About this trial
This study aims to assess the efficacy and safety of a combination therapy consisting of Anlotinib, TQB2450 (a PD-L1 inhibitor), and Albumin-bound Paclitaxel regimens in patients with advanced gastric cancer (GC) or gastroesophageal junction adenocarcinoma (GEJA) who have failed the previous treatment with Claudin18.2 (CLDN18.2)-related regimens.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Voluntarily join this study, sign the informed consent form, and have good compliance;
Pathologically (histologically or cytologically) confirmed HER2/neu-negative (or HER2/neu status unclear) advanced gastric cancer or gastroesophageal junction adenocarcinoma;
Patients who have failed first-line treatment with CLDN18.2-related regimen (CLDN18.2 drugs include CLDN18.2 monotherapy, CLDN18.2 dual therapy, CLDN18.2 ADC or CLDN18.2 CART therapy, treatment regimen includes CLDN18.2 combined with chemotherapy or immunotherapy or other systemic therapy) and the time from the end of the last treatment with CLDN18.2-related drugs is more than two weeks;
According to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, at least one measurable lesion, which can be accurately measured in at least one direction (the maximum diameter needs to be recorded) by magnetic resonance imaging (MRI) or computed tomography (CT), with the longest diameter at baseline ≥10 mm (if it is a lymph node, the short diameter is required to be ≥15 mm); the measurable lesions should not have received local treatment such as radiotherapy (lesions in the previous radiotherapy area, if confirmed to have progressed and meet the RECIST 1.1 criteria, can also be selected as target lesions);
Disqualifiers
Have any active autoimmune disease or history of autoimmune disease (such as but not limited to autoimmune hepatitis, interstitial pneumonia, enteritis, vasculitis, nephritis; requiring bronchodilators for medical intervention of asthma); but the following patients are allowed to enroll: vitiligo, psoriasis, alopecia that do not require systemic treatment, type I diabetes that is well controlled, hypothyroidism that has normal thyroid function after replacement therapy;
Diagnosed with immunodeficiency or receiving systemic corticosteroid therapy or any other form of immunosuppressive therapy (dose >10mg/day of prednisone or other equivalent hormones), and continuing to use it within 2 weeks before the first administration;
Received any live vaccine, attenuated vaccine (including anti-infective vaccines, such as influenza vaccine, varicella vaccine, etc.), or inactivated vaccine within 4 weeks before enrollment and plan to receive live vaccine/attenuated vaccine/inactivated vaccine during the study; used systemic immunostimulants (including but not limited to interferon and IL-2) within 2 weeks before the start of the study treatment;
Patients who have received anti-tumor treatment with traditional Chinese medicine within the past two weeks (the traditional Chinese medicine contains the following medicinal materials such as Brucea javanica, Coix seed, Lentinan, Cantharidin, Toad skin, Astragalus, Sophora, Ugonin, Chebula, Icariin, etc.), but patients who have stopped taking anti-tumor treatment with traditional Chinese medicine for more than two weeks are allowed to enroll;
