Little1 and Kieron Dunleavy1 1National Cancer Institute, National Institutes of Health, Bethesda, MD HIV is associated with an excess cancer risk, particularly of lymphoid malignancies. Modern therapeutics has changed the landscape of HIV disease and typical opportunistic complications of AIDS are now largely avoided. Although the risk of lymphoma has decreased, it still remains high. Nevertheless, treatment outcomes have improved due both to improvements in HIV medicine and in cancer therapeutics for the common lymphomas occurring in those with HIV infection. Other hematologic malignancies are rarely seen in HIV-infected patients, but the standardized risk ratio for many of these cancers is higher than in the background population. Principles of cancer care and appreciation for HIV infection as a comorbid condition can guide physicians in setting realistic goals and treatment for this patient population. In many cases, expected outcomes are very similar to the HIV-unrelated patients and therapeutic planning should be based on this understanding. Treatment tolerance can be predicted based on the status of the HIV disease and the cancer therapy being administered. For those hematologic cancers in which transplantation is part of standard care, this modality should be considered an option in those with HIV infection. Of huge importance is the Excess cancer and infection risk in the late 1970s and early 1980s relationship between the degree of CD4 cell depletion and heralded a new immunodeﬁciency syndrome now known as the type of lymphoma that develops. The advent of modern HIV therapeutics has revealed a spectrum of lymphomas that occur in patients with higher CD4 second act for HIV-related cancer and infection epidemiology. Indeed, this immunologic shift commonly occurring hematologic malignancies in HIV have consequent to widespread cART use most likely explains the improved. This article focuses on the role that combination survival improvement of HIV-related lymphomas in the cART antiretroviral therapy (cART) has played in this emerging era. The to the various hematological malignancies should be in the standardized incidence ratio (SIR) is 70 (145 if CD4 is 100; context of advanced HIV therapeutics. For example, The principal hematologic malignancies occurring with increased cHL occurs with relatively high frequency during the ﬁrst few frequency in association with HIV infection are lymphoid months after initiation of cART as the CD4 cell counts are neoplasms, principally lymphomas (Table 1). Therefore, all patients increasing and the HIV viral loads are decreasing, suggesting that cHL may be driven by immune recovery rather than by CD4 cell presenting with classical Hodgkin lymphoma (cHL), Burkitt lym- count depletion.

