Researchers are investigating how drinking an enteral nutrition EN formula by mouth before getting a feeding tube Gtube affects tolerance to feeding through the tube in people with amyotrophic lateral sclerosis pALS. ALS is a progressive disease that often leads to swallowing difficulties, weight loss, and malnutrition. This study aims to assess whether better nutrition before Gtube placement slows disease progression and reduces gastrointestinal GI symptoms related to feeding intolerance. The study involves a single group of participants who will all receive the intervention. It has three stages a pre-intervention period where usual diet and symptoms are recorded phase I where participants drink a plant-based EN formula Kate Farms 1.4 Standard for about two weeks to meet their nutritional needs and phase II where, after Gtube placement, participants will feed via the tube with the same formula and amount for about two weeks. Data on dietary intake and GI symptoms will be collected weekly throughout. Participants will complete food diaries and GI symptom surveys regularly, with support from caregivers if needed. Researchers will measure GI symptoms using a standardized scale, dietary intake, body mass index BMI, and functional status using the ALS Functional Rating Scale. The study will analyze how nutrition relates to disease progression and feeding intolerance over a total of approximately five weeks. Weekly data collection and safety monitoring will be done by phone and email, with clinical teams recording any significant GI events.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | Study: Oral Pre-Exposure to Enteral Nutrition Formula | Current Practice: Direct Tube Feeding Without Oral Pre-Exposure |
|---|---|---|
| What is it? | Participants with ALS take the enteral nutrition formula by mouth for a period before the feeding tube is placed, then continue the same formula via gastrostomy tube. The goal is to see whether oral pre-exposure affects formula intolerance once tube feeding starts. | Tube feeding with an enteral nutrition formula is usually started after gastrostomy tube placement in ALS without prior oral exposure to the formula. The formula is first given through the tube under medical supervision. |
| Role in trial | This is the only intervention being studied: participants are exposed to the formula orally before tube feeding begins. No control or comparator arm exists. | Represents standard clinical practice outside the trial: people with ALS requiring a gastrostomy tube start formula feeding through the tube, without an oral pre-exposure period. |
| Primary use or goal | To determine if consuming the formula by mouth before tube placement decreases symptoms of feeding intolerance after tube feeding starts in ALS. | To provide nutritional support in ALS by directly initiating formula feeding via gastrostomy tube, aiming to reduce weight loss and malnutrition. |
| How is it given or performed? | Participants first drink the formula (medical food) by mouth in the weeks before planned tube placement, then the same formula is given through the new gastrostomy tube after the procedure. | Standard formula feeding begins only after gastrostomy tube is placed. The formula is administered via the tube under medical supervision, typically without prior oral intake of the formula. |
| Broader evidence or maturity | The efficacy of pre-exposure to tube feeding formula via mouth for reducing formula intolerance is not yet established in ALS. This trial aims to generate first evidence in this clinical context. | Direct formula introduction after tube placement is supported by clinical guidelines and current practice as the standard approach for nutritional support in ALS, but feeding intolerance remains common. |
| Important limitations | The single-group design lacks a direct randomized comparator. The effect of oral pre-exposure on intolerance is not yet known, and external factors such as variability in formula tolerance among patients may influence outcomes. | Many people with ALS experience formula intolerance, and there is no established pre-exposure procedure to reduce symptoms. Definitions of feeding intolerance vary, making rates hard to compare between studies. |

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
Duration - 1 week
Participants maintain their usual food and drink intake while dietary intake and gastrointestinal symptoms are recorded.
Weekly data collection by phone or email
Duration - 2 weeks ± 2 days
Participants drink a plant-based enteral nutrition formula daily for about two weeks to meet their nutritional needs while continuing their current diet. Weekly dietary intake and gastrointestinal symptoms are monitored.
Weekly data collection by phone or email
Duration - 2 weeks ± 2 days
After Gtube placement, participants feed via the tube using the same enteral nutrition formula for about two weeks, maintaining their usual oral intake. Weekly dietary intake and gastrointestinal symptoms continue to be monitored.
