Pre-clinical Studies Show Effectiveness of New Anti-cancer Product T h e Department of Biochemistry conducted a series of in-vitro and in-vivo pre-clinical studies for an anti- cancer product developed by CK Life Sciences International (Holdings) Inc. The results show that immune cells in mice fed with the product are activated while human liver cancer cells implanted in them are suppressed. The positive pre- clinical findings have prompted the two parties to launch clinical trials. Prof. Fung Kwok-pui, leader of the pre-clinical studies and professor of biochemistry, said, 'This clinical trial is a good example of cooperation between academia and commerce. ... Not only wou ld such collaboration speed up the pace of research, but it would also give wider recognition to study results.' Preliminary studies show that the orally-prescribed, yeast-based product can improve the immune system of cancer patients, reduce mortality rate, and promote recovery from chemotherapy and radiotherapy. It can also lessen common side- e f f e c ts caused by c hemo t he r apy and radiotherapy such as nausea, b l e e d i n g, edema, and deterioration of the immune system, and prevent complications and pain arising from surgery and injection.

Pang (middle), vice-president and chief technology officer of CK Life Sciences Breakthrough in Treatment for Autoimmune Disorder I mmune thrombocytopenic purpura (ITP), one of the most common autoimmune disorders today, results from autoantibodies working against our blood platelets. The Prince of Wales Hospital registers about 30 to 40 new cases annually. Patients with ITP have a higher risk of bleeding, which may be life-threatening. Costicosteroid is proven to be an effective first-line therapy for this disorder. Conventional treatment involves the use of prednisone and the treatment lasts for weeks to months. It increases the platelet count in about 75 per cent of adult patients. A prolonged course of corticosteroid therapy may lead to side-effects including infection, osteoporosis, hypertension and endocrine disturbances. From January 1977 to December 2000, the Division of Haematology of the D e p a r t m e nt o f M e d i c i ne and Therapeutics treated 125 adult ITP patients using a new regimen o f corticosteroid that contains a high dose of dexamethasone. The treatment lasted four days. Eighty-five per cent of the patients showed a positive i n i t i al response to the treatment and most were discharged from hospital by the third day of treatment. Half remained in remission without further treatment at six months' follow-up. Though just as effective as conventional treatment, the new regimen is safer. Its short duration minimizes the adverse effects of a prolonged course of corticosteroid therapy. It also produces a quicker response in patients and reduces the length of hospital stay. The breakthrough was published in The New England Journal of Medicine on 28th August 2003. Principal investigator Prof. Gregory Cheng (right) and Dr. S.M.
