PALADIN LABS INC. RECEIVES APPROVAL FOR THE SALE OF VALTAXINTM

Paladin Labs Inc. ("Paladin") (TSE: PLB) is pleased to announce today that the Therapeutic Products Programme ("TPP") has granted ValtaxinTM a notice of compliance permitting the sale of ValtaxinTM in Canada.

In June 1999, Paladin acquired the exclusive Canadian distribution rights for ValtaxinTM (valrubicin) from Anthra Pharmaceuticals, Inc. a US-based pharmaceutical company which focuses on the development of oncology therapeutics.

ValtaxinTM is a chemotherapeutic anthracyline derivative indicated for intravesical therapy of refractory carcinoma in-situ (CIS) of the bladder. Refractory cases are those who have failed conventional first-line therapy with standard-of-care agents and are candidates for surgical removal of the bladder. In clinical trials, intravesical therapy with ValtaxinTM has been shown to allow one-third of patients to retain their bladders for up to four years.

Bladder carcinoma is the sixth most common cancer in Canada with an incidence of 4800 cases per year. Of all patients diagnosed, approximately 15% are afflicted with CIS. Only 70% are responsive to BCG , the current gold standard of therapy. Currently, in Canada, there is no therapeutic alternative to cystectomy for patients who have failed all other modalities of treatment. In the US, ValtaxinTM is the only FDA-approved agent specifically indicated for intravesical treatment of CIS and has Orphan Drug designation for this purpose.

Jonathan Goodman, President & CEO of Paladin stated "ValtaxinTM is the first approved treatment for refractory CIS patients in Canada. We are confident that ValtaxinTM will increase the quality of life for patients whose only other recourse is surgical removal of the bladder. We are pleased at how quickly ValtaxinTM navigated through the TPP having received regulatory approval in less than 6 months from our application."
