Does neoadjuvant treatment with AK112 plus chemotherapy improve the pathological complete response (pCR) rate compared to chemotherapy alone in patients with locally advanced G\u002FGEJ adenocarcinoma with signet ring cells?\n2. What are the safety profile and additional efficacy outcomes of AK112 combined with chemotherapy in this patient population?\n\nTo answer these questions, the study will compare the combination of AK112 and chemotherapy with chemotherapy alone.\n\nParticipant Procedures\n\nEligible participants will:\n\n1. Receive standard-dose AK112 in combination with chemotherapy every 3 weeks for a total of 4 cycles prior to surgery.\n2. Undergo preoperative CT or MRI imaging within 3-4 weeks after the last treatment cycle to assess tumor response and evaluate eligibility for curative resection.\n3. If no evidence of disease progression is observed and surgical evaluation is favorable, patients will undergo curative-intent gastrectomy within 6 weeks of completing neoadjuvant therapy (including oral agents, if any).\n4. Postoperatively, adjuvant therapy will be administered at the investigator's discretion. Patients will be followed until disease recurrence or metastasis.\n5. Attend clinic visits every 6 weeks during the neoadjuvant phase for evaluations and laboratory tests.\n6. Maintain a symptom diary throughout the study period.\n7. Undergo follow-up assessments every 3 months, starting from the first dose of study medication until 30 days after the last dose or the initiation of a new anti-tumor therapy.\n\nOptional Imaging Substudy FAPI-PET\u002FCT imaging will be explored as an optional diagnostic modality. Participation in this substudy will require separate informed consent and will be conducted under a future protocol amendment (pending IRB approval).",[28],"2025-07-21",{"date":289,"type":33},"2025-07-29",{"date":291,"type":22},"2025-07-20",{"date":293,"type":22},"2029-07-20",{"name":295,"class":40},"Peking Union Medical College Hospital",{"id":297,"slug":298,"hasResults":11,"nctId":299,"briefTitle":300,"officialTitle":301,"acronym":4,"eligibilityCriteria":302,"healthyVolunteers":11,"sex":17,"minAge":18,"maxAge":4,"enrollmentInfo":303,"targetDuration":4,"studyType":23,"phases":305,"briefSummary":306,"conditions":307,"keywords":308,"overallStatus":127,"whyStopped":4,"lastUpdateSubmitDate":316,"lastUpdatePostDateStruct":317,"startDateStruct":319,"completionDateStruct":321,"leadSponsor":323,"locationsCount":91},"100561227","phase-2-the-efficacy-and-safety-of-lm-302-in-combination-with-candonilimab-and-capecitabine-for-first-line-treatment-in-patients-with-unresectable-advanced-recurrent-or-metastatic-cldn182-positive-gastric-or-gastroesophageal-junction-adenocarcinoma-100561227","NCT06587425","The Efficacy and Safety of LM-302 in Combination With Candonilimab and Capecitabine for First-Line Treatment in Patients With Unresectable Advanced, Recurrent, or Metastatic CLDN18.2-Positive Gastric or Gastroesophageal Junction Adenocarcinoma","A Phase II Study Evaluating the Efficacy and Safety of LM-302 in Combination With Candonilimab and Capecitabine for First-Line Treatment in Patients With Unresectable Advanced, Recurrent, or Metastatic CLDN18.2-Positive Gastric or Gastroesophageal Junction Adenocarcinoma","Inclusion Criteria:\n\n* The subjects fully understand the purpose, nature, methods, and potential adverse reactions of the trial, voluntarily participate as participants, and sign an informed consent form (ICF) before any procedures begin\n* The subject must have locally advanced or metastatic gastric cancer or gastroesophageal junction cancer that cannot be surgically removed, and the histopathological examination confirms it to be simple adenocarcinoma\n* Permissible Previous Treatment: Participants with gastric cancer or gastroesophageal junction cancer who have previously received adjuvant or neoadjuvant treatment and have experienced clinical disease progression at least 6 months after the last administration are eligible for inclusion.
