Therefore, in yet to be rigorously established and signiﬁcant scientiﬁc challenges the near future, stem cell–based therapy strategies for hemophilia A remain. However, despite these deﬁciencies, several clinical trials and B likely will remain dependent on gene transfer technology. Following up on these ﬁndings, limiting and the primary determinants of this limitation are believed Oshimura et al genetically modiﬁed iPSCs derived from embryonic to be speciﬁc amino acid sequences within the molecule itself. For example, it was shown by Kaufman et al that h-FVIII mRNA expression was detected in the resulting cells. Nathwani et al combined a similar approach with codon optimiza- MSCs are an ideal cellular vehicle for the delivery of nucleic tion and demonstrated signiﬁcant improvement in FVIII production acid–based therapeutics due to their ease of harvest, robust cell from liver-directed AAV gene transfer systems. How- differential occurs through reduced engagement of the unfolded ever, because MSCs have not been demonstrated in vivo to protein response pathway,10 and have used this information to regenerate or maintain a tissue compartment and thus do not meet generate humanized, human/porcine (HP) high-expression FVIII the strict deﬁnition of a stem cell, they also can be termed constructs that retain this biosynthetic advantage. Currently, MSCs are the subject of 500 strategy is being pursued in gene therapy applications for hemo- clinical trials for a wide array of medical conditions including, but philia B through the use of a naturally occurring human FIX variant not limited to, osteogenesis imperfecta, Crohn’s disease and ulcer- termed FIX-Padua (R338L) that exhibits greater speciﬁc procoagu- ative colitis, multiple sclerosis, diabetes, liver cirrhosis, and knee lant activity than wild-type human FIX. Inclusion of this modiﬁed cartilage injury, which as suggested by Ebihara et al, may be applicable to hemophilic joint arthropathy. However, the safety and transfer appears to be a necessary component for the clinical efﬁcacy of these molecules remain to be tested and proven in utilization of MSCs toward correction of bleeding in hemophilia. Several groups of investigators are pursuing this approach and, of these, one particularly promising but preliminary study was con- ducted in an ovine model of hemophilia A. Genetically modiﬁed MSCs were trans- ongoing clinical trials of hESC-derived products and all except 1 planted into the peritoneal cavity of 2 affected hemophilia A target macular degeneration (acute wet age-related, Stargard’s, and recipients, the ﬁrst of which already harbored a low-titer inhibitor against h-FVIIII and received a dose of 3 107 cells. The second advanced dry age) and are sponsored by Advanced Cell Technol- ogy. The remaining trial, sponsored by Assistance Publique– did not yet possess an inhibitor and received an initial dose of 1. Before transplantation, both animals presented with Hopitaux de Paris, involves the testing of CD15 Isl-1 hESC- derived progenitors in ischemic heart disease. At present, no bleeding episodes and progressive morbidity despite receiving ongoing clinical PSC approaches appear prototypical for application on-demand therapy with h-FVIII products. After stem cell therapy, to hemophilia, but more research and development in this area chronic joint arthropathy resolved in both animals and they re- appear warranted. Toward this goal, several research groups re- mained bleeding episode free for 2 months in the absence of FVIII cently reported on the feasibility of PSC therapy for hemophilia. Both animals developed high-titer anti-p-FVIII inhibitors example, Xu et al generated iPSCs from tail tip ﬁbroblasts of that cross-reacted with and negated the efﬁcacy of h-FVIII products. Despite this immune reaction, the animals did not bleed transection assay. Ohmori et al also investigated the therapeutic for an extended period of time. It was speculated that the phenotypic potential of murine iPSCs, although SIV-based lentivector gene correction resulted from the widespread distribution of genetically transfer of a BDD h-FVIII transgene was used to enhance, if not modiﬁed MSCs that likely homed to sites of joint injury and provide the sole source of, FVIII. Unfortunately, both animals eventu- dubbed “molecular chimerism. Notwithstanding their pre- of a single new molecular antigen (ie, FVIII) and the low-level mature deaths, these hemophilic sheep represent impressive case (micro) chimerism that is achievable using reduced toxicity condi- studies that may predict the clinical utility of genetically modiﬁed tioning regimens. Immune nonresponsiveness or even tolerance MSCs in hemophilia both with and without preexisting FVIII induction is a critical requirement of cell and gene therapy immunity. Current preclinical research in the ﬁeld of A current challenge to the development of MSC-based therapeutics HSCT gene therapy of hemophilia is focused on 4 main issues. To address The ﬁrst, as mentioned earlier, is the general understanding of these obstacles, Hortelano et al have been investigating the ability of lentivector integration proﬁles and risk of insertional mutagen- different biomaterials to improve cord blood–derived MSC viabil- esis. The third is both arginine-glycine-aspartate (RGD) and ﬁbrinogen-coated alg- the development of protocols and agents designed to minimize inate-PLL microcapsules improve cell survival over noncoated transplantation conditioning regimen-related toxicity while main- microcapsules. However, only ﬁbrinogen-coated microcapsules taining sufﬁcient and durable HSC engraftment. Similarly, Galipeau et al demonstrated that overcoming the hurdle of preexisting immunity to FVIII or FIX. FVIII deﬁciency was not achieved, the study did provide evidence for immune tolerance, or at least nonresponsiveness, induction. Multipotent adult stem cell therapies: HSCs Furthermore, it demonstrated the difﬁculties associated with the HSCs are an ideal target for life-long expression of therapeutic development of gene therapy applications for hemophilia A by the proteins because BM transplantation studies in children have shown inefﬁciency of FVIII biosynthesis. The ﬁrst preclinical HSCT gene that transplanted HSCs survive for the lifetime of the recipient.
