Previous wording

We are a biotechnology company focused on the development of emavusertib (CA-4948), an orally available, small molecule inhibitor of Interleukin-1 receptor associated kinase, or IRAK4. IRAK4 plays an essential role in the toll-like receptor, or TLR, and interleukin-1 receptor, or IL-1R, signaling pathways, which are frequently dysregulated in patients with cancer. TLRs and the IL-1R family signal through the adaptor protein Myeloid Differentiation Primary Response Protein 88, which results in the assembly and activation of IRAK4, initiating a signaling cascade that induces cytokine and survival factor expression mediated by the NF-κB protein complex. Many B-cell leukemias and lymphomas are associated with constitutive activation of the NF-κB protein complex which contributes to these cancer’s proliferation and survival. The B-cell receptor, or BCR, and TLR pathways drive NF-κB activation. Preclinical studies demonstrated that targeting both the BCR and TLR pathways was more synergistic than targeting either pathway alone. Similarly, preclinical studies targeting IRAKi in combination with FMS‐like tyrosine kinase 3, or FLT3, have demonstrated the ability to overcome the adaptive resistance incurred when targeting FLT3 alone. In acute myeloid leukemia, or AML, patient derived xenografts, emavusertib has shown monotherapy anti-tumor activity as well as synergy with both azacitidine and venetoclax. In the clinic, emavusertib has shown anti-tumor activity across a broad range of hematologic malignancies including monotherapy activity in AML, particularly those with a FLT3 mutation. In non-Hodgkin's lymphoma patients, particularly in primary central nervous system lymphoma, or PCNSL, emavusertib has shown anti-tumor activity in combination with a Bruton Tyrosine Kinase, or BTK, inhibitor.

In addition to the TakeAim Leukemia Phase 1/2 study, we are testing emavusertib in combination with ibrutinib, a BTK inhibitor, in a Phase 1/2 open-label, single arm expansion trial in patients with R/R PCNSL, also known as the TakeAim Lymphoma Phase 1/2 study. In June 2022 and December 2023, we provided preliminary clinical data for patients with various hematological malignancies in the combination portion of the ongoing TakeAim Lymphoma Phase 1/2 study. In December 2023, we provided clinical and safety data of emavusertib in combination with ibrutinib in several non-Hodgkin's lymphoma subtypes including PCNSL patients. In September 2024, we provided additional clinical data of emavusertib in combination with ibrutinib in R/R PCNSL. We expect additional data from this study in December 2024 as well as in the first quarter of 2025.

Current wording

Emavusertib is currently undergoing testing in combination with ibrutinib, a BTK inhibitor, in a Phase 1/2 open-label, single arm expansion trial in patients with R/R PCNSL (NCT03328078), also known as the TakeAim Lymphoma Phase 1/2 study.

We have initiated a Phase 1 clinical study of emavusertib as an add-on agent to the combination of azacitidine and venetoclax to assess the safety of the triplet regimen in AML, which we refer to as the AML Triplet study. The AML Triplet study is currently being conducted in Spain, Germany, and Italy. We expect initial safety data from this study in the first quarter of 2025.

Current wording

We have initiated a Phase 1 clinical study of emavusertib as an add-on agent to the combination of venetoclax and azacitidine in AML (2023-505828-58), which we refer to as the AML Triplet study. The AML Triplet study is currently being conducted in Spain, Germany, and Italy. The study is assessing the safety and tolerability of different dosing regimens of emavusertib in the triple combination in patients who achieved a complete remission on venetoclax and azacitidine, while remaining positive for minimal residual disease. To date, the trial has enrolled the first dosing cohort of emavusertib in combination with venetoclax and azacitidine. All patients in this cohort tolerated the triple regimen well, with no unexpected adverse events. As a result, the external Clinical Safety Review Committee recommended to escalate to the next dosing cohort, and enrollment for this cohort is currently ongoing.

Since our inception, we have funded our operations primarily through private and public placements of our equity securities, license fees, contingent cash payments, royalties and research and development funding from our corporate collaborators, and the monetization of certain royalty rights. We have never been profitable on an annual basis and had an accumulated deficit of $1.2 billion as of September 30, 2024. For the nine months ended September 30, 2024, we incurred a net loss of $33.8 million and used $30.3 million of cash in operations.

For the three months ended March 31, 2025, we incurred a net loss of $10.6 million and used $7.3 million of cash in operations.

Previous wording

We expect to continue to generate operating losses in the foreseeable future. Based upon our current operating plan, we believe that our $20.9 million of existing cash and cash equivalents at September 30, 2024 and the net proceeds of approximately $10.8 million from the October 2024 Offerings discussed below should enable us to fund our operating expenses and capital expenditure requirements into mid-2025. We have based this assessment on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. Our current cash and cash equivalents are not expected to fund our operations beyond 12 months from the date of filing this Quarterly Report on Form 10-Q. See “Liquidity and Capital Resources—Funding Requirements” below and Note 1, Nature of Business, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for a further discussion of our liquidity and the conditions and events that raise substantial doubt regarding our ability to continue as a going concern.

