排除标准
- •Patients who meet any of the following criteria will be excluded from participating in the study;
- •be currently receiving any of the listed prohibited medications or have received within 30 days prior to the Screening Visit (Visit 1) or is anticipated to receive after the start of the trial (i.e. on or after Visit 1) any new prescription systemic or topical medication for their post herpetic neuralgia, patients may be enrolled if stable on therapy for their post herpetic neuralgia as specified in the list of permitted medications;
- •have received an investigational drug within 30 days or 10 half-lives of the drug, whichever is longer, prior to the Screening Visit (Visit 1) or have previously received EMA401; known to be allergic to EMA401 or any of the excipients or who have a history of an allergic reaction to previous medication that required management by a health care professional;
- •have a clinically significant history of systemic allergic disease (e.g., urticaria, atopic dermatitis);
- •have a blood pressure, after resting for at least 5 minutes, outside a systolic blood pressure range of 100-150 mmHg or a diastolic blood pressure outside a range of 50-90 mmHg on two consecutive measurements (at least 10 minutes apart and completed within 20 minutes of the initial measurement);
- •have a pulse rate, after sitting for at least 5 minutes, greater than 100 beats per minute or lower than 50 beats per minute, or 45 beats per minute if on beta blockers, on two consecutive measurements (at least 10 minutes apart and completed within 20 minutes of the initial measurement);

- •other than pain as a result of postherpetic neuralgia, have had a clinically significant illness or operative procedure within 4 weeks of the Screening Visit (Visit 1) (e.g. influenza, myocardial infarction);
- •have undergone neurolytic or neurosurgical therapy for postherpetic neuralgia;
- •have other moderate to severe pain condition that may confound the self-evaluation of pain due to postherpetic neuralgia;
- •have skin conditions in the affected area that in the investigator's opinion could alter sensation;
- •have active herpes zoster upon physical examination at Screening (Visit 1) or during the study;
