Celecoxib

This study sought to define the cardiovascular effects of COX2 inhibitors when used for ar thritis and musculoskeletal pain in patients without coronar y ar ter y disease. A MedLine search was used and identified two major randomised trials: the Vioxx Gastrointestinal Outcomes Research Study VIGOR; 8, 076 patients ; and the Celeocxib Long-term Ar thritis Safety Study CLASS; 8, 059 patients ; . Two smaller trials with approximately 1, 000 patients each were also included. The results from VIGOR showed that the relative risk of developing a confirmed adjudicated thrombotic cardiovascular event myocardial infarction, unstable angina, cardiac thrombus, resuscitated cardiac arrest, sudden or unexplained death, ischaemic stroke and transient ischaemic attacks ; with rofecoxib treatment compared with naproxen was 2.38 95% confidence inter val 1.39-4.00; p 0.002 ; . Myocardial infarction was five times higher with rofecoxib 0.5% ; than with naproxen 0.1% ; , and risks of stroke, venous thrombosis and hyper tension were also significantly increased. There was no significant difference in cardiovascular event rates between celecoxib and non-steroidal anti-inflammator y agents in CLASS. The annualised myocardial infarction rates for COX-2 inhibitors in both VIGOR and CLASS were significantly higher than those in the placebo group of a recent meta-analysis of 23, 407 patients in primar y prevention trials 0.52% ; : 0.74% with rofecoxib p 0.04 compared with the placebo group of the meta-analysis ; and 0.80% with celecoxib p 0.02.

Women on short-term treatment with any of the above-mentioned classes of drugs or individual drugs should use a barrier method temporarily in addition to the combined oral contraceptive, during the time of concomitant drug administration and for 7 days after their discontinuation, for example, celecoxib metabolism.

Top- Prostate adenomectomies: a need for reconstructive surgery J. Monseur. Univ. RD Congo Lubumbashi ; , retired, Caen, France A true cultural revolution is currently developping : patients demand more and more to give their appreciation on medical care. World celebrities like Christopher Reeves draw attention and famous medical revues like British Medical Journal take up the challenge. First of all physicians and doctors who are patients themselves dare questioning ancient principles. As an urological surgeon who has undergone an open adenomectomy of the prostate I wish to emphasize the too often hidden insufficiencies of adenomectomies in the state of the art, for open as well as cystoscopic procedures. Simply removing benign adenomatous tumor does not restore the normal status. After the best done operation still remain physiological anomalies : - absolute loss of ejaculation and fertility - variable loss of mictional control - variable persistence of urgency Experimenting for techniques of recontruction of the prostatic capsule and the bladder neck, at the moment of operation or later, would probably seem more appealing in the field of clinical and surgical research if men who detain the medical power were older and subjects themselves to this kind of incommodities. At least the question should be a matter of discussion in men's health congresses i.e. in view of personal health and scientific knowledge not in view of state money cost. top- Biochemical Markers for Anxiety and Depression D.A. Rafter. General Practice, Dublin, Ireland The results of research into a biochemical marker for depression are presented. The research was carried out on a normal population in a primary care setting. Cholesterol levels were identified as the blood marker for anxiety and depression. The Hamilton Rating Scale for Depression was chosen to identify depression. Those with low cholesterol scored significantly higher on the Hamilton scale. Aim To facilitate the identification of Anxiety and depression. Objectives Understand a concept that anxiety and depression are chemical illnesses. Appreciate the role of the blood marker in identifying them. Make decisions about treating anxiety and depression based on those markers. Make decisions about, thus preventing the illnesses that anxiety and depression cause. Make decisions about screening via utilization of the blood procedure. Recognise and utilize the chemical screening test with emphasis on disease modification.

The PEM study conducted for celecoxib was conducted as described previously for rofecoxib [44]. For this study, exposure data were obtained from green forms received for patients identified from NHS prescriptions written by GPs in England for meloxicam between December 1996 and March 1997 n 19 087 ; and for celecoxib between May and December 2000 n 17 458 ; . For comparative purposes the exposed are those patients prescribed celecoxib and the unexposed are those patients prescribed meloxicam. As described previously [26], the event terms for this study were selected by medical practitioners from the DSRU dictionary prior to the analysis and aggregated into the three TE groups cardiovascular, cerebrovascular and peripheral venous thrombotic ; events Table 1 ; . The data were subject to the same inclusion and exclusion criteria as specified previously, for calculation of person-time exposed pte ; [26, 44, 45].

