CVID Enteropathy Clinical Trial
Official title:
An Open-Label Phase I/II Pilot Study to Assess the Safety/Tolerability and Efficacy of Ustekinumab for Symptomatic Gastrointestinal Inflammation Associated With Common Variable Immunodeficiency
Background:
- Some people with Common Variable Immunodeficiency Disease (CVID) have gastrointestinal
inflammation. This can cause diarrhea, weight loss, and not being able to absorb nutrition
from food. Researchers want to see if the drug ustekinumab can help these problems. This drug
blocks some proteins that cause inflammation.
Objective:
- To test the safety and efficacy of the drug ustekinumab for people with CVID with
gastrointestinal inflammation.
Eligibility:
- Adults ages 18-75 with CVID. They must have chronic diarrhea, have unintentionally lost
weight in the last year, and/or need to use nutritional supplements to maintain their weight.
Design:
Participants will undergo the following screening studies to make sure that this study is a
good fit for your medical situation, and to make sure it is safe for you to receive the study
medications tests, including tests for HIV and hepatitis . This will be done as an inpatient
at the NIH Clinical Center and takes about 5-6 days:
- Participants will be screened with:
- Medical history
- Physical exam
- Blood tests, including tests for HIV and hepatitis.
- Stool tests, including a timed 48 hour collection for fat malabsorption and a 24 hour
collection for protein malabsorption
- Urine tests, including a pregnancy test for any women with the ability to have a child
- Chest CT scan to look for infection
- D-xylose testing, which involves drinking a sugary solution and then having a blood
sample drawn to test carbohydrate (sugar) malabsorption
- Hydrogen breath testing for test for small intestinal bacterial overgrowth (SIBO) this
test also involves drinking a sugary solution and then collecting breath samples
- Upper endoscopy (EGD) and/or colonoscopy to look at the lining of the GI tract and take
biopsies for testing. This will be done under sedation by a qualified
gastroenterologist.
Participants who complete screening and meet all criteria will then return to the NIH
Clinical Center for the following visits:
- First Treatment Visit (1 clinic day): Medical history, physical exam, measurement of
vital signs and weight, review of medications, and an assessment of number and
consistency of stools each day. A pregnancy test for women of childbearing potential. A
nurse will give you three shots of 90 mg ustekinumab (270 mg total dose) by very small
needles injected under the skin, and then observe you for 1 hour.
- Week 8 Treatment Visit (1 clinic day): Medical history, physical exam, measurement of
vital signs and weight, review of medications, and an assessment of number and
consistency of stools each day. Blood, urine and stool samples will be collected. A
pregnancy test for women of childbearing potential. A nurse will give you one 90 mg dose
of ustekinumab by a very small needle injected under the skin, and then observe you for
1 hour.
- Week 16 Treatment Visit (1 clinic day): Medical history, physical exam, measurement of
vital signs and weight, review of medications, and an assessment of number and
consistency of stools each day. Blood, urine and stool samples will be collected. A
pregnancy test for women of childbearing potential. A nurse will give you one 90 mg dose
of ustekinumab by a very small needle injected under the skin, and then observe you for
1 hour.
- Week 24 Treatment and Mid-point Evaluation Visit (4-6 inpatient days): Medical history,
physical exam, measurement of vital signs and weight, review of medications, and an
assessment of number and consistency of stools each day. Blood, urine and stool samples
will be collected, including repeating the d-xylose carbohydrate malabsorption testing,
the 24 hour stool collection for protein malabsorption and the 48 hour stool collection
for fat malabsorption. A pregnancy test for women of childbearing potential. A nurse
will give you one 90 mg dose of ustekinumab by a very small needle injected under the
skin, and then observe you for 1 hour.
- Week 32 Treatment Visit: Medical history, physical exam, measurement of vital signs and
weight, review of medications, and an assessment of number and consistency of stools
each day. Blood, urine and stool samples will be collected. A pregnancy test for women
of childbearing potential. A nurse will give you one 90 mg dose of ustekinumab by a very
small needle injected under the skin, and then observe you for 1 hour.
- Week 40 Treatment Visit: Medical history, physical exam, measurement of vital signs and
weight, review of medications, and an assessment of number and consistency of stools
each day. Blood, urine and stool samples will be collected. A pregnancy test for women
of childbearing potential. A nurse will give you one 90 mg dose of ustekinumab by a very
small needle injected under the skin, and then observe you for 1 hour.
- Week 48 ...
The purpose of this study is to assess the safety/tolerability and efficacy of using
ustekinumab in subjects with common variable immunodeficiency CVID or selective IgG subclass
deficiency (functional agammaglobulinemia) who have associated symptomatic gastrointestinal
inflammation (CVID enteropathy). Ustekinumab (a Food and Drug Administration [FDA] approved
drug) is a monoclonal antibody to interleukin (IL)-12/23p40. CVID is a clinically
heterogeneous disorder characterized by decreased serum immunoglobulin IgG and IgA levels. In
addition to chronic or recurrent pyogenic sino-pulmonary infections, many patients develop
non-infectious gastrointestinal manifestations that can be disabling or fatal. Currently
there is no standard therapy for the associated gastrointestinal disease outside of empiric
nutritional intervention for weight loss, anti-diarrheal agents, and non-specific
anti-inflammatory agents.
Recently, gut inflammation complicating functional hypogammaglobulinemia due to CVID and
selective IgG subclass deficiency has been characterized as a T helper type 1 (Th1)
inflammatory response, with excess IL-12 cytokine production associated with diarrhea and
weight loss as well as reduced D-xylose absorption and steatorrhea. This protocol aims to
test specific anti-IL-12 therapy in this patient group. It has been previously shown that
therapy targeted to IL-12 successfully treated the Th1 gut inflammation of Crohn s disease
(CD). Ustekinumab, a monoclonal antibody to the p40 subunit of IL-12 and IL-23, is FDA
approved for the treatment of moderate to severe plaque psoriasis, active psoriatic
arthritis, and more recently, moderately to severely active CD. This protocol is designed to
measure the safety of ustekinumab in patients with functional hypogammaglobulinemia and CVID
enteropathy, as well as measure effects on symptoms, gut function, expression of immune cell
surface markers, production of cytokines and global gene expression from blood and gut
mucosal mononuclear cells, and the gut microbiota.
Patients with CVID and selective IgG subclass deficiency with gastrointestinal symptoms of
malabsorption, maldigestion, and chronic diarrhea will be enrolled into this study. Subjects
(up to a total of 10 individuals) will receive a treatment dose of 270 mg (3 doses of 90 mg
either single-use prefilled syringe or single-use vial, depending on availability) will be
injected subcutaneously in subjects by qualified nursing staff on the Day 0 study visit.
Subjects will then receive a follow up treatment dose of 90 mg at Week 8, Week 16, Week 24,
Week 32 and Week 40 and be followed for a total of 48 weeks.
Subjects will have study procedures prior to treatment and 48 weeks post-treatment, these
include upper and/or lower endoscopies, to measure changes in immune responses and studies to
evaluate physiologic measures of gut function at 48 weeks, as well as routine safety
monitoring throughout the study. Gut absorption tests will be performed at the Week 24 visit.
Variables will include safety (adverse event rate), clinical (weight, stool frequency,
results of gut absorption tests), and laboratory (lymphocyte and cytokine assays) parameters
for descriptive summary statistical analysis (n, mean, median, standard deviation, minimum
and maximum range).
