Phase I dose-escalation study of nab-paclitaxel combined with cisplatin and capecitabin as induction chemotherapy followed by concurrent chemoradiotherapy in patients with nasopharyngeal carcinoma.

BACKGROUND AND PURPOSE: Nab-paclitaxel is a promising albumin-bound paclitaxel with a therapeutic index superior to that of docetaxel, but the optimal dose of nab-paclitaxel combined with cisplatin and capecitabine as induction chemotherapy followed by concurrent chemoradiotherapy for patients with locally advanced nasopharyngeal carcinoma remains unknown. MATERIALS AND METHODS: This was an open-label, single-arm study investigating the safety and efficacy of nab-paclitaxel + cisplatin + capecitabin as IC for three cycles, followed by cisplatin CCRT, conducted by using the standard "3 + 3" design in LA-NPC. If more than one-third of the patients in a cohort experienced dose-limiting toxicity (DLT), the dose used in the previous cohort was designated the maximum tolerated dose (MTD). The recommended phase 2 dose (RP2D) was defined as one level below the MTD. RESULTS: From 29 May 2021 to 17 March 2022, 19 patients with LA-NPC were enrolled, one patient withdrew informed consent. Two DLTs occurred in cohort 4 (grade 4 febrile neutropenia and grade 3 peripheral neuropathy), and an MTD was established as 225 mg/m2. The most frequent grade 3 or 4 adverse events were neutropenia (16.7 %), hypertriglyceridemia (16.7 %), leukopenia (5.6 %) and peripheral neuropathy (5.6 %) during IC. CONCLUSION: The RP2D is nab-paclitaxel 200 mg/m2 on day 1, combined with cisplatin 75 mg/mg2 on day 1 and capecitabin1000 mg/m2 on days 1-14, twice a day, every 3 weeks, for three cycles as an IC regimen prior to CCRT.

ZIF-8-Based Quasi-Solid-State Electrolyte for Lithium Batteries.

The quasi-solid-state electrolytes (QSSEs) with an inorganic skeleton, a solid-liquid composite material combining their respective merits, exhibit high ionic conductivity and mechanical strength. However, most quasi-solid electrolytes prepared by immobilizing ionic liquid (IL) or organic liquid electrolyte in inorganic scaffold generally have poor interface compatibility and low lithium ion migration number, which limits its application. Herein, we design and prepare a ZIF-8-based QSSE (ZIF-8 QSSE) in which the ZIF-8 has a special cage structure and interaction with the guest electrolyte to form a composite electrolyte with good ionic conductivity about 1.05 × 10-4 S cm-1 and a higher lithium-ion transference number of about 0.52. With the ZIF-8 QSSE, a protype lithium battery coupled with LiCoO2 cathode shows good electrochemical performances with an initial discharge capacity of 135 mAh g-1 at 50 mA g-1 and a remaining capacity of 119 mAh g-1 after 100 cycles, only 0.119% capacity degradation per cycle. It is worth noting that the ZIF-8-based QSSEs have good thermal stability up to 350 °C that does not show thermal runaway, which is significantly higher than that of a conventional organic liquid battery system.