ICS/LABA for both maintenance and as-needed relief (ICS/LABA MART) vs. ICS/LABA for maintenance with a Short-Acting Beta-Agonist (SABA) for relief Summary of findings We found four fair or good quality RCTs (making five relevant comparisons) meeting our 98-100, 103-106 inclusion/exclusion criteria (Table 13). All compared the combination of budesonide (BUD) plus formoterol (FM) in a single inhaler for maintenance and as-needed relief with a fixed dose ICS/LABA combination plus a Short-Acting Beta-Agonist (SABA) for as-needed relief. BUD/FM is not approved for use as a relief medication in the United States, but it has been approved for maintenance and reliever therapy in Canada when administered via a DPI. Delivery of BUD/FM via pMDI is not indicated for MART. Two trials compared BUD/FM for 98-100, 103, 105 maintenance and relief to BUD/FM for maintenance with a SABA for relief; three trials compared BUD/FM for maintenance and relief to the combination of fluticasone and 98, 100, 104, 106 salmeterol (FP/SM) for maintenance with a SABA for relief. Several of the trials included in this section significantly reduced the total ICS doses for many of the subjects upon randomization (some studies averaged a 75% dose reduction). Overall, results from large trials up to twelve months in duration found statistically significantly lower odds of exacerbations requiring medical intervention for those treated with BUD/FM for maintenance and relief than for those treated with ICS/LABA for maintenance and a SABA for relief (moderate strength of evidence, Appendix H, Table H-6). A separate meta-analysis of exacerbations resulting in emergency department visits or hospital admissions revealed similar findings; the odds ratio for MART was 0. MART was also associated with fewer nocturnal awakenings, compared with 2 ICS/LABA + SABA (SMD = -0. I values for each of those meta-analyses were < 25%, indicating low heterogeneity, and sensitivity analysis results did not change our conclusions in either case. None of the individual trials found a significant difference in symptoms. Our meta-analyses found no statistically significant differences in symptom-free days (SMD = 0. Sensitivity analyses for each of these comparisons did not reveal anything that would change our conclusions. Detailed Assessment Description of Studies Of the four RCTs we included (Table 13), two compared BUD/FM MART to BUD/FM for 98-100, 103, 105 maintenance and SABA for relief, and three compared BUD/FM MART to FP/SM for maintenance and SABA for relief. All trials administered the ICS/LABA combinations in a 98, 100, 104 103, 105, 106 single inhaler. Controller medications for asthma 68 of 369 Final Update 1 Report Drug Effectiveness Review Project Total daily maintenance ICS components of the BUD/FM MART groups varied. One study compared low starting and mean ex-mouthpiece doses of BUD (in the MART arm) with 103, 105 low fixed-dose BUD (fixed-dose BUD/FM arm), one compared low mean daily dose of 98-100 BUD (MART arm) with medium and high doses of non-adjustable combinations, one 106 compared medium dose with medium dose, and one compared medium dose BUD (MART 104 arm) with high fixed-dose FP (FP/SM + SABA arm). In two studies, the mean total daily dose of ICS administered ex-mouthpiece in the BUD/FM MART group was less than the total daily 98-100, 104 dose in the ICS/LABA with a SABA for relief group. Several of the trials significantly reduced the total ICS doses for many of the subjects upon randomization. Some studies reduced the starting ICS doses to levels that could be considered inadequate compared to the subjects’ previous dose requirements. In three studies all medications were delivered via DPIs; one study 98-100 compared BUD/FM DPI with FP/SM pMDI. Study Populations The four head-to-head RCTs included a total of 10,547 subjects. Three studies were conducted in 105 adolescent and/or adult populations. One study included children and adults, and one 103 publication further described the subset of children four to 11 years of age from that study. All enrolled subjects that were not adequately controlled on 103-105 current therapy. Two were conducted in subjects with mild to moderate persistent asthma 98-100, 106 and two did not report asthma severity classification. Two trials did not report smoking 98-100, 104 rates and two allowed some smokers. Trials enrolling smokers reported that 4% to 7% of subjects in each group were current smokers. Sponsorship Of the four head-to-head trials, all four (100%) were funded by pharmaceutical companies. BUD/FM MART compared with ICS/LABA for maintenance and SABA for relief The results of the four RCTs contributing five comparisons (one study compared BUD/FM MART with BUD/FM maintenance and SABA relief and with FP/SM maintenance and SABA relief) are described below under the appropriate drug comparisons. Overall, all five comparisons reported statistically significantly lower rates of exacerbations for those treated with BUD/FM MART, but no differences in symptoms. We conducted meta-analyses for seven outcomes that were reported with sufficient data in multiple trials (Appendix I). These included symptom-free days, symptom scores, nocturnal awakenings, exacerbations requiring medical intervention, exacerbations resulting in emergency visit or hospital admission, rescue-free days, and rescue medicine use (puffs/day). Our meta-analysis for exacerbations requiring medical intervention shows an odds ratio of 0. A separate meta-analysis of exacerbations resulting in emergency department visits or hospital admissions revealed similar findings; the odds ratio for MART was 0. MART was also associated with fewer nocturnal awakenings, compared with ICS/LABA + SABA (SMD = - 2 0. We found no statistically significant differences in symptom-free days (SMD = 0. Of note, the comparisons that administered scheduled maintenance ICS doses that were lower in the BUD/FM MART group all found statistically significantly lower exacerbation rates 98-100, 104 for those treated with BUD/FM MART. In addition, the BUD/FM MART group had a lower mean daily steroid dose (maintenance plus relief) than the ICS/LABA for maintenance 98-100, 104, 106 with SABA relief in three of the five trials. Thus, it does not appear that delivering a higher total ICS dose explains the better exacerbations outcomes in the BUD/FM MART group. BUD/FM MART compared with BUD/FM for maintenance and SABA for relief 98-100 103, 105 We found one good- and one fair-quality RCT for this comparison. Both trials reported asthma symptoms, nocturnal awakenings, exacerbations, and rescue medicine use 98-100 (Table 13). One trial also reported missed work, hospitalizations, and emergency visits (Evidence Tables A and B). The results are mixed but show a trend favoring the BUD/FM MART for several outcomes. Both reported statistically significant differences in exacerbations favoring BUD/FM MART, but reported no difference in symptoms. One trial reported fewer 103, 105 nocturnal awakenings in both children and adults treated with BUD/FM MART. The single study reporting hospitalizations and emergency visits found no difference between groups in the 98, 99 full population analysis but a small but significant decrease in hospitalizations / emergency 100 visits favoring BUD/FM MART among those age 16 and older. The trial reporting missed work found a numerical difference favoring BUD/FM MART, but the statistical significance was 98-100 not reported. None of the trials reported any outcomes favoring the BUD/FM for maintenance and SABA for relief. BUD/FM MART compared with FP/SM for maintenance and SABA for relief 98-100, 104 106 We found two good- and one fair-quality RCTs comparing these treatments. All three trials reported asthma symptoms, exacerbations, and rescue medicine use (Evidence Tables A 98-100, and B). Two trials reported nocturnal awakenings and hospitalizations or emergency visits. The results are mixed but show a trend favoring BUD/FM MART for some outcomes.

