Brief summary
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.
Detailed 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety run-in part: Percentage of participants with dose limiting toxicities (DLTs) during the first cycle (4 weeks) of treatment. | Up to 4 weeks | Percentage of participants with DLTs during the first cycle of treatment in the safety run-in part. A DLT is defined as an adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness or concomitant medication that occurs within the first cycle of treatment with NIS793 in combination with gemcitabine and nab-paclitaxel |
| Randomized part: Overall survival (OS) | From randomization up to death, assessed up to approximately 19 months | OS is defined as the time from date of randomization to date of death due to any cause. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Dose intensity of NIS793 in combination with gemcitabine and nab-paclitaxel | Up to approximately 19 months | Tolerability measured by the dose intensity of NIS793. Dose intensity will be computed as the ratio of actual cumulative dose received and actual duration of exposure |
| Progression-free survival (PFS) by investigator assessment per RECIST 1.1 | From enrollment (run-in part) or randomization (randomized part) up to disease progression or death, assessed up to approximately 19 months | PFS defined as the time from the date of enrollment (run-in part) or randomization (randomized part) to the date of the first documented progression based on investigator assessment and according to RECIST 1.1 or death due to any cause. |
| Overall response rate (ORR) by investigator assessment per RECIST 1.1 | Up to approximately 19 months | ORR is defined as the proportion of participants with best overall response (BOR) of complete response (CR) or partial response (PR), as per investigator assessment and according to RECIST 1.1 |
| Disease control rate (DCR) by investigator assessment per RECIST 1.1 | Up to approximately 19 months | DCR is the proportion of participants with BOR of CR or PR or stable disease (SD) as per investigator assessment and according to RECIST 1.1 |
| Time to response (TTR) by investigator assessment per RECIST 1.1 | From enrollment (run-in part) or randomization (randomized part) up to first documented response, assessed up to approximately 19 months | TTR is defined as the duration of time between the date of enrollment (run-in part) or randomization (randomized part) and the date of first documented response of either CR or PR. |
