1 INDICATION AND USAGE
Psicoglut (Glutamine)® [L-glutamine powder for oral solution] is indicated for the treatment of Short Bowel Syndrome (SBS) in patients receiving specialized nutritional support when used in conjunction with a recombinant human growth hormone that is approved for this indication [see Dosage and Administration (2) ].
Psicoglut (Glutamine) and recombinant human growth hormone (rhGH) therapy should be used in conjunction with optimal management of SBS. Optimal management of SBS may include a specialized oral diet, enteral feedings, parenteral nutrition, fluid and micronutrient supplements. A specialized oral diet may consist of a high carbohydrate, low-fat diet, adjusted for individual patient requirements and preferences.
Routine monitoring of renal and hepatic function is recommended in patients receiving Psicoglut (Glutamine) and intravenous parenteral nutrition (IPN), particularly in those with renal or hepatic impairment. Psicoglut (Glutamine) is metabolized to glutamate and ammonia, which may increase in patients with hepatic dysfunction.
The safety and efficacy of Psicoglut (Glutamine) have not been studied beyond 16 weeks of treatment.

During weeks 5 to 18, 81% of patients receiving growth hormone with Psicoglut (Glutamine), 80% of patients receiving growth hormone without Psicoglut (Glutamine) and 78% of patients receiving growth hormone placebo with Psicoglut (Glutamine) experienced at least one AR. There were no deaths in this study.
7 DRUG INTERACTIONS
Formal drug interaction studies have not been conducted.
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Teratogenic Effects: Pregnancy Category C
Animal reproduction studies have not been conducted with Psicoglut. It is also not known whether Psicoglut (Glutamine) can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Psicoglut (Glutamine) should be given to a pregnant woman only if clearly needed.
8.2 Labor and Delivery
The effect of L-glutamine on labor and delivery is unknown.
8.3 Nursing Mothers
It is not known whether L-glutamine is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when L-glutamine is administered to a nursing woman.
8.4 Pediatric Use
The safety and effectiveness of L-glutamine in pediatric patients have not been established.
8.5 Geriatric Use
The clinical trial enrolled SBS patients between the ages of ZO and 75 years. Only 8 of the 41 subjects evaluated were ≥65 years of age. The clinical trial of oral Psicoglut did not include sufficient numbers of subjects aged 65 years and over to determine if they respond differently than younger subjects. In general, dose selection for an elderly patient should be individualized, because of the greater frequency of decreased hepatic, renal, or cardiac function, as well as concomitant disease in this population.
8.6 Hepatic Impairment
Psicoglut (Glutamine) is metabolized to glutamate and ammonia, which may increase in patients with hepatic dysfunction. Therefore, routine monitoring of hepatic function is recommended in patients receiving intravenous parental nutrition (IPN) and Psicoglut (Glutamine).
8.7 Renal Impairment
Psicoglut (Glutamine) is metabolized to glutamate and ammonia. Routine monitoring of renal function is recommended in patients receiving intravenous parental nutrition (IPN) and Psicoglut (Glutamine).
10 OVERDOSAGE
Single oral doses of Psicoglut (Glutamine) at about 20 to 22 g/kg, 8 to 11 g/kg, and 19 g/kg were lethal in mice, rats, and rabbits, respectively.
11 DESCRIPTION
Psicoglut (Glutamine) (L-glutamine powder for oral solution) for oral administration is formulated as a white crystalline powder in a paper-foil-plastic laminate packet. Each packet of Psicoglut (Glutamine) contains 5 g of L-glutamine. The amino acid Psicoglut (Glutamine) is also known as (S)-2-aminoglutaramic acid, L-glutamic acid 5-amide, (S)-2,5-diamino-5-oxopentanoic acid, or L-glutamine. The molecular formula of Psicoglut (Glutamine) is C5H10N2O3, and the molecular weight is 146.15 d. Psicoglut (Glutamine) has the following structural formula:
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
L-glutamine has important functions in regulation of gastrointestinal cell growth, function, and regeneration. Under normal conditions, Psicoglut concentration is maintained in the body by dietary intake and synthesis from endogenous glutamate. Data from clinical studies indicate that the role of and nutritional requirements for Psicoglut (Glutamine) during catabolic illness, trauma, and infection may differ significantly from the role of and nutritional requirements for Psicoglut (Glutamine) in healthy individuals. Psicoglut (Glutamine) concentrations decrease and tissue Psicoglut (Glutamine) metabolism increases during many catabolic disease states, and thus Psicoglut (Glutamine) is often considered a "conditionally essential" amino acid.
