Phase II trial of copper-lowering drug in patients with advanced kidney cancer
You might want to check www.robertsreview.com. They not only have a
GREAT FDA Trials Finder Tool for this(scroll down left hand column)
and TERRIFIC, up-to-the-minute interviews (audio, video, and
transcripts) with leading doc's and researchers on new treatments,
{*filter*}, research breakthroughs, pain management, etc.. (I think they
also offer special financial help to cancer patients...along with "top
cancer treatment" hospitals/clinis???)
I check 'em once or twice a week at http://www.***.com/
Hope this may be of some help to you.

> PURPOSE: Tetrathiomolybdate (TM), a copper-lowering agent, has been shown in
> preclinical murine tumor models to be antiangiogenic. We evaluated the
> antitumor activity of TM in patients with advanced kidney cancer in a Phase
> II trial.
> EXPERIMENTAL DESIGN: Fif{*filter*} patients with advanced kidney cancer were
> eligible to participate in this trial. TM was initiated p.o. at 40 mg three
> times a day with meals and 60 mg at bedtime to deplete copper. A target
> serum ceruloplasmin (CP) level of 5-15 mg/dl was defined as copper
> depletion. Doses of TM were reduced for grade 3-4 toxicity and to maintain a
> CP level in the target range. Once copper depletion was attained, patients
> underwent baseline tumor measurements and then again every 12 weeks for
> response assessment. Patients not exhibiting progressive disease at 12 weeks
> after copper depletion continued on treatment. Serum levels of Interleukin
> (IL)-6, IL-8, vascular endothelial growth factor (VEGF) and basic fibroblast
> growth factor (bFGF) were assayed pretreatment and at various time points on
> treatment. Dynamic contrast enhanced-magnetic resonance imaging (DCE-MRI)
> was performed on selected patients in an attempt to assess changes in tumor
> vascularity.
> RESULTS: All of the patients rapidly became copper depleted. Thir{*filter*}
> patients were evaluable for response. No patient had a complete response or
> PR. Four patients (31%) had stable disease for at least 6 months during
> copper depletion (median, 34.5 weeks). TM was well tolerated, with dose
> reductions most commonly occurring for grade 3-4 granulocytopenia of short
> duration not associated with febrile episodes. Serum levels of IL-6, IL-8,
> VEGF, and bFGF did not correlate with clinical activity. Serial DCE-MRI was
> performed only in four patients, and a decrease in vascularity seemed to
> correlate with necrosis of a tumor mass associated with tumor growth.
> CONCLUSIONS: TM is well tolerated and consistently depletes copper as
> measured by the serum CP level. Clinical activity was limited to stable
> disease for a median of 34.5 weeks in this Phase II trial in patients with
> advanced kidney cancer. Serum levels of proangiogenic factors IL-6, IL-8,
> VEGF, and bFGF may correlate with copper depletion but not with disease
> stability in this small cohort. TM may have a role in the treatment of
> kidney cancer in combination with other antiangiogenic therapies.
