Study summary

The FLX-787-106 study will determine how well FLX-787-ODT works to reduce fasciculations in patients with Amyotrophic Lateral Sclerosis (ALS). The study will measure how often fasciculations occur, and monitor any side effects that might develop while taking the investigational product. Participants will be assessed before and after taking a single dose of FLX-787-ODT. Approximately 15 people will take part in this study at one center in the United States. Participants will be in the study for a single clinic visit and receive a telephone call 7 days later to monitor for side effects.

Inclusion criteria

  • Documented diagnosis of ALS diagnosis of less than 3 years.
  • Expected survival > 6 months
  • Frequent fasciculations noted during clinical examination of any single muscle (>6 visible fasciculations per minute) observed in Part I
  • Normal oral cavity exam at screening
  • Proficient in English
  • Male subjects will either be surgically sterile or agree to use a medically acceptable method of during sexual contact with females of , and will refrain from sperm donation for 45 days following the study
  • Male subjects will either be surgically sterile or agree to use a medically acceptable method of contraception during sexual contact with females of childbearing potential, and will refrain from sperm donation for 45 days following the study

Exclusion criteria

Exclusion Criteria:

  • Presence of or unstable condition that would result in an increased risk of study participation or difficulty in interpretation of the study results
  • Tremor or other movement disorder that would interfere with recording
  • Inability to lie flat
  • Presence of major gastrointestinal disorders, such as inflammatory bowel disease, diverticulitis, active peptic ulcer disease, or significant gastroesophageal reflux disease (i.e., not well-controlled on antacids or proton pump inhibitors), or oral or esophageal lesions/ulcers
  • Presence of laryngospasm or significant swallowing problems
  • Presence of percutaneous endoscopic gastrostomy, esophagogastroduodenoscopy, or G-tube
  • Inability to tolerate a spicy sensation in the mouth or stomach
  • Actively using illicit drugs or history of chronic substance abuse within the past year prior to screening, including abuse of alcohol
  • Participated in a clinical study (except natural history studies without administration of an product) within 30 days prior to screening
  • Pregnant, breastfeeding, or planning to become pregnant
  • Blood pressure of ≥160 mmHg systolic and/or ≥100 mmHg diastolic
  • Clinically significant abnormalities in laboratory findings (including screening complete electrolyte panel, complete blood count, liver function tests).
Terms in these criteria, in plain language(4)

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.

Contraception

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Clinically significant

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