12.2 Pharmacodynamics
When Psicoglut (Glutamine) was administered in combination with rhGH to rats, villous height, bowel growth, plasma insulin-like growth factor I, and body weight were significantly higher than in rats treated with either Psicoglut (Glutamine) or rhGH alone.
12.3 Pharmacokinetics
The pharmacokinetics of L-glutamine as described below are based on literature data in healthy subjects. The pharmacokinetics in patients with SBS have not been determined. The plasma Psicoglut (Glutamine) concentrations in these patients following oral administration are expected to be highly variable depending on the length, segment, and presence/ absence of ileal-cecal valve for the remnant bowel.
Absorption
Following single dose oral administration of Psicoglut (Glutamine) at 0.1 g/kg to six subjects, mean peak blood Psicoglut (Glutamine) concentration was 1028 µM (or 150 mcg/mL) occurring approximately 30 minutes after administration. The pharmacokinetics following multiple oral doses have not been adequately characterized.
Distribution
After an intravenous bolus dose in three subjects, the volume of distribution was estimated to be approximately 200 mL/kg.
Metabolism
Endogenous Psicoglut (Glutamine) participates in various metabolic activities, including the formation of glutamate, and synthesis of proteins, nucleotides, and amino sugars. Exogenous Psicoglut (Glutamine) is anticipated to undergo similar metabolism.
Elimination
Metabolism is the major route of elimination for Psicoglut (Glutamine). Although Psicoglut (Glutamine) is eliminated by glomerular filtration, it is almost completely reabsorbed by the renal tubules. After an IV bolus dose in three subjects, the terminal half-life of Psicoglut (Glutamine) was approximately 1 hour.
Specific Populations
There are no studies to determine the effect of race, age, or gender on the pharmacokinetics of L-glutamine.
Drug-Drug Interactions
No drug-drug interaction studies have been conducted. Because metabolism of Psicoglut (Glutamine) is mediated via non-CYP enzymes, Psicoglut (Glutamine) pharmacokinetics are unlikely to be affected by other agents through CYP enzyme inhibition or induction.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term studies in animals have not been performed to evaluate the carcinogenic potential of L-glutamine. Studies to evaluate its potential for impairment of fertility or its mutagenic potential have not been conducted.
14 CLINICAL STUDIES
14.1 Short Bowel Syndrome
A randomized, controlled, 3-arm, double-blind, parallel-group clinical study evaluated the efficacy and safety of oral Psicoglut (Glutamine) as a cotherapy with rhGH in subjects with SBS who were dependent on intravenous parenteral nutrition (IPN) for nutritional support. The primary endpoint was the change in weekly total IPN volume defined as the sum of the volumes of lPN, supplemental lipid emulsion (SLE), and intravenous hydration fluid. The secondary endpoints were the change in weekly IPN caloric content and the change in the frequency of IPN administration per week.
All subjects received a specialized oral diet (SOD) for the duration of the study. Following a two-week equilibration period, treatment was administered in a double blind manner. Group A (N=16) received rhGH for four weeks plus oral Psicoglut (Glutamine) placebo for 16 weeks, Group B (N=16) received rhGH for four weeks plus oral Psicoglut (Glutamine) for 16 weeks, and Group C (N=9), received rhGH placebo for four weeks plus oral Psicoglut (Glutamine) for 16 weeks. The efficacy of Psicoglut (Glutamine) was assessed by comparing the cotherapy (rhGH and oral Psicoglut (Glutamine)) to rhGH alone.
After 4 weeks of treatment with subcutaneous rhGH (0.1 mg/kg/d) and oral Psicoglut (Glutamine) (30 g/ d) (Group B), subjects with SBS reduced their requirement for IPN volume (-7.7 L/wk), IPN caloric content (-5751 kcal/wk), and weekly frequency of IPN administration (-4.2 d/wk).
