 16, in whole or in part, prior to such expiration (the “Warrant Expiration”).

Following the Reverse Stock Split and the Warrant Expiration, NEA 16 is the record owner of 1,071,428 shares of Common Stock (the “NEA 16 Shares”). As the general partner of NEA 16, NEA Partners 16 may be deemed to own beneficially the NEA 16 Shares. As the sole general partner of NEA Partners 16, NEA 16 LLC may be deemed to own beneficially the NEA 16 Shares. As members of NEA 16 LLC, each of the Managers may be deemed to own beneficially the NEA 16 Shares.

Each Reporting Person disclaims beneficial ownership of the NEA 16 Shares other than those shares which such person owns of record.

The percentage of outstanding Common Stock of the Issuer which may be deemed to be beneficially owned by each Reporting Person is set forth on Line 13 of such Reporting Person’s cover sheet. Such percentage was calculated based on 8,919,095 shares of Common Stock reported by the Issuer to be outstanding as of May 6, 2024 on the Issuer’s Form 10-Q filed with the Securities and Exchange Commission on May 15, 2024.

(b)

Regarding the number of shares as to which such person has:

(i)

sole power to vote or to direct the vote: See line 7 of cover sheets

(ii)

shared power to vote or to direct the vote: See line 8 of cover sheets

(iii)

sole power to dispose or to direct the disposition: See line 9 of cover sheets

(iv)

shared power to dispose or to direct the disposition: See line 10 of cover sheets

(c)

Except as set forth in Item 3 above, none of the Reporting Persons has effected any transaction in the Common Stock during the last 60 days.

(d)

No other person is known to have the right to receive or the power to direct the receipt of dividends from, or any proceeds from the sale of, Common Stock beneficially owned by any of the Reporting Persons.

(e)

Each of Makower and Sonsini has ceased to own beneficially five percent or more of the Issuer’s Common Stock as a result of ceasing to be a manager of NEA 16 LLC.

Item 6. Contracts, Arrangements, Undertakings or Relationships with Respect to Securities of the Issuer.

Not applicable.

Item 7. Material to be Filed as Exhibits.

Exhibit 1 – Agreement regarding filing of joint Schedule 13D.

Exhibit 2 – Power of Attorney regarding filings under the Securities Exchange Act of 1934, as amended.

Exhibit 3 – Power of Attorney on behalf of Joshua Makower regarding filings under the Securities Exchange Act of 1934, as amended.