No studies of carvedilol phosphate (extended-release carvedilol) in patients with severe heart failure were identified. Atrial arrhythmia Overall grade: Fair Bisoprolol equivalent to carvedilol in preventing relapse of atrial fibrillation in a head-to-head trial. Metoprolol succinate reduced incidence of atrial arrhythmia/fibrillation in a placebo-controlled trial.

Migraine Overall grade: Fair Atenolol, slow release metoprolol, immediate release metoprolol, and timolol were all similar to propranolol in their effects on pain outcomes and acute medication use in 5 head-to-head trials. No significant differences were found between nebivolol and metoprolol on frequency of migraine attacks and severity. Bleeding esophageal varices Overall grade: Poor Results of 1 head-to-head trial of atenolol and propranolol, 1 placebo-controlled trial of nadolol, and 6 placebo-controlled trials of immediate release and 2 formulations of extended release propranolol, all fair quality, didn’t clearly differentiate one beta blocker from another. Adverse effects Hypertension, stable angina, Overall grade: Fair A few differences in specific adverse event rates were heart failure, atrial arrhythmia, noted across longer-term trials directly comparing one migraine, bleeding esophageal beta blocker to another. Demographics (age, gender, Overall grade: Fair Evidence showed that age, gender, and race did not race) impact the effectiveness of carvedilol, immediate and controlled release metoprolol, and propranolol. There was insufficient evidence on the effect of beta blockers on perinatal mortality or preterm birth based on 1 systematic review. High risk populations Overall grade: Fair Heart failure. Subgroup analyses of placebo-controlled trials showed that a history of myocardial infarction may reduce the protective effect of bisoprolol on mortality (CIBIS). No risk factor was found to confound the protective effect of carvedilol (COPERNICUS) or controlled release metoprolol (MERIT-HF) on mortality. The MIAMI trial found that metoprolol had the greatest protective effect on mortality in patients with numerous risk factors. The BHAT trial found no variation in propranolol’s protective effect on total mortality based on history of heart failure. Subgroup analysis of the SHEP trial found that the addition of atenolol to chlorthalidone did not significantly affect mortality relative to placebo. Metoprolol use reduced all-cause mortality and hospitalizations relative to placebo in a subgroup analysis of the MERIT-HF trial. Abbreviations: NYHA, New York Heart Association classification.

