Clinical Trial Summary

This study seeks to investigate the safety, tolerability and efficacy of CT38, an experimental peptide administered by subcutaneous infusion, in the treatment of ME/CFS patients.

Description:

Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS) is a complex disorder that may be triggered by infection or other stressors (e.g., emotional or physical trauma, immune activation, chemical exposures). Its hallmark is a reduced capacity for physical and mental activity manifest as profound fatigue along with a cascade of debilitating symptoms (including pain, cognitive dysfunction, orthostatic intolerance, sensitivities, and irregularities of the autonomic, immune and metabolic systems) that worsen with activity (referred to as post-exertional malaise or PEM), are not improved by sleep, and can persist for years. Patients are often unable to handle the activities of daily living and experience a loss of career and a very poor quality of life. There are no established diagnostic tests or approved therapeutics for ME/CFS.

The cause of ME/CFS is not known. It has been postulated that ME/CFS could arise from the up-regulation of a specific receptor (CRF2) in those parts of the brain that govern the sensitivity of the stress response. This configuration would invoke a major response to a minor stimulus, ultimately leading to neuroendocrine, autonomic, immune and metabolic abnormalities that are commonly observed. There is no animal model of ME/CFS, but overstimulating CRF2 in healthy rats, induces signs and symptoms consistent with the disease in humans; while down-regulating it, via CT38 (an experimental peptide), eliminates the ability to stimulate these signs and symptoms. Hypothesis: Utilize CT38 to down-regulate CRF2 to restore a normal stress response, and potentially eliminate disease signs and symptoms.

The study will enroll 18 patients, who meet the Fukuda and Canadian criteria for ME/CFS, and treat them with various doses of CT38.

The primary endpoint will be the change in the average total daily symptom score (TDSS), over 28-day periods immediately prior to the first treatment (pre-treatment) and immediately prior to exit from the trial (post-treatment). The TDSS is the sum of 13 individual symptom scores, each recorded daily by the patient on a 6-point scale (0=none, 1=very mild, 2=mild, 3=moderate, 4=severe, 5=very severe). The individual symptoms included fatigue, muscle/joint pain, sleep issues (e.g., un-refreshing sleep, difficulty falling or staying asleep, excessive sleepiness), cognitive issues (e.g., slow information processing, memory difficulties, inability to concentrate/focus, attention deficit), orthostatic intolerance (e.g., dizziness, spatial disorientation, light-headedness, feeling faint), body temperature perceptions, flu-like symptoms (e.g., sore throat, tender lymph nodes, swollen glands, fever, chills, sinus/nasal problems), headaches or sensory sensitivities (to light, sound, smell, touch, taste), shortness of breath, gastrointestinal problems (e.g., nausea, stomach/abdominal pain, diarrhea), urogenital problems (e.g., frequent urination), anxiety and depression.

The secondary outcomes will assess general health status (determined by Short-Form 36, or SF-36), as well as safety assessments.

Acceptable methods of birth control during the study are intrauterine device, diaphragm with spermicide, contraceptive sponge, condom or vasectomy. Oral contraceptive pills may not be used as the sole method of contraception because the effect of CT38 on the efficacy of oral contraceptive pills has not yet been established

• Stated willingness to comply with all study procedures and remain available for the study duration

• Have mobile (smart) phone and access to the internet

Exclusion Criteria:

• Alternate medical or psychiatric illness that could explain the ME/CFS symptoms

• Unwilling or unable to perform an exercise test

• Active or uncontrolled co-morbidities which in the opinion of the PI may interfere with the ability of the patient to participate in the study. Co-morbidities may include acute infection, Crohn's disease, diabetes mellitus (Type 1 or Type 2, evidenced by a history of glycated hemoglobin (A1C) > 7 at any time), Guillain-Barre syndrome, lupus, multiple sclerosis, myasthenia gravis, rheumatoid arthritis, or other such diseases that may be exclusionary. Particularly conditions or medications that cause immunodeficiency or immunosuppression will be excluded. Examples of such conditions can be found in the tables "Causes of Secondary Immunodeficiency" and "Some Drugs that Cause Immunosuppression" in the "Merck Manual"

• Pregnancy, or while breast feeding. Women should not be enrolled within 6 months of giving birth and within 3 months of cessation of breast feeding

• A Body Mass Index > 35

• Cigarette smoker or former smoker who has smoked within 6 months of the start of the study

• Living at an altitude that is more than 1,000 feet (lower or higher) from the study site (which is 4,500 feet above sea level)

• History of:

• Major depression with psychotic or melancholic features before the diagnosis of ME/CFS, or active depression (major depression with psychotic or melancholic features) as determined by self-report

• Untreated endocrine diagnoses including hypothyroidism (Hashimoto's, etc.), Grave's disease, adrenal insufficiency, hypogonadism (testosterone deficiency), diabetes mellitus or insipidus

• Acute infection within the past 30 days

• Within the last 3 years, any significant head injury, e.g., concussion with loss of consciousness, brain surgery, an automobile accident with head/neck injury, other traumatic brain injury

• A supra-ventricular tachycardia or ventricular tachycardia, e.g., atrial fibrillation or flutter, paroxysmal atrial fibrillation, junctional tachycardia, ventricular tachycardia

• Severe baseline hypotension defined as rested sitting systolic BP < 100 mmHg or rested sitting diastolic BP < 60 mmHg

• Renal impairment based upon the local lab normal estimated glomerular filtration rate (eGFR) (drug is cleared by passive renal filtration)

• Known hypersensitivity or clinically significant allergies to tromethamine or Tween 80 (both excipients in the drug product)

• Substance abuse in the past 12 months as determined by self-report

• Improvement in overall ME/CFS symptoms as a result of any treatment intervention in the past 3 months
