Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment

Further study details as provided by Sierra Oncology, Inc.:

Primary Outcome Measures:
  • Anti-tumor activity [ Time Frame: 4.5 months ]
    Anti-tumor activity will be assessed by Computerized Tomography (CT) scan, FDG-Positron Emission Tomography (PET) scan and biomarker analysis.

Secondary Outcome Measures:
  • Safety [ Time Frame: 4.5 months ]
    Safety will be assessed by physical examination, clinical laboratory tests (i.e., hematology, chemistry, urinalysis) and electrocardiogram.

Other Outcome Measures:
  • Pharmacokinetic Profile of PNT2258 [ Time Frame: 2 weeks ]
    The pharmacokinetic profile will be assessed by blood collection during Cycle 1.

  • Pharmacodynamic Effect of PNT2258 [ Time Frame: 4 weeks ]
    The pharmacodynamic effect of PNT2258 will be assessed by blood collection during Cycles 1 and 2.

Enrollment: 13
Study Start Date: November 2012
Study Completion Date: August 2016
Primary Completion Date: August 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PNT2258
PNT2258 120 mg/m2 will be administered as a 2-hour intravenous infusion on days 1-5 of a 21-day cycle. Treatment may continue (unless there is disease progression or the occurrence of unacceptable toxicity) for a total of 6 cycles of therapy.
Drug: PNT2258

Detailed Description:
PNT2258 will be administered at a dose of 120 mg/m2, as a 3-hour intravenous (IV) infusion on days 1-5 of a 21-day cycle. Treatment may continue (unless there is disease progression or the occurrence of unacceptable toxicity) for a total of 6 cycles of therapy.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Written informed consent must be obtained from the patient.
  2. Participants must be ≥18 years of age.
  3. Morphologically confirmed diagnosis of non-Hodgkin's lymphoma (NHL).
  4. At least a single measureable tumor mass (long axis > 1.5 cm).
  5. An FDG-PET positive baseline scan.

    a. A positive scan is defined per revised Cheson criteria as "focal or diffuse FDG uptake above background in a location incompatible with normal anatomy or physiology, without a specific standardized uptake value cutoff".

  6. Disease that has relapsed after administration of primary therapy that included:

    1. Rituximab and
    2. CHOP, EPOCH, bendamustine or similar chemotherapy or subsequent salvage regimen.

    Note: Relapse is defined as progression after a complete response to therapy or radiographic evidence of active disease after a partial response or stable disease.

  7. Have received three or fewer complete courses of systemic cytotoxic regimens. Note: Rituximab (alone or in combination with cytotoxic chemotherapy) is not considered a cytotoxic regimen.
  8. No previous exposure to PNT2258.
  9. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
  10. Have discontinued all prior anti-cancer therapies for at least 21 days; biologic therapy for at least 4 half-lives of the drug(s); radio-immunotherapy (10 weeks); autologous stem cell transplantation (SCT) (3 months) and must be at a stable baseline regarding any acute toxicity associated with prior therapy.
  11. Adequate organ function including:

    1. Hematologic Function: absolute neutrophil count (ANC) ≥ 1.5 x 109/L prior to treatment. Platelets ≥ 100 x 109/L.
    2. Hepatic: Total Bilirubin ≤ 1.5 x ULN and serum transaminase levels ≤ 2.5 x upper limits of normal (ULN).
    3. Renal: Serum creatinine ≤2 x ULN or creatinine clearance ≥ 60 mL/min/1.73 m2 for subjects with serum creatinine levels above 2x ULN.

Exclusion Criteria:

  1. Candidates for HDT and autologous SCT. Note: Patients who progressed > 3 months after high-dose therapy (HDT)/SCT are eligible.
  2. Concurrent malignancies requiring treatment.
  3. Symptomatic central nervous system (CNS) or leptomeningeal involvement of lymphoma.
  4. Concurrent serious medical conditions (as determined by the Principal Investigator) including, but not limited to, HIV-associated lymphoma; active bacterial, fungal or viral infections.
  5. Signs and symptoms of heart failure characterized as greater than New York Heart Association (NYHA) Class I.
  6. History of myocardial infarct or prolonged corrected QT (QTc) interval (>450 milliseconds (msecs) for males or >470 msecs for females) or other significant cardiac abnormalities.
  7. Women who are pregnant or breast-feeding.
