Brief Summary:
CEND-1, Gemicitabine and Nab-Paclitaxel for Pancreatic Ductal Adenocarcinoma

Condition or disease Intervention/treatment Phase
Pancreatic Cancer Pancreatic Ductal Adenocarcinoma Drug: CEND-1 Drug: Nab-paclitaxel Drug: Gemcitabine Phase 1

Detailed Description:

This is an open-label, multicenter, dose-escalation, safety, pharmacodynamic, pharmacokinetic study of CEND-1 in combination with nabpaclitaxel and gemcitabine administered weekly for three weeks followed by one week off over 28 days.

This protocol is designed to evaluate the safety, tolerability, and biologic activity of CEND-1 in patients with metastatic pancreatic ductal adenocarcinoma (PDAC) who are undergoing combination therapy with nabpaclitaxel and gemcitabine. CEND-1 is a tumor-penetrating peptide (scientifically also known as iRGD) that activates a drug transport mechanism specifically in tumors.

Study involves an initial dose escalation phase with four different CEND-1 dose levels, first as a monotherapy (during 1-week run-in), followed by combination therapy with nabpaclitaxel and gemcitabine (one 28-day treatment cycle). A subsequent expansion phase with approximately 28 subjects will assess the safety, tolerability and preliminary efficacy of the combination treatment using two different CEND-1 dose levels.

Arm Intervention/treatment
Experimental: Part A (Dose Escalation)
Safety of ascending dose levels of CEND-1 in combination with gemcitabine and nab-paclitaxel will be evaluated. Patients will receive an IV bolus of CEND-1 on Day 1 of the 1-week run-in period. This is followed by one treatment cycle (28 days) with the CEND-1 / nab-paclitaxel (125mg/m^2) / gemcitabine (1000mg/m^2) combination given on Days 1, 8, 15.
 Drug: CEND-1
CEND-1 will be provided as concentrate for solution to be administered via IV injection.
Other Name: iRGD

Drug: Nab-paclitaxel
Nab-paclitaxel will be provided as solution to be administered via IV infusion.
Other Name: Abraxane

Drug: Gemcitabine
Gemcitabine will be provided as solution to be administered via IV infusion.
Other Name: Gemzar
Experimental: Part B (Expansion)
Safety and early efficacy of CEND-1 in combination with nab-paclitaxel (125mg/m^2) and gemcitabine (1000mg/m^2) will be evaluated (dosing on Days 1, 8, 15 of the 28-day treatment cycle). Treatment cycles will be repeated every 4 weeks based on toxicity and response. Treatment may continue as long as there is perceived benefit or until disease progression.
 Drug: CEND-1

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Safe doses of CEND-1 when given alone or in combination with nabpaclitaxel and gemcitabine [ Time Frame: Escalation Phase: From Day 1 of the run-in until Day 28 of Cycle 1 (cycle length=28 days) ]
    Safety and toxicity profile of treatment regimen as measured by grade and frequency of adverse events, graded and documented according to the NCI CTCAE, version 5.0 guidelines

  2. Optimal Biological Dose (OBD) of CEND-1 when given in combination [ Time Frame: Expansion Phase: from baseline until treatment discontinuation and approximately 30 days after last dose (cycle length=28 days) ]
    OBD will be determined by evaluating biomarkers (such as the tumor marker CA19-9 Response Rate), the ECOG Performance Status and the Disease Control Rate


Secondary Outcome Measures :
  1. Pharmacokinetics of CEND-1 when given alone or in combination with nabpaclitaxel and gemcitabine [ Time Frame: Escalation phase: Predose, 3 minutes, 15 min, 30 min, 1 h, 4 h, 8 h postdose on Day 1 of the run-in and Day 1 of Cycle 1 ]
    Area Under the Concentration-Time Curve of CEND-1 Following Intravenous (IV) Administration

  2. Disease Control Rate (Complete Remission (CR) + Partial Remission (PR) + Stable Disease (SD)) associated with the administration of CEND-1 in combination with nabpaclitaxel and gemcitabine [ Time Frame: Expansion Phase: from baseline until treatment discontinuation and approximately 30 days after last dose (cycle length=28 days) ]
  3. Preliminary evidence of anti-tumor activity of CEND-1 when given in combination with nabpaclitaxel bound and gemcitabine by objective radiographic assessment according to RECIST 1.1 [ Time Frame: Expansion Phase: from baseline until treatment discontinuation and approximately 30 days after last dose (cycle length=28 days) ]

Other Outcome Measures:
  1. Immunohistochemical assessment of tumor biopsies for the expression of Neuropilin-1 in order to study if the response to CEND-1 therapy can be predicted based on the Neuropilin-1 expression level [ Time Frame: Screening Phase (Day -14 until Day -1) ]
    Analysis of paraffin-embedded tumor tissues (also potentially in liquid-nitrogen frozen tissue, if available) will be performed to characterize Neuropilin-1 expression by immunohistochemistry (IHC) and potentially other analysis techniques.
