Curis, Inc. (NASDAQ: CRIS), a biotechnology company focused on the development of innovative therapeutics for the treatment of cancer, today announced that the U.S. Food and Drug Administration (FDA) has lifted the partial clinical hold on the TakeAim Lymphoma Phase 1/2 study of emavusertib after reviewing the comprehensive data package submitted by Curis.
| Curis working with clinical sites to resume enrollment Preliminary clinical data update expected in 2023 LEXINGTON, Mass., Aug. 18, 2022 /PRNewswire/ -- Curis, Inc. (NASDAQ: CRIS), a biotechnology company focused on the development of innovative therapeutics for the treatment of cancer, today announced that the U.S. Food and Drug Administration (FDA) has lifted the partial clinical hold on the TakeAim Lymphoma Phase 1/2 study of emavusertib after reviewing the comprehensive data package submitted by Curis.
“We are excited to announce that FDA has completed its review of the TakeAim Lymphoma study and has lifted the partial clinical hold. We are working with our clinical sites to quickly resume enrollment of new patients in this study in the third quarter,” said James Dentzer, President and Chief Executive Officer of Curis. Previously, Curis announced that the FDA had placed separate partial clinical holds on the TakeAim Leukemia and TakeAim Lymphoma studies on April 4 and April 11, 2022, respectively. The partial hold on the TakeAim Leukemia study was issued by the FDA Division of Hematologic Malignancies 1 (DHM1), which regulates clinical studies in leukemia. The partial hold on the TakeAim Lymphoma study, and the lifting of that hold, was issued by the FDA Division of Hematologic Malignancies 2 (DHM2), which regulates clinical studies in lymphoma. The partial clinical hold was lifted following agreement with the FDA on Curis’s strategy for rhabdomyolysis identification and management, as well as on the enrollment of at least nine additional patients at the 200 mg dose level of emavusertib in combination with ibrutinib. With the partial clinical hold lifted on the TakeAim Lymphoma study, the Company is updating its timeline for clinical data release to reflect the availability of updated preliminary data from this study in 2023. In addition, Curis is proactively discussing the clinical plans for emavusertib, including alignment on optimal dose and development path, with DHM2 for the TakeAim Lymphoma study. About Emavusertib (CA-4948) Emavusertib is an IRAK4 kinase inhibitor and IRAK4 plays an essential role in the toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) signaling pathways, which are frequently dysregulated in patients with cancer. TLRs and the IL-1R family signal through the adaptor protein MYD88, 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. Additionally, third parties have recently discovered that the long form of IRAK4 (IRAK4-L) is oncogenic and preferentially expressed in over half of patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). The overexpression of IRAK4-L is believed to be driven by a variety of factors, including specific spliceosome mutations such as SF3B1 and U2AF1. In addition to inhibiting IRAK4, emavusertib was also designed to inhibit FLT3, a known oncologic driver, which may provide additional benefit in patients with AML and MDS. About TakeAim Leukemia The TakeAim Leukemia study (NCT04278768) is a Phase 1/2 open-label dose escalation, dose expansion clinical trial investigating emavusertib as a monotherapy and in combination with azacitidine or venetoclax in patients with relapsed or refractory (R/R) AML or high risk MDS. After dose escalation in both monotherapy and combination therapy to determine the recommended Phase 2 dose (RP2D), we plan to expand five cohorts: monotherapy in AML patients with spliceosome and FLT3 mutations, monotherapy in patients with MDS and spliceosome mutations and combination therapy with azacitidine or venetoclax in patients without spliceosome or FLT3 mutations. The goals of the study are to determine several parameters including safety, maximum tolerated dose (MTD), RP2D and signals of activity. About TakeAim Lymphoma The TakeAim Lymphoma study (NCT03328078) is a Phase 1/2 open-label, dose escalation, dose expansion clinical trial investigating emavusertib as monotherapy and in combination with ibrutinib in patients with R/R hematologic malignancies, such as non-Hodgkin’s lymphoma and other B cell malignancies. After dose escalation in both monotherapy and combination therapy to determine the RP2D, we plan to expand four cohorts for combination treatment: marginal zone lymphoma, activated b-cell diffuse large b-cell lymphoma, primary CNS lymphoma, and patients developing adaptive resistance to ibrutinib monotherapy. The goals of the