Orally Delivered Stimulus-Sensitive Nanomedicine to Harness Teduglutide Efficacy in Inflammatory Bowel Disease.

Inflammatory Bowel Disease (IBD) is a chronic inflammatory condition affecting the gastrointestinal tract (GIT). Glucagon-like peptide-2 (GLP-2) analogs possess high potential in the treatment of IBD by enhancing intestinal repair and attenuating inflammation. Due to the enzymatic degradation and poor intestinal absorption, GLP-2 analogs are administered parenterally, which leads to poor patient compliance. This work aims to develop IBD-targeted nanoparticles (NPs) for the oral delivery of the GLP-2 analog, Teduglutide (TED). Leveraging the overproduction of Reactive Oxygen Species (ROS) in the IBD environment, ROS-sensitive NPs are developed to target the intestinal epithelium, bypassing the mucus barrier. PEGylation of NPs facilitates mucus transposition, but subsequent PEG removal is crucial for cellular internalization. This de-PEGylation is possible by including a ROS-sensitive thioketal linker within the system. ROS-sensitive NPs are established, with the ability to fully de-PEGylate via ROS-mediated cleavage. Encapsulation of TED into NPs resulted in the absence of absorption in 3D in vitro models, potentially promoting a localized action, and avoiding adverse effects due to systemic absorption. Upon oral administration to colitis-induced mice, ROS-sensitive NPs are located in the colon, displaying healing capacity and reducing inflammation. Cleavable PEGylated NPs demonstrate effective potential in managing IBD symptoms and modulating the disease's progression.

The Impact of Teduglutide on Real-Life Health Care Costs in Children with Short Bowel Syndrome.

OBJECTIVES: To analyze the real-life health care costs of home parenteral nutrition (HPN) in children with short bowel syndrome with intestinal failure (SBS-IF) before and after treatment with teduglutide, and to compare those with costs of children with SBS-IF not treated with teduglutide. STUDY DESIGN: All consecutive children with SBS-IF on HPN treated with subcutaneous teduglutide starting from 2018 through 2020 in a tertiary French referral center were retrospectively included. These patients were matched to children with SBS-IF on HPN followed during the same 3-year period who were eligible for the teduglutide but were not treated. HPN direct medical costs included home-care charges, HPN bags, hospital admissions, and teduglutide. A comparison of costs before/after treatment and between patients treated/not treated was performed. RESULTS: Sixty children were included: 30 (50%) were treated with teduglutide and 30 (50%) were untreated. In the treated group, the median total costs of HPN significantly decreased after 1 (P < .001) and 2 years of treatment (P < .001) from 59 454 euros/year/patient to 43 885 euros/year/patient and 34 973 euros/year/patient, respectively. When we compared patients treated and not treated, the total HPN costs/year/patient were similar at baseline (P = .6) but were significantly lower in the teduglutide-treated group after 1 (P = .006) and 2 years of treatment (P < .001). When we added the cost of teduglutide into the analysis, the total cost increased significantly in the treated group and remained much greater even after modeling a reduction in the cost of the drug to one-third the present cost and PN weaning (P < .001). CONCLUSIONS: Treatment with teduglutide is associated with a significant reduction in the annual costs of HPN but still remains expensive because of the drug itself. Finding cost-saving strategies is essential.

Emerging drugs for the treatment of short bowel syndrome.

INTRODUCTION: SBS is a rare and disabling condition. The standard management is based on diet optimization with parenteral supplementation. In addition, glucagon-like peptide-2 (GLP-2)analogs, have shown promising results as disease-modifying therapies for SBS. AREAS COVERED: Short bowel syndrome (SBS) is defined as a reduction in functional intestinal length to less than 200 cm, leading to intestinal failure (IF) leading to malnutrition and parenteral support dependency. This review discusses the current management of SBS-CIFpatients, the place of GLP-2 analog treatment in terms of efficacy, safety and availability, and the new perspectives opened by the use of enterohormones. EXPERT OPINION: Clinical trials and real-world experience demonstrated that Teduglutide   reduces dependence on parenteral support and has a place in the management of patients with SBS-CIF.  The use of Teduglutide should be discussed in patients stabilized after resection and its introduction requires the advice of an expert center capable of assessing the benefit-risk ratio. The complex, individualized management of SBS-C IF requires theexpertise of a specialized IF center which a multidisciplinary approach. The arrival of new treatments will call for new therapeutic strategies, and the question of how to introduce and monitor them will represent a new therapeutic challenge.

