Purpose: The study aims to investigate the absorption, metabolism, and excretion of donafenib, a deuterated derivative of sorafenib, in healthy Chinese male volunteers.
Methods: Six healthy Chinese male volunteers were administered a single oral dose of 300 mg donafenib containing 120 µCi of [14 C]-donafenib. The study involved collecting and analyzing plasma, urine, and feces samples to determine the recovery and distribution of total radioactivity, identify metabolites, and assess the metabolic pathways of donafenib.

Purpose: A noninvasive method for evaluating the infiltration of CD8 T cells in tumors is urgently needed to monitor the response to immunotherapy. This study investigated the performance of a [Ga]Ga-NODAGA-SNA006 in positron emission tomography (PET) imaging of CD8 T cells in patients with solid malignancies.
Methods: This human dose-escalation PET imaging study involved eleven patients (lung cancer, 8; gastric carcinoma, 1; esophageal carcinoma, 2).

Jaktinib is a novel Janus kinase (JAK) inhibitor, and a phase I clinical trial of single-dose Jaktinib was conducted in a population of subjects with hepatic impairment to assess the safety, tolerability, and pharmacokinetic characteristics of Jaktinib. The patients were administered orally with 100 mg Jaktinib on day 1 in all the mild hepatic impairment group (mild group, n = 8), moderate hepatic impairment group (moderate group, n = 8) and normal hepatic function group (normal group, n = 8), and the blood samples were collected for later analysis. The mild to moderate hepatic impairment affected the metabolism of Jaktinib, which may lead to accumulation of original Jaktinib.

Hu4G4 is a recombinant humanized antibody that selectively targets the extracellular domain of human B7-H3. In this study, we describe the radiolabeling of hu4G4 with the positron emission tomography (PET) emitter radionuclide zirconium 89 (Zr) and evaluate its potency as an immuno-PET tracer for B7-H3-targeted imaging by comparing it and to [Zr]Zr-DFO-DS-5573a using various models.

This study aimed to evaluate the relationship between early IFX levels and antibodies to infliximab (ATI) and CR at week 14 and simulate the probability of attaining the identified exposure target.
Methods: Patients with CD (n = 140) treated with IFX were enrolled to develop the popPK model.
Background And Objective: Tinengotinib, a novel multi-target small molecule kinase inhibitor, is currently undergoing phase II clinical trial in the USA and China. The purpose of this open-label study was to investigate the absorption, metabolism, and excretion of [C]tinengotinib following a single oral dose in healthy subjects.
Methods: Six healthy male subjects received a single oral dose of [C]tinengotinib capsules at 10 mg/100 µCi, and blood, urine, and feces samples were collected.
Bruton's tyrosine kinase inhibitors (BTKis) have revolutionized the treatment of B-cell lymphomas. However, safety issues related to the use of BTKis may hinder treatment continuity and further affect clinical efficacy. A comprehensive and systematic expert consensus from a pharmacological perspective is lacking for safety issues associated with BTKi treatment.

Numerous dose-prediction algorithms have been reported based on cross-sectional data generated via multiple linear regression or machine learning. This study aimed to construct an information fusion perturbation theory and machine-learning prediction model of warfarin blood levels based on clinical longitudinal data from cardiac surgery patients.

Methods: A single oral dose of 80 μCi (25 mg) [C]HSK7653 capsules was administered to six healthy participants, and blood, plasma, urine and faeces were collected. Quantitative and qualitative analysis was conducted to investigate the pharmacokinetics, blood-to-plasma ratio, mass balance and metabolism of HSK7653.
Tozorakimab is a high-affinity human immunoglobulin G1 monoclonal antibody that neutralizes interleukin (IL)-33, an IL-1 family cytokine. This phase 1, single-center, randomized, double-blind, placebo-controlled, single ascending dose study (NCT05070312) evaluated tozorakimab in a healthy Chinese population. Outcomes included the characterization of the pharmacokinetic (PK) profile and immunogenicity of tozorakimab.

This phase I mass balance study investigated the pharmacokinetics, metabolism, and excretion of C-radiolabeled envonalkib in healthy Chinese male subjects.
Methods: A single oral dose of 600 mg (150 µCi) [C]envonalkib was administered to healthy male subjects under fasted state.
Background: Warfarin is a widely prescribed anticoagulant in the clinic. It has a more considerable individual variability, and many factors affect its variability. Mathematical models can quantify the quantitative impact of these factors on individual variability.

In different animal models, Prusogliptin showed potential efficacy in the treatment of type 2 diabetes. However, the knowledge of its pharmacokinetics and safety in patients with liver dysfunction is limited.

A prospective, two-armed, single-blind, randomized controlled trial compared management aided by a web-based dose calculator (NextDose) with standard clinical care. Participants were 240 adults receiving warfarin therapy following cardiac surgery, followed up until the first outpatient appointment at least 3 months after warfarin initiation.

Background And Objective: HSK21542, a synthetic short-chain polypeptide, is a selective peripheral kappa opioid receptor (KOR) agonist. In this single-centre, non-randomized, open-label study, the pharmacokinetics, mass balance, metabolism and excretion of HSK21542 were investigated.
Methods: A single intravenous dose of 2 μg/0.
Radionuclide drug conjugates (RDCs) with antibodies serve as a novel approach for the treatment of malignant tumors including glioblastoma. However, RDCs require optimal antibodies to work efficiently. Hu4G4, a novel B7-H3-targeting humanized monoclonal IgG1 antibody, is highly specific for the human B7-H3 protein (a marker of tumor cells, including glioblastoma cells).

Methods: The pharmacokinetics and pharmacodynamics (PKPD) model predicted international normalized ratio (INR) and warfarin concentration. Serum and fecal samples were collected to detect warfarin and vitamin K [VK1 and menaquinone-4 (MK4)] concentrations and gut microbiota diversity, respectively.
