Immuneering Reports Compelling Preclinical Data on IMM-1-104 in NRAS Mutant Melanoma Model And Will Host Key External Expert Investor Event
Immuneering Corporation (Nasdaq: IMRX) has revealed promising preclinical data for its lead product candidate, IMM-1-104, indicating its potential to inhibit tumor growth in NRAS mutant melanoma models. This data, which compares IMM-1-104 to binimetinib, suggests superior efficacy, achieving tumor growth inhibition rates between 74.9% and 99.9%. The company plans to submit an Investigational New Drug application to the FDA in Q3 2022 and aims to commence human clinical trials by Q4 2022. The findings underscore IMM-1-104’s potential as a therapeutic alternative in treating RAS mutant tumors.
- IMM-1-104 demonstrated significantly higher tumor growth inhibition (74.9% to 99.9%) compared to binimetinib (20.6% to 35.6%).
- The upcoming FDA IND application submission for IMM-1-104 is planned for Q3 2022.
- Plans to commence human clinical trials for IMM-1-104 in Q4 2022.
- Binimetinib's previous clinical trial (NEMO study) showed no improvement in overall survival compared to control.
Preclinical Data Suggest IMM-1-104 May Offer Unique Therapeutic Advantage Compared with Binimetinib in NRAS Mutant Tumors
Data to be discussed in Key External Expert event on January 6 2022, 5PM Eastern Time
CAMBRIDGE, Mass., Jan. 06, 2022 (GLOBE NEWSWIRE) -- Immuneering Corporation (Nasdaq: IMRX), a biopharmaceutical company advancing a robust pipeline of oncology and neuroscience product candidates that are designed to uniquely disrupt cellular signaling dynamics, today announced preclinical data highlighting the potential of its lead product candidate, IMM-1-104, to inhibit tumor growth in NRAS mutant melanoma models. The data were submitted as a poster presentation at the recently postponed American Association for Cancer Research (AACR) Special Conference: Targeting RAS (originally scheduled for January 7-10, 2022). Given that abstracts are not being published at this time due to postponement of the event, Immuneering is making available the data in a presentation titled “Head-to-Head Comparison of the Dual-MEK Inhibitor IMM-1-104 Versus Binimetinib in NRAS Mutant Melanoma Models,” by Peter King, PhD, Vice President and Head of Discovery at Immuneering on its website (www.immuneering.com/publications/).
IMM-1-104 is a novel, allosteric dual-MEK inhibitor that is designed to disrupt phosphorylation of both MEK and its downstream target ERK and has a short plasma drug half-life, with the aim of enabling deep cyclic inhibition with a near-zero drug trough. The Company anticipates submission of an Investigational New Drug application (IND) for IMM-1-104 to the U.S. Food and Drug Administration (FDA) in the third quarter of this year.
“These compelling data add to the growing body of preclinical evidence in support of IMM-1-104’s potential to inhibit tumors driven by the MAPK pathway including KRAS and NRAS mutant tumors. This is especially important because existing drugs targeting this pathway often are limited by toxicity or are narrowly focused on subpopulations with specific mutations,” said Ben Zeskind, Ph.D., Co-Founder, President and Chief Executive Officer of Immuneering. “We look forward to evaluating IMM-1-104 in human clinical trials, with plans to enroll the first patient in the fourth quarter of this year. The preclinical data we are sharing today further support IMM-1-104’s differentiation from previously developed therapies, and showcase the potential of its deep cyclic inhibition mechanism to achieve our goal of selectively impacting RAS mutant tumors with greater durability and reduced overall toxicity.”
In this preclinical study, Immuneering modeled binimetinib versus IMM-1-104 in SK-MEL-2 in vivo. SK-MEL-2 is a melanoma tumor cell line that displays a similar molecular profile to approximately half of the patients who participated in the Phase 3 NEMO study, displaying an NRAS-Q61R mutation. The NEMO study results showed binimetinib did not improve overall survival compared with dacarbazine (11.0 vs. 10.1 months, respectively) in NRAS mutant melanoma patients and, in fact, showed a

Immuneering researchers tested IMM-1-104 head-to-head compared with binimetinib across a series of preclinical experiments to better understand differential in vivo and in vitro activity of each compound. Cell-based 2D and 3D in vitro biochemical and pharmacologic assays were performed across nine melanoma models. The SK-MEL-2 melanoma xenograft mouse model was used to evaluate single agent activity of IMM-1-104 (50, 100, 125, 150 mg/kg BID p.o.) compared with binimetinib (3, 10, 30 mg/kg BID p.o.) for 21 days treatment after tumors had reached 150 to 200 mm2.
Head-to-head comparison in vivo showed binimetinib had little effect on curtailing growth of SK-MEL-2 melanoma tumors (Tumor Growth Inhibition (TGI) range =
Dr. King concluded, “Collectively, our data suggest that binimetinib may not effectively control MAPK pathway reactivation in RAS mutant tumors whereas the deep, cyclic dual-MEK approach of IMM-1-104 may offer a unique therapeutic advantage over first generation MEK inhibitors in this indication.”
Immuneering will be hosting a Key External Expert Event, which will review the data. Event details are below:
