About This Trial

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For KRAS NP_004976.2:p.G12D, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 28 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: - Patients with diagnosed by tissue sample (biopsy-confirmed) metastatic pancreatic ductal adenocarcinoma harboring KrasG12D mutation - Patients must have documented progression or stable disease on one or more lines of systemic therapy. If stable disease, patient must have completed at least 4 months of chemotherapy with cytotoxic therapy - KrasG12D mutation status will be informed from any previous routine molecular profiling (using commercial assays such as Foundation One, Caris, Oncomine or other) of tissue or blood. Additional KrasG12D mutation status may be confirmed using tissue biopsy or blood prior to enrolling into the trial - ECOG (Eastern Cooperative Oncology Group) performance status of 0-1 - Absolute neutrophil count (ANC) more or equal to 1,500 cells/mm3 - Platelets more or equal to 100,000/ul - Hemoglobin more than 9.0 g/dL - Total bilirubin between 1 and 1.5 mg/dL - AST (aspartate aminotransferase) and ALT (alanine transaminase) less than 2.5 x ULN (upper limit of normal) - Alkaline phosphatase less than 2.5 x ULN - Creatinine less than 1.5 gm/dL - In patients with known Gilbert's syndrome, direct bilirubin less or equal to 1.5 x ULN will be used as organ function criteria, instead of total bilirubin - Negative serum pregnancy test in women with childbearing potential (WOCBP) defined as not post-menopausal for 12 months or no previous surgical sterilization, within one week prior to initiation of treatment. WOCBP must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 12 weeks after the last dose of study drug to minimize the risk of pregnancy. WOCBP must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 12 weeks after the last dose of study drug to minimize the risk of pregnancy ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Original Eligibility Criteria

Inclusion Criteria: * Patients with histologically confirmed metastatic pancreatic ductal adenocarcinoma harboring KrasG12D mutation * Patients must have documented progression or stable disease on one or more lines of systemic therapy. If stable disease, patient must have completed at least 4 months of chemotherapy with cytotoxic therapy * KrasG12D mutation status will be informed from any previous routine molecular profiling (using commercial assays such as Foundation One, Caris, Oncomine or other) of tissue or blood. Additional KrasG12D mutation status may be confirmed using tissue biopsy or blood prior to enrolling into the trial * ECOG (Eastern Cooperative Oncology Group) performance status of 0-1 * Absolute neutrophil count (ANC) more or equal to 1,500 cells/mm3 * Platelets more or equal to 100,000/ul * Hemoglobin more than 9.0 g/dL * Total bilirubin between 1 and 1.5 mg/dL * AST (aspartate aminotransferase) and ALT (alanine transaminase) less than 2.5 x ULN (upper limit of normal) * Alkaline phosphatase less than 2.5 x ULN * Creatinine less than 1.5 gm/dL * In patients with known Gilbert's syndrome, direct bilirubin less or equal to 1.5 x ULN will be used as organ function criteria, instead of total bilirubin * Negative serum pregnancy test in women with childbearing potential (WOCBP) defined as not post-menopausal for 12 months or no previous surgical sterilization, within one week prior to initiation of treatment. WOCBP must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 12 weeks after the last dose of study drug to minimize the risk of pregnancy. WOCBP must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 12 weeks after the last dose of study drug to minimize the risk of pregnancy * A male subject of fathering potential must use an adequate method of contraception to avoid conception throughout the study and for up to 12 weeks after the last dose of study drug to minimize the risk of pregnancy. If the partner is pregnant or breastfeeding, the subject must use a condom * Patients must sign an informed consent and authorization indicating that they are aware of the investigational nature of this study and the known risks involved Exclusion Criteria: * Concurrent severe and/or uncontrolled medical conditions which could compromise participation in the study such as unstable angina, myocardial infarction within 6 months, unstable symptomatic arrhythmia, uncontrolled diabetes, serious active or uncontrolled infection * Pregnancy (positive pregnancy test) or lactation * Known CNS (central nervous system) disease, except for treated brain metastasis. Treated brain metastases are defined as having no evidence of progression or hemorrhage after treatment and no ongoing requirement for dexamethasone, as ascertained by clinical examination and brain imaging (magnetic resonance imaging-MRI or computerized tomography-CT) during the screening period. Anticonvulsants (stable dose) are allowed. Treatment for brain metastases may include whole brain radiotherapy (WBRT), radiosurgery (RS; gamma knife, linear accelerator \[LINAC\], or equivalent) or a combination as deemed appropriate by the treating physician. Patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to day 1 will be excluded

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT03608631), the sponsor (M.D. Anderson Cancer Center), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT03608631?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