Why Counselling? Having a child is a major life event for any individual and couple. When this is proving difficult to achieve, and requires medical intervention, it can feel like a major life crisis. The emotional `ups and downs' experienced by those trying for a baby and undergoing treatments are well recognised within the field of infertility. For this reason the opportunity for counselling is included as part of the Centre's overall care, and is in accordance with the requirements made of all licensed treatment centres. How can Counselling Help? Whatever the surrounding circumstances, nature of infertility and eventual outcome of any treatment, those who are experiencing difficulties often find they need to talk to someone who will help them to: Make sense of how they are feeling. Explore and clarify their thoughts and concerns. Understand their reactions and ways of coping. Identify choices and make decisions about their lives- including whether or when to start treatment, go for a certain kind of treatment or stop treatment altogether. Plan their future with or without children. Come to terms with treatment not being successful, available or possible at all. A Counsellor is trained to be such a person who is independent of others and, when working in reproductive medicine, is informed about the medical and technological procedures as well as the legal, social and psychological aspects of infertility and treatment. With What Can Counselling Help? Relationships: The `roller coaster ride' of investigations, diagnosis, treatment and results can put a strain on relationships. For a couple, the time when one partner most needs the help of the other may be the time when it is least available, as each tries to cope and is not always able to give the support wanted. There may be differences between partners in the way each perceives and responds to a given situation or difficulty. This can affect communication and sexual relationships to varying degrees, at varying times. Counselling can help to address these and other problems that may arise for individuals or couples. It may also help in resolving pressures or tensions in relationships with family, friends, colleagues and other significant persons. Specific Procedures: There are certain health and or medical conditions, types of treatment and courses of action which raise particular issues: Donating eggs, sperm or embryos. Having treatment using donated eggs, sperm or embryos. Embarking on surrogacy. Applying for adoption or fostering. Foregoing all pursuit of parenthood. Counselling provides an opportunity for those who are considering any of these options to talk through all the implications with someone who is independent of any decision or actual procedure. Feelings of Loss: Having children is what most of us expect to be able to do when we decide we want to. When this does not happen there can be a loss of self- confidence and self-esteem, along with a sense of being incomplete and not having control. Feelings of isolation and failure as a man or woman, son or daughter, husband wife or partner can also occur. The Committee considered the issue of rare diseases as a result of concerns expressed about the possible deletion of factor VIII and factor IX and medicines for other rare diseases also known as "orphan diseases". The Committee reviewed the discussion paper entitled Rare essentials? Drugs for rare diseases on the Essential and erythromycin.
Core members were given the necessary support to enable them to participate in the network. This was achieved through managing formalized partnerships for implementing specific tasks for the network. Every effort was made to make the activities relevant the institutions and to SADNET. Mutual benefits were then realized by both the network and the core group. Activities conducted by the core group included training, facilitating documentation, sourcing relevant information for the network and disseminating it through several means. The core groups could have been more effective in providing lessons if private sector and certain government institutions were involved in activities. Output 600: Appropriate ICT applications for SADNET defined and implemented. Research on different ICT options and their suitability as information exchange media for the network. Pilot testing of possible ICT options and report on results. Investigating the appropriateness and utility of advanced and or alternative forms of telecommunications to transmit important information to rural communities focused on application of radio, video, Internet and email. These were, within the context of SADNET, the modern technologies that could provide more opportunities for effective information exchange. The main focus of this output was therefore on Email, Internet World Space radio and Radio-Internet. Other more traditional ICTs such as video and radio were considered under output 300. Research was conducted on ICT options and results analysed of their suitability as information exchange media for the network. This was conducted at three different levels. These were i ; between partner institutions, ii ; between partner institutions and communities and iii ; between communities. The pilot programme was implemented in slightly different ways in Zambia and Zimbabwe. In Zambia, Radio Internet was pilot tested whilst in Zimbabwe Internet, email and Cyberspace radio were pilot tested in 3 rural information centers. In Zimbabwe the implementation of the ICT the Open Knowledge Network OKN ; being run by SAFIRE complemented this option. OKN provided more resources to purchase additional computer and radio equipment for rural information centers. In addition, partners who did not have adequate capacity were assisted with computer upgrades and email and Internet connectivity to allow them to actively participate in the pilot test. Options defined at different levels The outcomes of the ICT promotion are discussed at each level. At community level: ICT options tested at community level aimed to identify the possible strategies to avail ICTs to rural communities. By the end of the project three rural information centers in Zimbabwe were running and using internet and email for communication and information dissemination. Whilst in Zambia RANET had re-established in Luangwa and was being used as a communication tool between communities and 18, for example, celecoxib 100 mg. `My thoughts as a teenager were that I wanted to just be normal. Having arthritis was hard enough to deal with, taking daily medication was irritating and having surgery was just another way to feel different from everyone else. Now that I older I can understand the reasons why I needed surgery and can see the positive improvements it has made to my quality of life. My own personal experience of operations has changed as I've got older. This is due to the support and understanding I've had.Things were explained to me, not in every detail as it would have just made me more anxious, but enough to help me understand and be able to reach a decision. Having support from people around helps enormously. It can't take away the arthritis, it can't take away your fears, your questions or your wishes, but it does make it easier to cope with, especially when you feel you can talk it over and explain fears and frustrations no matter how insignificant they seem. In my teenage years I found everything quite daunting. Often I didn't understand what was being said and just the word `operation' was scary enough. My rheumatologist would explain it to my mum, first in medical terms and then in simple terms. She would explain the operation, the procedure, advantage and both short- and long-term effects. When we got home, my mum and I would talk about it, mostly about the exact operation and the advantages, in ways that made sense to me. I've had over ten operations on my fingers, toes, knees and hips, starting when I was 10 years old. All of my operations have been a success, although there has been some nerve damage, which unfortunately cannot always be avoided. If I had to say if the operations had changed my life for the better, I would have to say both yes and no.`Yes', because they have decreased my pain, improved the movement of my joints and improved my quality of life.`No', and this may sound a little ungrateful, because of the physical scars they leave. All said, I pleased I had the operations I would not turn the clock back and say no if I could. Also, surgical techniques have improved dramatically since I was a teenager, particularly with respect to keyhole surgery and better techniques of stitching which leave minimal scarring. I have experienced the benefits of surgery first hand and the improvement it has made to my quality of life. If I hadn't had any of the operations I would almost certainly have to use a wheelchair some of the time, if not all of the time.' and exelon.

