RP72 Monotherapy and in Combination With Gemcitabine in Patients With Pancreatic Cancer
A Phase I Study to Evaluate the Safety and Efficacy of RP72 Monotherapy and in Combination With Gemcitabine in Patients With Pancreatic Cancer
This is a Phase I, multi center study to evaluate the safety and efficacy and determine the maximum tolerated dose (MTD) of RP72 as monotherapy and RP72 in combination with Gemcitabine in patients with pancreatic cancer.
The study has two arms:
Arm A: RP72 monotherapy
Arm B: RP72 in combination with Gemcitabine
Both treatment arms will follow a standard 3+3 design. Up to 48 adult patients with pancreatic cancer will be enrolled in this study.

Intervention / Treatment
Detailed Description
RP72 (Rise Prot-72) is a small molecular weight protein which directly binds to CXCR1 and CXCR2, which are the receptors of CXCL8 [Interleukin 8 (IL-8) or chemokine (C-X-C motif) ligand 8] and ELR-CXC chemokine. Therefore, RP72 can inhibit the binding of CXCL8 to its receptors CXCR1/2 and further block CXCL8-mediated signal transduction. Nonclinical studies have demonstrated that RP72 binds to the receptors of CXCL8 and blocks activation of CXCL8-mediated signaling transduction pathways, which decreases proliferation of susceptible tumor cells, especially the pancreatic cancer cells.
In this Phase I study, RP-72 will be used as monotherapy or in combination with gemcitabine in adult patients with pancreatic cancer. The study aims to to evaluate the safety and efficacy, and to determine the MTD and recommended Phase II dose of RP72 monotherapy and RP72 in combination with Gemcitabine in patients with Pancreatic Cancer.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Age ≥ 18 years (in certain territories, the minimum age requirement may be higher, e.g. age ≥ 20 years in Taiwan)
- Written informed consent
Patient must meet one of the following criteria based on:
Arm A (RP72 monotherapy): Histologically or cytologically confirmed locally advanced unresectable or metastatic pancreatic cancer that has progressed on (or intolerant of) one or more standard treatment regimen(s) or for which no effective therapy is available. Note: Prior exposure to gemcitabine as a single agent or in combination with other agents (as part of multi-agent chemotherapy regimen) is acceptable.
Or
Arm B (RP72 in combination with Gemcitabine): Histologically or cytologically confirmed locally advanced unresectable or metastatic pancreatic cancer that has progressed on (or intolerant of) one or more standard treatment regimen(s) and is expected (or currently receiving) standard treatment with gemcitabine.Note: Patients who have already started on gemcitabine need to have no evidence of disease progression at the time of screening in order to be eligible for the study.
Note: The definition of unresectability will follow the criteria of NCCN guidelines (Carroll et al. version 2.2016, PANC-B)

All male subjects and female subjects with child-bearing potential (between puberty and 2 years after menopause) should use appropriate contraception method(s) for at least 4 weeks after RP72 treatment shown below.
- Total abstinence (when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception).
- Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment.
