Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Key exclusion criteria
For Healthy Volunteers and Post-Herpetic Neuralgia Patients

1. Presence or history of carcinoma, hepatic, renal, neurological, pulmonary (except for childhood asthma), endocrine, hematologic, cardiovascular, or genitourinary disease that, in the opinion of the Investigator, may affect the evaluation of the IP or place the participant at undue risk (except for conditions that are stable on medications).
2. Presence of any underlying physical or psychiatric condition (except for conditions that are stable on medications) that, in the opinion of the Investigator, would undermine participant compliance to protocol requirements.
3. Presence or history of gastrointestinal disease (e.g., peptic ulcer, gastritis, gastric cramp, gastroesophageal reflex disease, Crohn's disease) or history of gastrointestinal surgery (except simple appendectomy or herniorrhaphy) that may affect assessment of safety and PK characteristics of the IP.
4. Presence or history of central nervous system disease that may affect assessment of safety and PK characteristics of the IP.
5. Presence of herniated disc (inter-vertebral, cervical or both) or history of related disease that, in the opinion of the Investigator, may affect assessment of safety and PK characteristics of the IP.
6. History of hypersensitivity to iN1011-N17 or to any of its components.
7. History of allergy or sensitivity to sulfonamides, hay fever, asthma, eczema, food allergies and/or allergies to other medications.

24. Other severe pain or the presence of other skin diseases or pain at the site of the rash at Screening or randomization unrelated to PHN, that may confound the assessment of PHN.
