Clinical Trials - We Need Better Treatments

I apologize for taking so long to write an article. I, myself, have had a rough year like everyone else seemed to in the GP Community. I lost A LOT of friends last year in my support groups, people I started support groups with, and people I talked to regularly. I logged into Facebook this morning to check on my groups, as I've been sick with pneumonia on top of Gastroparesis for the past week and a half (before that, my husband and I were passing a respiratory virus back and forth) and found another one of my friends had died. She was someone I've known since I first started advocating for Gastroparesis. She was apart of the handful of women who helped start Gastroparesis support groups and build up the Gastroparesis Community. I wanted to dedicated this article to her, and the other friends I've lost. Last year, we lost 48 people. This year, so far, I think the total is four or five people. It's heartbreaking. We need better treatments. Having invasive "treatments" like feeding tubes, which can cause infections and worse, and then on the other end of the spectrum, medicine like Reglan, which can lead to irreversible, neurological disorders. We need medication to help our stomachs, to keep them from cramping so badly, to help them contract.

We need SOME kind of help. I'm so upset at watching my friends suffer and die. I get scared every time I throw up, wondering if it's going to be the last time - if this is the time I'm going to rupture my esophagus and die. I get panic attacks logging on to Facebook, scared I might read another one of my friends has passed away, which always upsets me right away, not only because they passed, but I feel like when I take breaks from Facebook, that I'm letting them down for not being online. I feel like I didn't get to say what I wanted to say to them before they passed. Most of that is on me. I've been not terrified to log into Facebook, but just



If you are interested in joining a clinical trial for Gastroparesis, The National Institute of Diabetes, Digestive, and Kidney Diseases are having people sign up for one now: https://www.niddk.nih.gov/health-information/digestive-diseases/gastroparesis/clinical-trials


Centerwatch has a long list of clinical trials that need volunteers as well: https://www.centerwatch.com/clinical-trials/listings/condition/72/gastroparesis/


ClinicalTrials.gov has a current trial happening as we speak: https://clinicaltrials.gov/ct2/show/NCT03500354

The Trial Says,
"Brief Summary:

Gastroparesis is a chronic, morbid and costly neuromuscular disorder of the stomach characterized by delayed gastric emptying in the absence of gross structural abnormalities. The periprandial symptoms associated with this disease can preclude adequate oral intake and often lead to weight loss and nutritional deficiencies 1. These manifestations are largely due to impaired gastric accommodation of meals and delayed transfer of food boluses from the stomach into the duodenum2. Consequently, the investigators hypothesize that dietary supplementation with a low volume, hypercaloric nutritional drink can help prevent malnutrition, decrease symptom burden and improve health-related quality of life in this population. Due to the paucity of such a supplement, the investigators developed a novel nutritional drink designed to maximize tolerability in patients with gastroparesis . This nutritional drink was tested on healthy volunteers (phase I) and passed the palatability test. The investigators now aim to test the tolerability of this drink on gastroparesis patients.

Condition or disease Intervention/treatment Phase
Gastroparesis Dietary Supplement: Nutrient drink Not Applicable

Detailed Description:

Primary objective:

To evaluate the safety and tolerability of the nutritional drink in gastroparesis patients.

Secondary objective:

To evaluate the efficacy of the nutritional drink in gastroparesis patients.

Study Procedures This study will be a pilot, open-label, trial in gastroparesis patients. A total of 20 patients will be recruited from the gastroenterology gastroparesis clinic. If the volunteer meets eligibility criteria, a co-investigator will contact the patient to schedule a study visit with a nutritionist and obtain a written consent. The contact and screening information of patients that are successfully recruited will be documented, placed in the participant's study folder and stored in a locked cabinet in the research unit. Any information documented during the screening process for patients who do not meet basic eligibility criteria or do not wish to participate will be immediately destroyed.

Patients will be given enough supply of the nutrition drink for (4 weeks) and asked to consume 200 ml of the drink three times daily. A follow-up call will be scheduled on day 2, day 7 and at the end of the study to make sure patients are tolerating the drink. Participants will be allowed to consume water and food as desired during the study period but will need to maintain an accurate food diary for at least one week prior to enrollment and during the study (at 2 weeks and at 4 weeks) along with weight measurements at baseline, 2 weeks, 4 weeks and 6 weeks. The participants will be asked to complete a palatability questionnaire. They will also complete the Gastroparesis Cardinal Symptom Index (GCSI) daily diary and the PROMISE scale prior to enrollment as a baseline for their symptoms and again at 2 weeks, 4 weeks (end of the study) and 6 weeks. Changes in these scales from baseline will determine the efficacy and possibly side effects of the nutritional drink.

