Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  1. Sign the written informed consent form (ICF) and be willing and able to comply with the visits and related procedures stipulated in the plan.
  2. Histologically confirmed unresectable locally advanced, or metastatic pancreatic cancer.
  3. Have received and progression after at least two systemic therapies(must including a fluorouracil-based and a gemcitabine-based therapy).
  4. ECOG PS score of 0 or 2.
  5. Adequate bone marrow and organ function
  6. Confirmed as CLDN18.2 positive.

Exclusion Criteria:

  1. Participation in another interventional study, except observational or post-intervention follow-up.
  2. Prior treatment with topoisomerase inhibitor-based ADC.
  3. Has received the last dose of an anti-cancer therapy within 2 weeks or 5 half-lives (whichever is shorter) prior to the first dose of study treatment.
  4. Plans to receive other anti-tumor treatments during treatment with the study drug (palliative radiotherapy for symptomatic (e.g., pain) relief that does not affect response assessment is allowed) .
  5. Symptomatic CNS metastasis; asymptomatic brain metastases may be allowed with specific criteria.
  6. History of other primary malignancies, except cured or low-risk of recurrence.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
overall survival(OS)
Time Frame: approximately 24 months
Overall survival (OS) is defined as the time from randomization to death from any cause.
approximately 24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