From the CLASS study we know that celecosib is no safer than ibuprofen on the GI tract and may be less safe on the heart, and from the FDA review of celfcoxib we know it is no more effective than other NSAIDs for osteoarthritis. A similar result is obtained for rofecoxib. Our elderly patient pays $71 a month more, $852 a year more ; for a drug that is no more effective for osteoarthritis, no safer on the GI tract, and perhaps less safe on the heart than ibuprofen. This is what happens when big drug companies are allowed into our medicine cabinets and push us to choose the drugs we use by advertising that is sometimes false and misleading. Since celecoxih was approved, the FDA has issued five Notices of Violation and one Warning Letter to Pharmacia about the false and misleading advertising regarding the safety and effectiveness of celecoxib. The Warning Letter was issued February 1, 2001, just one week before the Arthritis Drugs Advisory Committee meeting instructed the company to produce and distribute advertising to correct ongoing false and misleading claims it had made about celecoxib. Merck has received two Notices of Violation letters from the agency about the false and misleading advertising of rofecoxib. What You Can Do In light of the above discussion, we continue to recommend the fiveyear patient-protective rule for these drugs, as we do for all other new products that are not true breakthroughs: Do Not Use until five years after release. In the case of these two drugs, the clock still has about three years to run and floxin. The average age of subjects was 62 1.5 yr, and body mass index was 25.8 1.9 kg m2. The mean total cholesterol level was 5.7 0.2 mmol liter, high-density lipoprotein cholesterol was 1.9 0.1 mmol liter, low-density lipoprotein was 3.5 0.2 mmol liter, triglycerides were 1.0 0.1 mmol liter, and estradiol was 86 6 mmol liter. Average blood pressure was 119 67 3 Hg. Full blood count and liver function tests were in the normal range at all time points in all cases. None of these variables changed significantly during the course of the study. The vasodilator response to ACh, before E administration, was significantly greater after celecoxib than after placebo 273 to 1373 212 arbitrary perfusion units; P 2679 0.0004 ; but was unaffected by aspirin and diclofenac. The blood flow response to SNP was not altered by placebo or any of the treatments P 0.261 ; After placebo, aspirin, and diclofenac, acute E administration significantly enhanced the vasodilator response to ACh over the 34 min time course. However, after celecoxib this potentiation of ACh-mediated vasodilation by E was completely abolished P 0.05; Fig. 1 ; .

