Beskrivelse
Inclusion Criteria:
- Participant is capable of providing signed informed consent.
- Participant must be between 18 to 80 years of age (inclusive), at the time of signing the informed consent.
- Confirmed diagnosis of classical or idiopathic TN according to the criteria of the International Classification of Headache Disorders-3rd edition (ICHD-3, 2018).
- The diagnosis of TN established at least 6 months prior to Screening.
- Participant has purely unilateral pain attacks limited primarily to the maxillary (V2) and/or mandibular (V3) division of the trigeminal nerve.
- Participant has failed at least 1 standard of care anti-epileptic agent (e.g., carbamazepine, oxcarbazepine, pregabalin, gabapentin, phenytoin, lamotrigine). Failure to a prior anti-epileptic medication is defined as insufficient pain relief despite use of a therapeutic dose for an adequate duration of time or being unsuitable due to contraindications or intolerance to side effects.
- Participant is on stable dosage of any TN anti-epileptic agent(s) for a minimum of 6 weeks prior to Screening.
Exclusion Criteria:
- Participant has bilateral TN pain attacks.
- Participants with secondary TN, defined by ICHD-3 as TN caused by an underlying disease (e.g., tumor in the cerebellopontine angle, arteriovenous malformation, or multiple sclerosis).
- Participants with facial pain not meeting the ICHD-3 diagnostic criteria for either classical or idiopathic TN, including: trigeminal autonomic cephalalgias, cluster headache, hemicrania continua, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA).
- Participants who had no change in pain after taking sodium channel blockers despite the use of a therapeutic dose for an adequate duration of time.

Eksperimentel: Participants receiving RP-008
Participants will receive a single dose of RP-008 on Day 1 at varying dose levels according to the dose escalation study design.
In addition, varenicline tartrate and oral corticosteroid (equivalent to prednisone or prednisolone) will be administered during the pre- and post-treatment follow-up periods.
|
RP-008 will be administered as a single percutaneous injection to the trigeminal ganglion.
Andre navne:
Varenicline tartrate will be administered as a daily oral tablet.
