About

This study is being done to evaluate the safety and efficacy of adding NIS793 to standard of care FOLFIRINOX treatment for pancreatic cancer.

The names of the study interventions involved in this study are:

• NIS793
• FOLFIRINOX (Folinic acid/Leucovorin, 5-Fluorouracil, Irinotecan, and Oxaliplatin)

Other interventions may include:

• Chemoradiation Therapy
• Surgery

Full description

This is a randomized phase 2 study evaluating the efficacy of NIS793, a TGF-beta inhibitor, when added to a standard chemotherapy program of modified FOLFIRINOX for people with previously-untreated, resectable or borderline resectable pancreatic adenocarcinoma.

The U.S. Food and Drug Administration (FDA) has not approved NIS793 as a treatment for any disease. NIS793 works by blocking a molecule called TGF-beta. TGFbeta has been shown to promote the growth of pancreatic cancer and this study is examining if the addition of a TGF-beta blocking drug will allow the chemotherapy to work better against the cancer.

The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.

Participants will be randomized into two groups of:

• Arm A will receive standard chemotherapy, mFOLFIRINOX, in combination with NIS793.
• Arm B will receive standard chemotherapy, mFOLFIRINOX.

Based on study team determination, some participants may be offered chemoradiation following completion of chemotherapy and/or surgery following either completion of chemotherapy or chemoradiation.

Study treatment is expected to last up to 16 weeks unless disease symptom worsens .

It is expected that about 45 people will take part in this research study.

Enrollment: 8 patients

Sex: All

Ages: 18+ years old

  • Vessel: Celiac axis, Resectable: No extension, Borderline resectable: Interface between tumor and vessel measuring less than 180º of the circumference of the vessel wall, Locally advanced (Not Eligible): Encased and no technical option for reconstruction usually because of extension to the celiac axis/ splenic/left gastric junction or the celiac origin

  • Vessel: Common hepatic artery, Resectable: No extension, Borderline resectable: Reconstructable§, short-segment interface between tumor and vessel of any degree, Locally advanced (Not Eligible): Encased and no technical option for reconstruction usually because of extension to the celiac axis/ splenic/left gastric junction or the celiac origin Vessel: SMV/PV, Resectable: Patent, Borderline resectable:SMV/PV Patent Interface between tumor and vessel measuring 180º or greater of the circumference of the vessel wall, and/or reconstructable§ occlusion Occluded and no technical option for reconstruction, Locally advanced (Not Eligible): Occluded and no technical option for reconstruction

    • Referenced from: Varadhachary et al., 2006(6) and Katz et al, 2013 (8). SMA, superior mesenteric artery; SMV/PV, superior mesenteric vein/portal vein.
    • Normal vein or artery proximal and distal to the site of suggested tumor-vessel involvement suitable for vascular reconstruction

• In subjects requiring biliary decompression, biliary stent or drainage using percutaneous transhepatic cholangiogram (PTC) are allowed.

• Participants must be ≥18 years of age at the time of enrollment.

• Participants must have an ECOG performance status 0-1 (see Appendix A).

• Participants must have adequate organ and marrow function as defined as:

  • Absolute neutrophil count ≥1,500/mcL
  • Platelets ≥100,000/mcL
  • Total bilirubin ≤1.5 × institutional upper limit of normal
  • AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal
  • Creatinine ≤1.5 × institutional upper limit of normal OR
  • Creatinine clearance ≥60 mL/min/1.73 m2 for participants with creatinine levels above 1.5 × upper limit of normal. Creatinine clearance can be calculated per institutional standard.

• Female subjects of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile or abstain from heterosexual activity for the course of the study through 9 months after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.

• Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 6 months after the last dose of study therapy.

• Ability to understand and the willingness to sign a written informed consent document.

Exclusion criteria