study are to determine several parameters including safety, MTD, RP2D and signals of activity. About Curis, Inc. Curis is a biotechnology company focused on the development of innovative therapeutics for the treatment of cancer. In 2015, Curis entered into a collaboration with Aurigene in the areas of immuno-oncology and precision oncology. As part of this collaboration, Curis has exclusive licenses to oral small molecule antagonists of immune checkpoints including the VISTA/PDL1 antagonist CA-170, and the TIM3/PDL1 antagonist CA-327, as well as the IRAK4 kinase inhibitor, emavusertib (CA-4948). Emavusertib is currently undergoing testing in the Phase 1/2 TakeAim Lymphoma trial, in patients with hematologic malignancies, such as non-Hodgkin’s lymphoma and other B cell malignancies, both as a monotherapy and in combination with BTK inhibitor ibrutinib, and the Phase 1/2 TakeAim Leukemia trial in patients with AML and MDS, for which it has received Orphan Drug Designation from the U.S. Food and Drug Administration. The FDA has placed a partial clinical hold on the TakeAim Leukemia trial during which no new patients will be enrolled, and current study participants benefiting from treatment may continue to be treated with emavusertib at doses of 300mg BID or lower. In addition, Curis is engaged in a collaboration with ImmuNext for development of CI-8993, a monoclonal anti-VISTA antibody, which is currently undergoing testing in a Phase 1 trial in patients with solid tumors. Curis is also party to a collaboration with Genentech, a member of the Roche Group, under which Genentech and Roche are commercializing Erivedge® for the treatment of advanced basal cell carcinoma.

Regulatory authorities may determine to delay or restrict Genentech’s and/or Roche’s ability to continue to develop or commercialize Erivedge in basal cell carcinoma (BCC). Erivedge may not demonstrate sufficient or any activity to merit its further development in disease indications other than BCC. Competing drugs may be developed that are superior to Erivedge. In connection with its agreement with Oberland Capital, Curis faces risks relating to the transfer and encumbrance of certain royalty and royalty-related payments on commercial sales of Erivedge, including the risk that, in the event of a default by Curis or its wholly-owned subsidiary, Curis could lose all retained rights to future royalty and royalty-related payments, Curis could be required to repurchase such future royalty and royalty-related payments at a price that is a multiple of the payments it has received, and its ability to enter into future arrangements may be inhibited, all of which could have a material adverse effect on its business, financial condition and stock price. Curis will require substantial additional capital to fund its business. If it is not able to obtain sufficient funding, it will be forced to delay, reduce in scope or eliminate some of its research and development programs, including related clinical trials and operating expenses, potentially delaying the time to market for, or preventing the marketing of, any of its product candidates, which could adversely affect its business prospects and its ability to continue operations, and would have a negative impact on its financial condition and its ability to pursue its business strategies. Curis faces substantial competition. Curis and its collaborators face the risk of potential adverse decisions made by the FDA and other regulatory authorities, investigational review boards, and publication review bodies. Curis may not obtain or maintain necessary patent protection and could become involved in expensive and time-consuming patent litigation and interference proceedings. Unstable market and economic conditions, natural disasters, public health crises, political crises and other events outside of Curis’s control could significantly disrupt its operations or the operations of third parties on which Curis depends and could adversely impact Curis’s operating results and its ability to raise capital. For example, the COVID-19 pandemic may result in closures of third-party facilities, impact enrollment in clinical trials or impact sales of Erivedge by Genentech and/or Roche. The extent to which the COVID-19 pandemic may impact Curis’s business or operating results is uncertain. Other important factors that may cause or contribute to actual results being materially different from those indicated by forward-looking statements include the factors set forth under the captions “Risk Factor Summary” and “Risk Factors” in our most recent Form 10-K and Form 10-Q, and the factors that are discussed in other filings that we periodically make with the Securities and Exchange Commission (“SEC”).