Another trial reported a trend in E2 groups towards increased bone density, however statistical 126 significance was not reached for between group comparisons. All 15 trials of transdermal E2 reported statistically significant improvements in bone 127-139 density compared to placebo. Only three trials did not use concomitant 129, 134, 138, 140, 141 progestin/progesterone. Five trials of E2V with concomitant progestin/progesterone reported bone density 111, 142-145 outcomes. Four of the five trials noted improvement in treatment groups compared to 111, 142-144 145 placebo, and one did not. All trials reported significant within-group changes in bone density at multiple sites for various doses with higher doses showing greater changes. In a good-quality trial comparing combination treatment with CEE (with or without medroxyprogesterone) plus alendronate to either treatment alone, patients on combination therapy had a significantly greater increase in total hip BMD than those 170, 171 151 on either ALN or HRT alone after 3 years (p<. A more recent substudy of the Women’s HOPE trial found that most women on lower doses of CE with or without medroxyprogesterone (0. Similar improvements were found in the lumbar spine. In subjects with 6-year follow-up BMD data (n=443), the percentage increase in lumbar spine BMD was 7. The CEE-only study of the WHI produced modest but consistent positive effects on bone 173 mineral density. Hormone therapy Page 46 of 110 Final Report Update 3 Drug Effectiveness Review Project 174 One study of esterified estrogen examined dosages of 0. Effect of discontinuation of estrogen on bone density Two studies reported the effect on bone density after discontinuing the use of estrogen to determine if bone density gains were sustained after discontinuation, or if there was evidence that bone loss was accelerated in women who had used estrogen therapy when compared with 175, 176 those who had not used it. Both studies found the rate of bone loss after stopping estrogen was similar to that of women who did not receive estrogen treatment, as described below. Further bone density gains were not observed in women after discontinuation of estrogen therapy, but there was also no evidence of accelerated bone loss when compared with those who had taken placebo. The second study reported the effect on bone mineral density of discontinuation of estrogen therapy for one year after 5 years of treatment in women enrolled in a randomized placebo-controlled trial of raloxifene and estrogen for 176 prevention of postmenopausal bone loss. This study also found that changes in bone density after one year of discontinuation were not significantly different in women using CEE compared with women randomized to placebo. Comparison with other meta-analyses A Cochrane review and meta-analysis published in 2002 on estrogen and bone density 7 and fractures was reviewed for this report. Fifteen of the trials included in the Cochrane review did not meet inclusion criteria for this review because they used ineligible estrogen 177-191 preparations. Results of the Cochrane meta-analysis included: • The pooled percent change in bone density was statistically significantly increased with estrogen compared to placebo at all measurement sites when combining results for all prevention and treatment trials and for both opposed and unopposed regimens. Hormone therapy Page 47 of 110 Final Report Update 3 Drug Effectiveness Review Project o For high-dose estrogen (equivalent to 0. For the lumbar spine, the differences between estrogen and placebo groups were: o 5. This study was restricted to placebo-controlled trials of at least 2 year’s duration and enrollment of at least 60 subjects. Although the study did not report a systematic assessment of the quality of the trials selected for review, the number of dropouts in each trial and use of intention-to-treat results were assessed. The 2-year mean changes in lumbar spine BMD (weighted for the ratio of sample size/dropouts) are summarized as follows: o 7. Fractures Head-to-head comparisons No head-to-head trials were found. Placebo comparisons We identified 11 studies of estrogen that included outcome data on fractures (Evidence 128, 135, 144, 155, 156, 168, 193 7 Table 6). Seven were included in a recent Cochrane meta-analysis, and 4, 117, 149, 194 the remainder were more recently published. Only one study of oral E2 evaluated fracture outcomes and found a statistically significant risk reduction for forearm fractures (RR=0. Both studies of transdermal E2 indicated no 128, 135 128 significant improvement in vertebral and non-vertebral fractures. One trial of E2V in early postmenopausal women reported a significant decrease in nonvertebral (RR=0. Although some of these studies showed a trend toward reduction of fractures at various sites in the treatment groups, only 4 the WHI showed a significant result. When compared with the placebo group, total fractures for 4 women on CEE were significantly reduced (HR=0. Risks were also reduced for site-specific fractures of the hip and vertebra, although confidence intervals adjusted for multiple comparisons included 1. This effect did not differ in women stratified by age, body mass index, smoking status, history of falls, personal and family history of fracture, total calcium intake, past use of hormone therapy, bone density, or summary fracture risk score. Hip fractures and clinical vertebral fractures were also decreased, although 95% confidence intervals adjusted for multiple comparisons overlapped a HR of 1. Additional data on fractures recorded 173 through the study termination (average 7. These positive effects occurred largely irrespective of baseline risk factors for osteoporosis or fracture. The global index of overall health risks and benefits was balanced, however, with no evidence of overall benefit or risk noted even for women in the highest tertile of risk for fracture. Comparison with Cochrane meta-analysis 128, 135, 144, 155, 156, 168, 193 Seven studies reporting fracture outcomes were included in a 7 Cochrane review published in 2002. Two trials indicating significant fracture risk reduction, including the WHI, were not included because they were published after the Cochrane 117 analysis. Findings included: • Four of five studies measuring vertebral fracture outcomes indicated non-statistically 131, 151 ,164, significant reductions in estrogen groups (RR=0. What is the comparative safety of different hormone therapy preparations for short-term use (<5 years)? Summary points - Breast tenderness and vaginal bleeding increase with all estrogen preparations. Hormone therapy Page 49 of 110 Final Report Update 3 Drug Effectiveness Review Project - All of the trials of symptoms and most of the trials of bone density and fractures were less than 5 years in duration and few enrolled more than 200 participants. Head-to-head trials Adverse events reported in short-term head-to-head trials of different estrogen preparations are shown in Evidence Tables 7 (trials with symptom outcomes) and 8 (trials with bone outcomes). Head-to-head comparison trials provided insufficient evidence to determine the relative adverse effects of different estrogens. One trial of CEE and oral E2 reported that the incidence of possible drug-related adverse experiences ranged from 20% in placebo, E2 1 mg/day, and CEE 0. Most head-to-head trials reported similar rates of specific adverse events and withdrawals due to adverse events between treatment groups, with a few exceptions. In one trial, a significantly greater incidence of breast tenderness was found in women randomized to oral E2 2 mg plus NETA versus CE 5 mg plus MPA, and more women in the E2/NETA group withdrew 19 from the trial during the first 3 months (17. A trial of a vaginal ring releasing E2 compared with an E2 vaginal tablet found more withdrawals in the vaginal ring group, mainly occurring during the first 3 months of treatment and due to abdominal discomfort, 25 lower back pain, and slippage of the ring. In a head-to-head trial of an intravaginal ring delivering E2 compared with oral E2 for treatment of vasomotor symptoms, there were no 24 significant differences between groups in the frequency of the most common adverse events. Placebo-controlled trials Withdrawals due to adverse effects and withdrawals due to specific adverse effects in placebo controlled trials are summarized in Evidence Table 9 for trials of hot flashes and Evidence Table 10 for trials of bone density and fractures.