Celecoxib research

Elicit any appreciable effect on fluo-3 fluorescence. This observation excluded the possibility that celecoxib caused [Ca2 + ]i increase by perturbing membrane permeability. Celecoxib-stimulated Ca2 + response is attributable to ER Ca2 + release and capacitative Ca2 + entry. Kinetics of celecoxib-induced Ca 2 + response in PC-3 cells was further examined Fig. 2 ; . Suspended PC-3 cells were loaded with fluo-3, and Ca2 + response to celecoxib was monitored by fluorescence spectrophotometry. Insert Fig. 2 Panel A indicates [Ca2 + ]i changes following the treatment with 50 and 100 M celecoxib. Exposure to 50 M celecoxib stimulated a transient [Ca2 + ]i increase, whereas 100 M celecoxib gave a robust, sustained [Ca2 + ]i elevation with a significantly higher amplitude. This Ca2 + response was quantitatively different from that observed with digital ratiometric measurement Fig. 1 ; . This discrepancy might, in part, be accounted for by differences in the cell preparation, i.e., cell suspension versus monolayers, and assay conditions. Panel B suggests that the Ca2 + response elicited by 100 M celecoxib was largely due to Ca2 + influx from the medium. Trace a shows changes in [Ca2 + ]i following two tandem treatments of 50 M celecoxib. As shown, after the Ca2 + transient leveled off to the baseline following the initial treatment, a subsequent challenge stimulated a gradual rise in [Ca2 + ]i to level similar to that elicited by 100 M celecoxib alone. The second [Ca2 + ]i increase, however, could be abrogated by removing external Ca2 + with EGTA trace b ; , whereas the first Ca 2 + transient was not much affected. Moreover, pretreatment of cells with thapsigargin 1 M ; in the presence of EGTA to deplete the internal Ca 2 + stores also blocked [Ca2 + ]i increase caused by 50 M celecoxib Fig. 2C ; . These data suggest that the transient elevation in [Ca2 + ]i was attributable to Ca2 + release from internal Ca 2 + stores, whereas the second Ca2 + signal was due to Ca2 + influx from the medium. This premise is in line with the capacitative Ca2 + entry theory that the depletion of intracellular Ca2 + stores signals an influx of Ca2 + across plasma membranes through Ca2 + released-activated Ca2 + CRAC ; channels or store-operated Ca2 + channels ; [35, 36]. Consequently, an important question arose as to how celecoxib induced Ca2 + release from internal stores. In principle, internal Ca2 + release might be mediated via one of the following Ca2 + -transporting mechanisms on ER membranes: a ; IP3 receptors, b ; ryanodine receptors, and c ; ER Ca -ATPase or SERCA ; pumps [37, 38]. Activation of IP3 receptors or ryanodine receptors gives rise to Ca2 + release from the respective Ca2 + stores. With regard to the third mechanism, inhibition of the ATP-dependent Ca2 + pump by specific inhibitors such as thapsigargin results in rapid release of ER Ca2 + into the cytosol via ER Ca2 + leak channels [39]. To test the first and second possibilities, we examined the effect of pharmacological inhibitors specific for IP3 receptors or ryanodine receptors on celecoxib-induced Ca2 + release from microsomes or permeabilized cells. Ccelecoxib does not affect IP3 - or ryanodine-sensitive Ca2 + stores. To test the effect of celecoxib on IP3 -sensitive Ca2 + stores, the microsomal fraction of PC-3 cells was prepared, suspended in an assay buffer containing fluo-3, and treated with ATP 2 mM ; for Ca2 + -loading. Addition of IP3 10 M ; and subsequent exposure to celecoxib 50 M ; each resulted in immediate Ca2 + release into medium Fig. 3A; upper panel ; . The amplitude of Ca2 + response elicited by celecoxib was greater than that of IP3 , indicating that IP3 did not desensitize the Ca2 + release mechanism mediated by celecoxib. Treatment of the microsomes with heparin 200 g ml ; , an antagonist of IP3 receptor [40, 41], abolished IP3 induced Ca 2 + release, but imposed no effect on celecoxib-mediated Ca2 + increase lower panel ; . Taken together, these data suggest that celecoxib did not affect IP3 -sensitive Ca2 + stores. 6 and fluoxetine.

