ITEM 1. SECURITY AND ISSUER.

This Schedule 13D pertains to the common stock, par value NIS 2.40 (“Common Stock”), of Check-Cap LTD, an Israeli corporation (“Issuer”). The Issuer’s principal executive office is located at Check-Cap Building 29 Abba Hushi Avenue, P.O. Box 1271, Isfiya, 30090, Mount Carmel, Israel.

ITEM 2. IDENTITY AND BACKGROUND.

(a) This statement on Schedule 13D is filed by Symetryx Corporation (“Symetryx”).

(b) The principal business and office address of Symetryx is:

2828 Bathurst Street Suite 400

Toronto, Canada M6B3A7.

(c) Symetryx is a Family Office that invests its funds in business entities. The principal business address of Symetryx is as set forth in (b) above.

(d) During the last five years, Symetryx has not been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) During the last five years, Symetryx has not been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding 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.

(f) Symetryx is incorporated in Ontario, Canada.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

Symetryx used USD$1,043,073 of working capital to purchase shares of the Common Stock of Issuer.

ITEM 4. PURPOSE OF TRANSACTION.

(a) Symetryx does not intend to sell shares of Issuer Common Stock or purchase additional shares of Issuer Common Stock.

(b) On July 18, 2023, Symetryx issued a press release stating, among other information, that Symetryx announced a non-binding proposal to acquire shares of Issuer Common Stock from Issuer’s shareholders at a price of $4.35 per share in cash, contingent upon satisfying specified conditions (“Non-binding Proposal”). These conditions included, among others, that the Issuer’s Board of Directors immediately engage with Symetryx, and completion of a due diligence review of Issuer. Symetryx also urged that the Board of Directors enter into a nondisclosure agreement with Symetryx.

On July 25, 2023, Symetryx issued a press release stating, among other information, it increased the cash purchase price per share of Issuer Common Stock from $4.35 per share to $4.60 per share in cash. Symetryx stated that Issuer’s Board of Directors had not yet responded to Symetryx request to communicate with them and allow Symetryx to begin due diligence as outlined in Symetryx July 18, 2023, press release. Symetryx also stated that, if Issuer’s Board of Directors does not engage in communications with Symetryx regarding its non-binding proposal to acquire shares, Symetryx may consider making a tender offer directly to Issuer’s shareholders in accordance with U.S. federal securities law and regulations.

On August 10, 2023, the Chairman of Issuer’s Board of Directors sent an email to Symetryx proposing a conversation with him and another member of the Board. Symetryx did not reply to that email.

As of September 26, 2023, Symetryx withdraws and terminates its Non-binding Proposal.

Symetryx is aware (based on the Form 6-K filed by Issuer with the SEC) that, on August 16, 2023, Issuer entered into a business combination agreement (“BCA”) with Keystone Dental Holdings, Inc., a Delaware corporation, Capstone Dental PubCo, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of Keystone, Capstone Merger Sub Ltd., an Israeli company and a direct, wholly owned subsidiary of PubCo, and Capstone Merger Sub Corp., a Delaware corporation and a direct, wholly owned subsidiary of PubCo (collectively “Capstone Dental”). Closing of the transactions contemplated by the BCA requires, among other items, approval of Issuer’s shareholders at a Special Meeting of Shareholders that Issuer has publicly reported it anticipates holding in the fourth quarter of 2023.

3

On September 21, 2023, Symetryx issued a press release stating, among other information, that Symetryx will strongly oppose the transactions contemplated by the BCA as it believes that the merger target does not represent the maximum value that shareholders could receive on completion of a transaction

Symetryx intends to vote its shares of Issuer Common Stock against the transactions contemplated by the BCA, and to encourage other holders of Issuer Common Stock to vote their shares against these contemplated transactions.

Symetryx intends to propose to Issuer a different merger candidate. As of the filing date of this Schedule 13D, Symetryx does not yet have a specific merger candidate that it intends to propose to Issuer.

(c) Not applicable.

(d) Based solely upon the Form 20-F Issuer filed with the SEC on March 31, 2023, Symetryx believes that Issuer’s Board of Directors is currently comprised of five members: Steven Hanley, Clara Ezed, Mary Jo Gorman, XiangQian (XQ) Lin, and Yuval Yanai (each a “Current Director”). Under the Israeli Companies Law, a holder of not less than 5% of the shares of outstanding stock of an Israeli corporation is entitled to demand that corporation’s board of directors call a special meeting of its shareholders. Symetryx sent Issuer’s Board of Directors a letter, dated September 29, 2023 (“Demand Letter”), demanding that the Board calls a special meeting of Issuer’s shareholders to consider and vote upon removal of each of the Current Directors as directors and electing/ appointing the certain experienced and independent director nominees, namely Avital Shafran, Jordan Lipton, Idan Ben Shitrit, William Vozzolo and Liliane Malczewsky in their places.

The Demand Letter is filed with this Schedule 13D as Exhibit 99.3.

On September 29, 2023, Symetryx requested the board of directors of Check-Cap Ltd. to call an extraordinary general meeting of its shareholders no later than October 20, 2023. Since the Check-Cap declined our request to convene, and has not timely called nor convened the meeting as required by applicable law, Symetryx has taken it upon itself to convene a shareholders meeting. The full notice of meeting and proxy are attached as Exhibit 99.4.

On November 12, 2023, Check-Cap and Symetryx reached terms of settlement under which Symetryx will cancel its special shareholders meeting and Check-Cap has agreed that it will convert its special shareholder meeting to an annual general meeting of shareholders to be held on December 18, 2023.

The notice and proxy materials will be sent to shareholders of record by Check-Cap this week, which will include, the election of five directors to the Check-Cap Board out of ten director nominees (five being proposed by Symetryx and five being proposed by Check-Cap) and other proposals in connection with an annual shareholders meeting including the proposed Check-Cap- Keystone Transaction.

The parties have agreed that once the Check-Cap annual shareholder meeting has been convened, the pending legal proceedings filed by Symetryx will be withdrawn.

Symetryx is pleased with this outcome as it will avoid unnecessary delays, further court proceedings and the preservation of funds (for the benefit of the shareholders) that would otherwise have been spent by Check-Cap on legal and court fees.

Symetryx intends to vote AGAINST the Keystone transaction (the “Transaction”) and vote FOR its five-nominees to the Check-Cap Board of Directors which include: Idan Ben Shitrit, Avital Shafran, Jordan Lipton, William Vozzolo and Lilian Malczewski. Symetryx also urges its fellow shareholders to likewise vote AGAINST the Transaction and to vote FOR all five of Symetryx’s highly qualified and independent director nominees.

On November 24, 2023 Check-Cap filed its proxy materials on EDGAR along with the position statement of Symetryx with respect to its view on how fellow shareholders should vote on the Keystone Transaction. Symetryx strongly opposes the Keystone Transaction for the reasons disclosed in its position statement – a copy of which is included as Exhibit 99.5.