Study duration and number of study visits required of research participants:

4 weeks, initial study visit with a nutritionist for screening and consenting followed by 3 follow-up phone calls on day 2, day 7 and at 4 weeks (the end of the study) and a final study visit at 6 weeks (2 weeks after finishing the study)

Heidelberg pH Test

What is a Heidelberg pH Test? A friend mentioned he had this test on a comment on one of my pages on Facebook. I had never heard of this test before, so I wanted to do some research into it. As it turns out, this test really does encompass a wide range of things it tests for. It reminds me of the Smart Pill test, in a way, but broadened. So, after reading about it, below is the information I found concerning the test.




According to Heidelberg Medical,

"What is a Heidelberg pH Test?

The Test will accurately verify the presence of a common Digestive Disorder

The Physician will require a complete Medical History before the Test

There will be a Transceiver that is placed over the Patient’s stomach during the test.

The pre test instructions will help achieve the most accurate results.

There is no discomfort during a Heidelberg pH test. Patients are relaxed and comfortable.

Remember to grab a good old fashioned distraction to pass the time.

Due to wireless interference, cell phones and personal electronic devices may need to be powered off.

The results are immediate so the Physician may have the post test consultation the same day.

Heidelberg pH Diagnostic Test will accurately verify the presence of low stomach acid production, high stomach acid production, no acid in the stomach, Dumping Syndrome, Acute or sub Acute Gastritis, Heavy Mucus in the stomach, and Pyloric insufficiency.

The Test is accomplished by measuring the time it takes for the acid producing cells (Parietal Cells) in the stomach to produce the required Hydrochloric acid. The strength of the acid (pH) is also measured during the test.

Patients are required to complete a consent form for the Physician’s Office Staff. If you have reservations about having a pH test, please discuss them with the Physician. Mental anguish and stress will only alter the test results.

The Technician will calibrate the pH Capsule to ensure it accurately records the pH values. The Technician will then place a transceiver over the Patient’s stomach. The transceiver receives and transmits the information from the pH Capsule and sends it wirelessly to the computer where the information is displayed. The nurse will rinse the pH Capsule and give it the Patient to swallow with a sip of water.

There is no discomfort during a Heidelberg pH Test. Patients are asked to relax and get comfortable while the test is being done. Remember to grab a good old fashioned distraction to pass the time.

Results are ready for the Physician to review as soon as the Technician ends the Test. Many Physicians opt to have a post test consultation as soon as the test is complete. In many cases the doctor will establish a treatment protocol on the same day. In many instances, after testing and treatment, patients stated that they feel better and healthier in just two or three days.


Unlike other procedures, the Heidelberg pH diagnostic test is an in-office procedure that does not require sedation or the use of a stomach tube.

There is no trauma or discomfort associated with our test, and the results of the Heidelberg test are available to the doctor as soon as the test is complete. Why go through an unpleasant procedure like the nasal-gastric intubation, when you can have a Heidelberg Diagnostic test?




Physicians

As the examining Physician, you will always hear a wide spectrum of complaints from your patients. By adding The Heidelberg pH Diagnostic System to your method of testing, you can be assured of having a comprehensive overview of the patients’ first stage of digestion. We believe you will find that the results of your treatment protocols will be enhanced from the pH data, which this test provides. There is no guess work involved and the test results are reproducible.

When the total digestive system is in pH balance, You can expect higher levels of conversion and absorption of ingested foods and medications. In addition, you can expect an appreciable enhancement of the patient’s immune systems! This is a very encouraging step for all aspects of successful treatment! The digestive system supports the immune system. Without proper conversion and absorption of the foods, medications, and supplements, the immune system cannot function at its optimum level. The Heidelberg pH Diagnostic System can be used to bring the first stage of digestion to its optimum performance level for good conversion and absorption.





Researchers

The Heidelberg Diagnostic technology has been used over the past 39 years by Researchers and Pharmaceutical companies throughout the world.

Some of the recognized Pharmaceutical companies are; Pfizer (Global Research and Development), Boehringer Ingelheim, Tap Pharmaceuticals, Bayer, Merck, Glaxo, SmithKline and Novo Nordisk (Denmark).

When a pharmaceutical company develops a new medication, they use the Heidelberg diagnostic system to perform pharmacokinetic studies to determine the activity of the medication on the human body. This is where, in many cases, the Heidelberg technology becomes a valuable research tool, in assuring the safety of a newly developed medication. These studies are use to determine bodily absorption, distribution, metabolism and excretion of drugs.

Before testing newly developed medications on humans, many pharmaceutical companies test their products on animals. Tests on animals include the use of swine, dogs, monkeys, etc. As part of their approval process, the Food and Drug Administration (FDA) requires testing of many newly developed medications in humans before being approved for use in the open market.

Researchers in many medical teaching colleges and research facilities use the Heidelberg Diagnostic system for testing the side effects of drugs. They also monitor the body pH when testing new vaccines to counter the effect of contagious diseases.

