A study to assess the biochemical and immunomodulatory effects of BXCL701 in pancreatic cancer.

Detailed Description

      This is a Phase 0 or "window of opportunity" study where paired specimen analysis, taken
      before and after drug exposure, will permit the evaluation of target modulation and
      assessment of immune effector cell infiltration into the tumor and the generation of relevant
      immune cytokines.

      In this study, BXCL701 will be administered at a dose of 0.3 mg, twice daily for a total
      daily dose of 0.6mg (the previously defined maximum tolerated dose [MTD] of the drug), to all
      patients for a short period of 14 days. This study is designed to assess the biochemical and
      immunomodulatory effects of BXCL701 in pancreatic cancer.

Trial Arms

Single ArmExperimentalBXCL701 will be administered for one week at a dose of 0.2 mg, twice daily (BID). If BXCL701 is well-tolerated after the first week of treatment, the dose will be increased to 0.3mg BID for a total daily dose of 0.6mg to all patients for the second week of treatment.

Eligibility Criteria

        Inclusion Criteria:

          1. Has untreated (eg, no prior investigational therapies, chemotherapy, or radiation
             therapy), locally advanced or metastatic adenocarcinoma of the head, neck, uncinate
             process, or tail of the pancreas with a local or metastatic lesion that is amenable to
             biopsy before and after treatment. (Whenever possible, the before and after treatment
             biopsies should be from the same lesion.)

             pretreatment biopsy may not be needed if tissue is available from a biopsy conducted
             within 28 days prior to screening that is adequate for the study assessments.)

          3. Has Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.

          4. Is 18 to 75 years of age, inclusive

          5. Has adequate organ function within 28 days of treatment initiation

          6. For participants with exposure to prior agents associated with decreased left
             ventricular ejection fraction (LVEF) (e.g. anthracyclines), or if clinically
             warranted, a documented LVEF > 45% using a standard echocardiogram (ECHO) or
             multigated acquisition (MUGA) scan test at Screening or within 60 days prior to Cycle
             1 Day 1. ECHO or MUGA testing for other participants without relevant medical history
             or clinical symptoms can be performed if feasible.

          7. Has oxygen saturation ≥ 92% on room air.

          8. Is able to take an oral medication.

          9. Has signed an Informed Consent Form (ICF) prior to the initiation of any
             study-specific procedures or treatment.

         10. Is willing and able to adhere to the study visit schedule and other protocol

         11. Women of childbearing potential (WOCBP) must have a negative pregnancy test at
             baseline. A woman must be menopausal for at least 12 months before she is considered
             not to be of reproductive potential.

             contraceptive method during participation in this study and for 6 months following the

             disorder that is severe enough to hinder the ability of the patient to provide
