About this study
Official title: Multicenter, Randomized, Parallel Group, Phase 2 to Establish the Efficacy and Safety of Combinations of CBP501, Cisplatin, and Nivolumab for ≥3rd Line Treatment of Patients With Exocrine Pancreatic Cancer and WBC <10,000/mm3 at Screening
Multicenter, randomized, open-label, parallel group phase 2 study to assess the efficacy and tolerance of four combinations of CBP501, cisplatin, and nivolumab administered once every 21 days to patients with stage IV exocrine pancreatic cancer and WBC < 10,000/mm3 at screening.
Read the detailed description
Multicenter, randomized, open-label, parallel group phase 2 study to assess the efficacy and tolerance of four combinations of CBP501, cisplatin, and nivolumab administered once every 21 days to patients with stage IV exocrine pancreatic cancer and WBC < 10,000/mm3 at screening. Patients will be randomized 1:1:1:1 to the following four treatment groups, with randomization stratified by ECOG PS (0 vs 1) and liver metastasis (present vs absent):
- CBP501 25 mg/m2 + cisplatin 60 mg/m2 + nivolumab 240 mg
- CBP501 16 mg/m2 + cisplatin 60 mg/m2 + nivolumab 240 mg
- CBP501 25 mg/m2 + cisplatin 60 mg/m2
- Cisplatin 60 mg/m2 + nivolumab 240 mg No more than 4 cycles of combination therapy may be administered but patients who remain progression-free after 4 cycles may receive up to 6 additional cycle of single-agent nivolumab.
A Fleming two-stage design will be used. For each study arm, the null hypothesis that the true percentage of patients progression-free at 3 months is 10% will be tested against a one-sided alternative. In the first stage, 9 patients will be accrued to each study arm. In the first stage, if there are 1 or fewer patient progression-free at 3 months the study will be stopped for futility and if there are 4 or more patients progression-free at 3 months the study will stopped and the null hypothesis rejected. Otherwise, 14 additional patients will be accrued to the study arm for a total of 23. The null hypothesis will be rejected if 6 or more of 23 patients are progression-free at 3 months. This design yields a type I error rate of 2.5% and power of 80% when the true percentage of patients progression-free at 3 months is 35%.

What is being measured
The primary outcome is the main question the study is designed to answer.
Three-month progression free survival rate (3M PFSR)
Tumor assessment by RECIST v.1.1 criteria will be performed at screening, every 8 weeks starting after Cycle 1 Day 1, at the End-of-Treatment visit, and every 3 months after the End-of-Treatment visit until disease progression is observed.
Measured: 3 months after treatment
Secondary outcomes (6)
Safety profiles of the combinations of CBP501, cisplatin, and nivolumab administered once every 21 days
Safety will be assessed throughout the study through clinical and laboratory safety evaluations. These include physical examinations, vital sign measurements, 12-lead ECGs, laboratory safety tests (hematology, INR, serum chemistry, serum cardiac markers), and clinical adverse experience monitoring. Adverse events will be evaluated at each visit throughout the study and assigned a grade, defined by NCI-CTCAE version 5.0 criteria, and relationship to study treatment (unrelated, related).
Measured: One year
Progression-free survival (PFS)
Tumor assessment by RECIST v.1.1 criteria will be performed at screening, every 8 weeks starting after Cycle 1 Day 1, at the End-of-Treatment visit, and every 3 months after the End-of-Treatment visit until disease progression is observed.
Measured: one year
Confirmed and timepoint objective response rates (cORR/ORR)
Tumor assessment by RECIST v.1.1 criteria will be performed at screening, every 8 weeks starting after Cycle 1 Day 1, at the End-of-Treatment visit, and every 3 months after the End-of-Treatment visit until disease progression is observed.
Measured: one year
Duration of responses (DoR)
Tumor assessment by RECIST v.1.1 criteria will be performed at screening, every 8 weeks starting after Cycle 1 Day 1, at the End-of-Treatment visit, and every 3 months after the End-of-Treatment visit until disease progression is observed.
Measured: one year
disease control rate (DCR: CR + PR + SD ≥12 weeks)
Tumor assessment by RECIST v.1.1 criteria will be performed at screening, every 8 weeks starting after Cycle 1 Day 1, at the End-of-Treatment visit, and every 3 months after the End-of-Treatment visit until disease progression is observed.
Measured: one year
Overall survival (OS)
Tumor assessment by RECIST v.1.1 criteria will be performed at screening, every 8 weeks starting after Cycle 1 Day 1, at the End-of-Treatment visit, and every 3 months after the End-of-Treatment visit until disease progression is observed.
Measured: one year

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing CBP501 (16), CBP501 (25) and Cisplatin in people with Pancreatic Cancer Stage IV, run by CanBas Co. Ltd. at 20 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 24 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 20 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Three-month progression free survival rate (3M PFSR) (time frame: 3 months after treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04953962, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Aug 2023; AzTrials last refreshed its copy on 8 Nov 2026.
