Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||13 Years and Over|
Inclusion Criteria:1. Males or females who are at least 13 years of age. 2. Willing and able to understand and sign informed assent/consent. Adolescents will need a parent or guardian willing and able to give consent. 3. Clinical diagnosis of epidermolysis bullosa (dystrophic, junctional or simplex). 4. History of chronic pruritus of at least 6 weeks in duration. 5. On the Screening Visit or Screening phone call, patients must have an NRS pruritus score of at least 5 on average itch score in the past 24 hours. 6. Female subjects must be of non-childbearing potential (ie, post-menopausal for at least 1 year, had a hysterectomy, or had a tubal ligation) or, if of childbearing potential, must have a confirmed negative urine pregnancy test prior to study treatment and be willing to use effective contraception for the duration of the trial. Effective contraception is defined as follows: oral/implant/injectable/ transdermal contraceptives, intrauterine device, condom with spermicide, or diaphragm with spermicide. Abstinence or partner's vasectomy is acceptable if the female agrees to use effective contraception if she decides to discontinue abstinence or to have sexual intercourse with a non-vasectomized partner. 7. Judged to be in good health based upon the results of a physical examination, medical history, and safety laboratory tests.
Exclusion Criteria:1. Have any medical condition or disability that would interfere with the assessment of safety or efficacy in this trial or would compromise the ability of the subject to travel to Stanford or to undergo study procedures or to give informed consent. 2. Have a history of sensitivity to any components of the study material. 3. Are females of childbearing potential who are unwilling to use adequate contraception or who are breast feeding. 4. Have any chronic or acute medical condition that, in the opinion of the investigator, might interfere with the study results or place the subject at undue risk. 5. Have chronic renal disease, i.e., serum creatinine greater than 2 times the upper limit of normal. 6. Have chronic liver disease. Subjects with hepatitis B and C who have normal liver function may be enrolled. 7. Have a current malignancy (such as Hodgkin's lymphoma, B or T cell lymphoma, or myeloma) or blood cell dyscrasia (e.g., polycythemia or myelofibrosis) that would lead to systemic chronic pruritus. 8. Have a history of thyroid cancer, thyroid nodules, inadequately treated thyroid disease, or abnormal TSH or free T4 at screening. 9. Have a history of abnormalities in adrenal or pituitary function (pituitary adenoma, adrenal insufficiency, or adrenal nodule). 10. Screening cortisol level < 3 mcg/dL. 11. Unevaluated abnormalities in cortisol, ACTH, or prolactin. 12. Have pruritus of psychogenic etiology (delusions of parasitosis, obsessive compulsive disorder and major depression) or neuropathic etiology (due to shingles, spinal cord injury or with neurologic deficit). 13. Have pruritus due to urticaria, drug allergy, or infection (such as pityriasis rosacea or tinea or active human immunodeficiency virus [HIV]). Note: Subjects with HIV who have undetectable viral load, and stable retro-viral therapy may enroll. 14. Have taken investigational medications within 30 days prior to Screening. 15. Are unwilling to discontinue specific medications that, in the view of the investigator may have significant interactions with the trial drug, for at least two weeks prior to initiation of study and throughout the study period (this includes miconazole, delavirdine, conivaptan, Clarithromycin, telithromycin, nefazodone, itraconazole, ketoconazole, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir). 16. Are unable or unwilling to maintain their current anti-itch and opioid-based pain medications at a stable dosage through the course of the two months of active treatment (including but not limited to opioid pain medications, antihistamines, and gabapentin) 17. Started or changed medications, creams, or emollients including over-the-counter (OTC) preparations or bath oil treatment specifically for relief of pruritus within 30 days prior to Screening. 18. Within in the past 12 months, have expressed suicidal ideation with some intent to act. 19. Have any social or medical condition (e.g. alcoholism, drug dependency, psychotic state) that, in the investigator's opinion, might interfere with the subject's ability to comply with the requirements of the protocol.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

|Overall Status||Active, not recruiting|
The disease, disorder, syndrome, illness, or injury that is being studied.
The investigator will determine whether more patients taking serlopitant 5 mg daily as compared to placebo can achieve a 3 point or greater reduction in itch severity as measured by numeric rating scale (NRS) score following two months of treatment. Secondary objectives include; 1. comparative weekly change in daily worst-itch NRS, 2. comparative weekly change in average daily NRS itch severity, 3. the proportion of patients who achieve at a least 30% or 50% reduction in NRS severity from baseline at the end of two months of treatment, 4. proportion of patients achieving 2 point and 4 point reductions in average daily itch severity following two months of treatment, 5. change in participant-reported outcomes of global assessment of change in itch and overall improvement as measured by static participant assessment of itch, participant global assessment of change in itch severity, and caregiver global assessment of change in itch severity, and. 6. assessment on the safety of Serlopitant in adolescents (≥13 y.o.) and adults with pruritus associated with epidermolysis bullosa (EB).
Placebo Comparator: Placebo Oral Tablet
We aim to recruit at least 20 patients who will undergo two months of dosing with placebo (inactive drug or sugar pill), followed by one month of wash-out. All patients will be offered the option of participating in a 12-month open label extension with serlopitant at 5 mg (taken by mouth) daily for continued safety monitoring.
Active Comparator: Serlopitant Tablet
We aim to recruit at least 20 patients who will undergo two months of Serlopitant dosing, followed by one month of wash-out. All patients will be offered the option of participating in a 12-month open label extension with serlopitant 5 mg (taken by mouth) daily for continued safety monitoring.
Drug: - Serlopitant Tablet
Serlopitant is a small molecule, highly selective NK1-R (neurokinin-1 receptor) antagonist. Two critical mediators of the urge to scratch are Substance P, or SP, and its receptor, NK1-R. SP is a naturally occurring peptide in the tachykinin neuropeptide family. Tachykinins have a broad range of functions in the nervous and immune systems. SP binding of NK1-R has been shown to be a key mediator of sensory nerve signaling, including the itch-scratch reflex and the vomiting reflex.
Drug: - Placebo Oral Tablet
The placebo is a tablet that looks like a drug but has no drug or other active ingredient in it.