Glatiramer was more effective than placebo in relapse rate based on 3 small fair-quality trials but no difference on the percentage relapse free. The evidence on the effect of glatiramer on disease progression is inconclusive based on data from 1 trial. Natalizumab and mitoxantrone were more effective than placebo for relapse-related and disease progression outcomes in placebo-controlled trials. Evidence was based on a small number of trials (2 for natalizumab and 1 for mitoxantrone). Secondary progressive multiple sclerosis • There is no direct evidence. Evidence from placebo- controlled trials showed that the all of β interferons were similarly effective at reducing relapse rates. A positive effect on disease progression was observed with ® interferon β-1b (Betaseron ) although similar effects were not consistently observed with the interferon β-1a products. Primary progressive multiple sclerosis • The only evidence available (from 1 small, good quality ® trial comparing interferon β-1a IM (Avonex ) to placebo) is insufficient to make any judgments regarding effectiveness in PPMS patients.

Serious adverse events NAbs: The clinical impact of the presence of neutralizing antibodies is unclear although limited data suggests they may negatively impact relapse rate after 3-4 years of treatment. Liver function: ALT elevations are common with all β interferon products, with little difference in rates of occurrence. Thyroid function: Limited data from 2 observational studies found similar rates of clinical and subclinical thyroid autoimmunity with ® Interferon β-1a IM (Avonex ) and Interferon β-1b SC ® (Betaseron ) Depression: There was a lower rate of depression in patients ® taking interferon β-1a (Rebif ) compared with the other interferons based on limited trial data. One small observational study comparing β interferons and glatiramer also found no differences in depression rates, although our own analysis of the all published trials reporting rates of depression indicates an increase in risk for all interferon β1 products. Cancer: Data from 1 cohort study found a potentially increased risk of cancer development in women with either β interferon or glatiramer acetate use; these results are inconclusive. Therapy- related acute leukemia was reported in 2/1620 patients taking mitoxantrone.

Tolerability ® Flu-like syndrome: Interferon β-1a IM (Avonex ) was associated with the highest rates of flu-like syndrome compared with the other β interferons (~62% compared with 28%). Systemic reactions: Post-injection systemic reactions were observed in patients receiving glatiramer acetate, although these were usually limited to a single episode. There were no events reported of this outcome in trials of β interferons, natalizumab or mitoxantrone. Long-term safety in observational studies Long-term safety data from comparative and non-comparative, non-randomized studies was consistent with that reported in trials. Significant concerns include progressive multifocal leukoencephalopathy in patients receiving natalizumab >12 months, lipoatrophy with prolonged use of glatiramer and permanent amenorrhea in older women receiving higher total dose of mitoxantrone.

