We believe with our recent clinical and regulatory 'wins,' we have foundationally set the stage for a transformational year ahead and the opportunity to drive significant value for all stakeholders. With that said, we continue to follow our CRc (complete response composite) preliminary data from our MB-106 Phase 1B/2 AML clinical trial. We are also pleased with the median durability continuing to climb – and is now in excess of 8 months," commented Walter Klemp, Chairman and Chief Executive Officer of Moleculin. Recent Highlights Appointed Daniel D. Von Hoff, M.D., F.A.C.P., FASCO, FAACR, leading expert in Pancreatic Cancer to its Scientific Advisory Board to Support Development of Annamycin; Hosted a Virtual Acute Myeloid Leukemia KOL event with internationally renowned Acute Myeloid Leukemia (AML) Key Opinion Leaders to discuss Annamycin, the use of anthracyclines, how Annamycin could significantly change the AML treatment landscape, and the Company's recently announced global Phase 3 pivotal trial for the treatment of AML patients who are refractory to or relapsed after induction therapy (R/R AML) (the "MIRACLE" trial); Presented positive in vivo efficacy data of Annamycin in orthotopic and experimental lung metastatic models of Sarcoma in a poster titled "Annamycin: Opening New Doors for Organotropic Targeting of Primary and Metastatic Lung Cancer," at the IASLC 2024 World Conference on Lung Cancer; Commenced enrollment and treatment of patients in the Investigator-initiated Phase 2 study evaluating WP1066 in combination with radiation therapy for the treatment of adults with glioblastoma; and Closed a $5.5 million financing upfront with up to an additional $11.0 million of potential aggregate gross proceeds upon the exercise in full of milestone-linked warrants. Clinical Development Update Annamycin is currently being evaluated in ongoing clinical trials for the treatment of relapsed or refractory acute myeloid leukemia (AML) and soft tissue sarcoma (STS) lung metastases. Annamycin currently has Fast Track Status and Orphan Drug Designation from the FDA for the treatment of relapsed or refractory acute myeloid leukemia, in addition to Orphan Drug Designation for the treatment of soft tissue sarcoma. Furthermore, Annamycin has Orphan Drug Designation for the treatment of relapsed or refractory acute myeloid leukemia from the European Medicines Agency (EMA). AML The Company recently announced the positive discussion and outcome of its End of Phase 1B/2 (EOP1B/2) meeting with the US Food and Drug Administration (FDA) supporting the advancement of Annamycin in combination with Cytarabine (also known as "Ara-C" and for which the combination of Annamycin and Ara-C is referred to as "AnnAraC") to a Phase 3 pivotal trial for the treatment of AML patients who are refractory to or relapsed after induction therapy (R/R AML). This Phase 3 "MIRACLE" trial (derived from Molecul in R/R AML AnnAraC Clinical Evaluation) will be a global trial, including sites in the US. The MIRACLE study, subject to appropriate future filings with and potential additional feedback from the FDA and their foreign equivalents, is expected to initially utilize an adaptive design whereby approximately the first 75 to 90 subjects will be randomized to receive high dose cytarabine (HiDAC) combined with either placebo, 190 mg/m2 of Annamycin, or 230 mg/m2 of Annamycin. At that point, the trial will be unblinded to select the optimum dose for Annamycin. For the second part of the trial, approximately 240 additional subjects will be randomized to receive either HiDAC plus placebo or HiDAC plus the optimum dose of Annamycin. The selection of the optimum dose will be based not only on the overall balance of safety, tolerability, pharmacokinetics and efficacy, consistent with the FDA's new Project Optimus initiative. Expected Milestones for Annamycin AML Development Program 4Q 2024 – Contracting with MIRACLE trial sites and IRB approval 1Q 2025 – First subject treated in MIRACLE trial 4Q 2025 – Recruitment and overall efficacy rate update (n=45) 2H 2026 – Interim efficacy and safety data (n=90) unblinded and Optimum Dose set for MIRACLE trial 2027 – Begin enrollment of 3rd line subjects in MIRACLE2 2027 – Enrollment ends in 2nd line subjects 2028 – Primary efficacy data for 2nd line subjects in MIRACLE 2028 2H – Begin submission of a Rolling New Drug Application (NDA) for the treatment