Details and patient eligibility

About

The purpose of this study is to evaluate the efficacy and safety of NIS793 in combination with gemcitabine/nab-paclitaxel versus gemcitabine/nab-paclitaxel and placebo in first-line metastatic pancreatic ductal adenocarcinoma (mPDAC).

This study aims to explore whether blockade of Transforming Growth Factor β (TGFβ) in combination with gemcitabine/nab-paclitaxel can reduce fibrosis in PDAC, restore chemo-sensitivity and ultimately lead to improvements in overall survival (OS) and other clinically relevant outcomes.

Full description

This is a randomized, double-blind, multicenter two-arm, phase III study that has two parts:

• Safety run-in part: An open-label safety run-in part will be conducted to confirm recommended phase 3 dose (RP3D) of NIS793 in combination with gemcitabine and nab-paclitaxel. Up to approximately 10 participants will be enrolled at each dose level to achieve at least 6 evaluable participants; however, if the starting dose is not recommended and a lower dose level is tested, 10 additional participants will be enrolled. The decision to open the randomized part will be based on dose confirmation and available safety, relevant PK, and other relevant data from run-in part
• Randomized part: Enrolled participants will be randomized to the two treatment arms.

The study treatment will be administered as a 28-day treatment cycle. Participants will be treated until unacceptable toxicity, disease progression per RECIST 1.1, withdrawal of consent or any other condition of treatment discontinuation specified in the protocol.

Note: As of 07-Jul-2023, treatment with NIS793/placebo was stopped. The trial was unblinded and study participants were allowed to continue with standard of care (SoC) chemotherapy (gemcitabine+ nab-paclitaxel) per investigator assessment.

Inclusion and exclusion criteria

Inclusion Criteria:

• Applicable for both Safety run-in and Randomized part

  • Participants aged ≥18 years with histologically or cytologically confirmed (based on local assessment and per local guidelines) mPDAC eligible for treatment in the first line setting and not amenable for potentially curative surgery
  • Presence of at least one measurable lesion assessed by Computerized Tomography (CT) and/or Magnetic Resonance Imaging (MRI) according to RECIST 1.1
  • Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1
  • Adequate organ function (assessed by central laboratory for eligibility)
  • Participants must have recovered from treatment-related toxicities of prior anticancer therapies to grade ≤ 1 (CTCAE v 5.0) at time of screening, except alopecia.

Main Exclusion Criteria:

• Applicable for both Safety run-in and Randomized part

  • Previous systemic anti-cancer treatment for metastatic PDAC
  • Pancreatic neuroendocrine (islet) or acinar tumors
  • Participants with known status of microsatellite instability-high (MSI-H) or mismatch repair-deficient pancreatic cancer (if status is not already available, testing is not required at screening).
  • Participant has not recovered from a major surgery performed prior to start of study treatment or has had a major surgery within 4 weeks prior to start of study treatment.
  • Radiation therapy or brain radiotherapy ≤ 4 weeks prior to start of study treatment (palliative radiotherapy to bone lesions allowed > 2 weeks prior to start of study treatment).
  • Impaired cardiac function or clinically significant cardio-vascular disease
  • Use of hematopoietic growth factors or transfusion support ≤ 2 weeks prior to start of study treatment.
  • Participant has conditions that are considered to have a high risk of clinically significant gastrointestinal tract bleeding or any other condition associated with or history of significant bleeding.
  • Serious non-healing wounds.
  • Pregnant or breast-feeding women
  • Women of childbearing potential, unless willing to use highly effective contraception methods during treatment and after stopping study treatments as indicated
  • Pre-existing peripheral neuropathy > grade 1 (CTCAE v5.0)
