QUILT-3.060: NANT Pancreatic Cancer Vaccine: Molecularly Informed Integrated Immunotherapy in Subjects With Pancreatic Cancer Who Have Progressed on or After Standard-of-care Therapy
Study Details
Study Description
Brief Summary
This is a phase 1b/2 study to evaluate the safety and efficacy of metronomic combination therapy in subjects with pancreatic cancer who have progressed on or after previous SoC chemotherapy. Phase 2 will be based on Simon's two-stage optimal design.

Phase 1/Phase 2 |
Detailed Description
Treatment will be administered in two phases, an induction and a maintenance phase, as described below. Subjects will continue induction treatment for up to 1 year. Treatment in the study will be discontinued if the subject experiences progressive disease (PD) or unacceptable toxicity (not corrected with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the subject's best interest to continue treatment. Those who have a complete response (CR) in the induction phase will enter the maintenance phase of the study. Subjects may remain on the maintenance phase of the study for up to 1 year. Treatment will continue in the maintenance phase until the subject experiences PD or unacceptable toxicity (not corrected with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the subject's best interest to continue treatment. The maximum time on study treatment, including both the induction and maintenance phases, is 2 years.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Age ≥ 18 years old.
-
Able to understand and provide a signed informed consent that fulfills the relevant IRB or Independent Ethics Committee (IEC) guidelines.
-
Histologically-confirmed pancreatic cancer with progression on or after SoC therapy.
-
ECOG performance status of 0 to 2.
-
Have at least 1 measurable lesion of ≥ 1.5 cm.
-
Must have a recent formalin-fixed, paraffin-embedded (FFPE) tumor biopsy specimen following the conclusion of the most recent anticancer treatment and be willing to release the specimen. If an historic specimen is not available, the subject must be willing to undergo a biopsy during the screening period, if considered safe by the Investigator. If safety concerns preclude collection of a biopsy during the screening period, a tumor biopsy specimen collected prior to the conclusion of the most recent anticancer treatment may be used.
-
Must be willing to provide blood samples prior to the start of treatment on this study.
-
Must be willing to provide a tumor biopsy specimen 8 weeks after the start of treatment, if considered safe by the Investigator.
-
Ability to attend required study visits and return for adequate follow-up, as required by this protocol.
-
Agreement to practice effective contraception for female subjects of child-bearing potential and non-sterile males. Female subjects of child-bearing potential must agree to use effective contraception for up to 1 year after completion of therapy, and non-sterile male subjects must agree to use a condom for up to 4 months after treatment. Effective contraception includes surgical sterilization (eg, vasectomy, tubal ligation), two forms of barrier methods (eg, condom, diaphragm) used with spermicide, intrauterine devices (IUDs), and abstinence.
