Primary Outcome Measures:
  • Maximum tolerated dose (MTD) of SSG in combination with IFN alpha2b [ Time Frame: 3 weeks ]
    MTD defined as the highest dose at which no dose limiting toxicity (DLT) occurs. Continuous assessment with each 3 week cycle.

Enrollment: 0
Study Start Date: September 2006
Study Completion Date: February 2010
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: SSG + Intron A
Sodium Stibogluconate (SSG) 400 mg/m^2 intravenous (IV) daily on days 1-5 + Interferon Alfa-2b (Intron A) 3x10^6 units subcutaneously three times weekly
Drug: Sodium Stibogluconate
400 mg/m^2 IV daily on days 1-5.
Other Name: SSG
Drug: Interferon Alpha-2b
3x10^6 units subcutaneously three times weekly
Other Name: Intron A

Detailed Description:

Primary objectives:

To determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of SSG in combination with IFN alpha2b in patients with advanced malignancies.

Secondary objective:

  • To correlate the AUC of SSG with clinical toxicity and efficacy;
  • To quantify the effect of SSG on IFN alpha2b induced gene modulation and signal transduction pathways;
  • To characterize the effects of SSG on PTPases SHP-1 and SHP-2.

To assess the safety, efficacy, and PK of SSG in combination with IFN alpha2b.


During Cycle 1, you will be given sodium stibogluconate once a day by vein during Days 1-5. On Days 8-12, you will be given sodium stibogluconate once a day by vein, and you will be given interferon alfa-2b for 3 days by injection just under the skin on Days 8, 10, and 12. For every cycle after Cycle 1, you will be given sodium stibogluconate once a day by vein during Days 1-5 and 8-12, and you will be given interferon alfa-2b for 3 days by injection just under the skin on Days 1, 3,5, 8, 10, and 12. Treatment cycles will last about 3 weeks (2 weeks on treatment, followed by 1 week off treatment). After Cycle 1, you will be scheduled to return to the clinic in 10 days to receive treatment for Cycle 2, which will follow in the same manner as Cycle 1.

Exclusion Criteria:

  1. Patients on concurrent immunotherapy, including IFN therapy (prior therapy is allowed if >/= 4 months since immunotherapy).
  2. Patients who have received investigational drugs including immunotherapy, gene therapy, hormone therapy, biologic therapy, radiation therapy, chemotherapy, or had major surgery within 3 weeks of study enrollment

  6. Pregnant or lactating women, and fertile women or men unless surgically sterile or using effective contraception; All female patients of childbearing potential or < 1 year postmenopausal must have a negative beta human chorionic gonadotropin (βhCG) pregnancy test at baseline and be practicing a medically acceptable method of birth control (oral contraceptives for at least 3 months, implantation of an intrauterine device at least 2 months, or barrier methods [e.g. vaginal diaphragm, vaginal sponge, or condom with spermicidal jelly]).
