Study Details

Study Description

Brief Summary

The study is a randomized, double-blind, placebo-controlled, multicenter study of standard treatment with nab-paclitaxel and gemcitabine with or without SBP-101 in subjects previously untreated for metastatic PDA, including subjects who have received prior neoadjuvant or adjuvant treatment.

Detailed Description

The study will start with a 150-subject sentinel cohort and may continue with an expansion cohort depending on the results of a futility analysis to be performed when 104 required PFS events (death or disease progression, whichever comes first) are observed in the sentinel cohort.

    Outcome Measures

    Primary Outcome Measures

    1. Overall Survival (OS) [Randomization (Day 1) until death from any cause assessed up to 36 months]

      Compare OS between subjects who receive SBP-101 and those who do not receive SBP-101 (i.e., placebo) in combination with nab-paclitaxel and gemcitabine

    Secondary Outcome Measures

    1. Progression Free Survival (PFS) [Randomization (Day 1) until disease progression or death from any cause, whichever occurs first, assessed up to 36 months]

      Compare PFS between SBP-101 and placebo

    Other Outcome Measures

    1. Overall Objective Response (ORR) [Every 8 weeks during treatment for up to 36 months]

      Compare ORR between SBP-101 and placebo

    2. Disease Control Rate (DCR) [At least 16 weeks]

      Compare DCR between SBP-101 and placebo

    3. Duration of Response (DoR) [Onset of CR or PR until disease progression assessed up to 36 months]

      Compare DoR between SBP-101 and placebo

    4. Quality of Life (QOL) Questionnaires: EORTC QLC-C30 [Every 4 weeks during treatment for up to 36 months]

      Compare QOL changes in scores between SBP-101 and placebo

    5. Quality of Life (QOL) Questionnaires: QLQ-PAN26 [Every 4 weeks during treatment for up to 36 months]

      Compare QOL changes in scores between SBP-101 and placebo

    6. Number of Subjects with treatment-emergent adverse events as assessed by CTCAE v5.0 [Up to 36 months]

      Compare Safety and Tolerability of SBP-101 to placebo when administered in combination with nab-paclitaxel and gemcitabine

    7. Exploratory [Baseline to week 8 and maximum decrease overall assessed for up to 36 months]

      Compare effects of SBP-101 and placebo on blood levels of CA 19-9 and circulating tumor DNA (cT DNA)

Subjects who have had planned or prior surgery, such as a Whipple procedure, with or without neo-adjuvant/adjuvant chemotherapy may be included.

    • 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 are 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).

    Exclusion Criteria:
    • Subjects known to be BRCA (BReast CAncer gene) positive.

    • Subjects taking metformin. Diabetic subjects on treatment with metformin, or any other derivative thereof, must discontinue it while on study (other diabetic medications are allowed).

    • History of retinopathy or macular degeneration.

    • 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.

    • Symptomatic central nervous system (CNS) malignancy or metastasis. Screening of asymptomatic subjects without history of CNS metastases is not required.

    • Presence of interstitial lung disease, pulmonary fibrosis, or pulmonary hypersensitivity reaction.

    • Myocardial infarction within the last 12 months, severe/unstable angina, symptomatic congestive heart failure New York Heart Association (NYHA) class III or IV.

    • Pregnant or lactating.

    • Major surgery within 4 weeks of the start of study treatment, without complete recovery.
