Recent Developments
Previous report
In March 2024, we entered into an exclusive license agreement and a stock purchase agreement with Gilead. Under the license agreement, our wholly-owned subsidiary, Xilio Development, Inc., or Xilio Development, granted Gilead an exclusive global license to develop and commercialize XTX301, our tumor-activated IL-12 product candidate, and specified other molecules directed to IL-12. Xilio Development is responsible for conducting clinical development for XTX301 in the ongoing Phase 1 clinical trial through an initial planned Phase 2 dose expansion clinical trial. Following the delivery by Xilio Development of a specified clinical data package for XTX301 related to the Phase 1 clinical trial and planned Phase 2 clinical trial, Gilead can elect to transition responsibilities for the development and commercialization of XTX301 to Gilead, subject to the terms of the license agreement and payment by Gilead of a $75.0 million transition fee. Under the stock purchase agreement, Gilead agreed to purchase up to $25.0 million in common stock or, at Gilead’s election, prefunded warrants, including approximately $13.5 million in our common stock in connection with entering into the license agreement and approximately $11.5 million in up to three additional private placements through March 2025.
Previous report
We have received approximately $46.8 million to date under these agreements, including an upfront cash payment of $30.0 million received in April 2024 under the license agreement and $16.8 million in aggregate gross proceeds from the sale and issuance of common stock and prefunded warrants to Gilead under the stock purchase agreement. We are eligible to

March 2024 Private Placement
Previous report
In March 2024, we entered into a securities purchase agreement with certain existing accredited investors, including Bain Capital Life Sciences and Rock Springs Capital, and issued and sold an aggregate of 1,953,125 shares of our common stock at a price of $0.64 per share and prefunded warrants to purchase up to an aggregate of 15,627,441 shares of our common stock at a purchase price of $0.6399 per prefunded warrant share, through a private investment in public equity financing. The prefunded warrants have an exercise price of $0.0001 per share of common stock, are immediately exercisable and remain exercisable until exercised in full. The private placement closed in April 2024, and we received aggregate gross proceeds of approximately $11.3 million, before deducting placement agent fees and expenses payable by us. We expect to use the proceeds from the private placement to fund working capital and other general corporate purposes.

Reworded paragraphs (21)
Previous wording
We are a clinical-stage biotechnology company discovering and developing tumor-activated immuno-oncology, or I-O, therapies with the goal of significantly improving outcomes for people living with cancer without the systemic side effects of current I-O treatments. We are leveraging our proprietary platform to build a pipeline of novel, tumor-activated I-O molecules that are designed to optimize the therapeutic index by localizing anti-tumor activity within the tumor microenvironment, including tumor-activated cytokines and antibodies (including bispecifics) and immune cell engagers (including tumor-activated cell engagers and tumor-activated effector-enhanced cell engagers). Current I-O therapies have curative potential for patients with cancer; however, their potential is significantly curtailed by systemic toxicity that results from activity of the therapeutic molecule outside the tumor microenvironment. Our molecules are engineered to localize activity within the tumor microenvironment with minimal systemic effects, resulting in the potential to achieve enhanced anti-tumor activity and increasing the population of patients who may be eligible to receive our medicines. Our most advanced tumor-activated, clinical-stage product candidates are: XTX101, an Fc-enhanced, anti-CTLA-4 monoclonal antibody, or mAb; XTX301, an interleukin 12, or IL-12, therapy; and XTX202, an interleukin 2, or IL-2, therapy. To date, we have presented clinical data across these programs showing initial clinical validation for each of these molecules and our tumor-activated approach. In addition to our clinical-stage product candidates, we are continuing to leverage our differentiated research platform and expertise in developing tumor-activated I-O therapies to advance preclinical development for tumor-activated bispecific molecules and immune cell engager molecules (including tumor-activated cell engagers and tumor-activated effector-enhanced cell engagers). As a result of our strategic portfolio reprioritization announced in March 2024, we are focusing on rapidly advancing clinical development for XTX301 and XTX101 and advancing differentiated bispecific and cell-engager molecules in preclinical development, and we plan to explore strategic opportunities to continue to develop XTX202 in combination with other agents while discontinuing further investment in XTX202 as a monotherapy.

To date, we have financed our operations primarily from proceeds raised through private placements of preferred units and convertible preferred stock, a debt financing, our initial public offering, or IPO, of common stock in October 2021, private placements of our common stock and prefunded warrants, and an upfront payment under our exclusive license agreement with Gilead Sciences, Inc., or Gilead. We have not generated any revenue from product sales and do not expect to generate any revenue from product sales for at least the next several years, if at all. All of our programs are in early clinical or preclinical development. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our product candidates, if approved. Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve profitability. Even if we are able to generate revenue from product sales, we may not become profitable.

As a result, we will need substantial additional capital to support our continuing operations and pursue our strategy. As of March 31, 2024, we had cash and cash equivalents of $34.0 million. Based on our current operating plans, we anticipate that our existing cash and cash equivalents as of March 31, 2024, together with the $30.0 million upfront payment received in April 2024 under our license agreement with Gilead and approximately $14.6 million in aggregate gross proceeds received in April 2024 from private placements with certain existing investors and Gilead, will be sufficient to enable us to fund our operating expenses and capital expenditure requirements into the second quarter of 2025. Since these amounts may not be sufficient to fund our operations for at least twelve months from the date of issuance of the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, there is substantial doubt about our ability to continue as a going concern. For more information, refer to “—Liquidity and Capital Resources—Capital Requirements and Going Concern” below and Note 1 to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

