A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Ability to comprehend and willingness to sign a written ICF for the study.
- Aged 18 years or older at the time of signing the ICF.
- Histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas (as per American Joint Committee on Cancer 8th Edition. Note 1: Prescreening for participants with suspected PDAC is allowed. Note 2: Squamous, sarcomatoid, neuroendocrine (carcinoid, islet cell), and acinar pancreatic carcinoma are excluded.
- Documented KRAS G12D mutation in tumor tissue or blood (eg, ctDNA genetic testing). The following are acceptable: a. Presence of KRAS G12D mutation documented in participant medical record as detected in tumor tissue or blood (eg, ctDNA genetic testing) based on a sponsor-approved assay (PCR- or NGS-based only). b. Presence of KRAS G12D mutation determined prior to screening by local laboratory assay or sponsor-approved assay (PCR- or NGS-based only) qualified per national country regulations and performed on tumor tissue or blood using sponsor-permitted methods and laboratories.
- No prior systemic treatment for metastatic PDAC. Note: Participants who previously received therapy for nonmetastatic disease may enroll if no systemic treatment was administered within 6 months before randomization into the study.
- Radiographically measurable disease (based on local site investigator/radiology evaluation) per RECIST v1.1 criteria, evidenced by available baseline imaging. Note 1: Target lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions. Note 2: Tumor lesions that have been biopsied should not be selected as target lesions unless postbiopsy imaging confirms that they still qualify as RECIST-defined measurable lesions.
You likely can't join if
- Receipt of prior systemic or local (eg, surgery, radiotherapy) treatment of metastatic PDAC with the exception of treatment for nonmetastatic disease administered ≥ 6 months prior to Cycle 1 Day 1. Note 1: Prior placement of a biliary stent/tube is permitted if performed ≥ 7 days prior to randomization. Note 2: Receipt of prior palliative radiotherapy is permitted. A 1-week washout is required for prior palliative radiation.
- Women who are pregnant or breastfeeding.
- Any condition that would, in the investigator's judgment, interfere with full participation in the study, including administration of study treatment and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data.
- Known additional malignancy that is progressing or requires active treatment, or history of other malignancy within 2 years before the first dose of study treatment. Exceptions include: Cured basal cell or squamous cell carcinoma of the skin, prostate intraepithelial neoplasm, Bowen's disease or prostate cancer with a Gleason score ≤ 6, superficial bladder cancer, carcinoma in situ of the cervix, or other non-invasive or indolent malignancy, or cancers from which the participant has been disease-free for > 1 year after treatment with curative intent.
- The following participants are excluded in France: vulnerable populations according to article L.1121-6 of the French Public Health Code and adults under legal protection, or who are unable to express their consent per article L.1121-8 of the French Public Health Code, not affiliated to a social security per article L.1121-8-1 of the French Public Health Code.
- Untreated and/or progressing CNS metastases (eg, evidence of new or enlarging brain metastasis or new neurological symptoms attributable to brain or CNS metastases). Note: Participants with previously treated and clinically stable brain or CNS metastases are eligible if all of the following apply: a. Central nervous system metastasis treatment has been completed at least 2 weeks prior to screening CNS imaging. b. Any neurologic symptoms have returned to baseline. c. There is no evidence of new or enlarging CNS metastasis or leptomeningeal disease or clinically significant CNS edema or hemorrhage. d. Corticosteroids have not been required for symptoms of CNS metastases or toxicities of CNS metastasis treatment for at least 7 days before the first dose of study treatment.
