Teduglutide is a GLP-2 analog currently evaluated for the treatment of short bowel syndrome, Crohn's disease, and other gastrointestinal disorders. The population pharmacokinetics (PK) of teduglutide were assessed following daily subcutaneous (SC) administrations of 2.5 to 80 mg doses in a total of 256 patients. A 1-compartment model with a site-specific rate constant of absorption in the abdomen, arm, and thigh was used to assess the PK of teduglutide. Apparent clearance (CL/F) of teduglutide in male participants was approximately 18% higher than that observed in female participants (12.4 vs 10.5 L/h, respectively). Body weight was detected as a significant covariate explaining the volume of distribution of teduglutide. The elimination half-life (t((1/2))) of teduglutide was also influenced by the body weight of participants. For a male patient weighing 50 and 90 kg, t((1/2)) of teduglutide was 0.897 and 2.99 hours, respectively. Renal and hepatic function of patients did not affect the PK of teduglutide. As a result, no dose adjustment was deemed necessary in patients with altered renal or liver function. The population PK model will help to support adequate drug labeling following SC administrations in patients and determine whether an individualized dosage is required.

Malabsorption of nutrients, fluids and electrolytes is a key finding in patients with short bowel syndrome. If not compensated for by increased intake, it leads to diminished body stores and subclinical, and eventually clinical, deficiencies. Until recently, management options were limited to interventions aimed at provision of adequate macro- and micronutrients and fluids to prevent malnutrition, nutrient deficiencies and dehydration, treatment of associated infections and correction and prevention of acid-base disturbances. Identification of novel gut hormones, combined with the growing understanding of their pivotal role in intestinal adaptation, has provoked interest in developing more specific therapies.. To provide an update on the recent advances on the use of teduglutide in patients with short bowel syndrome.. A comprehensive Medline search using the terms teduglutide, ALX-0600, dipeptidyl peptidase IV (DPP-IV) and glucagon like peptide-2 (GLP-2).. Teduglutide (GATTEX, ALX-0600; NPS Allelix Corp) is a synthetic DPP-IV-resistant recombinant human GLP-2 analog that differs from GLP-2 only by an N-terminus substitution of glycine for alanine in position 2 of the peptide that renders the component resistant to enzymatic degradation. Based on the results of the few Phase II studies and the preliminary results of a Phase III trial, teduglutide at doses of 0.05 or 0.10 mg/kg/day may improve many clinical, laboratory and histologic abnormalities in short bowel syndrome patients. It appears to be safe and well tolerated.. Teduglutide is a first-in-class therapy with the potential to create a new standard of care for patients suffering from short bowel syndrome. Future studies to address the appropriate initial and maintenance dosage and optimal duration of treatment are needed.

Teduglutide, an analog of glucagon-like peptide-2 (GLP-2), is associated with trophic effects on gut mucosa. Its role in the treatment of active Crohn's disease (CD) was assessed in a pilot, randomized, placebo-controlled, double-blinded, dose-ranging study.. Subjects with moderate-to-severe CD were randomized 1:1:1:1 to placebo or 1 of 3 doses of teduglutide (0.05, 0.10, or 0.20 mg/kg daily) delivered as a daily subcutaneous injection for 8 weeks. The primary outcome measure was the percentage of subjects in each group that responded to treatment, defined as a decrease in Crohn's Disease Activity Index (CDAI) score to <150 or a decrease of > 100 points. At week 8 there was an optional 12-week open-label period of treatment with teduglutide 0.10 mg/kg/d.. One hundred subjects were enrolled and 71 completed the study. The mean baseline CDAI score was 290.8 +/- 57.6 and was similar across groups. There were numerically higher response and remission rates in all teduglutide-treated groups as compared with placebo, although the percentage of subjects who achieved a clinical response or remission was more substantial, and seen as early as week 2 of treatment in the highest dose (0.2 mg/kg/d) group (44% response and 32% remission versus 32% response and 20% remission in the placebo group). Of subjects who had not achieved remission during the 8-week placebo-controlled phase in the higher-dose group, 50% achieved remission during the more prolonged, open-label treatment phase. Plasma citrulline was similar across groups at baseline, but increased substantially over time in all teduglutide groups when compared with placebo at week 8. Adverse events were not different between placebo and active treatment groups.. Teduglutide is a novel and potentially effective therapy for inducing remission and mucosal healing in patients with active moderate-to-severe CD. Further clinical investigation of this growth factor is warranted.

Surgery in Crohn's disease may be the cause of short bowel syndrome that may lead to kidney dysfunction. Dual biologic therapy is rarely needed to control activity. We present a case of a 61-year-old steroid dependent (A2L1B3p) female who had undergone surgery on three occasions: ileocecal resection (resection of 15 cm of terminal ileum); resection of right and left colon up to sigmoid; proctectomy with intersphincteric resection along with ileostomy due to a rectovaginal fistula. She had been previously treated with prednisone, azathioprine, methotrexate, infliximab and adalimumab but the treatment was discontinued owing to adverse effects. Vedolizumab was started, showing good control of the luminal activity but the rectovaginal fistula recurred. Treatment changed to ustekinumab, the fistula activity was controlled but the mucosa activity recurred. 11 months after commencing with ustekinumab, vedolizumab was added to the treatment and complete remission was achieved for three years. Simultaneously, the patient developed renal dysfunction derived from the short bowel syndrome that led to chronic kidney failure. In the face of potential renal replacement therapy, a new therapy with 2.5 mg/sc/d teduglutide was started achieving stable figures of creatinine and normalization of the glomerular filtration rate.

The short-term effects of teduglutide (TED) for short bowel syndrome with chronic intestinal failure (SBS-IF) in patients with Crohn's disease (CD) remain unknown. The aim of this study was to investigate the effects of TED in patients with CD on home parenteral support (PS) for SBS-IF.. We retrospectively investigated the medical records of patients with CD associated with SBS-IF who initiated TED between 2020 and 2021. The primary outcomes were the change in PS volume and proportion of patients with a reduction of PS volume by ≥ 20% at week 8. Secondary outcomes were the change in PS volume in patients with CD without/with colon in continuity and adverse events during the observation period.. Eighteen patients with CD who underwent home PS for SBS-IF were included in this study. Two patients were excluded owing to intolerable abdominal pain or vomiting within 8 weeks (11%). Sixteen patients continued TED throughout the observation period. The median PS duration was 10.5 years. The median observation period was 22 weeks after starting TED. TED significantly reduced the PS volume from 15,825.0 mL/week to 10,700.0 mL/week (p = 0.0038), and the PS volume decreased by ≥ 20% in 7 patients (43.8%) at week 8. The PS volume was significantly reduced at week 4 (p = 0.0078) in 11 patients without colon in continuity but not in 5 patients with colon in continuity. Two patients successfully stopped home PS. No serious adverse events occurred.. TED administration significantly reduced PS volume at week 8 in patients with CD associated with SBS-IF, and at week 4 in patients without colon in continuity.