Early use of teduglutide in paediatric patients with intestinal failure is associated with a greater response rate: a multicenter study.

Teduglutide is a glucagon-like-peptide-2 analogue that reduces the need for parenteral support in patients with short bowel syndrome (SBS). Nevertheless, data about long-term therapy with teduglutide in children are still scarce. Our objective was to describe the real-life experience with teduglutide in children with SBS over the last 5 years in Spain. This was a national multicentre and prospective study of paediatric patients with intestinal failure (IF) treated with teduglutide for at least 3 months. The data included demographic characteristics, medical background, anthropometric data, laboratory assessments, adverse events, and parenteral nutrition (PN) requirements. Treatment response was defined as a > 20% reduction in the PN requirement. The data were collected from the Research Electronic Data Capture (REDCap) database. Thirty-one patients from seven centres were included; the median age at the beginning of the treatment was 2.3 (interquartile range (IQR) 1.4-4.4) years; and 65% of the patients were males. The most frequent cause of IF was SBS (94%). The most common cause of SBS was necrotizing enterocolitis (35%). The median residual bowel length was 29 (IQR 12-40) cm. The median duration of teduglutide therapy was 19 (IQR 12-36) months, with 23 patients (74%) treated for > 1 year and 9 treated for > 3 years. The response to treatment was analysed in 30 patients. Twenty-four patients (80%) had a reduction in their weekly PN energy > 20% and 23 patients (77%) had a reduction in their weekly PN volume > 20%. Among the responders, 9 patients (29%) were weaned off PN, with a median treatment duration of 6 (IQR 4.5-22) months. The only statistically significant finding demonstrated an association between a > 20% reduction in the weekly PN volume and a younger age at the start of treatment (p = 0.028).   Conclusions: Teduglutide seems to be an effective and safe treatment for paediatric patients with IF. Some patients require a prolonged duration of treatment to achieve enteral autonomy. Starting treatment with teduglutide at a young age is associated with a higher response rate. What is Known: •  Glucagon-like peptide-2 (GLP-2) plays a crucial role in the regulation of intestinal adaptation in short bowel syndrome (SBS). Teduglutide is a GLP-2 analog that reduces the need for parenteral support in patients with SBS. • Data about long-term therapy with teduglutide in children in real life are still scarce. What is New: • Most pediatric patients with SBS respond in a satisfactory manner to teduglutide treatment. The occurrence of long-term adverse effects is exceptional. • Starting treatment with the drug at a young age is associated with a greater response rate.

Management of Short Bowel Syndrome (SBS) and Intestinal Failure.

Short bowel syndrome (SBS) is a chronic disease whose natural history requires a changing array of management strategies over time. Chief amongst these is the chronic use of parenteral nutrition (PN) to ensure adequate nutritional intake. With time and appropriate management, approximately half of all SBS patients will successfully regain a functional, baseline level of intrinsic bowel function that will allow for them to achieve PN independence. However, the other half of SBS patients will progress into chronic intestinal failure which warrants a change in therapy to include more aggressive medical and potentially surgical measures. This review examines the evolving treatment strategies involved in the management of SBS as well as intestinal failure.

Efficacy, safety, and pharmacokinetics of teduglutide in adult Japanese patients with short bowel syndrome and intestinal failure: two phase III studies with an extension.

PURPOSE: The short- and long-term efficacy, safety, and pharmacokinetics of teduglutide were analyzed in adult Japanese patients with short bowel syndrome and intestinal failure (SBS-IF). METHODS: Patients received teduglutide 0.05 mg/kg/day in clinical trials (TED-C14-004, SHP633-306, and extension SHP633-307). Data were analyzed at 24 weeks and an interim data cut-off of 4.5 years. RESULTS: The parenteral support (PS) volume decreased by ≥ 20% for 9/18 patients at 24 weeks and in all 11 patients by data cut-off in SHP633-307. The mean (standard deviation) PS volume decreased from baseline at 24 weeks in TED-C14-004 (-30.1 ± 25.9%) and SHP633-306 (-25.6 ± 25.5%), and at data cut-off in SHP633-307 (-57.08 ± 28.49%). Teduglutide was absorbed quickly. The adverse events were consistent with the underlying disease and known adverse drug reactions. Anti-teduglutide antibody titers declined with long-term treatment. CONCLUSIONS: In Japanese adults with SBS-IF, teduglutide treatment was associated with clinically meaningful reductions in PS requirements, similar to findings in prior international studies. No new safety concerns specific to the Japanese SBS-IF patient population were identified with short- or long-term teduglutide treatment. Anti-teduglutide antibody titers disappeared in most Japanese adults with long-term treatment. These results constitute the longest evaluation of teduglutide treatment within clinical trials reported to date.