The head-to- head trials allowed inclusion of patients with comorbidities other than renal rivastigimine 3 mg visa, hepatic cheap rivastigimine 4.5 mg line, and psychiatric illnesses purchase rivastigimine 1.5mg fast delivery, and some allowed a broader range of comorbidity rivastigimine 3 mg lowest price, but none of the trials analyzed the effect of comorbidity on efficacy or adverse events in a comparative way cheap rivastigimine 4.5mg amex. One 38 study reported that coexisting illness was significantly associated with withdrawal from the study but did not stratify by drug. This study randomized patients to a 2-week treatment of oxybutynin immediate-release 5 mg 3 times daily or trospium 20 mg twice daily with a placebo at midday. The overall rate of side effects including dry mouth was similar in the two groups. Severity of dry mouth was graded on a 4-point scale. Overactive bladder Page 41 of 73 Final Report Update 4 Drug Effectiveness Review Project Withdrawal occurred more commonly with oxybutynin immediate-release (16%) than trospium (4%). There were differences in demographic and urodynamic variables between the 2 groups at baseline and the numbers of randomized patients were unbalanced (more in one group than the other). While small differences in the number of patients randomized to each group is to be expected, large differences indicate a problem with the randomization process. Type or level of spinal cord injury was not provided, nor was information about other medications. Summary of the evidence Key question Quality of body of Findings a evidence Key question 1: Comparative efficacy In head-to-head trials what is the Oxy IR vs Tol IR: Fair Four studies of Oxy IR vs Tol IR found no comparative efficacy of Tros IR vs Oxy IR: Fair difference in efficacy. One study of Tros IR vs anticholinergic incontinence Tros IR vs Oxy ER: Fair Oxy IR found no difference in efficacy. Tros ER vs Oxy ER: results were found with Oxy ER vs Tol ER; the Poor better study found them equal. Flav: Poor Sol showed greater efficacy over Tol (IR and ER) Sol vs Tol IR: Fair for some outcomes in 2 short-term studies. No Sol vs Tol ER: Fair difference in efficacy found between Dar and Dar vs Oxy IR: Fair Oxy IR. What is the comparative efficacy Fair Four studies of Oxy ER vs Oxy IR and 1 of Tol of long-acting vs short-acting ER vs Tol IR found no difference in efficacy. One anticholinergic incontinence study of Oxy ER vs Tol IR found Oxy superior, drugs? Key question 2: Adverse events Long-term studies: Poor One comparative study assessing the discontinuation rate of Tol and Oxy over a 6- month period found a higher rate and earlier withdrawal with Oxy, but rates for both drugs were high. Uncontrolled studies reported dry mouth as the most common adverse event and found similar rates of adverse events and withdrawals between the drugs. Short-term studies: Fair Head-to-head trials indicate a higher incidence of adverse events overall and specifically dry mouth with Oxy. The ER form had less frequent adverse events overall and, specifically, less dry mouth than the IR form. Tros less often causes severe dry mouth than Oxy, although overall incidence of dry mouth and short-term adverse events are similar to those of Oxy IR. A Sol vs Tol ER trial found a lower rate of dry mouth for Tol ER. The difference between drugs based on withdrawals is less clear: 2 Sol vs Tol trials found similar rates of adverse events overall. What is the difference in adverse Tol IR vs Tol ER: Fair A short-term head-to-head comparison of Tol IR events between long-acting and Oxy IR vs Oxy ER: Fair vs Tol ER found a higher rate of dry mouth with short-acting formulations of the IR form. Withdrawal due to adverse event anticholinergic incontinence was similar for both. Short-term head-to-head comparison of Oxy IR vs Oxy ER found a higher rate of dry mouth with the IR form. Withdrawal due to adverse event was similar for both. Overactive bladder Page 42 of 73 Final Report Update 4 Drug Effectiveness Review Project Key question Quality of body of Findings a evidence Key question 3: Subpopulations Gender: Poor Evidence limited to 5 studies was not consistent (inconsistent) in identifying differences between men and Age: Fair women in response to tolterodine. Older patients Racial groups: Fair were found to respond to Oxy, Tol ER, Comorbidity: Fair darifenacin or solifenacin in post-hoc subgroup analyses. Adverse event profiles were similar to those found in the overall trial populations. Oxy IR and Tol IR resulted in similar response and adverse event rates in Chinese women compared to other studies with primarily White populations. Solifenacin was found to have similar response and adverse event rates in a Hispanic subgroup compared to the overall trial population in one study. Tol ER and Tol IR were found to be similarly effective in Japanese and Korean women, with fewer adverse events in the Tol ER group. The Japanese patients were shown to have improved quality of life in both groups, no such analysis was undertaken for the Korean patients. Two studies of men taking an alpha antagonist for symptoms associated with benign prostatic hypertrophy with residual symptoms of overactive bladder found that adding Tol ER resulted in significant improvement in symptoms related to both overactive bladder and benign prostatic hypertrophy compared to Tol ER, placebo or an alpha antagonist alone. Patient Perception of Bladder Condition was not improved in one study.