22005 24001: Randomized study for the definition of the optimal target volume in radiotherapy for cervical lymph node metastases of squamous cell carcinoma V. Grgoire, M. Pierart ; The study coordinator explained the present situation and the slow start of the study. He will be contacting personally all those centres who indicated their intention to participate to try and find out the status of their regulatory procedures and the possible reasons for any delay. Only after this will he be able to make a realistic evaluation of the feasibility of the study. Head & Neck Cancer Working Party Report Coordinators: V. Grgoire, Brussels and M. Ozsahin, Lausanne ; . The agenda of the WP was a follow-up of the discussion started in Tbingen on different proposals for primary and post-operative radiotherapy in HNSCC. 1. Update on the proposal on peri-operative chemotherapy: J. Bernier Bellinzona ; J. Bernier presented an update on the peri-operative chemotherapy protocol, designed as an approach to potentially overcome tumor proliferation before the start of postoperative chemotherapy. The trial will be designed as a phase I trial for high risk patients according to the criteria defined by L. Peters et al. Chemotherapy paclitaxelcarboplatine ; will be started not later than 7 days after surgery and for a maximum of 6 courses. Thereafter, concomitant cddp-radiotherapy will be started. The main endpoint is acute toxicity and the secondary endpoints are tumor response, loco-regional control, disease-free survival and late toxicity. The sample size has been calculated at 28 patients and the study will be closed when more than 2 patients experience a postoperative fistula. During the discussion, it has been suggested to replace fistula by wound healing. The study has been submitted to the PRC. 2. Post-operative concomitant Cox-2 inhibitor and radiotherapy: W. Budach Tbingen ; W. Budach presented his proposal on concomitant Cox-2 inhibitor celecoxib ; and postoperative radiotherapy in patients with intermediate risk according to L. Peters criteria ; after curative surgery. For this group of patients, radiotherapy alone can still be considered as standard. In this randomized phase II III trial, patients are randomized between post-operative radiotherapy plus placebo or post-operative radiotherapy plus celecoxib 400 mg bid ; . At the end of radiotherapy patients would be further randomized for maintenance celecoxib 400 mg bid for 2 years ; or placebo. This second randomization addressing a different question effect of celecoxib on the incidence of second primary ; could be proposed to all patients irrespective of their first arm. The phase II would be designed to assess the acute toxicity at 3 months after start of treatment. If acute grade III-IV toxicity is not increased by more than 20% from 60 to 80% ; in the experimental arm, then a phase III trial will be designed with overall survival as main endpoint. For the second randomization, the main endpoint is reduction of second primary. Assuming a relative reduction of 33% of deaths in the celecoxib arm, an estimated total number of patients of 400 altogether for the phases II and III ; would be needed. A translational research component tissue micro array ; will be added to this study and ilosone. Primary Objectives: To assess the disease free survival DFS ; benefit of two years adjuvant therapy with the COX-2 inhibitor celecoxib compared with placebo in primary breast cancer patients. Secondary Objectives: To compare overall survival To define the safety of adjuvant therapy with celecoxib in this patient population To compare incidence of second primary cancers In postmenopausal hormone receptor HR ; positive patients, to assess tolerability of celecoxib with tamoxifen. 5. To assess DFS benefit of two years adjuvant celecoxib compared with placebo in HR positive i.e. ER positive and or PR positive ; and in HR negative i.e. ER negative PR negative ; disease. Tertiary Objectives: To investigate COX2 level and other tumour associated proteins in the tumour tissue and relate these findings to trial outcome. Addenda: Final Protocol Version incl. Amd. 1, 11.09.2006 Study chair Report: The primary aim is to assess the disease free survival DFS ; benefit of two years adjuvant therapy with the COX-2 inhibitor celecoxib compared with placebo in primary breast cancer patients. There are multiple reasons for initiating a randomised study to examine the impact of COX-2 inhibition in enhancing the adjuvant treatment of breast cancer - as follows inhibition of angiogenesis inhibition of cell growth inhibition of tumour-associated inflammation inhibition of invasion promotion of apoptosis The proposed study will assess the potential of COX-2 inhibitors as "maintenance therapy", following surgery with or without chemotherapy + or - radiotherapy ; , to improve disease free survival of patients with primary breast cancer. 1. 2. 3.