of R/R AML for accelerated approval on primary endpoint of CR from MIRACLE STS Lung Metastases As previously announced, the Company completed enrollment in the Phase 2 portion of its U.S. Phase 1B/2 clinical trial evaluating Annamycin as monotherapy for the treatment of soft tissue sarcoma lung metastases. Subjects who had stable disease at the time of study discontinuation were followed for progression free response and overall survival. The study database is locked, and the clinical study report is being written and should be completed in early 2025 and will be released in detail at that time Expected Milestones for Annamycin STS Lung Mets Development Program 2025 – Final MB-107 data readout 2025 – Identify next phase of development / pivotal program Summary of Financial Results for the Third Quarter 2024 Research and development (R&D) expense was $4.9 million and $3.3 million for the three months ended September 30, 2024 and 2023, respectively. The increase over the prior year period is mainly related to costs incurred for clinical trials (clinical research organization and drug production) and sponsored research costs. General and administrative expense was $2.2 million and $2.6 million for the three months ended September 30, 2024 and 2023, respectively. The decrease of $0.4 million is mainly related to a decrease in regulatory and legal fees. As of September 30, 2024, the Company had cash and cash equivalents of $9.4 million and believes that the existing cash and cash equivalents as of September 30, 2024, will be sufficient to fund planned operations into the first quarter of 2025.

(Nasdaq: KURA), a clinical-stage biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer, today reported third quarter 2024 financial results and provided a corporate update. “We approach the end of 2024 in a strong position, with a series of important catalysts ahead,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “First, we look forward to sharing a robust dataset from more than 100 patients in our Phase 1a dose-escalation study of ziftomenib in combination with standards of care in acute myeloid leukemia (AML) at the upcoming American Society of Hematology (ASH) Annual Meeting, followed by topline results from our registration-directed trial of ziftomenib in relapsed/refractory (R/R) NPM1-mutant (NPM1-m) AML early next year. In the meantime, we continue to enroll rapidly across all our ziftomenib studies, further supporting the broad development of our menin inhibitor programs.” Recent Highlights Topline results from registration-directed trial of ziftomenib in early 2025 – In May 2024, Kura completed enrollment of 85 patients in the Phase 2 portion of KOMET-001, a registration-directed clinical trial of its menin inhibitor, ziftomenib, in patients with R/R NPM1-m AML. Ziftomenib is the first and only investigational therapy to be granted Breakthrough Therapy Designation (BTD) for the treatment of R/R NPM1-m AML, which accounts for approximately 30% of new AML cases annually and represents a disease of significant unmet need for which no approved targeted therapy exists. Results from the Phase 1 portion of KOMET-001 were recently published in the leading clinical oncology journal, The Lancet Oncology.Data from Phase 1a dose-escalation study of ziftomenib at ASH – Two abstracts reporting preliminary data from the Phase 1a dose-escalation study of ziftomenib in combination with standards of care in patients with NPM1-m and KMT2A-rearranged (KMT2A-r) AML have been accepted for presentation at the ASH Annual Meeting in December. As of the June 21, 2024 data cutoff, the abstracts continue to support a potential best-in-class safety and tolerability profile for ziftomenib, as well as robust and durable activity in combination with standards of care, including venetoclax plus azacitidine (ven/aza) as well as cytarabine plus daunorubicin (7+3). Kura expects to present a more mature dataset from more than 100 patients in the Phase 1a dose-escalation study in the presentations at ASH.Phase 1b expansion study of ziftomenib now enrolling in all cohorts – All four cohorts in the Phase 1a dose-escalation study have cleared the highest dose and advanced into the Phase 1b expansion study at 600 mg. The Phase 1b expansion study includes multiple combination cohorts, including ziftomenib plus ven/aza in newly diagnosed NPM1-m or KMT2A-r AML and ziftomenib plus 7+3 in