|Atypical Anorexia Nervosa||Other: Individualized Caloric Refeeding (ICR) Other: Higher Calorie Refeeding (HCR)||Not Applicable|
Atypical Anorexia Nervosa (AAN) is a new diagnosis describing patients with malnutrition and significant weight loss yet "normal" weight. These patients responded poorly to HCR, the superior refeeding treatment in the parent trial, which was designed for low-weight patients with typical AN. The proposed trial will examine the safety and efficacy of a new treatment for AAN with the potential to improve treatment outcomes for this diverse and growing patient population. The major finding motivating the proposed trial is that participants with AAN gained weight 40 percent slower and required 3.0 additional days in hospital to restore medical stability on HCR, as compared to AN. The research team has developed Individualized Caloric Refeeding (ICR), which doses calories to weight consistent with other pediatric treatments (e.g. medication).
The primary purpose of the proposed trial is to compare the efficacy and safety of ICR to the new standard of care (HCR) in hospitalized patients with AAN. The investigators hypothesize that ICR will restore medical stability faster than HCR with no increase in electrolyte abnormalities. After hospitalization, the major barrier to care in AAN is lack of consensus on clinical remission and whether these formerly overweight patients should gain weight to recover. The research team will examine metabolic, hormonal and psychological markers during long-term follow-up, toward the goal of developing a definition of clinical remission in AAN.
Design Summary: Randomized controlled trial in N=74 participants age 12-24 with AAN, consented upon hospital admission, randomly assigned to ICR or HCR, followed daily in hospital and at 3, 6, 9 and 12 mo.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||74 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||Participants will be recruited upon hospital admission at the University of California, San Francisco (UCSF) and Stanford and randomly assigned to Individualized Caloric Refeeding (ICR) or Higher Calorie Refeeding (HCR) for the duration of the hospitalization. Treatment ends at hospital discharge with open follow-up for one year. Participants followed daily in hospital and at 3mo, 6mo, 9mo, and 12mo post-discharge.|
|Masking:||None (Open Label)|
|Masking Description:||Treatments are not to be blinded, since both the patients and clinicians who work with this population are highly skilled at estimating kcal and would be able to determine group assignment by simply viewing meal trays.|
|Official Title:||Renewal of the Multi-center Randomized Controlled Trial of Refeeding in Anorexia Nervosa|
|Estimated Study Start Date :||September 2021|
|Estimated Primary Completion Date :||November 2024|
|Estimated Study Completion Date :||April 14, 2026|
Experimental: Individualized Caloric Refeeding (ICR)
Starting 50 kcal/kg/d, increasing by 200 kcal/d to goal
Other: Individualized Caloric Refeeding (ICR)
Meal-based refeeding in hospital, starting at 50 calories per kilogram of body weight, and increasing by 200 calories per day until caloric goal achieved
Other Name: ICR
Active Comparator: Higher Calorie Refeeding (HCR)
Starting 2000 kcal/d, increasing by 200 kcal/d to goal
Other: Higher Calorie Refeeding (HCR)
Meal-based refeeding in hospital, starting at 2000 calories per day, and increasing by 200 calories per day until caloric goal achieved
Other Name: HCR
- Time to Achieve Medical Stability in Hospital [ Time Frame: Inpatient hospitalization from day of admission to day of discharge, average 1-2 weeks ]Medical stability will be adjudicated by a five-point index: (1) 24 hour heart rate of 45 beats/min or more, (2) systolic blood pressure of 90 millimeters of mercury (mmHg) or more, (3) temperature of 35.6° C or more, (4) orthostatic increase in heart rate of 35 beats/min or less, (5) orthostatic change in systolic blood pressure of 20 mmHg or less.
- Incidence of low serum electrolytes during refeeding in hospital [ Time Frame: Inpatient hospitalization from day of admission to day of discharge, average 1-2 weeks ]Incidence of low electrolytes will be defined as: (1) hypophosphatemia less than 3 milligrams per deciliter (mg/dL), (2) hypomagnesaemia less than 1.8 mg/dL, and (3) hypokalemia less than 3.5 milliequivalent per liter (mEq/L) during hospitalization.
- Percentage median BMI (mBMI) Over 12 Months [ Time Frame: 12 months post-study hospitalization ]Measured BMI will be divided by the mBMI for age and sex per national growth data to give the percentage mBMI.
- Eating Disorder Examination Questionnaire (EDE-Q) Score Over 12 Months [ Time Frame: 12 months post-study hospitalization ]The EDE-Q will be self-administered; scores range from 1 to 6, with higher scores indicating greater severity and a worse outcome.
