Abstract Number:1660
Abstract Title: Preclinical investigation of orally bioavailable, potent KRASMulti inhibitor JAB-23425
Session: Novel Antitumor Agents 4
Time: April 17, 2023, 9:00 AM – 12:30 PM (ET)

KRASmulti inhibitor JAB-23425 targets multiple KRAS mutants in both RAS(ON) and RAS (OFF), with good selectivity over HRAS and NRAS. JAB-23425 has significant antitumor effect on cancer models with multiple KRAS mutations (such as G12D, G12V, and G13D) and amplification of wild type KRAS, and has no inhibitory effect on KRAS-independent cells. The KRASmulti inhibitor JAB-23425 is expected to solve the unmet clinical needs of patients with KRAS-mutated tumors. JAB-23425 is a leading compound of Jacobio’s KRASmulti inhibitor.

On March 14, 2023 Oryzon Genomics, S.A. (ISIN Code: ES0167733015, ORY), a clinical-stage biopharmaceutical company leveraging epigenetics to develop therapies in diseases with strong unmet medical need, reported the enrollment of the first patient in its Phase Ib trial of iadademstat in combination with gilteritinib in patients with relapsed/refractory acute myeloid leukemia (AML) harboring a FMS-like tyrosine kinase mutation (FLT3mut+), at the Massachusetts General Hospital in Boston, US (Press release, Oryzon, MAR 14, 2023, View Source;utm_medium=email&utm_campaign=NdP.07+15-03-2023+FPI+FRIDA+ENG562 [SID1234628705]).

FRIDA (NCT05546580) is an open-label, multicenter study of iadademstat plus gilteritinib for the treatment of patients with relapsed or refractory AML (R/R AML) with FLT3·mutations. The trial’s primary objectives are to evaluate the safety and tolerability of iadademstat in combination with gilteritinib in patients with FLT3mut+ R/R AML and to establish the Recommended Phase 2 Dose (RP2D) for this combination. Secondary objectives include evaluation of the treatment efficacy, measured as the rate of complete remission and complete remission with partial hematological recovery (CR/CRh), the duration of responses (DoR) and the assessment of measurable residual disease (MRD). The trial’s principal investigator is Amir Fathi, M.D., Associate Professor at Harvard Medical School and Director of the Leukemia Program at Massachusetts General Hospital. FRIDA will be conducted in 10-15 sites in the US. The study will enroll up to approximately 45 patients and if successful, the Company and FDA have agreed to hold a meeting to discuss the best plan to further develop this combination in this much in need AML population.

Dr. Carlos Buesa, President and CEO of Oryzon, said: "FRIDA’s initiation is a significant corporate milestone for Oryzon, marking a further expansion of our clinical pipeline as we seek to improve the treatment options for patients. Iadademstat has already shown strong efficacy data in AML. We hope this combination will open up new ways to treat these patients and make an important difference to their outlooks."

Oryzon’s Global Chief Medical Officer, Dr. Douglas Faller, said: "We are pleased to announce the first patient entering into the FRIDA trial. It is our hope that the combination of iadademstat and gilteritinib will safely provide deep and durable responses for patients whose leukemias are driven by FLT3 mutations."

FRIDA’s scientific rationale is based on iadademstat’s ability to inhibit the lysine specific demethylase 1 (LSD1), thereby triggering a powerful differentiating effect in hematologic cancers, as well as producing an anti-leukemic effect by targeting leukemic stem cells. Furthermore, the combination of iadademstat with

gilteritinib demonstrated a very strong synergy in FLT3·mut+ AML preclinical models. This together with the fact that iadademstat has been administered to more than 100 cancer patients (including AML patients) demonstrating a good safety profile, activity and excellent pharmacologic properties supports exploring its combination with FLT3 inhibitors in FLT3·mut+ AML, targeting between 30-40% of AML patients. In a recently finalized, Phase IIa study (ALICE trial) in elder/unfit AML patients, iadademstat demonstrated robust efficacy in combination with azacitidine, with 81% ORR in the evaluable patients, of which 64% were CR/CRi. Final data from the ALICE trial were presented as an oral communication at the recent 64th ASH (Free ASH Whitepaper) annual conference (see here for more details).

On March 14, 2023 Harpoon Therapeutics, Inc. (Nasdaq: HARP), a clinical-stage immuno-oncology company developing novel T cell engagers, reported that it will present data from five preclinical investigations in poster presentations at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting being held in Orlando, Fla., April 14-19, 2023 (Press release, Harpoon Therapeutics, MAR 14, 2023, View Source [SID1234628703]).

"The breadth of data from Harpoon’s five poster presentations at AACR (Free AACR Whitepaper) supports further investigation of additional tumor targets, combination approaches with TriTACs, as well as our next-generation technology platform with conditionally active T cell engager prodrugs, or ProTriTACs," said Julie Eastland, President and Chief Executive Officer of Harpoon Therapeutics. "Additionally, the preclinical data investigating the activity of TriTAC in an immunocompetent mouse model provide further validation of our ongoing and planned clinical efforts with HPN328 and HPN217, leveraging our proprietary TriTAC T cell engager platform. We look forward to further validation in the clinic as our research efforts continue."

About mRNA-4157/V940

Personalized cancer vaccines are designed to prime the immune system so that a patient can generate a tailored antitumor response specific to their tumor mutation signature. mRNA-4157/V940 is a novel investigational messenger ribonucleic acid (mRNA)-based personalized cancer vaccine consisting of a single synthetic mRNA coding for up to 34 neoantigens that is designed and produced based on the unique mutational signature of the patient’s tumor. Upon administration into the body, the algorithmically derived and mRNA-encoded neoantigen sequences are endogenously translated and undergo natural cellular antigen processing and presentation, a key step in adaptive immunity.

mRNA-4157/V940 is being developed in combination with KEYTRUDA. mRNA-4157/V940 is designed to stimulate an immune response by generating specific T cell responses based on the unique mutational signature of a patient’s tumor. KEYTRUDA is an immunotherapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells.

Moderna and Merck plan to initiate a Phase 3 study in adjuvant melanoma in 2023 and expect to rapidly expand to additional tumor types, including non-small cell lung cancer.

On March 14, 2023 Kura Oncology, Inc. (Nasdaq: KURA), a clinical-stage biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer, reported that two abstracts have been accepted for presentation at the upcoming American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting, to be held in Orlando from April 14-19, 2023 (Press release, Kura Oncology, MAR 14, 2023, View Source [SID1234628701]).

"We look forward to presenting preclinical data supporting the combination of farnesyl transferase inhibitors (FTIs) with KRASG12C inhibitors and tyrosine kinase inhibitors at this year’s AACR (Free AACR Whitepaper) Annual Meeting," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "These data add to the emerging body of evidence supporting the potential to use FTIs as combination agents to prevent or delay emergence of resistance to certain classes of targeted therapy. We recently announced FDA clearance of the Investigational New Drug application for our next-generation farnesyl transferase inhibitor, KO-2806, which was designed to improve upon potency, pharmacokinetic and physicochemical properties of earlier FTI drug candidates, and we look forward to initiating our FIT-001 Phase 1 trial with KO-2806 later this year."