We expense research and development costs as incurred. We recognize external development costs based on an evaluation of the progress to completion of specific deliverables using information provided to us by our vendors. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our condensed consolidated balance sheets as prepaid expenses or accrued research and development expenses. We record cost-sharing payments under our clinical trial collaboration with F. Hoffmann-La Roche Ltd., or the Roche clinical collaboration, as a reduction of research and development costs upon the achievement of each study development event specified in the clinical supply agreement. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are capitalized as assets, even when there is no alternative future use for the research and development. The capitalized amounts are expensed as the related goods are delivered or the services are performed.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect that our research and development expenses will remain approximately the same or will continue to increase for the foreseeable future as we advance our programs and our current or future product candidates into and through the development phase. We expect our discovery research efforts and our related personnel costs to remain consistent with historical levels. In addition, as we progress our most advanced product candidates in clinical development, we may incur additional expenses related to milestone and royalty payments payable to third parties with whom we have entered into, or may enter into license, acquisition, option or other agreements to acquire the rights to future products and product candidates. In the event we are unable to raise sufficient additional capital in the near term to fund our operations, we will be required to adopt cost reduction strategies that seek to maintain our ability to continue the development of our most advanced product candidates in clinical development while otherwise reducing our overall research and development expenses.

In November 2022, we filed a universal shelf registration statement on Form S-3 with the SEC, or Form S-3, to register for sale up to $250,000,000 of our common stock, preferred stock, debt securities, units and warrants, which we may issue and sell from time to time in one or more offerings, which became effective on November 18, 2022 (333-268264). In November 2022, we also entered into a sales agreement, or the Sales Agreement, with Cowen and Company LLC, under which we may issue and sell shares of our common stock, from time to time, having an aggregate offering price of up to $75.0 million, subject to the terms and conditions of the Sales Agreement. Through the filing date of this Quarterly Report on Form 10-Q, we have not issued or sold any shares of our common stock pursuant to the Sales Agreement. Issuances or sales of common stock pursuant to the Sales Agreement, if any, would be made under the Form S-3 and the corresponding prospectus related to the issuance and sale of shares of common stock pursuant to the Sales Agreement. The extent to which we use the Sales Agreement as a source of funding will depend on a number of factors, including the prevailing market price of our common stock, general market conditions, the extent to which we are able to secure funds from other sources, and whether we are then subject to limitations on our ability to use Form S-3 to sell more than one-third of the aggregate market value of our public float in the trailing 12-month period. Accordingly, we may not be able to sell shares under the Sales Agreement at prices or in amounts that we deem acceptable, and there can be no assurance that we will sell any shares of common stock pursuant to the Sales Agreement.

In November 2019, Xilio Development entered into a loan and security agreement with PacWest, as amended and restated in May 2023, with us as a guarantor. In November 2019, we borrowed $10.0 million under a term loan pursuant to the loan agreement. Borrowings under the loan agreement were collateralized by substantially all of the assets of Xilio Development, excluding intellectual property. Interest on amounts outstanding accrued at a variable annual rate equal to the greater of (i) the prime rate plus 0.25% or (ii) 4.75%. We made interest-only payments on the outstanding balance through December 31, 2022. We commenced making equal monthly payments of principal plus interest in January 2023. In the first quarter of 2024, we repaid all amounts outstanding under the loan agreement, and PacWest released all security interests in our and our subsidiaries’ assets.
Previous wording
As of March 31, 2024, we had cash and cash equivalents of $34.0 million. Based on our current operating plans, we anticipate that our existing cash and cash equivalents as of March 31, 2024, together with the $30.0 million upfront payment received in April 2024 under our license agreement with Gilead and approximately $14.6 million in aggregate gross proceeds received in April 2024 from private placements with certain existing investors and Gilead, will be sufficient to enable us to fund our operating expenses and capital expenditure requirements into the second quarter of 2025. However, we have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we anticipate. In addition, since these amounts may not be sufficient to fund our operations for at least twelve months from the date of issuance of the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, there is substantial doubt about our ability to continue as a going concern. Our management has developed plans to fund our operations, which primarily consist of raising additional capital through one or more of the following: additional equity or debt financings; additional collaborations partnerships or licensing transactions; or other sources. However, there can be no assurance that we will be able to complete any such transaction on acceptable terms or otherwise, and we may be unable to obtain sufficient additional capital. If we are not able to secure sufficient additional capital in the near term, we may in the future need to implement additional cost reduction strategies, which could include delaying, limiting, further reducing or eliminating both internal and external costs related to our operations and research and development programs. The accompanying condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business for the foreseeable future. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

Previous wording
Adequate additional capital may not be available to us on acceptable terms, or at all. Market volatility resulting from adverse changes in domestic and international fiscal, monetary and other policies and political relations, regional or global conflicts, uncertainty around global economic conditions, instability in the financial markets, current or future pandemics, or other factors could also adversely impact our ability to access capital as and when needed. To the extent that we raise additional capital through the sale of equity or securities convertible into or exchangeable for equity, the ownership interest of our existing stockholders may be diluted, and the terms of such securities may include liquidation or other preferences that adversely affect the rights of our existing stockholders. Additional debt and preferred equity, if available, may also involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends and may require that we issue warrants, which could potentially dilute the ownership interest of our existing stockholders.

Other income, net, was relatively unchanged and was $0.8 million for both the three months ended June 30, 2024 and 2023. This was primarily due to an offsetting decrease in interest income earned on our cash and cash equivalents due to a lower average cash balance and lower interest expense on our note payable as a result of the repayment of the remaining principal under our loan agreement with PacWest in March 2024.