Previous wording

We will need to generate significant revenues to achieve profitability, and do not expect to achieve profitability in the foreseeable future, if at all. We will require additional funding to fund the development of emavusertib through regulatory approval and commercialization, and to support our continued operations. We will need to seek additional funding through a number of potential avenues, including private or public equity financings, collaborations, or other strategic transactions. If sufficient funds are not available, we will have to delay, reduce the scope of, or eliminate our research and development program for emavusertib, including related clinical trials and operating expenses, potentially delaying the time to market for or preventing the marketing of emavusertib, which could adversely affect our business prospects and our ability to continue our operations, and would have a negative impact on our financial condition and ability to pursue our business strategies. In addition, we may seek to engage in one or more strategic alternatives, such as a strategic partnership with one or more parties, the licensing, sale or divestiture of some of our assets or proprietary technologies or the sale of our company, but there can be no assurance that we would be able to enter into such a transaction or transactions on a timely basis or on terms favorable to us, or at all.

If we are unable to obtain sufficient capital, we would be unable to fund our operations and may be required to evaluate alternatives, which could include dissolving and liquidating our assets or seeking protection under the bankruptcy laws, and a determination to file for bankruptcy could occur at a time that is earlier than when we would otherwise exhaust our cash resources. If we decide to dissolve and liquidate our assets or to seek protection under the bankruptcy laws, it is unclear to what extent we would be able to pay our obligations, and, accordingly, it is further unclear whether and to what extent any resources would be available for distributions to stockholders.

Any changes in the outcome of any of these variables with respect to the development of emavusertib could mean a significant change in the costs and timing associated with the development of emavusertib. For example, if the U.S. Food and Drug Administration or another regulatory authority requests additional or unanticipated data for our clinical trials or requires us to conduct clinical trials or other testing beyond those that we currently expect, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time to complete clinical development of that drug candidate. We may never obtain regulatory approval for emavusertib. If we do obtain regulatory approval for our drug candidate, drug commercialization will take several years and the associated costs will be significant.

Previous wording

We have incurred significant losses since our inception. As of September 30, 2024, we had an accumulated deficit of approximately $1.2 billion. We will require substantial funds to continue our research and development program and to fulfill our planned operating goals. Our planned operating and capital requirements currently include the support of our current and future research and development activities for emavusertib as well as development candidates we have and continue to license under our collaboration with Aurigene. We will require substantial additional capital to fund the further development of emavusertib and our general and administrative costs. Moreover, our agreements with collaborators impose significant potential financial obligations on us.

Previous wording

Business, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for a further discussion of our liquidity and the conditions and events that raise substantial doubt regarding our ability to continue as a going concern. Our resources are focused on emavusertib. If we are unable to obtain sufficient funding, we will be forced to delay, reduce in scope or eliminate our research and development program for emavusertib, including related clinical trials and operating expenses, potentially delaying the time to market for, or preventing the marketing of, emavusertib, which could adversely affect our business prospects and our ability to continue operations, and would have a negative impact on our financial condition and our ability to pursue our business strategies. Our ability to raise additional funds will depend on financial, economic and market conditions, many of which are outside of our control, and we may be unable to raise financing when needed, or on terms favorable to us, or at all. In addition, we may seek to engage in one or more strategic alternatives, such as a strategic partnership with one or more parties, the licensing, sale or divestiture of some of our assets or proprietary technologies or the sale of our company, but there can be no assurance that we would be able to enter into such a transaction or transactions on a timely basis or on terms favorable to us, or at all. Our failure to raise capital through a financing or strategic alternative as and when needed would have a negative impact on our financial condition and our ability to pursue our business strategy. If we are unable to obtain sufficient capital, we would be unable to fund our operations and may be required to evaluate alternatives, which could include dissolving and liquidating our assets or seeking protection under the bankruptcy laws, and a determination to file for bankruptcy could occur at a time that is earlier than when we would otherwise exhaust our cash resources. If we decide to dissolve and liquidate our assets or to seek protection under the bankruptcy laws, it is unclear to what extent we would be able to pay our obligations, and, accordingly, it is further unclear whether and to what extent any resources would be available for distributions to stockholders.

Current wording

Based upon our current operating plan, we believe that our existing cash and cash equivalents of $20.3 million as of March 31, 2025, should enable us to fund our existing operations into the fourth quarter of 2025. We have based this assessment on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. Our current cash and cash equivalents are not expected to fund our operations beyond 12 months from the date of filing this Quarterly Report on Form 10-Q. See Note 1, Nature of Business, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for a further discussion of our liquidity and the conditions and events that raise substantial doubt regarding our ability to continue as a going concern.
