Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Some people with pancreatic ductal cancer (PDAC) have a protein called Claudin 18.2 (CLDN18.2) in their tumor. ASP2138 is thought to work by binding to CLDN18.2 and a protein on a type of immune cell called a T-cell. The T-cell "tells" the immune system to attack the tumor. This study is for people with resectable PDAC. Resectable means that the tumor can be removed by surgery. In this study, adults with resectable PDAC will receive an ASP2138 injection just below the skin (subcutaneous) a few weeks before surgery. After surgery, they will be given standard chemotherapy treatments chosen by their study doctor. These include mFOLFIRINOX, gemcitabine with nab-paclitaxel, or gemcitabine with capecitabine. People will receive chemotherapy treatment for up to 6 months, or until their cancer gets worse, they cannot tolerate the chemotherapy, or they or their study doctor thinks they should stop chemotherapy. People will have a final clinic visit about a month after finishing chemotherapy for health checks.

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.

Ages Eligible for Study:18 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Participant has histologically confirmed localized pancreatic adenocarcinoma which is deemed upfront resectable based on institutional multi-disciplinary review. Participant with localized pancreatic adenocarcinoma cannot have received any prior therapy.
  2. * Participant has confirmation of positive claudin (CLDN)18.2 test result by local laboratory prior to first dose of study intervention (1 dose of ASP2138 may be allowed after discussion with the medical monitor, if results are pending). Site should contact the sponsor to assess potential eligibility based on a local test result.
  3. * Participant has an available pretreatment tumor sample which meets requirements.
  4. * Participant is able to undergo surgery and treatment with adjuvant chemotherapy per institutional standard of care.
  5. * Participant with a known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function of class 2B or better using the New York Heart Association Functional Classification.
  6. * Female participant is not pregnant and at least 1 of the following conditions apply:
  7. * Not a woman of childbearing potential (WOCBP)
  8. * WOCBP who has a negative serum pregnancy test at screening and agrees to follow the contraceptive guidance from the time of informed consent through at least 6 months after final ASP2138 intervention administration (or follow the contraception requirements per the adjuvant chemotherapy package insert \[PI\]/prescribing information, whichever is longer).
  9. * Female participant must not be breastfeeding or lactating starting at screening and throughout the investigational period and for 5 half-lives (6 months) after final ASP2138 intervention administration (or follow the contraception requirements per the adjuvant chemotherapy PI/prescribing information, whichever is longer).
  10. * Female participant must not donate ova starting at first administration of neoadjuvant ASP2138, throughout the investigational period, and for 6 months after final ASP2138 administration (or follow the contraception requirements per the adjuvant chemotherapy PI/prescribing information, whichever is longer).
  11. * Male participant must agree to use contraception with female partner(s) of childbearing potential (including breastfeeding partner) throughout the treatment period and for 6 months after final ASP2138 intervention administration (or follow the contraception requirements per the adjuvant chemotherapy PI/prescribing information, whichever is longer).
  12. * Male participant must agree to remain abstinent or use a condom with pregnant partner(s) for the duration of the pregnancy throughout the investigational period and for 6 months after final ASP2138 intervention administration (or follow the contraception requirements per the adjuvant chemotherapy PI/prescribing information, whichever is longer).
  13. * Male participant must not donate sperm during the treatment period and for 6 months after ASP2138 intervention administration (or follow the contraception requirements per the adjuvant chemotherapy PI/prescribing information, whichever is longer).
  14. * Participant has at least 1 measurable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 within 28 days prior to the first dose of study intervention per investigator assessment.
  15. * Participant has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  16. * Participant has a corrected QT interval by Fridericia (QTcF) ≤ 470 msec.
  17. * Participant must meet all of the criteria based on laboratory tests within 7 days prior to the first dose of study intervention. Participant has adequate organ and marrow function. If a participant has received a recent blood transfusion, the laboratory tests must be obtained ≥ 1 week after any blood transfusion.
  18. * Participant agrees not to participate in another interventional study while receiving study intervention in the present study.
  1. * Participant has had within 6 months prior to first dose of study intervention any of the following: unstable angina, myocardial infarction, ventricular arrhythmia requiring intervention or hospitalization for heart failure.
  2. * Participant has active infection requiring systemic therapy that has not completely resolved within 7 days prior to the start of study intervention.