Approximately 60% of patients were on more than 1 oral hypoglycemic agent, while 30% were on more than 2 oral agents (Table 13). Patients were considered to have “failed” therapy with metformin, pioglitazone, or glimepiride at screening or after 10-19 weeks of dose stabilization and if HbA1c was between 7% and 10% or 7. Patients also entered 2-week single-blind, placebo run-in periods prior to randomization. The addition of sitagliptin to metformin, pioglitazone, or glimepiride appears to show larger reductions in HbA1c and compared with the addition of placebo over 18 to 30 weeks (Table 16). Subjects who received placebo plus glimepiride showed worsening glycemic control, while subjects on placebo plus metformin or placebo plus pioglitazone had slight improvements or no change in HbA1c from baseline. Weight gain was generally seen in patients taking sitagliptin in combination with pioglitazone or glimepiride to a similar extent of those taking pioglitazone alone, however no weight gain was seen in those taking glimepiride alone. Patients randomized to add sitagliptin or placebo to metformin lost weight by 0. Pooled analysis was not conducted due to small number of studies and significant heterogeneity. Unlike the other studies , this trial evaluated the effects of sitagliptin in patients with worse glycemic control (baseline HbA1c between 8% and 11%). These patients were on metformin and diet and exercise for 6 weeks, had baseline HbA1c between 8% and 11%, and had ≥85% adherence to their regimens during a 2-week, placebo run- in period. No patients were naïve to oral hypoglycemic agents and approximately 50% were already taking metformin monotherapy or combination oral therapy at baseline. The addition of sitagliptin to ongoing metformin therapy was more effective than placebo plus metformin at lowering HbA1c (placebo-corrected difference: −1. One study was unique in that it included patients who were inadequately controlled on 51 insulin and/or metformin therapy. Patients were randomized to sitagliptin 100 mg or placebo in addition to their pre-study doses insulin and metformin (if they were taking). Approximately 70% of patients in both groups were taking metformin at baseline. Doses of insulin and metformin were not increased, however insulin could be decreased if hypoglycemia occurred. Similar results were seen in this study as others, with greater HbA1c lowering seen in patients randomized to sitagliptin than placebo (difference in LS mean change −0. Authors reported no difference in HbA1c lowering in patients on metformin or not on metformin (p=0.

Summary of Findings for Saxagliptin Evidence in children • We found no studies including children and adolescents ≤ 18 years Evidence in adults • All studies focused on intermediate outcomes with none focusing on health outcomes as primary outcomes. Some studies reported some health outcomes such as all-cause mortality or cardiac death among secondary outcomes or adverse events. Overall evidence was insufficient to determine how saxagliptin compares with other treatments for their impact on health outcomes. Detailed Assessment for Saxagliptin Randomized controlled trials We found 5 fair-quality randomized placebo-controlled trials meeting our inclusion/exclusion criteria. This section is organized by how saxagliptin was used (monotherapy or add-on therapy). There were no active control studies identified that met inclusion criteria. Characteristics of included studies are shown in Table 18.

Monotherapy: Saxagliptin compared with placebo In 2 fair-quality randomized controlled trials carried out over 12-24 weeks, a wide variety of 53, 54 doses were compared to placebo. Data abstracted was for approved doses in the United States, Saxagliptin 2. All patients included in the trials were treatment naïve and mean baseline HbA1c for participants ranged from 7. Overall, reduction in HbA1c was greater with saxagliptin compared to placebo and slightly greater with saxagliptin 5 mg compared to 2. There was a 53 numerically greater HbA1c reduction with saxagliptin in the 12 week trial compared to the 24 54 week trial, however the placebo corrected change was similar between the two trials. Patients were similar between the 2 trials except patients in the 24 week trial had diabetes for longer than those in the 12 week trial (mean duration 2. Weight loss was seen across all groups, however more weight loss was seen in the placebo group than in either saxagliptin 2. Patients randomized to saxagliptin 5 mg had less weight loss than those randomized to saxagliptin 2.

Add-on therapy: Saxagliptin or placebo added to one oral hypoglycemic agent Three fair-quality trials were identified that compared saxagliptin to placebo as add-on therapy in patients not achieving adequate glycemic control on either metformin, a thiazolidinedione, or 55-57 glyburide. Patients were deemed to have inadequate glycemic control if their HbA1c was ≥7% to ≤10% or ≥7% to ≤10. In general, the addition of saxagliptin to metformin, a thiazolidinedione, or glyburide appears to show larger reductions in HbA1c compared with the addition of placebo over 24 weeks (Table 20). Results were not stratified by which thiazolidinedione patients were taking. Varying results were seen in regards to change in weight. The addition of placebo to glyburide or a thiazolidinedione resulted in less weight gain than the addition of saxagliptin to glyburide or a thiazolidinedione. Slightly more weight loss was seen with the addition of saxagliptin 2. No statistical testing was done to determine the statistical significance of these differences. One study randomized patients who had inadequate glycemic control on submaximal 57 doses of sulfonylurea therapy. Patients were switched from their current sulfonylurea to open label glyburide 7. After a 4 week single blind run-in period, patients continued their open label glyburide and were randomized to either saxagliptin 2. Therefore patients randomized to placebo had a total daily dose of glyburide 10 mg daily as compared with glyburide 7.
