Study of SBP-101 Combined With Nab-Paclitaxel and Gemcitabine in Pancreatic Cancer
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This is an open-label phase 1A/1B study to assess the safety, tolerability and pharmacokinetics of SBP-101 when combined with nab-paclitaxel and gemcitabine in subjects with previously untreated metastatic pancreatic ductal adenocarcinoma and to identify a recommended phase 2 dose. The study will also assess preliminary efficacy of the 3-drug treatment combination.

The study will be conducted in two phases: dose escalation and expansion. Up to three dose levels of SBP-101 will be assessed in up to 18 subjects during dose escalation. The expansion phase of the study will consist of 10 additional subjects who will receive the recommended dose of SBP-101 combined with nab-paclitaxel and gemcitabine.

Ages Eligible for Study:
18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Histologically or cytologically confirmed metastatic pancreatic ductal adenocarcinoma. Patients with pancreatic acinar cell carcinoma may also be included.
Is previously untreated for metastatic pancreatic ductal adenocarcinoma, was diagnosed within the past 3 months, and is expected to receive standard treatment with gemcitabine and nab-paclitaxel.
Measurable disease on CT or MRI scan by RECIST v 1.1 criteria.
ECOG Performance Status 0 or 1.
Adult, age ≥ 18 years, male or female.
Females of child-bearing potential must have a negative serum pregnancy test within 14 days prior to start of study treatment and must use an adequate method of contraception during the study. All sexually active males must also use an adequate method of contraception during the study. Female subjects will be considered to be of childbearing potential unless they are postmenopausal (at least 12 months of consecutive amenorrhea, without other known or suspected cause) and over 55 years old or have been sterilized surgically (i.e., bilateral tubal ligation, hysterectomy or bilateral oophorectomy, all with surgery at least one month before dosing).
Adequate bone marrow, hepatic, renal and coagulation function as defined by the following:
Absolute neutrophil count ≥1.5 x 109/L
Hemoglobin ≥9.0 g/dL (90 g/L)
Platelets ≥100 x 109/L
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 x upper limit of normal (ULN) (if no hepatic metastases). If hepatic tumor involvement, AST and ALT ≤5 x ULN.
Bilirubin ≤1.5 x ULN
Prothrombin time (PT) / international normalized ratio (INR) ≤1.5 x ULN if not on anti-coagulants
Calculated creatinine clearance >50 mL/min using the Cockcroft and Gault equation
QTc interval ≤ 470 msec at Baseline.
Life expectancy ≥ 3 months.
Willing and able to provide written informed consent: voluntary agreement to participate in the study following disclosure of risks and procedures required, including possibility of onset of exocrine pancreatic insufficiency with subsequent requirement for life-long pancreatic enzyme replacement.
Evidence of severe or uncontrolled systemic disease or any concurrent condition that, in the opinion of the Investigator or Medical Monitor, makes it undesirable for the subject to participate in the study or that would jeopardize compliance with the protocol. Subjects with pre-existing well-controlled diabetes are not excluded.
Medical or psychiatric conditions that compromise the subject's ability to give informed consent or to complete the protocol or a history of non-compliance
Presence of islet-cell or pancreatic neuroendocrine tumor or mixed adenocarcinoma-neuroendocrine carcinoma
Have symptomatic central nervous system (CNS) malignancy or metastasis. Screening of asymptomatic subjects without history of CNS metastases is not required.

Maldigestion/malabsorption syndrome pre-dating the diagnosis of pancreatic cancer.
Pregnant or lactating
Major surgery within 4 weeks of the start of study treatment, without complete recovery
Known hypersensitivity to any component of study treatments
Participation in any other clinical investigation within 4 weeks of receiving the first dose of study drug
Subjects taking metformin. Diabetics on treatment with metformin, or any other derivative thereof, must discontinue it while on study. (Other diabetic medications are allowed.)
