THALIDOMIDE Thalidomide continues to show benefit in a wide variety of settings. Thalidomide plus dexamethasone is very active as a frontline approach see section 3: [45-49] ; . Thalidomide alone or combined with alpha interferon has shown early benefit as a maintenance strategy 47 ; . Further studies are required. Low-dose thalidomide 50-100 mg day ; both alone and combined with dexamethasone improves survival in advanced multiple myeloma 47, 109 ; . In the recent Italian study 110 ; , Thal Dex as salvage therapy for advanced myeloma produced a 52% response rate 50% reduction in M-component ; with a median progression-free survival of 12 months and median overall survival of 27 months, which is better than what is achievable with conventional chemotherapy salvage P .05 ; . Thalidomide is currently being evaluated as part of combination therapy in numerous studies e.g. plus melphalan or cytoxan ; . Of particular interest, thalidomide plus bortezomib VELCADE TM ; with or without dexamethasone has shown benefit in refractory myeloma post auto transplant with chromosome 13 deletion 110 ; . REVIMIDTM CC-5013 ; Preliminary results of a phase II trial were presented at ASH 2002 111 ; . Table 20 summarizes the response rates at different dose levels of RevimidTM. Of note, dexamethasone enhanced response to RevimidTM. RevimidTM appeared to have been well tolerated with no neurologic side effects such as neuropathy, sleepiness, or constipation in early testing. Neutropenia was a problem, which has led to a 3 weeks on 1 week off schedule for further testing. Several trials are now ongoing, including a phase III trial of dexamethasone versus RevimidTM plus dexamethasone. VELCADETM bortezomib, formerly PS-341 ; Final results of the 202 patient, multicenter, phase II "SUMMIT" trial of VELCADETM in heavily pretreated 6 median prior lines of therapy ; patients with relapsed and refractory myeloma were presented at ASH 2002 112 ; . The response rates, according to the criteria defined by Blade 117 ; and confirmed by an independent review committee, are summarized in Table 21. The overall response rate CR + PR was 35%. Of note, the median response duration was 12 months and median overall survival was 16 months This compares favorably to the 6 9 months survival in refractory patients reported in the literature. Results in earlier stage disease in the "CREST" study were also presented 113. I. Jun, S. Lee, T. Jeon, G. Kim, D. Lee, C. Jin, S. Lee and T. Jeong.

Anthricin has recently been characterized to have beneficial activities in regulating immediate-type allergic reaction and anti-inflammatory activity through the dual inhibition of cyclooxygenase-2 and 5-lipoxygenase. To study the metabolism of anthricin in rat liver microsomes, anthricin was incubated in the presence of NADPH generating system. Metabolites were detected by liquid chromatography electrospray ionization-tandem mass spectrometry analysis. At least four major peaks M1, M2, M3 and M4 ; were observed. Among them, the metabolite M4 was believed to be a major metabolized product, podophyllotoxin, hydroxylated on the C-ring of anthricin. Using enriched rat liver microsomes, the anticipated isoforms of cytochrome P450s in the metabolism of anthricin were partially characterized. Phenobarbital-induced microsomes greatly increased in the formation of the metabolite M2. Dexamethasone-induced microsomes increased in the formation of metabolite M4. The metabolites M1 and M3 were only produced in enriched microsomes isolated from phenobarbital- and dexamethasone-treated rats. The present results indicated for the first time that anthricin could be metabolized by cytochrome P450 in rat liver microsomes. Supported by the grant from Korea Research Foundation, E00004.

Mation, and decongestants such as oxymetazoline hydrochloride. While the use of intranasal corticosteroids has been shown to be helpful, 47, 48 there are no prospective, randomized, double-blind studies that have proven that either nasal or oral decongestants are efficacious in either acute or chronic sinusitis. No one has investigated the efficacy of any of these medicines on acute cough that is related to acute sinusitis. The treatment of chronic sinusitis is even less clear-cut. The role of bacterial infection and the importance of antibiotic therapy are controversial. However, in four prospective descriptive studies13, 13 the following initial treatment regimen has been efficacious: a minimum of 3 weeks of treatment with an antibiotic effective against H influenzae, mouth anaerobes, and S pneumoniae; a minimum of 3 weeks of oral treatment with an older-generation A D twice per day; and 5 days of treatment with a nasal decongestant twice per day. When cough disappears with this therapy, intranasal corticosteroids should be continued for 3 months. In patients with documented chronic sinus infection that appears to be refractory to medical therapy and in whom anatomic obstruction is present that is thought to be amenable to endoscopic sinus surgery, this option should be considered. Treatment for allergic fungal sinusitis has centered on the surgical removal of the allergic fungal mucin and the subsequent aeration drainage of any involved sinus.30 Unlike allergic bronchopulmonary mycosis, steroid therapy is only suppressive. The role of oral antifungal agents, however, though inadequately defined, may be of potential value and a worthwhile option to consider prior to proceeding with surgery. Rhinitis Due to Physical or Chemical Irritants Including Occupational Exposure ; When environmental irritants are identified, the avoidance of exposure, improved ventilation, filters, and, in rare circumstances, the use of personal protective devices eg, dust mist fume masks with high-efficiency particulate air filters for occupational exposures ; can be an effective part of therapy. Rhinitis Medicamentosa The key to therapy is the patient stopping or weaning off the offending agent. Sometimes this can be done one nostril at a time. The use of an A nasal corticosteroids seems reasonable, but there are no significant data available on their efficacy.

Canadian patients are eligible for clinical trials, and there are a lot of clinical trials in Canada, too. Would you want to say whether Canadians are participating in clinical trials? Yes, I think they certainly are. The NCIC [National Cancer Institute of Canada] I know has a number of trials, and I think the Canadians work through ECOG Eastern Cooperative Group ; as well; they have access to ECOG trials as well. So I think there certainly are a number of studies in all phases of disease. I know that there was a national induction study using Velcade and Doxil doxorubicin I think the accrual has been quite good in those trials. So I know that there certainly are; it is usually through the bigger centers though. Next question. Thank you. Our next question comes from Joanna from New York. Please state your question. On the 2 trials that Dr. Jagannath spoke of, trial 1 and trial 2. First of all, the second one, I need the spelling; I still have not gotten that clearly. And my next question is will steroids, dexamethasone, or prednisone be involved in those 2 trials, or are they without steroids? Sagar, do you want to answer that? So for the PR-171 trial, there will probably not be steroids in those trials because I think they do not really require steroids. For the tanespimycin, I happy to just be able to say it, spelling it is another challenge, but I think it is t-a-n-e-s-p-i-m-y-c-i-n, tanespimycin. For the tanespimycin trial, it really depends on which formulation they use in the phase 3 trial. If it is the older formulation, there will be a little bit of steroids as a premedication, but if it is the newer formulation, then there will not be steroids in that trial; it will be tanespimycin plus Velcade versus Velcade. Yes, tanespimycin is t-a-n-e-s-p-i-m-y-c-i-n. Thank you. Next question, please. Our next question comes from Ahmitab from Georgia. Please state your question. Yes, I would like to know if somebody has multiple myeloma with a chromosomal anomaly that is suggestive of myelodysplasia, would these drugs be effective in this kind of a condition? Yes, that is a very interesting question and a challenge, somebody has multiple myeloma and at the same time, they have myelodysplastic syndrome, and this was known because the doctor did the bone marrow and cytogenetic studies, and and vfend.