newly diagnosed NPM1-m or KMT2A-r AML without qualification for high-risk disease. Each of the seven combination cohorts is expected to enroll at least 20 patients. A total of 45 patients have already enrolled in the study since the first dose-expansion cohort opened in August 2024. The Company anticipates sharing preliminary data from the Phase 1b expansion study at a medical meeting in 2025.Preclinical data support opportunity for ziftomenib in GIST – Last month, at the EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Kura reported preclinical data supporting the combination of ziftomenib and imatinib for the treatment of advanced gastrointestinal stromal tumors (GIST). The combination showed unexpectedly robust and durable antitumor activity in both imatinib-sensitive and imatinib-resistant GIST patient-derived xenograft models, and in all cases was significantly superior to imatinib monotherapy. The Company received FDA clearance of its Investigational New Drug application for ziftomenib for the treatment of advanced GIST in August and expects to initiate a proof-of-concept study in the first half of 2025 evaluating ziftomenib and imatinib in patients with advanced GIST who have failed imatinib.First patient dosed in study of KO-2806 and adagrasib in KRASG12C-mutated NSCLC – In August 2024, Kura began dosing patients in its study of KO-2806, a next-generation farnesyl transferase inhibitor (FTI), in combination with adagrasib in KRASG12C-mutated non-small cell lung cancer (NSCLC). The Company’s findings suggest that combining KO-2806 with adagrasib may drive tumor regressions and enhance both duration and depth of antitumor response in preclinical models of KRASG12C-mutated NSCLC. The study of KO-2806 and adagrasib is supported by a clinical collaboration and supply agreement with Mirati, now a Bristol Myers Squibb company.Preclinical data support potential for menin inhibitor in diabetes – In June 2024, Kura reported data showing that ziftomenib induces insulin production, improves insulin sensitivity and reduces insulin resistance in a preclinical in vivo model of type 2 diabetes. Ziftomenib demonstrated meaningful levels of glycemic control, including reduced fasting blood glucose levels and %HbA1C within 27 days, as well as consistent improvement in both insulin sensitivity and insulin production. The data were presented at the American Diabetes Association Scientific Sessions in Orlando. The Company expects to nominate a next generation menin inhibitor candidate targeting diabetes in the first half of 2025. Financial Results Research and development expenses for the third quarter of 2024 were $41.7 million, compared to $29.3 million for the third quarter of 2023.General and administrative expenses for the third quarter of 2024 were $18.2 million, compared to $13.1 million for the third quarter of 2023.Net loss for the third quarter of 2024 was $54.4 million, compared to a net loss of $38.6 million for the third quarter of 2023. This included non-cash share-based compensation expense of $8.3 million, compared to $7.1 million for the same period in 2023.As of September 30, 2024, Kura had cash, cash equivalents and short-term investments of $455.3 million, compared to $424.0 million as of December 31, 2023.Based on its operating plan, management expects that cash, cash equivalents and short-term investments will fund current operations into 2027. Forecasted Milestones Present updated data from the KOMET-007 trial of ziftomenib in combination with ven/aza and 7+3 at ASH in December 2024.Report topline results from the KOMET-001 registration-directed trial of ziftomenib in NPM1-mutant R/R AML in early 2025.Present preliminary data from the Phase 1b expansion portion of KOMET-007 at a medical meeting in 2025.Initiate proof-of-concept study evaluating ziftomenib and imatinib in patients with advanced GIST in the first half of 2025.Nominate a next generation menin inhibitor development candidate targeting diabetes in the first half of 2025.Identify the maximum tolerated dose for KO-2806 as a monotherapy in the second half of 2024.Initiate one or more expansion cohorts for the combination of KO-2806 and cabozantinib in renal cell carcinoma in the first half of 2025.Present data from the KURRENT-HN trial of tipifarnib in combination with alpelisib in PIK3CA-dependent head and neck squamous cell carcinoma (HNSCC) in the first half of 2025.
