Hydroxychloroquine and Metabolic Outcomes in Patients Undergoing TPAIT

April 6, 2022 updated by: The Cleveland Clinic

Hydroxychloroquine and Metabolic Outcomes in Patients Undergoing Total Pancreatectomy and Autologous Islet Transplantation: A Clinical, Molecular, and Genomic Study

This will be a pilot, 12-month phase II, open label, randomized, two-arm, single-blinded, placebo-controlled, parallel clinical trial of individuals undergoing TPAIT (Total Pancreatectomy and Autologous Islet Transplantation) for treatment of chronic pancreatitis (CP). The two study arms consist of HCQ-treated (Hydroxychloroquine) and placebo-treated individuals. The purpose of this study is to investigate the effects of HCQ administration compared to placebo on islet cell function post-autologous transplantation.

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A compelling level of evidence exists on the effects of the innate immunity-driven inflammation on the decline of functional beta cell mass in the autologous transplant setting. The investigators hypothesize that HCQ administration during the peri-transplant period will preserve islet mass and improve islet cell function in TPAIT by reducing inflammation. The investigators specifically aim to demonstrate a higher stimulated C-peptide level as well as greater glucose control in response to mixed meal tolerance testing (MMTT) at 6 and 12 months following TPAIT in patients treated with HCQ compared to placebo. A better response in the HCQ arm suggests improved islet survival and metabolic performance, potentially facilitating higher rates of insulin independence.

HCQ administration:

Arm 1 (n=5): Subjects will receive a pre-transplant HCQ 200 mg daily dose 30 days prior TPAIT followed by HCQ use for an additional 3 months post-surgery.

Arm 2 (n=5) subjects will receive placebo treatment following the same schedule as in Arm 1.

Exploratory mechanistic studies:

All subjects will undergo a MMTT to assess islet cell function at 6 and 12 months following TPAIT (in addition to MMTT pre-surgery performed as standard of care, and whose results will be used for pre-randomization in this pilot). Baseline metabolic tests obtained too early after surgery may not be indicative of islet function, due to insulin supporting therapy administered for several weeks after transplantation. Also, compelling data indicate that stabilization of islet function may require up to 1 year to occur. Blood glucose and C-peptide serum levels will be measured in peripheral blood samples immediately prior and subsequent to MMTT. The research coordinator will contact the subjects at 3, 6 and 12 months for interview on the course of follow up and will assist in scheduling the 6 and 12-month appointments for MMTT.

Mitochondrial Function and Metabolic Outcomes in TPAIT:

Mitochondrial efficiency is important in the setting of TPAIT, where increase in metabolic demand and decrease in oxygenation have been established. The investigators will assess mitochondrial efficiency by measuring rates of mitochondrial respiration and glycolysis. These measures will be obtained on islets procured for donation and after islet isolation. Small amounts of digest left after islet isolation, that would normally be discarded, will be used for this portion of the study. The islets from the digest will be collected and will undergo extracellular efflux analysis through the Seahorse XF analyzer for mitochondrial function assessment. Commercially available normal human islet cells for experiments will be used as control. Controls will be compared simultaneously with islets isolated from study subjects.

Genome-wide Gene Expression in TPAIT Patients:

On the genomic level, several genetic pathways have been implicated in islet cell function and survival. The genetic profiles of islet cells from CP patients undergoing TPAIT have not been evaluated yet. The investigators aim to build an RNA-gene sequence database for islet cells of CP patients undergoing TPAIT, specifically targeting genes previously identified as key players in islet function. Small amounts of digest from the procedure used for isolating islets, and what remains in the circuit after the isolation process is complete, that would normally be discarded, will also be used for islet gene expression assessment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Quotient of Stimulated C-peptide/Glucose Level Normalized for IEQ/Kg Infused in Response to MMTT
Time Frame: 12 months
HCQ-treated compared to placebo arm. This outcome measure was reported in Mean and Standard deviation looking at C peptide/glucose secretion at 90 mins during mixed meal test adjusted for IEG/Kg (islet cell equivalency) infused to the patient.
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
C-peptide AUC Response to MMTT
Time Frame: 12 months
HCQ-treated compared to placebo arm. We used a standard, 5 hour Mixed meal tolerance test (MMT). Blood draws were taken every 15 mins for the first hours, then every 30 mins the second hour, then hourly until completion.
12 months
Ratio of C-peptide AUC to Glucose AUC in Response to MMTT Adjusted for Infused Islet Cell Mass
