This single-center, open-label, non-randomized study aims to evaluate the pharmacokinetics, mass balance, and metabolic pathways of WX-081 (Sudapyridine) following a single oral dose of [U-14C] WX-081 in healthy Chinese male volunteers. A total of 6-10 subjects will be enrolled to obtain complete samples and data from at least six participants. Biological samples, including blood, plasma, urine, and feces, will be collected over a specified time period. The study will assess pharmacokinetic parameters, excretion pathways, and identify major metabolites contributing to over 10% of plasma exposure.

The goal of this clinical trial is to evaluate the safety and preliminary efficacy of WX390 combined with Toripalimab in patients with advanced Gastric-type Endocervical Adenocarcinoma with STK11 mutations. The main questions it aims to answer are:
* Pharmacokinetic (PK) characteristics of WX390 combined with Toripalimab treatment.
* Safety and preliminary in combined therapy. Participants will be treated with WX390 orally and Toripalimab intravenously, and follow the efficacy and safety evaluation according to the protocol.