The Pharmaceutical Grade Heidelberg Diagnostic system can be configured to test from 1 to 8 subjects at the same time without interaction. Custom built systems can be configured to test 16 or more subjects at the same time without interaction.

Our current Bibliography of research studies contains over 150 published studies, conducted by researchers, pharmaceutical companies, clinicians, medical teaching colleges and hospitals. A copy of these studies are available upon request.

Heidelberg pH Diagnostic Systems

The Portable Heidelberg pH Diagnostic System is an innovative system that is ideal for any busy practice, where a stationary desktop computer system would have it’s limitations. It can be transported from one room to another, or from one facility to another. The dedicated laptop computer, and a compact micro-jet printer, is placed on a movable medical grade laboratory cart that has lockable casters, with an Uninterrupted Power Supply (UPS system), with an 8 foot electrical cord. The laboratory cart has a built security feature that allow you to safely store your computer, printer and other equipment in a lockable storage cabinet, when they are not being used. The portable Heidelberg pH Diagnostic System can be used for single, or multiple, patient pH Diagnostic Testing.

The standard clinical grade Heidelberg Diagnostic systems can be configured to test from 1 to 8 patients simultaneously without interaction. Our custom built systems can be configured to test from 1 to 16 patients at the same time without interaction.

Exclusivity

The FDA requires that system operators (nurses or technicians) be training in the use of the system and do testing under the supervision of a licensed physician. Third party reimbursement depends on individual states and individual insurance companies, and the form in which the CPT coding is submitted.

The Heidelberg pH Capsule package insert reads: CAUTION: Federal law restricts this device to sale only by, or on the order of a qualified physician. A patient history and examination are required before administering this diagnostic test.

Example: Crohn’s Disease, or any history of intestinal blockage, adhesions and/or history of bleeding.

Clinical Trial to Test Efficiency of IV Hemin for Gastroparesis

Clinical Trial to Test Efficiency of IV Hemin for Gastroparesis

Gastroparesis is a syndrome marked by slow gastric emptying and symptoms such as nausea, vomiting, bloating, early fullness and abdominal pain. Although long associated with type 1 diabetes and now, increasingly, with type 2, the cause in many cases remains unknown.

But gastroenterologist Gianrico Farrugia, M.D., stresses that in the last few years, scientists at Mayo Clinic and elsewhere have made marked progress in understanding the pathological mechanisms underlying the disorder. Much of the current research focuses on the interstitial cells of Cajal (ICC), which are needed for normal stomach emptying.

"The ICC act as intestinal pacemakers for smooth muscle function," he says. ''They also amplify neuronal signals, act as mechanosensors and set the smooth muscle membrane potential gradient. Both human and animal models demonstrate loss of these cells in diabetic and idiopathic gastroparesis."

Normal gut function requires a balance between processes that injure ICC and processes that generate and maintain them. In people with diabetic gastroparesis, the balance shifts toward factors that damage ICC, including relative insulinopenia and deficiency of insulin-like growth factor-1 (IGF-1), both of which can cause smooth muscle atrophy.

Dr. Farrugia says a critical factor is oxidative stress resulting from low levels of heme oxygenase-1 (HO-1), an important protector against oxidative injury.

"When the mechanisms that normally counteract oxidative stress are impaired, especially upregulation of heme oxygenase-1, ICC are lost and gastric emptying is delayed. In mouse models, restoring HO-1 prevents and even reverses these cellular changes and restores normal gastric function."
Macrophage switching

In the stomach wall, HO-1 expression occurs in a particular subset of macrophages — CD206-positive M2 macrophages — whose cytoprotective effect on ICC appears related to the production of small amounts of carbon monoxide.

Dr. Farrugia says, "When the upregulation of HO-1 is lost, M2 macrophages are replaced by proinflammatory M1 macrophages. These cells, which do not produce carbon monoxide, are associated with ICC damage and the development of delayed stomach emptying. Thus, the upregulation of HO-1 in M2 macrophages seems critical to the prevention of diabetes-related gastroparesis."
Clinical trials

In mouse studies, hemin, a biological product of red blood cells, has been shown to boost the production of HO-1, thereby reducing oxidative stress, allowing repair of the ICC network and normalizing gastric function. Now, Dr. Farrugia and colleague Adil E. Bharucha, MBBS, M.D., are recruiting patients for the first randomized controlled clinical trial to determine whether intravenous hemin therapy is equally beneficial for people with gastroparesis.

"The hope is that this clinical trial may lead to an effective medication for gastroparesis — one that doesn't just manage symptoms as prokinetics do, but that actually targets the cause of the disease."

The need for better treatments is especially critical now, Dr. Farrugia says, because the incidence of gastroparesis is increasing. The number of hospitalizations for the disorder grew by nearly 158 percent from 1995 to 2004. "The vast majority of patients are young women of childbearing age. This disease causes tremendous disruption in patients' lives and in the lives of their families, and none of the treatments we have are ideal."
