Umirolimus is a semi-synthetic macrocyclic lactone and a derivative of rapamycin that has immunosuppressive and anti-inflammatory effects. It halts the cell cycle at the G1 phase through an IL-2/mTOR-mediated pathway and inhibits proliferation of human smooth muscle cells. In a porcine overstretch model, coronary stents containing umirolimus for localized delivery to the vessel wall reduced stenosis by 50% and led to less thickening of the vessel wall than a bare metal stent. Rapamycin, and likely its derivatives, binds to the cytosolic FK-binding protein 12 (FKBP12) to inhibit the mammalian target of rapamycin (mTOR) pathway. Formulations containing umirolimus have been used in coronary stents for localized delivery to the vessel wall.

Structural Aspects of mTOR Inhibitors: Search for Potential Compounds
Anticancer Agents Med Chem 2022;22(6):1037-1055.PMID:34288843DOI:10.2174/1871520621666210720121403.
mTOR (mammalian target of rapamycin) is a catalytic subunit composed of two multi-protein complexes that indicate mTORC1 and mTORC2. It plays a crucial role in various fundamental cell processes like cell proliferation, metabolism, survival, cell growth, etc. Various first line mTOR inhibitors such as Rapamycin, Temsirolimus, Everolimus, Ridaforolimus, Umirolimus, and Zotarolimus have been used popularly. In contrast, several mTOR inhibitors such as Gedatolisib (PF-05212384) are under phase 2 clinical trials studies for the treatment of triple-negative breast cancer. The mTOR inhibitors bearing heterocyclic moieties such as quinazoline, thiophene, morpholine, imidazole, pyrazine, furan, quinoline are under investigation against various cancer cell lines (U87MG, PC-3, MCF-7, A549, MDA-231). In this review, we summarized updated research related to mTOR inhibitors and their structure-activity relationship, which may help scientists develop potent inhibitors against cancer.
Polymer-free Drug-Coated Coronary Stents in Patients at High Bleeding Risk
N Engl J Med 2015 Nov 19;373(21):2038-47.PMID:26466021DOI:10.1056/NEJMoa1503943.
Background: Patients at high risk for bleeding who undergo percutaneous coronary intervention (PCI) often receive bare-metal stents followed by 1 month of dual antiplatelet therapy. We studied a polymer-free and carrier-free drug-coated stent that transfers Umirolimus (also known as biolimus A9), a highly lipophilic sirolimus analogue, into the vessel wall over a period of 1 month. Methods: In a randomized, double-blind trial, we compared the drug-coated stent with a very similar bare-metal stent in patients with a high risk of bleeding who underwent PCI. All patients received 1 month of dual antiplatelet therapy. The primary safety end point, tested for both noninferiority and superiority, was a composite of cardiac death, myocardial infarction, or stent thrombosis. The primary efficacy end point was clinically driven target-lesion revascularization. Results: We enrolled 2466 patients. At 390 days, the primary safety end point had occurred in 112 patients (9.4%) in the drug-coated-stent group and in 154 patients (12.9%) in the bare-metal-stent group (risk difference, -3.6 percentage points; 95% confidence interval [CI], -6.1 to -1.0; hazard ratio, 0.71; 95% CI, 0.56 to 0.91; P<0.001 for noninferiority and P=0.005 for superiority). During the same time period, clinically driven target-lesion revascularization was needed in 59 patients (5.1%) in the drug-coated-stent group and in 113 patients (9.8%) in the bare-metal-stent group (risk difference, -4.8 percentage points; 95% CI, -6.9 to -2.6; hazard ratio, 0.50; 95% CI, 0.37 to 0.69; P<0.001). Conclusions: Among patients at high risk for bleeding who underwent PCI, a polymer-free umirolimus-coated stent was superior to a bare-metal stent with respect to the primary safety and efficacy end points when used with a 1-month course of dual antiplatelet therapy.

Comparison of Biolimus Versus Everolimus for Drug-Eluting Stents in the Percutaneous Treatment of Infra-Inguinal Arterial Disease
Curr Vasc Pharmacol 2017;15(3):257-264.PMID:28117007DOI:10.2174/1570161115666170123094523.
Background: Drug-eluting stents (DES) are now considered the most promising device to treat peripheral artery disease (PAD) and minimize restenosis. There is uncertainty however on the best antirestenotic drug for such devices. In particular, biolimus (i.e. Umirolimus) and everolimus are two of the most promising agents, given the extensive data in support of their coronary safety and efficacy, but their comparative effectiveness for peripheral interventions is not established. Methods: Building upon our extensive experience in the percutaneous treatment of infra-inguinal artery disease with DES, we compared the acute and longterm outlook of patients treated with biolimus-eluting stents (BES) and everolimus-eluting stents (EES). We collected baseline, procedural and outcome details on all patients undergoing infra-inguinal BES or EES implantation. The endpoints of interest were death, amputation, revascularization, their composite, and change in Fontaine class. A total of 80 patients were included (20 treated with BES and 60 with EES). Most features were similar in the two groups, despite longer lesions in the EES group. Unadjusted analysis showed similar results irrespective of the drug used, with composite endpoint occurring, respectively, in 4 (20.0%) and 10 (16.7%) (p=0.741). Results and conclusion: However, analysis with inverse probability of treatment weighting showed significant differences in the risk of revascularization (hazard ratio of BES vs EES=9.55 [95% confidence interval 2.16-42.23], p=0.003) and composite endpoint (hazard ratio=5.11 [1.33-19.62], p=0.018). In conclusion, EES appear superior to BES for endovascular therapy of infrainguinal artery disease. Dedicated randomized trials are required to definitely confirm or disprove these findings.
