According to the National Cancer Institute there are no active clinical trials (as of April 1, 2008). Completed and closed clinical trials are listed here: 
The molecular formula of suramin is C51H34N6O23S6. It is a symmetric molecule in the center of which lies urea, NH-CO-NH. Suramin contains eight benzene rings, four of which are fused in pairs (naphthalene), four amide groups in addition to the one of urea and six sulfonate groups. When given as drug it usually contains six sodium ions that form a salt with the six sulfonate groups.
Suramin is administered by a single weekly intravenous injection for six weeks. The dose per injection is 1 g.
Adverse reactions 
The most frequent adverse reactions are nausea and vomiting. About 90% of patients will get an urticarial rash (like a nettle or poison ivy-type rash) that disappears in a few days without needing to stop treatment. There is a greater than 50% chance of adrenal cortical damage, but only a smaller proportion will require lifelong corticosteroid replacement. It is common for patients to get a tingling or crawling sensation of the skin with suramin. Suramin will cause clouding of the urine which is harmless: patients should be warned of this to avoid them becoming alarmed.
Kidney damage and exfoliative dermatitis occur less commonly.
Suramin has been applied clinically to HIV/AIDS patients resulting in a significant number of fatal occurrences and as a result the application of this molecule was abandoned for this condition. http://www.ncbi.nlm.nih.gov/pubmed/3548350
It may have some activity against RNA viruses.
In addition to antagonism of P2 receptors, Suramin inhibits the acitivation of heterotrimeric G proteins in a variety of other GPCRs with varying potency. It prevents the association of heteromeric G proteins and therefore the receptors Guanine exchange functionality (GEF). With this blockade the GDP will not release from the Gα subunit so it can not be replaced by a GTP and become activated. This has the effect of blocking downstream G protein mediated signaling of various GPCR proteins including Rhodopsin, the A1 Adenosine receptor, and the D2 dopamine receptor.
- The formula of suramin was kept secret by Bayer for commercial reasons. But it was elucidated and published in 1924 by Fourneau and his team of the Pasteur Institute, and it is only on this date that its exact chemical composition was known. (E. Fourneau, J. and Th. Tréfouël and J. Vallée (1924). "Sur une nouvelle série de médicaments trypanocides", C. R. Séances Acad. Sci. 178: 675.)