Current management of bowel failure due to Crohn's disease in Spain: Results of a GETECCU survey. / Manejo actual del fracaso intestinal por enfermedad de Crohn en nuestro medio: resultados de una encuesta GETECCU.

INTRODUCTION: Intestinal failure is a rare pathology which requires knowledge and highly specialized multidisciplinary management. Crohn's disease (CD) being one of the most frequent causes in adults. MATERIAL AND METHODS: Survey format study carried out within the GETECCU group, included closed format questions about the diagnosis, management and current knowledge of intestinal failure in CD. RESULTS: Forty-nine doctors participated, belonging to different Spanish centers (19 cities). It was considered that a patient suffered from intestinal failure, in 67.3% (33/49 surveyed) when there was a disorder malabsorptive associated regardless of the intestinal length resected, with surgeries resective ileal repeated (40.8%, 20/49), the most frequent cause. It highlights frequent ignorance about the pathology (24.5%) did not know if there were patients in their center and also 40% did not know the pharmacological treatment. A total of 228 patients were registered for follow-up due to intestinal failure of any aetiology, 89 patients (39.5%) were identified with CD. Regarding the therapeutic management of patients with CD and intestinal failure (72.5%) were receiving total parenteral nutrition (NTP) and 24 patients (27%) with teduglutide. Regarding the response to the drug: 37.5% had no response to teduglutide, 37.5% partial response (reduce NTP) and 25% good response (withdrawal of home NTP). In questions related to knowledge about intestinal failure, it was considered limited (53.1%) or very limited (12.2%) by the surveyed. CONCLUSION: It is necessary to carry out a combined management of intestinal failure and CD in the context of a multidisciplinary approach.

Approach to Intestinal Failure in Children.

PURPOSE OF REVIEW: Pediatric intestinal failure is a complex condition requiring specialized care to prevent potential complications. In this article, we review the available evidence supporting recent advances in care for children with intestinal failure. RECENT FINDINGS: Multidisciplinary intestinal rehabilitation teams utilize medical and surgical management techniques to help patients achieve enteral autonomy (EA) while preventing and treating the complications associated with intestinal failure. Recent advances in lipid management strategies, minimization of intestinal failure associated liver disease, prevention of central line-associated blood stream infections, and loss of access, as well as development of promising new hormone analogue therapy have allowed promotion of intestinal adaptation. These advances have decreased the need for intestinal transplant. There have been recent advances in the care of children with intestinal failure decreasing morbidity, mortality, and need for intestinal transplantation. The most promising new therapies involve replacement of enteroendocrine hormones.

GLP-2 Acutely Prevents Endotoxin-Related Increased Intestinal Paracellular Permeability in Rats.

BACKGROUND: Circulating endotoxin (lipopolysaccharide, LPS) increases the gut paracellular permeability. We hypothesized that glucagon-like peptide-2 (GLP-2) acutely reduces LPS-related increased intestinal paracellular permeability by a mechanism unrelated to its intestinotrophic effect. METHODS: We assessed small intestinal paracellular permeability in vivo by measuring the appearance of intraduodenally perfused FITC-dextran 4000 (FD4) into the portal vein (PV) in rats 1-24 h after LPS treatment (5 mg/kg, ip). We also examined the effect of a stable GLP-2 analog teduglutide (TDG) on FD4 permeability. RESULTS: FD4 movement into the PV was increased 6 h, but not 1 or 3 h after LPS treatment, with increased PV GLP-2 levels and increased mRNA expressions of proinflammatory cytokines and proglucagon in the ileal mucosa. Co-treatment with a GLP-2 receptor antagonist enhanced PV FD4 concentrations. PV FD4 concentrations 24 h after LPS were higher than FD4 concentrations 6 h after LPS, reduced by exogenous GLP-2 treatment given 6 or 12 h after LPS treatment. FD4 uptake measured 6 h after LPS was reduced by TDG 3 or 6 h after LPS treatment. TDG-associated reduced FD4 uptake was reversed by the VPAC1 antagonist PG97-269 or L-NAME, not by EGF or IGF1 receptor inhibitors. CONCLUSIONS: Systemic LPS releases endogenous GLP-2, reducing LPS-related increased permeability. The therapeutic window of exogenous GLP-2 administration is at minimum within 6-12 h after LPS treatment. Exogenous GLP-2 treatment is of value in the prevention of increased paracellular permeability associated with endotoxemia.

