ClinConnect Summary

This clinical trial is studying a new treatment called IBI343 combined with chemotherapy for patients with advanced pancreatic cancer, specifically looking at its safety and effectiveness. The trial has two parts: the first part focuses on understanding how well the combination works and how patients tolerate it, while the second part will compare two different treatment groups to see which is more effective. To participate, patients must have a specific type of pancreatic cancer that has spread and must not be eligible for surgery or other radical treatments. They should also have at least one measurable tumor and be in good overall health.

Participants in this trial can expect to receive either the new treatment with IBI343 plus standard chemotherapy or just the standard chemotherapy. The study is not yet recruiting participants, but it is open to adults aged 18 and older who meet the eligibility criteria, which include having a confirmed diagnosis of advanced pancreatic cancer and being able to comply with the study's requirements. It’s important for potential participants to discuss the trial with their healthcare team to understand how it might fit into their treatment plan.

Eligibility criteria

• Inclusion Criteria:
• • Signed written informed consent, willing and able to comply with the protocol specified visits and related procedures.
• • Histopathologically confirmed unresectable locally advanced, recurrent, or metastatic pancreatic adenocarcinoma.
• • Subjects must not be eligible for radical treatment such as radical radiotherapy and / or surgery; time to disease recurrence / metastasis\> 6 months for subjects with previous (new) adjuvant / adjuvant / radiotherapy) chemotherapy / radical chemoradiotherapy. In part 1: locally advanced or recurrent / metastatic stage with or without systemic therapy (including chemotherapy, targeted therapy, tumor immunotherapy, etc.). In part 2: The locally advanced or recurrent / metastasis phase has not received any systemic therapy (including chemotherapy, targeted therapy, tumor immunotherapy, etc.).
• • At least 1 measurable lesion (no previous radiotherapy) for solid tumors RECIST v1.1.(At baseline, computed tomography or magnetic resonance imaging showed the long diameter of 10 mm (except for lymph nodes, the short axis of the lymph node must be 15 mm), the diameter of the target lesion is 2 times the imaging layer thickness and the lesion is suitable for repeated accurate measurement. If a lesion located in the previously irradiated area clearly demonstrates a progression meeting the RECIST V1.1 criteria, the lesion acts as a measurable lesion).
• • Age was 18 years, and gender was unlimited.
• • Eastern Cooperative Oncology Group Performance Status (ECOG PS) was 0 or 1.
• • The expected survival period was estimated at 12 weeks.
• • Sufficient bone marrow and organ function.

• • Is participating in another interventional clinical study, except for an observational (non-interventional) clinical study or is in the survival follow-up phase of the interventional study.
• • Treatment with a strong cytochrome P450 3A4 (CYP3A4) inhibitor within 2 weeks or 5 half-lives (whichever is longer) before the first dose of the study drug.
• • The last anti-tumor therapy within 4 weeks before the first dose of the study drug or within 5 half-lives of the anti-tumor treatment (whichever is shorter) (2 weeks for washout with no exact half-life).
• • Received therapeutic or palliative radiotherapy within 2 weeks prior to the first administration of the study drug.
• • Receiving biliary stenting or PTCD within 7 days prior to the first use of study drug.
• • Other anti-tumor treatment is planned during the study medication \[allows palliative radiotherapy for the purpose of relieving symptoms (e. g. pain) and does not affect efficacy evaluation\].

For the purpose of palliative care, the local surgical treatment of isolated lesions is acceptable.
• • Any live vaccine within 4 weeks before the first dose of the study drug or during the duration of the study.
• • A major surgical procedure (craniotomy, otomy, or tomy or otherwise defined by the investigator, excluding needle biopsy within 4 weeks before the first dose of study drug) or the presence of an unhealed wound, ulcer, or fracture; or a planned major surgery required during the study. For the purpose of palliative care, the local surgical treatment of isolated lesions is acceptable.
• • Failure to recover to grade 0 or 1 prior to the first dose of study drug of NCI CTCAE v5.0 (excluding alopecia, fatigue, pigmentation, and other conditions with no safety risk as judged by the investigator).