Intestinal failure (IF) is defined as a reduction in intestinal function below the minimum necessary for the absorption of nutrients, requiring intravenous supplementation to maintain health and/or growth. The most common cause is short bowel syndrome (SBS). Approximately 50% of patients with SBS have IF and require parenteral support. Teduglutide is a human glucagon-like peptide-2 analogue (GLP-2) approved for the treatment of patients with SBS. Clinical trial results have proven its efficacy by reducing volume and days of administration of parenteral nutrition and fluid therapy. Few publications evaluate the effects on long-term bowel function in respondent patients after teduglutide suspension. A patient with type I SBS (terminal jejunostomy) due to multiple surgeries for Crohn's disease, who was treated with liraglutide for one year and sequential teduglutide for 21 months, is described. With the former, a reduction in the need for contribution and debit by jejunostomy was observed. The GLP-2 analogue achieved a greater reduction in the hydric disbalance that allowed the suspension of the nocturnal suerotherapy, with weight gain and maintenance of nutritional parameters; situation maintained two years after its suspension.. El fallo intestinal se define como una reducción de la función intestinal por debajo del mínimo necesario para la absorción de nutrientes y que precisa suplementación intravenosa para mantener la salud y/o el crecimiento. La causa más frecuente es el síndrome de intestino corto. Aproximadamente el 50% de pacientes con SIC presenta FI y requiere soporte parenteral. Teduglutida es un análogo del péptido-2 similar al glucagón (GLP-2) humano aprobado para el tratamiento de pacientes con SIC. Los resultados de ensayos clínicos han probado su eficacia: se reducen el volumen y los días de administración de nutrición parenteral y fluidoterapia. Pocas publicaciones evalúan los efectos sobre la función intestinal a largo plazo en pacientes respondedores tras la suspensión de teduglutida. Se describe un paciente con SIC tipo I (yeyunostomía terminal) debido a múltiples intervenciones quirúrgicas por enfermedad de Crohn, que recibió tratamiento con liraglutida un año y teduglutida secuencial durante 21 meses. Con el primero, se objetivó una reducción en la necesidad de aporte y débito por yeyunostomía. El análogo del GLP-2 consiguió una mayor reducción del desequilibrio hídrico que permitió suspender sueroterapia nocturna, con ganancia ponderal y mantenimiento de parámetros nutricionales, situación mantenida dos años después de su suspensión.

Teduglutide is a GLP-2 analogue indicated for treatment of adults with short bowel syndrome (SBS). Because of the rarity of SBS, real-world safety or efficacy data are not available in patients with Crohn's disease (CD) and SBS treated with teduglutide.. To evaluate teduglutide's safety and efficacy in CD patients with SBS.. We conducted a retrospective cohort study at 3 tertiary centers in the United States between 2012 and 2014. Demographic, clinical, and therapeutic data were retrieved from medical record systems.. Thirteen CD patients were included, 8 (62%) of whom were on concomitant immunosuppression. Median duration of teduglutide therapy was 365 days [interquartile range (IQR), 122 to 482 d] and 9/13 patients (69%) remain on therapy. At teduglutide initiation, 69% were on parenteral nutrition. At conclusion of follow-up, 1 patient was on parenteral nutrition. All patients were on intravenous fluids (IVF) before teduglutide; median IVF were 9000 mL/wk (IQR, 7000 to 14,000 mL/wk). IVF requirements decreased by a median of 3100 mL/wk (IQR, 2400 to 8400 mL/wk). Six patients (46%) ceased IVF. Adverse events attributed to teduglutide were obstructive symptoms (n=1), pancreatitis (n=1), asymptomatic lipase and amylase elevation (n=1), nausea (n=1), and abdominal pain (n=1). Catheter-related sepsis occurred in 4 patients.. This is the first report evaluating the safety and efficacy of teduglutide in a cohort of CD patients with SBS requiring parenteral support. More of half the cohort was on concomitant immunosuppression. Teduglutide seemed to be safe and the majority of patients were weaned off parenteral support.

Glucagon-like peptide-2 (GLP-2) is a potent intestinotrophic growth factor with therapeutic potential for the prevention or treatment of an expanding number of gastrointestinal diseases, including short bowel syndrome (SBS). Teduglutide, being developed by NPS Allelix and licensee Nycomed, is a protease-resistant analog of GLP-2 for the potential treatment of gastrointestinal disease. Teduglutide has prolonged biological activity compared with native GLP-2, and preclinical studies demonstrated significant intestinotrophic activity in models of SBS, experimental colitis and chemotherapy-induced intestinal mucositis. Patients with SBS rely on parenteral nutrition (PN) following bowel resection, and in a phase III clinical trial with teduglutide, > 20% reduction in PN was observed in patients with SBS receiving teduglutide. A phase II clinical trial for teduglutide in Crohn's disease observed remission rates of 55.6% in patients. At the time of publication, phase III clinical trials for SBS were ongoing, as were preclinical studies for chemotherapy-induced mucositis and pediatric indications. Teduglutide represents a novel, efficacious drug capable of increasing intestinal growth and improving intestinal function, and may change clinical management of intestinal disease and damage.