Stanfield1 of Biological Sciences, The University of Warwick, Coventry, UK, 2Department of Cell Physiology & Pharmacology, University of Leicester, Leicester, UK and 3Manchester Interdisciplinary Biocentre, University of Manchester, Manchester, UK The inward rectifier K + channel Kir2.1 is gated by blockage by intracellular polyamines and Mg2 + , whose occupancy of the channel is opposed by extracellular K + . aspartate residue D172 ; located in the second transmembrane domain M2 ; and two glutamate residues E224 and E299 ; in the cytoplasmic pore have been identified as binding sites for these blockers for review, see Stanfield et al. 2002 ; . The mechanism of channel blockage by polyamines is however not fully established. To begin to test whether polyamines come into close proximity with the channel selectivity filter, we have examined the effect of mutation of T142 in the K + selectivity sequence TIGYG on channel gating. Channels were expressed in oocytes taken from Xenopus frogs. We used two-electrode voltage clamp to examine current-voltage relationships of wild type and mutant channels. Normalised conductance-voltage relationships Fig. 1 ; were fitted using a Boltzmann relation with two components each of which evaluates to 0.5 at membrane potentials V1 and V2 with steepness factors k1 and k2. V1 was altered from -44.0 1.0 mV mean s.e.m; n 6 ; in wild type to -54.4 0.5 mV n 5 ; T142A, while V2 -103.9 8.8 wild type ; and -115.9 0.7 T142A ; . k1 and k2 were little altered: k1 13.7 0.3 and 12.6 0.4mV in wild type and T142A, respectively; k2 20.6 2.6 and 24.1 0.8mV. The shift in V1 to more negative values in the T142A mutant would be consistent with an increase in polyamine affinity of the mutant channels, an increase which we are in the process of testing using macropatches. Inspection of the time course of current development under hyperpolarisation is suggestive of a slower release of polyamines in the mutant. Our results are consistent with polyamines binding deeply in the channel, in part adjacent to the intracellular end of the selectivity filter. Alternatively, since the mutation may disrupt one of the K + co-ordination sites in the selectivity filter Zhou & MacKinnon, 2004 ; , our results may also be explained by reduced competition between extracellular K + and the blocking polyamine. We are currently testing these hypotheses, for example, action of celecoxib.

The predominant cause of shortened column lifetime in low pH mobile phases relates to the acid hydrolysis of the bonded phase. This hydrolysis can lead to significant changes in analyte retention time, making method suitability requirements difficult to achieve. XBridgeTM packings incorporate the use of well-characterized, state-of-the-art, proprietary procedures for bonding and endcapping. Bonded phases prepared using these procedures are much more stable and reproducible at low pH than conventionally prepared materials and resist the typical ligand hydrolysis failure. In an accelerated low pH stability test, XBridgeTM C18 columns show very little retention loss and exhibit a column lifetime equivalent to that of a sterically hindered C18-silica-bonded phase. Accelerated Low pH Stability Tests of Competitive Columns.

Context: There is increased cyclooxygenase-2 COX-2 ; expression in malignant thyroid nodules compared with nonneoplastic and benign thyroid tissue. Objective: The objective of the study was to evaluate the efficacy of celecoxib, a selective COX-2 inhibitor, in treating patients with progressive metastatic differentiated thyroid cancer DTC ; and to explore the relationship of clinical response to tumor COX-2 expression with immunohistochemistry in a subset of patients. Design: The study was a prospective phase II trial with Fleming single-stage design powered at 80% with a 5% rejection error to detect more than 20% progression-free survival at 12 months. Setting: Ambulatory patients were from tertiary referral academic medical centers. Patients: Patients in the study had progressive metastatic DTC and had failed prior standard therapy. Intervention: Patients were treated with celecoxib 400 mg orally twice a day for 12 months. Main Outcome Measure: The main outcome measure was progression-free survival at 12 months of treatment using Response Evaluation Criteria in Solid Tumors and or serum thyroglobulin. Results: Twenty-three of 32 patients experienced progressive disease or stopped therapy due to toxicity, thus fulfilling the intent-to-treat study endpoint for celecoxib failure. One patient achieved partial response, and one patient completed 12 months of therapy progression-free. The patient with partial response was on therapy along with seven other patients when the study was terminated. Conclusions: Celecoxi 400 mg orally twice per day fails to halt progressive metastatic DTC in most patients. J Clin Endocrinol Metab 91: 22012204, 2006.
