 During 2005 and 2006 Solbec was granted orphan drug designation for Coramsine by the U.S. Food and Drug Administration in the treatment of renal cell carcinoma and for malignant melanoma respectively.2006 also saw the completion of Phase I/IIa trials and the commissioning of Phase IIb trials that would target renal cell carcinoma (stage III/IV) and malignant melanoma (stage III/IV), but in November 2006 shortly before their commencement Solbec postponed the trials due to Australia's Therapeutic Goods Administration (TGA) having concerns about the drug's pre-clinical data.A development plan for coramsine was approved by the TGA in May 2007 resulting in further pre-clinical studies, which were successfully completed in March 2008.