Teduglutide Promotes Epithelial Tight Junction Pore Function in Murine Short Bowel Syndrome to Alleviate Intestinal Insufficiency.

BACKGROUND: In short bowel syndrome, epithelial surface loss results in impaired nutrient absorption and may lead to intestinal insufficiency or intestinal failure. Nucleotide oligomerization domain 2 (Nod2) dysfunction predisposes to the development of intestinal failure after intestinal resection and is associated with intestinal barrier defects. Epithelial barrier function is crucial for intestinal absorption and for intestinal adaptation in the short bowel situation. AIMS: The aim of the study was to characterize the effects of the GLP-2 analogue Teduglutide in the small intestine in the presence and absence of Nod2 in a mouse model of short bowel syndrome. METHODS: Mice underwent 40% ICR and were thereafter treated with Teduglutide versus vehicle injections. Survival, body weight, stool water, and sodium content and plasma aldosterone concentrations were determined. Intestinal and kidney tissue was examined with light and fluorescence microscopy, Ussing chamber studies and quantitative PCR in wild type and transgenic mice. RESULTS: Teduglutide reduced intestinal failure incidence in Nod2 k.o. mice. In wt mice, Teduglutide attenuated intestinal insufficiency as indicated by reduced body weight loss and lower plasma aldosterone concentrations, lower stool water content, and lower stool sodium losses. Teduglutide treatment was associated with enhanced epithelial paracellular pore function and enhanced claudin-10 expression in tight junctions in the villus tips, where it colocalized with sodium-glucose cotransporter 1 (SGLT-1), which mediates Na-coupled glucose transport. CONCLUSIONS: In the SBS situation, Teduglutide not only maximizes small intestinal mucosal hypertrophy but also partially restores small intestinal epithelial function through an altered distribution of claudin-10, facilitating sodium recirculation for Na-coupled glucose transport and water absorption.

Off-Label Teduglutide Therapy in Non-intestinal Failure Patients with Chronic Malabsorption.

BACKGROUND: Teduglutide, a glucagon-like peptide 2 analog, has demonstrated efficacy in treating adult patients with short bowel syndrome (SBS) and dependence on parenteral nutrition (PN), but its role in chronic malabsorptive states that do not necessitate PN remains uncertain. AIMS: To evaluate teduglutide use beyond its approved indications and to discuss the results of this adjunctive treatment in patients resistant to established therapy. RESULTS: This series reports four patients treated with teduglutide off-label. The first case had Crohn's disease (CD) with persistent colocutaneous fistulae that demonstrated complete closure after 8 months of teduglutide therapy. The second case involved a PN-dependent CD patient with persistent fistulae and intra-abdominal abscesses who weaned off PN and had a significant improvement in her nutritional status after 3 months of teduglutide therapy. The third case had CD complicated by severe malnutrition and previous PN-associated line infections, but by 9 months of teduglutide therapy, she gained 5 kg and no longer required re-initiation of PN. The fourth case had a high-output diverting ileostomy with resultant impaired healing of a stage IV decubitus ulcer, and after 2 months of therapy, the patient's pre-albumin increased by 250% and the ulcer had decreased by 40% in size. CONCLUSION: The use of teduglutide might be broadened to include patients with functional SBS not meeting strict criteria for intestinal failure. Further studies should evaluate the efficacy of teduglutide in patients who may require short-term small intestine rehabilitation or who have chronically impaired absorptive capacity not yet requiring PN.

Teduglutide effects on gene regulation of fibrogenesis on an animal model of intestinal anastomosis.

