Pancreatic Adenocarcinoma (Ductal Adenocarcinoma)

Pancreatic ductal adenocarcinoma (PDAC) is diagnosed at an advanced, incurable stage in more than 80% of cases in Switzerland. Certain warning signs - new-onset diabetes, unexplained weight loss, or a family history of pancreatic cancer - may indicate elevated risk, but are not systematically assessed in primary care. PANCATCH-Pilot tests whether a structured case-finding pathway in Swiss general practices is feasible. Adults aged 60 years or older with one or more of these risk factors are invited to undergo an MRI/MRCP examination of the pancreas and a blood draw for a blinded biomarker test (PancreaSure, Immunovia Inc.). Findings are reviewed by a multidisciplinary tumour board. The goal is not treatment, but to assess whether such a pathway works in the Swiss primary care context - as preparation for a larger national study. The study enrolls 50 trigger-positive participants over 24 months through two parallel recruitment pathways: GP referral and self-presentation via a study website. Feasibility is assessed using six combined endpoints covering recruitment, process quality, safety, and equity.

The investigational product used in this study, UCLH801 cells, is a CAR-T cell therapy specifically targeting CDH17. The proposed indication includes CDH17-positive advanced solid tumors, such as but not limited to colorectal cancer, gastric cancer, pancreatic cancer, biliary tract tumors, neuroendocrine tumors, ovarian cancer, and lung cancer. The primary objective of this study is to evaluate the safety and tolerability of UCLH801 cells in patients with CDH17-positive advanced malignant solid tumors. The secondary objectives include assessing the preliminary efficacy of UCLH801 cells, their pharmacokinetics and pharmacodynamics in the body, and their immunogenicity. This study aims to observe how the infusion of UCLH801 cells affects patients 's body, including any discomfort or changes in laboratory test results. Additionally, it will evaluate whether UCLH801 cells have any effect on tumor. Furthermore, the study will investigate how UCLH801 cells are metabolized; the mechanisms through which they exert their effects, and how to develops any immune response or rejection against UCLH801 cells.

Study LCB-1801-001 is an open-label, Phase 1, dose escalation (Part A) and expansion (Part B), first-in-human clinical study of NI-1801 in patients with advanced, metastatic, or recurrent solid malignancies expressing mesothelin (MSLN). The dose escalation part (Part A) of the main study will evaluate the safety and tolerability of escalating doses of NI-1801 to determine the maximum tolerated dose (MTD) and non-tolerated toxic dose (NTD) of NI-1801. The expansion part (Part B) of the main study will further evaluate the safety and efficacy of NI-1801 administered at or below the MTD in up to 10 additional subjects in order to determine the recommended Phase 2 dose (RP2D). Treatments will be administered in 28-day cycles for up to 12 months until disease progression, unacceptable toxicity, or Investigator/patient decision to withdraw study consent. The dose escalation part (Part A) of the sub-study will evaluate the safety and tolerability of escalating doses of NI-1801 in combination with anti-PD-1 antibody. The expansion part (Part B) of the sub-study will further evaluate the safety and efficacy of NI-1801 administered in combination with anti-PD-1 antibody at or below the MTD. In the randomized cohort, the experimental arm will receive the investigational drug NI-1801 at the P2RD every two weeks in combination with weekly administration of paclitaxel (80 mg/m\^2) over 4-week cycles. The control arm will be treated with weekly paclitaxel at the same regimen representing one of the standards of care (SoC) in this population. This trial specifically targets patients with platinum-resistant ovarian cancer. This cohort will be made up of 20 evaluable patients, 10 per arm.
