Inclusion criteria

  • The subject must complete all Study NLS-1021 study requirements and assessments up to Visit 6;
  • The subject is able, in the opinion of the Investigator, to receive NLS-2 for the 24-week Treatment Phase of this study;
  • Biological females of must agree to use a medically acceptable double-barrier method of for at least 30 days prior to Day 1 and until completion of the study;
  • The subject is able to comply with the open-labelled extension design schedule and other study requirements;
  • The subject provides written for the open-label extension study.

Exclusion criteria

  • The subject meets any Exclusion Criteria for Study NLS-1021 at Visit 6 of that study;
  • The subject receives any drug (other than the COVID-19 vaccine) that is not NLS-2.
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.

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.

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.

Informed consent

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.

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.