BACKGROUND: Teduglutide is an enterotrophic analog of glucagon-like peptide 2 approved for the rehabilitation of short-bowel syndrome. This study aims to analyze the effects of teduglutide administration on the gene regulation of fibrogenesis during the intestinal anastomotic healing on an animal model. METHODS: Wistar rats (n = 62) were assigned into four groups: "Ileal Resection and Anastomosis" or "Laparotomy," each one subdivided into "Postoperative Teduglutide Administration" or "No Treatment," and sacrificed at the third or at the seventh days, with ileal sample harvesting. Gene expression of matrix components and remodeling factors (matrix metalloproteinases [Mmp] and tissue inhibitors of metalloproteinases [Timp]) and growth factors was studied by real-time polymerase chain reaction. Net collagen deposition was assessed through the Collagen-to-Mmp-to-Timp ratio of fold change of relative gene expression. RESULTS: Gene expression profiles revealed a balance toward net degradation of collagen at the third day of the intestinal anastomotic healing. Teduglutide appeared to be associated with an overall accumulation of collagen at the third day of the anastomotic repair, attributable to the upregulation of Collagen type 1 alpha 1, Collagen type 3 alpha 1, and Collagen type 4 alpha 1, Timp1, and Timp2 and downregulation of Mmp13 and to a net degradation of collagen at the seventh day, derived from repression of Collagen type 3 alpha 1, Collagen type 5 alpha 1 and Timp1 expression. CONCLUSIONS: Teduglutide appeared to be associated with a favorable influence on fibrogenesis at the third day of the intestinal anastomotic repair and to a trend to fibrolysis at the seventh day.

Optimizing peripubertal growth in a child with short bowel syndrome on full oral feeding with glucagon-like peptide 2 analog.

Teduglutide is a glucagon-like peptide 2 (GLP-2) analog which acts by increasing intestinal absorption of the remnant bowel for children with short bowel syndrome (SBS) dependent on parenteral nutrition. We present a 13-year-old male patient with type 2 SBS (55 cm of jejunum) from necrotizing enterocolitis on full oral feeding from the age of 12 months. Because of faltering growth from the age of 11 despite oral hyperphagia, he started Teduglutide at the standard dose. Eighteen months after Teduglutide start the young boy gained 10 kg in weight and 13 cm in height with a significant reduction in bowel distension. No adverse events were reported during the treatment. Pubertal spurt might be impaired in children with SBS on full oral feeding if the caloric need is not met by the residual intestinal absorption rate. GLP-2 analog might represent an option to sustain pubertal spurt in SBS children on full oral feeding with hyperphagia.

Long-term outcomes and adverse effects of teduglutide in patients with short bowel syndrome: Highlighting hyperamylasemia and hyperlipasemia.

PURPOSE: Short bowel syndrome is a malabsorptive condition that occurs due to surgical removal or a congenital absence of a significant portion of the small intestine. Patients with short bowel syndrome often rely on parenteral support for extended periods or even their entire lives. Teduglutide, a glucagon-like peptide-2 analog, has shown promising results in reducing dependency on parenteral support in these patients by promoting intestinal adaptation and enhancing nutrient absorption. However, the long-term safety of teduglutide remains a concern, particularly with respect to its potential for the development of hyperamylasemia and hyperlipasemia. METHODS: This study involved patients who received teduglutide from December 2012 to December 2022 at Boston Medical Center. We evaluated outcomes and adverse events, focusing on hyperamylasemia and hyperlipasemia, through chart review. RESULTS: Thirteen eligible patients were identified who had used teduglutide. Of these, the majority (84.6%) experienced a reduction in parenteral support. A high incidence (72.7%) of nonpathological pancreatic enzyme elevation was observed in patients treated with teduglutide. These elevations were often dose dependent and were not associated with any clinical signs of acute pancreatitis or abnormal imaging findings. CONCLUSION: This study highlights the need for further investigations into the long-term safety of teduglutide and the importance of closely monitoring amylase and lipase levels in patients undergoing treatment with teduglutide.

Cost-effectiveness of teduglutide in adult patients with short bowel syndrome - a European socioeconomic perspective.