Pramlintide: Applicability to General Populations with Type 2 Diabetes No included trial evaluated the effects of pramlintide in patients whose type 2 diabetes was inadequately managed on combination prandial and basal insulin therapy with or without oral agents purchase rivastigimine 6mg without prescription. Two studies evaluated pramlintide in patients using fixed-dose insulin purchase rivastigimine 3mg line. One trial used flexible dosing for insulin glargine only and 1 compared pramlintide with flexible rapid acting insulin analog (RAIA; lispro safe 3 mg rivastigimine, aspart discount rivastigimine 1.5 mg mastercard, or glulisine) in addition to flexible basal insulin (glargine or 22 detemir) order rivastigimine 6 mg without prescription. Hence, results have limited applicability to the broader population using more commonly prescribed insulin regimens. US Food and Drug Administration-approved dosage of pramlintide for type 2 diabetes includes initial therapy of 60 mcg/meal and maintenance therapy of 120 mcg/meal. Three trials 22, 24, 25 examined the 120 mcg dosage. The third included trial was a dose-ranging study that did 26 not use a 120 mcg dose but did include a 75 mcg dose which may be used in clinical practice. Overall, patients included in these 3 trials represent a highly selected population: mainly white, middle-aged men and women with mean baseline HbA1c between 8. None of the patients had significant pulmonary, cardiovascular, renal, neurologic, or hematologic diseases or problems with gastrointestinal motility. The study populations probably included highly motivated subjects who desired to achieve optimal glycemic control through the additional 2-4 injections added to their usual regimens of insulin and oral hypoglycemic agent over 16-52 weeks of participation in a trial. Study setting also was not reported in any of the included trials; subjects likely were evaluated in outpatient clinics. Sitagliptin and Saxagliptin: Applicability to General Diabetes Populations Patients enrolled in the sitagliptin and saxagliptin trials represented a highly selected population: primarily white, middle-aged, obese adults with moderately elevated baseline HbA1c (< 9%) and diabetes for less than 10 years. These populations were further selected during long dose- stabilization and run-in periods, where only persons with > 75% adherence to placebo went on to randomization. Moreover, these trials did not provide much baseline information on comorbidities and other characteristics and laboratory values that would enable inference about the applicability of study findings to general diabetic populations. The available data appear to be limited to persons with diabetes without related comorbidities and who are highly motivated. Exenatide: Applicability to General Diabetes Populations The studies identified for this review are rather homogeneous, relatively small, and may be rather selected, thus applicability to broader diabetes populations may be limited. Study subjects were homogeneous across studies for age, sex, and baseline HbA1c in both the placebo- and active- control trials. Significant comorbidities were excluded in placebo-controlled studies reporting 69-71 62, that characteristic and comorbidities were not mentioned in 3 of the 4 active-control trials. In other words, the number of potential study subjects who did not tolerate twice daily injections and who were therefore not included in the study was usually not reported. Open label extension studies were of highly selected populations who completed the primary study and who volunteered to continue (or start if on placebo) exenatide. Liraglutide: Applicability to General Diabetes Populations The studies identified for this review are rather homogeneous, relatively small, and may be rather selected, thus applicability to broader diabetes populations may be limited. Study subjects were homogeneous across studies for age, sex, duration of diabetes, and baseline HbA1c in both the placebo- and active-control trials. Significant comorbidities were excluded in the placebo- controlled studies reporting that characteristic. Studies Currently Being Conducted We identified no trials in progress that would meet inclusion criteria for this review that would potentially change conclusions.
