Article

Author: Huh, Ki Young ; Lee, SeungHwan ; Kim, Byungwook ; Yu, Kyung-Sang

AimsCG‐750 is an oral formulation of ivaltinostat, a newly developing histone deacetylase (HDAC) inhibitor. This study aimed to evaluate the pharmacokinetics (PK), pharmacodynamics (PD) and safety of an oral formulation (CG‐750) of ivaltinostat compared to an intravenous (IV) formulation (CG‐745).MethodsA randomized, double‐blind, placebo‐controlled study was conducted in three cohorts. Subjects received either CG‐745 (Cohorts 1 and 3: 125 mg; Cohort 2: 250 mg) or placebo followed by CG‐750 (Cohort 1: 125 mg; Cohort 2: 375 mg; Cohort 3: 750 mg) or placebo. Blood samples for PK and PD assessment were collected up to 72 h post‐dose. Histone H3 acetylation at sites K9, K9/K14 and K27 was assessed for area under the % acetylation induction versus time curve (AUEC).ResultsA total of 25 subjects were randomized, and 23 subjects completed the study (Cohort 1, n = 6; Cohort 2, n = 6; Cohort 3, n = 6; placebo, n = 5). The mean bioavailability of CG‐750 was 10.6% (range: 4.18%–21.33%) and displayed linear PK in the dose range of 125–750 mg. The comparison of AUEC between formulations and the evaluation of the dose–AUEC relationship were inconclusive, due to the small sample sizes and significant variability observed in PD markers. All adverse events (AEs) were transient and of mild or moderate intensity.ConclusionsThe oral formulation of ivaltinostat (CG‐750) was generally well tolerated after a single dose. CG‐750 displayed a mean bioavailability of 10.6%.

AbstractThis phase I/II study evaluated the safety and efficacy of a new histone deacetylase (HDAC) inhibitor, ivaltinostat, in combination with gemcitabine and erlotinib for advanced pancreatic ductal adenocarcinoma (PDAC). Patients diagnosed with unresectable, histologically confirmed PDAC who had not undergone previous therapy were eligible. Phase I had a 3 + 3 dose escalation design to determine the maximum tolerable dose (MTD) of ivaltinostat (intravenously on days 1, 8 and 15) with gemcitabine (1000 mg/m2 intravenously on days 1, 8 and 15) and erlotinib (100 mg/day, orally) for a 28‐day cycle. In phase II, patients received a six‐cycle treatment with the MTD of ivaltinostat determined in phase I. The primary endpoint was the objective response rate (ORR). Secondary endpoints included overall survival (OS), disease control rate (DCR) and progression‐free survival (PFS). The MTD of ivaltinostat for the phase II trial was determined to be 250 mg/m2. In phase II, 24 patients were enrolled. The median OS and PFS were 8.6 (95% confidence interval [CI]: 5.3‐11.2) and 5.3 months (95% CI: 3.7‐5.8). Of the 16 patients evaluated for response, ORR and DCR were 25.0% and 93.8% with a median OS/PFS of 10.8 (95% CI: 8.3‐16.7)/5.8 (95% CI: 4.6‐6.7) months. Correlative studies showed that mutation burden detected by cfDNA and specific blood markers such as TIMP1, pro‐MMP10, PECAM1, proMMP‐2 and IGFBP1 were associated with clinical outcomes. Although the result of a small study, a combination of ivaltinostat, gemcitabine and erlotinib appeared to be a potential treatment option for advanced PDAC.

Inhibition of HDACs (Histone Deacetylases) Ameliorates High-Fat Diet–Induced Hypertension Through Restoration of the MsrA (Methionine Sulfoxide Reductase A)/Hydrogen Sulfide Axis

Q1 · MEDICINE

Article

Author: Kim, InKyeom ; Jang, GiBong ; Jung, Jin Ki ; Park, Kwon Moo ; Kim, Jee In ; Yoon, Ga-Eun

Hydrogen sulfide (H 2 S) is an endogenous gaseous antioxidant and antihypertensive molecule produced during the homocysteine metabolism. MsrA (methionine sulfoxide reductase A) enables the metabolism of homocysteine by reducing methionine sulfoxide to methionine. Although HDAC (histone deacetylase) inhibition has been reported to show blood pressure lowering effects, their effects on endogenous H 2 S production are largely unknown. Here, we assessed the relevance of MsrA in high-fat diet (HFD)-induced hypertension and the effect of HDAC inhibition on MsrA expression, H 2 S production, and hypertension. Male C57BL/6 mice were fed a normal diet or HFD. HFD increased blood pressure and activities of HDAC3 and 6 but downregulated MsrA in the mesenteric arteries and the serum H 2 S level. HFD upregulated 4 hydroxynonenal, TNF (tumor necrosis factor)-α, and IL (interleukin)-6, and vasocontractile proteins. The histone H3 acetylation of the MsrA promoter was decreased by HFD. In hypertensive HFD-fed mice, administration of the HDAC inhibitor CG200745 lowered blood pressure and increased serum H 2 S level. CG200745 increased acetylation of histone H3 and MsrA levels in the mesenteric arteries while downregulating oxidative stress, inflammation, and vasocontractile proteins. Silencing of MsrA in the vascular smooth muscle cells recapitulated HFD-induced in vivo hypertensive effects. CG200745 increased the histone H3 acetylation of the MsrA promoter, MsrA expression, and H 2 S production in vascular smooth muscle cells, supporting the in vivo results. Collectively, HFD-induced downregulation of MsrA plays a pivotal role in HFD-induced hypertension by reducing H 2 S levels. MsrA expression is epigenetically regulated by HDAC inhibitors, providing HDAC inhibitors as a therapeutic option and MsrA and H 2 S as novel therapeutic targets.

ORINDA, Calif., May 29, 2024 /PRNewswire/ -- CG Pharmaceuticals, a company dedicated to advancing innovative therapies to improve the lives of patients with cancer, prepares to showcase its advancements in metastatic PDAC therapy. The study design of a randomized multi-center Phase 2 US clinical trial, which is actively enrolling patients, is scheduled to be presented on June 1st, 1:30 – 4:30 PM CDT at the ASCO Annual Meeting (ClinicalTrials.gov NCT05249101). "Metastatic PDAC continues to be an aggressive cancer with limited treatment options. We are pleased that CG Pharmaceuticals is investing in pancreatic cancer research and look forward to the results of their trial," said Anna Berkenblit, MD, MMSc, Chief Scientific and Medical Officer at the Pancreatic Cancer Action Network (PanCAN). "Clinical trials are an important aspect of accelerating new developments that improve outcomes for pancreatic cancer patients. PanCAN recommends that patients with PDAC consider participating in clinical trials." In the Phase 1b study, 28 patients with locally advanced or metastatic PDAC who had received at least one prior line of therapy were administered ivaltinostat at three dose levels (60, 125, and 250 mg/m²) in combination with capecitabine. The study demonstrated a favorable safety profile, with no treatment-related serious adverse events. At the time of data cutoff (5/6/2024), 16 patients were alive with 3 patients continuing treatment, and 7 patients were treated for longer than 6 months with the longest duration of treatment of 16 months. The Phase 2 study compares the efficacy of ivaltinostat/capecitabine combination therapy versus capecitabine monotherapy in metastatic PDAC patients who have shown no evidence of disease progression after first-line chemotherapy. Efficacy endpoints include progression-free survival, objective response rate, disease control rate, and overall survival. About Ivaltinostat: Ivaltinostat is a potential first-in-class novel therapeutic candidate for PDAC that inhibits enzymatic activity of histone deacetylase and has been evaluated for solid tumors and hematologic malignancies.