BACKGROUND: Short bowel syndrome with intestinal failure (SBS-IF) is a rare but devastating medical condition. An absolute loss of bowel length forces the patients into parenteral support dependency and a variety of medical sequelae, resulting in increased morbidity and mortality. Interdisciplinary treatment may include therapy with the effective but expensive intestinotrophic peptide teduglutide. OBJECTIVES: A time-discrete Markov model was developed to simulate the treatment effect [lifetime costs, quality-adjusted life years (QALYs), and life years (LYs)] of teduglutide plus best supportive care compared with best supportive care alone in patients with SBS-IF. METHODS: The health status of the model was structured around the number of days on PS. Clinical data from 3 data sets were used: 1) an Austrian observational study (base case), 2) pooled observational cohort studies, and 3) a prospective study of teduglutide effectiveness in parenteral nutrition-dependent short bowel syndrome subjects. Direct and indirect costs were derived from published sources. QALYs, LYs, and costs were discounted (3% per annum). RESULTS: Under the base case assumption, teduglutide is associated with costs of 2,296,311 € per patient and 10.78 QALYs (13.74 LYs) over a lifetime horizon. No teduglutide is associated with 1,236,816 € and 2.24 QALYs (8.57 LYs). The incremental cost-utility ratio (ICUR) amounts to 123,945 €. In case of the pooled clinical data set, the ICUR increases to 184,961 €. If clinical data based on the study of teduglutide effectiveness in parenteral nutrition-dependent short bowel syndrome subjects were used, the ICUR increased to 235,612 €. CONCLUSIONS: Teduglutide in treating patients with SBS-IF meets the traditional cost-effectiveness criteria from a European societal perspective. Nevertheless, the varying concentrations of teduglutide efficacy leave a degree of uncertainty in the calculations.

Retrospective review of growth in pediatric intestinal failure after weaning from parenteral nutrition.

BACKGROUND: Growth outcomes in children with intestinal failure (IF) after weaning from parenteral nutrition (PN) may be modified by primary diagnosis and interventions aimed at achieving enteral tolerance. We evaluated growth after weaning by diagnosis and intestinal transplant status and during treatment with the glucagon-like peptide-2 analog teduglutide. METHODS: A two-center retrospective review was conducted on children diagnosed with IF at age <12 months. The z scores for weight and length/height were examined up to 5 years after PN weaning and in children who received teduglutide for >6 months. Data were reported as median and interquartile range (IQR). RESULTS: A total of 362 children (58% male and 72% White) were reviewed; 41% (n = 150) weaned from PN at age 1.5 years (IQR = 0.96-3). Weight and length/height data were available for 144 children; 46 received an intestinal transplant. Median weight and length/height z scores at weaning were -1.15 (IQR = -2.09 to -0.39) and -1.89 (IQR = -2.9 to -1.02), respectively. In those not transplanted, z scores remained stable (± 0.5 change). Children with small bowel atresia experienced accelerated linear growth (> +0.5 change) beginning in year 3. Most children transplanted experienced growth acceleration beginning in year 2. Fourteen children received teduglutide (median = 840 [IQR = 425-1530] days), and growth remained stable throughout treatment. Five were weaned from PN within 1 year. CONCLUSION: We observed stable growth with limited catch-up after PN weaning, with minimal variation by diagnosis, and during teduglutide therapy. Children who received an intestinal transplant experienced acceleration in weight and linear growth after weaning.

Use of Teduglutide in the Management of Gastrointestinal Graft-versus-Host Disease in Children and Young Adults.

Loss of intestinal L cells and reduced levels of glucagon-like peptide-2 (GLP-2) have been implicated in acute graft-versus-host disease (GVHD) in murine models. Teduglutide, a human recombinant GLP-2 analog, may be beneficial in acute gastrointestinal (GI) GVHD owing to its known tissue protective and regenerative functions. We retrospectively reviewed patients who received teduglutide for treatment of GI GVHD. Endoscopy was performed at diagnosis and at completion of the teduglutide course. GLP-1 immunohistochemistry (IHC) was performed at diagnosis and the end of teduglutide therapy in 2 patients to evaluate L cells. We initiated daily teduglutide 0.05 mg/kg subcutaneously as adjunctive therapy in 3 pediatric patients with refractory GI GVHD. All 3 patients had resolution of GI GVHD following completion of the teduglutide course, as evidenced by reduced apoptosis and regenerative changes on post-treatment endoscopy. Reportable GLP-1 IHC in 2 patients demonstrated increased L cells at the end of teduglutide treatment compared to at diagnosis. No adverse effects to teduglutide were observed. Teduglutide is a promising adjunctive and non-immune suppressive agent for managing acute GI GVHD.

Evaluation of the Effectiveness of Teduglutide Treatment in Patients with Short Bowel Syndrome in Slovakia-Multicenter Real-World Study.

