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.
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.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.
Criteria about it usually ask for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
