MP vs MPT: Response rates In all 5 studies, MPT was better than MP in terms of response, including CR+VGPR
MP vs MPT : PFS and OS In 5/5 studies, MPT was superior to MP in terms of PFS and/or TTP. In 2/5 studies, MPT was superior to MP in terms of OS. 1.

MPT/CTDa Studies : Conclusions • Five studies (GIMEMA, IFM 99-06, IFM 01-01, NMSG, HOVON) have shown that the use of thalidomide in combination with MP (MPT) improves response rates and TTP and/or PFS compared with MP • The 2 IFM studies have shown that MPT improves OS compared with MP, extending OS by approximately 18 months • Preliminary analysis of the results of MRC IX are consistent with MP vs MPT findings MPT is a new standard of care for newly diagnosed elderly patients with myeloma. CTDa might become another standard treatment for older less fit patients. EMEA approved front-line MPT in elderly MM patients in April 2008.

Newly diagnosed elderly patients with MM • Symptomatic treatments remain essential • Highest doses of drugs are not always optimal Dexamethasone MPR dose escalating study • Avoid excessive toxicity careful treatment monitoring dose reduction guidelines particurlarly in patients with bad performance status and in early stages of treatment • Outpatient administration of drugs should also befavored andpatient quality of life is important
Open questions… • How to reduce toxicity ? Dose reduction guidelines DVT prophylaxis • How to tailor treatment ? Cytogenetic abnormalities Comorbidities Renal function • How to delay relapse ? Role of maintenance treatment
Conclusions • MPT and MPV currently appear to be the treatments of choice for a large proportion of elderly MM patients ineligible for ASCT. • CTD, MPR, and Rd are other promising therapeutic options which are currently being evaluated. • MP remains appropriate for a minority of patients with poor performance status and/or significant comorbidities. • These new and emerging therapies offer multiple effective treatment options for MM patients and greatly enhanced treatment strategies for clinicians.
