Outcomes with targeted therapy for NRAS-mutated melanoma: A systematic review and meta-analysis.
(ASCO 2025)
- "The targeted therapies investigated included Binimetinib (n = 299; 56.7%), Naporafenib plus Rineterkib (n = 29; 5%), Naporafenib plus Trametinib (n = 24; 4.5%), Trametinib (n = 17; 3.2%), Naporafenib plus Ribociclib (n = 15; 2.8%), and Binimetinib plus Bocodepsin (n = 9; 1.7%). Targeted therapies in NRAS-mutated melanoma show modest efficacy with frequent adverse effects. Innovative approaches, including novel therapeutic agents with different mechanisms of action, are urgently needed to improve clinical outcomes and address this unmet medical need."

Nautilus, a phase 1b/2 trial of combining oral HDAC inhibitor (HDACi) with MEK inhibitor (MEKi) in patients with NRAS-mutated metastatic melanoma (MM).
(ASCO 2025)
- P1/2 | "The combination of bocodepsin and binimetinib in patients with NRAS-mutant melanoma is tolerable with manageable AEs and no high grade rash. Initial response data in patients with NRAS-mutant melanoma are supportive of potential combinatorial activity of a MEK inhibitor and HDACi bocodepsin. Further investigation is crucial as MM patients with disease progression after immunotherapy remain in need of rational therapeutic options."

Combined Inhibition of Histone Deacetylases and Bromodomain Proteins Normalizes Gene Expression and Reverses Sugen/Hypoxia-induced Pulmonary Hypertension
(ATS 2024)
- "Cells were treated with HDACi (OKI-5) or BRDi (JQ1) or the combination of both. Combination of HDACi and BRDi in low doses is effective in normalizing the persistent activation of PH-Fibs and improving hemodynamics and pulmonary vascular remodeling in Sugen/hypoxia PH rats, offering promise for epigenetic-targeted combination therapies in PAH."

Overcoming doxorubicin resistance in triple-negative breast cancer using the class I-targeting HDAC inhibitor bocodepsin/OKI-179 to promote apoptosis.
(PubMed, Breast Cancer Res)
- "The addition of bocodepsin to doxorubicin resulted in synergistic antiproliferative activity in vitro, improved tumor growth inhibition in vivo, and promotion of apoptosis which makes this a promising combination to overcome doxorubicin resistance in TNBC. Bocodepsin is currently in clinical development and has a favorable toxicity profile compared to other HDAC inhibitors supporting the feasibility of evaluating this combination in patients with TNBC."

First-in-Human Dose-Escalation Study of the Novel Oral Depsipeptide Class I-Targeting HDAC Inhibitor Bocodepsin (OKI-179) in Patients with Advanced Solid Tumors
(Multidisciplinary Digital Publishing Institute)
- P1 | N=34 | NCT03931681 | Sponsor: OnKure, Inc. | "Patients (n = 34) with advanced solid tumors were treated with OKI-179 orally once daily in three schedules....The mean duration of treatment was 81.2 (range 11–447) days. The most frequent adverse events in all patients were nausea (70.6%), fatigue (47.1%), and thrombocytopenia (41.2%). The maximum tolerated dose (MTD) of OKI-179 was 450 mg with 4:3 and 200 mg with continuous dosing. Dose-limiting toxicities included decreased platelet count and nausea. Prolonged disease control was observed, including two patients with platinum-resistant ovarian cancer. Systemic exposure to the active metabolite exceeded the preclinical efficacy threshold at doses lower than the MTD and was temporally associated with increased histone acetylation in circulating T cells."

Elucidating the direct effects of the novel HDAC inhibitor bocodepsin (OKI-179) on T cells to rationally design regimens for combining with immunotherapy.
(PubMed, Front Immunol)
- "In vivo comparisons demonstrated that stopping OKI-179 treatment during PD-1 blockade was superior to continuous treatment. These findings provide novel insight into the direct effects of HDAC inhibitors on T cells and that treatment schedules that take into account acute T cell effects should be considered when combined with immunotherapies in order to fully harness the tumor-specific T cell responses in patients."

Theclass Iselective, oral HDAC inhibitor OKI-179 increases tumor regressions when combined with the MEK inhibitor binimetinib inmodels of NRAS melanoma
(AACR 2022)
- "Here we show synergistic activity of combining OKI-179 with the MEK inhibitor binimetinib (bini) or bini + RAF-inhibitor encorafenib (enco/bini) in both CDX and PDX models of NRAS-mutated melanoma and BRAF-mutated colorectal cancer (CRC). These data show the potential for OKI-179 to synergize with RAS-pathway inhibitors across multiple indications. To investigate, a Phase1b/2 trial of OKI-179 with binimetinib in NRAS melanoma will initiate in early 2022."

OKI-179 combined with binimetinib in NRAS-mutated melanoma or combined with binimetinib + encorafenib in BRAF-mutated colorectal xenografts showed significantly increased regressions compared to either single agent following two weeks of dosing."

The most common adverse events were nausea, fatigue and anemia. Nausea was manageable with antiemetics...Based on these favorable results, the Company expects to initiate a Phase 1b/2 trial of OKI-179 in combination with binimetinib in patients with NRAS mutant melanoma where checkpoint inhibitor therapy has failed in the first half of 2022."
