About

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

Full 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.

Enrollment: 30 patients

Inclusion criteria

• Patients with histologically confirmed metastatic pancreatic ductal carcinoma
• One or more metastatic lesions measurable on MRI, PET/CT, or dedicated CT scan according to RECIST v1.1.
• Eligible for treatment with nabpaclitaxel and gemcitabine
• Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
• Life expectancy of at least 3 months
• Adequate archival tissue from prior biopsy for biomarker evaluation or willingness to undergo biopsy before treatment starts
• The patient is capable of understanding and complying with the protocol and the subject or, when applicable, the subject's legally acceptable representative has signed the informed consent
• A negative serum pregnancy test (if a premenopausal female patient)
• Acceptable liver function: Bilirubin ≥ 1.5 times upper limit of normal; AST (SGOT) < 10 times upper limit of normal, ALT (SGPT) and Alkaline phosphatase 2.5 times upper limit of normal (if liver metastases are present, then ≤ 5 x ULN is allowed).
• Acceptable renal function: Serum creatinine within normal limits; calculated creatinine clearance ≥ 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal by the Cockroft-Gault equation.
• Acceptable hematologic status: Granulocyte ≥ 1500 cells/mm3; Platelet count ≥ 100,000 plt/mm3; Hemoglobin ≥ 9 g/dL.
• Urinalysis: No clinically significant abnormalities.
• Acceptable coagulation status: PT within normal limits; PTT within normal limits.
• For men and women of child-producing potential, the use of effective contraceptive methods during the study.

Exclusion criteria

• Prior chemotherapy or any other investigational agents for the treatment of pancreatic cancer.
• Concurrent use of any other anti-cancer therapy, including chemotherapy, targeted therapy, immunotherapy, or biological agents.
• Participants with known brain metastases.
• New York Heart Association Class III or IV, cardiac disease, myocardial infarction within the past 6 months, unstable arrhythmia, or evidence of ischemia on ECG.
• Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy.
• Pregnant or nursing women. Women of child-bearing potential and men must agree to use adequate contraception.
• Unwillingness or inability to comply with procedures required in this protocol.
• Known infection with HIV, hepatitis B, or hepatitis C.
• Serious nonmalignant disease (e.g., hydronephrosis, liver failure, or other conditions per physician judgement) that could compromise protocol objectives in the opinion of the investigator and/or the sponsor.

Masking: None (Open label)

---

30 participants in 2 patient groups

Part A (Dose Escalation)

Experimental group

Description:

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.

Treatment:

Drug: Gemcitabine

Drug: Nab-paclitaxel

Drug: CEND-1

Part B (Expansion)

Experimental group

Description:

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.

Treatment:

Drug: Gemcitabine

Drug: Nab-paclitaxel

Drug: CEND-1
