This study has been completed.

The objectives of this Phase I/II study are:

  1. To find out the maximum tolerated dose (MTD) of PG2 in patients with advanced malignancy receiving chemotherapy and to define a "Study Dose" for Phase II.
  2. To evaluate the hematopoietic and immunological responses after administering of PG2. Primarily to study the biological response of PG2, defined as WBC count in this study, and secondarily to study the immunological factors, IL-2, IL-6, TGF-beta, and G-CSF.

Further study details as provided by PhytoHealth Corporation:

Primary Outcome Measures:
  • Phase I: To find the maximum tolerated dose (MTD) or the highest tolerated dose (HTD) as the study dose of PG2; Phase II: To use the study dose and assess the WBC level of PG2 [ Time Frame: within 14 days of each chemotherapy cycle ]

    For phase I study, the primary endpoint is to determine a safe dosage of PG2 by the dose escalation design.

    For phase II study, the primary endpoint is to compare the WBC level between PG2 plus chemotherapy and chemotherapy alone.

Secondary Outcome Measures:
  • Phase II: To use the study dose to assess the hematopoietic and immunological cytokine levels [ Time Frame: within 14 days of each chemotherapy cycle ]
    For phase II study, the secondary endpoint is to compare the levels of IL-2, IL-6, TGF-beta and G-CSF between PG2 plus chemotherapy and chemotherapy alone.

Inclusion Criteria:

  • Patient must have malignancy with metastatic or recurrent diseases.
  • Patient must have a minimum of thirteen days period elapsed from any previous chemotherapy or radiotherapy and all treatment-related toxicities subsided.
  • Patient must have at least 2 courses of chemotherapy treatment left, and a minimum of 13 days between the administration of the last dose of the chemotherapy with PG2 and the start of the next course of chemotherapy.
  • Performance status is 0-2 by ECOG scale.
  • Patient's compliance and geographic proximity that allow adequate follow up.
  • Adequate bone marrow function before the chemotherapy
