BackgroundCitarinostat (CC-96241; previously ACY-241), an oral inhibitor of histone deacetylases (HDACs) with selectivity for HDAC6, has demonstrated synergistic anticancer activity with paclitaxel in multiple solid tumor models. Combination therapy using citarinostat with paclitaxel was evaluated in this phase Ib 3 + 3 dose-escalation study in patients with advanced solid tumors.MethodsPatients with previously treated advanced solid tumors received citarinostat 180, 360, or 480 mg once daily on days 1 to 21 plus paclitaxel 80 mg/m2 on days 1, 8, and 15 of 28-day cycles until disease progression or unacceptable toxicity. The primary endpoint was determination of the maximum tolerated dose (MTD). Secondary endpoints included safety, antitumor activity, pharmacokinetics, and pharmacodynamics.ResultsTwenty patients were enrolled and received study treatment; 15 had received prior taxane therapy. No dose-limiting toxicities were reported at any dose; therefore, the MTD was not identified. Citarinostat 360 vs 480 mg was associated with reduced incidence and severity of neutropenia. Three patients experienced a confirmed partial response and 13 achieved stable disease. Pharmacokinetic parameters were linear up to citarinostat 360 mg, the dose at which the highest levels of histone and tubulin acetylation were observed in peripheral blood mononuclear cells.ConclusionsThe combination of citarinostat plus paclitaxel showed an acceptable safety profile, with no unexpected or dose-limiting toxicities and potential evidence of antitumor activity in patients with heavily pretreated advanced solid tumors. Citarinostat 360 mg once daily is considered the recommended phase II dose for use in combination with paclitaxel 80 mg/m2 every 3 of 4 weeks. This trial is registered on ClinicalTrials.gov (NCT02551185).

Abstract Background:Natural killer cells are innate cytotoxic lymphocytes that play an important role in the anti-tumor immune response. However, in the microenvironment of solid tumors, the effector functions of NK cells are often impaired by the induction of immune checkpoint inhibitors, including PD-1. Methods: In this study, we conducted a two-phase study treating advanced solid patients with NK cell therapy (phase 1) or NK and anti-PD-1 inhibitor, pembrolizumab (phase 2).Results: After treatment, only 3 of 9 patients achieved stable disease after accepting NK cell therapy in the phase 1 study. While in the phase 2 study, 4 patients achieved stable diseases and 1 patient achieved partial response. Remarkably, no severe adverse event was observed in patients treated by NK cell and pembrolizumab combination therapy.Conclusion: The results in our study indicated that immune combination therapy with NK cell and pembrolizumab might be a promising and safe approaches to treating advanced solid tumors.