(1) Background: We present the first real-world-data study on teduglutide-treated SBS patients in the Slovak Republic and the first study to enable the comparison of the effects of teduglutide treatment between the adult and pediatric populations. (2) Methods: This was a non-interventional retrospective cohort study of adult and pediatric SBS patients treated with teduglutide. Primary and secondary endpoints were the results of teduglutide use at 12 weeks and 6 months after the initiation of treatment, compared to baseline. (3) Results: Teduglutide treatment led to a statistically significant reduction in the volume of intravenous hydration, HPN caloric intake, HPN and intravenous hydration applications per week and to increased urine output in adult patients. The results in the pediatric population were similar, but not statistically significant. A complete weaning off HPN was achieved in 57.14% of all patients (50.00% of children; 62.50% of adults) after a median of 0.99 years of teduglutide treatment (1.07 and 0.98 years for children and adults, respectively). (4) Conclusions: Teduglutide treatment in SBS patients leads to considerable reduction in or even weaning off PN in both pediatric and adult patients.

The real-world analysis of adverse events with teduglutide: a pharmacovigilance study based on the FAERS database.

Background: Teduglutide, the first glucagon-like peptide 2 analogue, has been demonstrated to facilitate the absorption of gut nutrient and lessen the need for parenteral assistance in patients with Short Bowel Syndrome (SBS). However, its adverse drug events (AEs) are primarily documented in clinical trials, with a deficit in real-world data. This study evaluates the AEs profile of teduglutide based on Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) data. Method: A disproportionality analysis of FAERS data from Quarter 1 (Q1) 2013 to Quarter 3 (Q3) 2023 was conducted to examine the association between teduglutide and adverse events, employing Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and Empirical Bayesian Geometric Mean (EBGM) methods. Results: Out of 13,809,302 reports in the FAERS database, 10,114 reports identified teduglutide as the "primary suspect" in AEs identification. During the dosing observation period, the median occurrence of adverse events was 393 days (interquartile range [IQR] 97-996 days). Teduglutide-associated AEs occurred in 27 System Organ Classes (SOC), of which renal and urinary disorders is not mentioned in the specification. Based on the four algorithms, a total of 260 major disproportionality preferred terms (PTs) were filtered out, including previously unreported AEs including weight decreased (n = 805), vascular device infection (n = 683), dehydration (n = 596) and nephrolithiasis (n = 146). Conclusion: Our findings corroborate the AEs listed in the teduglutide prescribing information and additionally unveil new adverse reaction signals such as nephrolithiasis. These discoveries could aid in clinical monitoring and risk identification for teduglutide.

Teduglutide-induced acute gastric mucosal necrosis in short bowel syndrome with hepatorenal failure: Case report.

INTRODUCTION: Short bowel syndrome (SBS) resulting from acute aortic dissection (AAD)-induced visceral malperfusions leads to chronic intestinal failure (CIF), necessitating patients to adopt home parenteral nutrition to prevent malabsorption. Teduglutide (TED), a glucagon-like peptide-2 analog, is a promising pharmacotherapy for intestinal rehabilitation that reduces parenteral support and improves the quality of life. Gastric mucosal necrosis, a rare gastrointestinal disorder, had never been observed as an adverse event relevant to this drug. We report a case of mucosal necrosis in the stomach after TED treatment for SBS-CIF with hepatorenal failure. PRESENTATION OF CASE: A 68-year-old Japanese man who underwent massive intestinal resection for AAD experienced malnutrition and diarrhea caused by SBS-CIF. The patient received TED to improve intestinal absorption and entero-hepatic circulation besides controlling infectious diseases. Endoscopy showed mucosal hyperplasia in the stomach and duodenum 1.5 months after TED administration. The patient consented to enteral nutrition via a nasogastric tube because of anorexia. The nutritional status gradually improved after initiating enteral feeding. However, the patient experienced hematemesis 13 days after enteral feeding, and endoscopy revealed acute gastric mucosal necrosis, followed by fatal septic shock. DISCUSSION: For patients with SBS, TED is expected to increase intestinal absorption through epithelial proliferation. When SBS is accompanied by multiple ischemic organ failure, TED therapeutic effects remain unclear as malnutrition-associated infectious diseases are refractory, and many underlying mechanisms can be involved. CONCLUSION: TED administration should be deliberately considered for patients with SBS-CIF and multiple organ failure experiencing uncontrolled systemic infection.
