SMAD4 Tailored Neoadjuvant Therapy for the Treatment of Resectable and Borderline Resectable Pancreatic Ductal Adenocarcinoma, SMART-PANC Trial

31 luglio 2026 aggiornato da: Northwestern University

SMART-PANC: SMAD4 Tailored Neoadjuvant Therapy for Pancreatic Cancer, A Phase ll Non-Randomized, Single Center Pilot Study

This phase II trial tests the impact of using SMAD4-mutant status to personalize chemotherapy in treating patients with pancreatic ductal adenocarcinoma (PDAC) that can be removed by surgery (resectable) or that may be between resectable and unresectable (borderline resectable) before undergoing surgery (neoadjuvant). PDAC is one of the most aggressive and fastest growing tumors. SMAD4, a tumor suppressor gene, acts like a brake on cell growth and helps to prevent tumor cells from growing. However, losing it makes the tumor more aggressive and often resistant to standard of care (SOC) treatments regimens, such as gemcitabine with nab-paclitaxel and fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX). Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic (DNA) and may kill tumor cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Nab-paclitaxel is an albumin-stabilized nanoparticle formulation of paclitaxel which may have fewer side effects and work better than other forms of paclitaxel. Fluorouracil, a type of antimetabolite, stops cells from making DNA and it may kill tumor cells. Leucovorin is a form of folic acid. It is a type of chemoprotective agent and a type of chemosensitizing agent. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill tumor cells. Instead of a one-sized fits all treatment approach with SOC therapies, matching therapy based on SMAD4 mutation status may use this specific genetic weakness against the tumor. This approach to neoadjuvant therapy may dramatically alter the path of treatment and improve outcomes, including complete resection rates, in patients with resectable or borderline resectable PDAC.

Descrizione dettagliata

PRIMARY OBJECTIVE:

I. To determine the R0/R1 surgical resection rate among patients with SMAD4-mutant pancreatic cancer treated with gemcitabine/nab-paclitaxel (Cohort A).

SECONDARY OBJECTIVES:

I. To estimate the trial participation rate among patients approached for enrollment, defined as the proportion of patients who consent and enroll among those approached, with a target participation rate of ≥ 70%, and to monitor this rate continuously during accrual.

II. To estimate the R0/R1 surgical resection rate among SMAD4 wild-type patients treated with physician choice chemotherapy (Cohort B).

III. To determine pathologic response rates, among the subset of patients who reach surgical resection.

IV. To determine the progression free survival (PFS). V. To determine the overall survival (OS).

EXPLORATORY OBJECTIVES:

I. To estimate the proportion of R0 resections among patients with SMAD4-mutant pancreatic cancer treated with gemcitabine/nab-paclitaxel (Cohort A) who undergo surgical resection (R0/R1).

II. To estimate the proportion of R0 resections among patients with SMAD4 wild-type patients treated with physician choice chemotherapy (Cohort B) who undergo surgical resection (R0/R1).

III. To compare R0/R1 resection rates between Cohort A (SMAD4-mutant, gemcitabine/nab-paclitaxel) and Cohort B (SMAD4 wild-type, physician choice) in a descriptive, exploratory manner; the study is not powered for formal non-inferiority or superiority testing of this comparison.

IV. To determine the preoperative/neoadjuvant ca19-9 dynamics in both cohorts. V. To determine the preoperative/neoadjuvant circulating tumor DNA (ctDNA) dynamics in both cohorts.

VI. To assess reason for failure to reach surgical resection, categorized by clinical deterioration, patient withdrawal/refusal of surgery, metastatic progression, or local disease progression precluding surgery.

OUTLINE: Patients with SMAD4 alterations are assigned to Cohort A and patients without SMAD4 mutations are assigned to Cohort B.

COHORT A: Patients receive gemcitabine and nab-paclitaxel with or without radiation therapy per SOC. Treatment continues for 8 weeks in the absence of disease progression or unacceptable toxicity. After 8 week restaging, patients may continue to receive treatment for up to 16 or 24 weeks at the discretion of the multidisciplinary tumor board. Starting 21 days after last dose of chemotherapy, patients undergo surgical resection. Additionally, patients undergo blood sample collection and computed tomography (CT) or magnetic resonance imaging (MRI) as clinically indicated throughout the study.

COHORT B: Patients receive either physicians choice of either fluorouracil, leucovorin, irinotecan, and oxaliplatin or gemcitabine and nab-paclitaxel with or without radiation therapy per SOC. Treatment continues for 8 weeks in the absence of disease progression or unacceptable toxicity. After 8 week restaging, patients may continue to receive treatment for up to 16 or 24 weeks at the discretion of the multidisciplinary tumor board. Starting 21 days after last dose of chemotherapy, patients undergo surgical resection. Additionally, patients undergo blood sample collection and CT or MRI as clinically indicated throughout the study.

After completion of study treatment, patients are followed up at 30 days from surgical resection then every 3 months for up to 2 years from study enrollment.

Misura Descrizione
Lasso di tempo
Trial participation rate
Lasso di tempo: Up to 2 years
Will be defined as the proportion of patients who consent and enroll among all patients who are approached and eligible for trial participation. Will be summarized using proportions with exact confidence intervals. Feasibility monitoring will occur on an ongoing basis during accrual (e.g. monthly or after every 20 approached eligible patients, whichever occurs first) using cumulative participation rate.
Up to 2 years
Proportion of patients who achieve R0/R1 surgical resection rate (Cohort B)

Among participants who undergo R0/R1 surgical resection, the proportion achieving R0 resection will be summarized.
Up to 30 days after surgical resection
Pathologic response rates
Lasso di tempo: Up to 30 days after surgical resection
Pathology reports will be reviewed to determine the College of American Pathologists (CAP) tumor regression score, categorized from 0 (complete response) to 3 (poor or no response). CAP tumor regression scores will be summarized descriptively as frequencies and percentages across categories. The distribution of reasons for failure to reach surgical resection will be summarized descriptively using frequencies and percentages. These summaries may be further stratified by baseline resectability status and SMAD4 mutation status to provide clinical context and inform future trial design.
Up to 30 days after surgical resection
Progression free survival (PFS)
Lasso di tempo: From enrollment to disease progression or clinical deterioration that precludes complete surgical resection, disease recurrence after surgery, or death from any cause, assessed up to 2 years
PFS will be analyzed using Kaplan-Meier methods. The median PFS and corresponding 95% confidence interval will be estimated.
From enrollment to disease progression or clinical deterioration that precludes complete surgical resection, disease recurrence after surgery, or death from any cause, assessed up to 2 years
Overall survival (OS)
Lasso di tempo: From enrollment to the date of any cause of death or to the date of last follow-up, assessed up to 2 years
OS will be analyzed using Kaplan-Meier methods. Median OS and corresponding 95% confidence intervals will be reported.
From enrollment to the date of any cause of death or to the date of last follow-up, assessed up to 2 years
