入选标准

  • 1. Subject has one of the following solid tumors which has progressed on or following at least one systemic therapy regimen administered for advanced or metastatic disease or for which
  • no approved therapy exists:
  • NTRK-fusion-positive, locally advanced (i.e., not amenable to surgical resection) or metastatic solid tumor
  • NTRK-gene amplified, locally advanced or metastatic solid tumor (Phase 1 only)
  • EWSR1-WT1-positive DSRCTs (Phase 1 only)
  • Note: Subjects with any grade of malignant glioma previously treated with systemic therapy are eligible. Subject’s prior treatment should include all approved regimens that have demonstrated a
  • survival advantage for the subject’s disease, stage, and line of therapy.
  • 2. Phase 1
  • Subjects with NTRK-fusion-positive solid tumors other than primary brain tumors (non-brain primary tumors) must have previously received treatment with a TRK
  • inhibitor, unless the subject does not have access to TRK-inhibitor therapy (e.g., no TRK inhibitor is marketed and available to the subject in the subject’s country) or the subject
  • has declined treatment with available marketed TRK inhibitors.
  • Subjects with NTRK-gene-amplified solid tumors, primary brain tumors or EWSR1-WT1- positive DSRCTs may have received prior treatment with a TRK inhibitor but this is not
  • 3. Phase 2
  • Has measurable disease by RECIST v1.1 for subjects with non-brain primary tumors or RANO criteria for subjects with primary brain tumors.
  • Subjects with non-brain primary tumors must have previously received treatment with a TRK inhibitor and must have a documented on-target resistance mutation(s) (e.g., solvent
  • front, gatekeeper or xDFG mutation) as the mechanism of resistance to their prior
  • TRK-inhibitor treatment based on a tumor biopsy obtained following their most recent systemic therapy. Archival tissue from a prior biopsy taken after the subject completed
  • TRK-inhibitor treatment but prior to additional systemic therapy may be used to meet this eligibility criterion with Medical Monitor approval.
  • Subjects with primary brain tumors may have received prior treatment with a TRK inhibitor but this is not required. For these subjects who have previously been treated
  • with a TRK inhibitor, a tumor biopsy any time following TRK-inhibitor treatment is encouraged, and if analyzed for resistance mechanisms, must demonstrate an on-target
  • resistance mutation (e.g. solvent front, gatekeeper or xDFG mutation) as the mechanism of resistance to their prior TRK-inhibitor treatment. However, biopsies of brain tumors
  • are not required for eligibility.
  • Note: Subjects with NTRK-gene amplified tumors or EWSR1-WT1-positive DSRCTs are not eligible in Phase 2.
  • 4. Subjects with brain tumors and brain metastasis must be neurologically stable. Subjects with ongoing neurologic signs, symptoms, or a history of seizures due to their intracranial tumor or
  • on antiseizure medication must be approved for enrollment by the Medical Monitor.
  • 5. Age = 18 years at the time of signing the informed consent form (ICF)
  • 6. Has provided written informed consent
  • 7. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score of 0 or 1. Subjects with PS = 2 may be approved by the Medical Monitor.
  • 8. Acceptable liver, renal, hematologic, and coagulation function
  • Bilirubin = 1.5x ULN
  • AST, ALT = 3.0x ULN
  • Serum creatinine = 1.5x ULN and/or an estimated creatinine clearance of = 45 ml/min based on the Cockcroft-Gault formula
  • Absolute neutrophil count = 1000/mm3

排除标准

  • 1. Cytotoxic chemotherapy, biologic agent, investigational agent, or radiation therapy = 3 weeks
  • prior to the first dose of PBI-200 (6 weeks for nitrosoureas). The interval may be reduced to
  • 2 weeks for bone-only radiation therapy or investigational agents not expected to be
  • associated with AEs after 2 weeks of last administration, with Medical Monitor approval.
  • a. Subjects with either primary brain tumors or brain metastasis must have completed brain
  • radiation therapy 12 weeks prior to the brain MRI obtained within 4 weeks of the first
  • dose of PBI-200. The Medical Monitor may approve an interval of less than 12 weeks if
  • there is reasonable certainty of radiographic disease progression (e.g., new disease
  • outside the radiation therapy field following completion of the radiation therapy) or
  • histopathologic documentation of unequivocal disease progression
  • 2. Small-molecule kinase inhibitors or hormonal agents = 14 days and within 5 half-lives prior
  • to the first dose of PBI-200
  • 3. For subjects enrolled in Phase 2: Treatment with more than one prior TRK inhibitor.
  • Note: Subjects enrolled in the Phase 1 part of the study may have received more than one
  • TRK inhibitor.
  • 4. Clinically significant AEs that have not returned to baseline or = Grade 1 based on NCI
  • CTCAE v5.0 unless approved by the Medical Monitor
  • 5. Subjects with leptomeningeal disease (primary or metastatic) unless approved by the Medical
  • 6. Major surgery = 6 weeks or minor surgery = 14 days prior to the first dose of PBI-200
  • 7. Clinically significant intercurrent disease including but not limited to:
  • New York Heart Association Class III or IV heart failure
  • Myocardial infarction or stroke = 26 weeks prior to the first dose of PBI-200
  • Unstable angina within = 13 weeks prior to the first dose of PBI-200 unless the
  • underlying disease has been corrected by procedural intervention e.g., stent, bypass
  • Severe aortic stenosis
  • Uncontrolled arrhythmia. Medical Monitor approval of subjects with an arrhythmia is
  • Congenital long QT syndrome. Medical Monitor approval is required
  • QTc > 470 milliseconds by Fredericia criteria (QTcF) based on the average of 3 ECGs
  • taken approximately 1 minute apart and all within 10 minutes of each other. The subject
  • should be reclining for 5 minutes prior to ECGs. Local readings may be used for this
  • inclusion criterion.
  • Clinically significant active infection requiring systemic antibiotic, antiviral or antifungal
  • medication. Subjects must be medically stable, afebrile, and not taking antimicrobial
  • treatment for = 3 days prior to the first dose of PBI-200
  • 8. Subjects taking sensitive substrates of CYP2B6, CYP2C8, CYP2C9 and CYP3A unless the
  • subject can safely discontinue these medications or change to comparable medications that
  • are not sensitive substrates of these CYPs
  • 9. Subjects that are taking strong CYP3A inhibitors or inducers unless the subject can safely
  • discontinue these medications or change to comparable medications that are not strong
  • inhibitors or inducers of CYP3A at least 5 half-lives or 7 days prior to the first dose of
  • 10. Human immunodeficiency virus (HIV) infection
  • 11. Active hepatitis B or C infection
  • 12. Has a history of another malignancy, unless the subject has been treated with curative intent
  • for this malignancy. Medical Monitor approval for enrollment is required for subjects with a
  • history of another malignancy. Study subjects with early-stage prostate cancer on active
  • surveillance may be enrolled
