Monte Rosa's Experimental Heart Disease Drug Shows Dramatic Results in Early Trial

Monte Rosa Therapeutics reported encouraging Phase 1 data for MRT-8102, showing the drug safely reduced inflammation markers linked to cardiovascular disease by up to 85% in patients with elevated risk factors.

Monte Rosa Therapeutics Inc. (GLUE) dropped some genuinely interesting data Wednesday that might make cardiologists sit up a little straighter. The clinical-stage biotech released interim results from its ongoing Phase 1 study of MRT-8102, an experimental drug targeting inflammatory pathways that contribute to heart disease. And the numbers look pretty compelling.

The trial is evaluating MRT-8102's safety, tolerability, and how it affects inflammation driven by the NLRP3 inflammasome, along with inflammatory proteins IL-1 and IL-6. These aren't just random biological markers—they're key players in the inflammatory processes that can lead to cardiovascular problems.

What the Study Looked At

The Phase 1 study has multiple parts. The single ascending dose cohort enrolled 48 healthy volunteers, while the multiple ascending dose portion enrolled 40 subjects. But the really interesting data comes from Part 3, which specifically targeted 24 subjects with elevated cardiovascular disease risk due to obesity and elevated C-reactive protein levels. These patients completed four weeks of dosing.

Part 3 was designed to evaluate safety and tolerability while tracking changes in CRP levels, pharmacokinetics, and other inflammatory markers—basically, does it work and is it safe in people who actually need it?

The Results That Got Everyone's Attention

MRT-8102 demonstrated rapid, deep, and sustained degradation of a protein called NEK7 in peripheral blood T cells—we're talking around 80% to 90% degradation across all dose levels. That's the mechanism of action working as intended.

More importantly for patients, the drug led to significant reductions in serum hsCRP (high-sensitivity C-reactive protein, a key inflammation marker) across all dose levels. This happened both after single doses and after seven days of multiple dosing.

In the multiple ascending dose cohorts, MRT-8102 produced marked suppression of IL-1β secretion in patients who started with elevated CRP levels. When researchers looked at high CRP subjects across all dose levels, they found significant reductions in endogenous IL-6, with median IL-6 levels dropping by 55% to levels below the cardiovascular risk threshold. That's a meaningful change.

Here's something unexpected: in two subjects with elevated baseline levels of cerebrospinal fluid IL-6, researchers observed a 75% decrease in CSF IL-6. Interestingly, these two subjects had low plasma IL-6 levels at baseline, which might suggest MRT-8102 has specific effects on the central nervous system or CSF that weren't originally anticipated.

The Cardiovascular Risk Data

In Part 3 of the study—the cohort that actually matters most for cardiovascular applications—MRT-8102 achieved an 85% decrease in hsCRP after four weeks of dosing. The placebo group showed no significant change, which is exactly what you want to see in a controlled trial.

Even more impressive: 94% of subjects who received the drug suppressed their hsCRP levels to below 2mg/L after four weeks. That threshold is clinically significant because it's associated with reduced cardiovascular disease risk.

On the safety front, the drug showed a favorable profile with only mild to moderate adverse events and no evidence of increased infection risk—an important consideration for any drug that messes with your immune system.

What Comes Next

Monte Rosa has mapped out an ambitious timeline for 2026. The company expects topline results from the Phase 1 GFORCE-1 study of MRT-8102 in subjects with elevated cardiovascular disease risk in the second half of next year.

The company also plans to initiate the Phase 2 GFORCE-2 trial of MRT-8102 in patients with atherosclerotic cardiovascular disease during 2026—moving from people at risk to people who actually have the disease.

Beyond MRT-8102, Monte Rosa has other irons in the fire. The company expects its collaborator Novartis AG (NVS) to advance MRT-6160, a VAV1-directed molecular glue degrader, into multiple Phase 2 studies across immune-mediated diseases in 2026.

Cancer Pipeline Progress

Monte Rosa isn't putting all its eggs in the inflammation basket. The company plans to advance its oncology pipeline by initiating the MODeFIRe-1 Phase 2 trial of MRT-2359 in 2026. That study will evaluate MRT-2359 combined with a second-generation androgen receptor inhibitor in patients with castration-resistant prostate cancer.

The company also expects to present updated clinical data from the ongoing Phase 1/2 study of MRT-2359 at the ASCO Genitourinary Cancers Symposium in February 2026.

GLUE Price Action: Monte Rosa Therapeutics shares jumped 53.28% to $24.54 at the time of publication Wednesday, hitting a new 52-week high.
