Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Chronic tension-type headache (CTTH) is an underestimated disabling condition that affects a large number of patients. The treatment options for both episodic tension-type headaches, but especially CTTH are few. Poor long-term effects of existing treatment for CTTH (Sarotex, SSRIs, physiotherapy) are reported. Patients with CTTH also have a high risk of developing drug overdose headache (MOH). Non-drug treatments with physiotherapy or alternative medicine also show poor long-term effects. Literature reviews show that there is surprisingly little research on CTTH. Some small clinical trials report a good effect of treatment with botulinum toxin A, but larger controlled trials are needed to confirm or deny this.

The investigators will study effect of treatment with botulinum toxin A in CTTH in BACT study, and will include participants with both frequent and chronic TTH with 10 or more headache days per month.

If BACT outcomes are positive, this will open a possibility for a new treatment for TTH patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

BACT studies the efficacy of treatment with botulinum toxin with a follwthestuture injection regime in frequent and chronic tension type headache (TTH). This is be a randomized, placebo-controlled, triple blind, cross-over trial. The primary efficacy variable is the difference in monthly headache days in the active period versus the placebo period. In this study, injections will follow a slightly modified FollowTheSutures injection protocol. Study duration is 36 weeks long. The target population is male and female patients 18 to 75 years of age with TTH, with 10 or more headache days per month.

RANDOMIZED

Intervention Model

CROSSOVER

In this study, injections will follow a slightly modified FollowTheSutures injection protocol.

Study duration is 36 weeks long. A 4 weeks screening/baseline period with a daily electronic headache diary (eDiary) follows inclusion and informed consent. After completing the 4-week screening/baseline period, participants will be re-screened and eligible participants will enter the randomized phase of the study consisting of two treatment periods. The treatment periods is either injections with verum (onabotulinum toxin suspended in saline (Botox® and NaCl 0,9% Braun) or placebo (only NaCl 0,9% Braun). The participants are randomized to the order with which they enter the two periods, and a quadruple-blinding regime is implemented. Each treatment period lasts 12 weeks, separated by a 4 week washout period. Participants continue to keep a daily eDiary and register adverse events in the entire randomized period.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Aged 18 to 75 years
* Frequent or chronical tension type headache according to the ICHD-3 (2.2.3) criteria with 10 or more headache days per month
* Headache history of minimum one year.
* Previously unsatisfactory treatment effect, bothersome side-effects to or contra-indications to at least one TTH prophylactic drug.
* Subject agrees to maintain current preventive headache medication regimens (no change in type, frequency, or dose) during the whole study period.
* In case of women of childbearing potential (WOCBP) they have to be using highly effective contraception (for more details below).
* Signed informed consent.

Exclusion Criteria

* Patients with migraine with more than 1 migraine day per month.
* Patients with other forms of primary or secondary headaches; including medication overuse headache (MOH).
* Change in type, dosage or dose frequency of preventive headache medication \< 1 months prior to inclusion.
* Previous exposure at any time to any botulinum toxin serotype.
* Pregnancy, breastfeeding or planned pregnancy.
* Patients with diseases that are contraindications for use of BoNT-A (Myasthenia gravis, Eaton-Lambert syndrome, amyotrophic lateral sclerosis, other diseases interfering with neuromuscular function) or allergy to BoNT-A, or treatment with drugs affecting the neuromuscular junction;
* Active infection at the sites of injection
* Subject has been diagnosed with any major infectious processes such as osteomyelitis, or primary or secondary malignancies involving the face that have been active or required treatment in the past 6 months.
* Any psychiatric disorder that may affect ability to comply with study procedures in the opinion of study investigator.
* Other severe chronical pain conditions.
* Abuse of alcohol or illicit drugs.
* Participating in another trial that might affect the current study.

Contraception for women of childbearing potential (WOCBP) Such methods will include combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal or transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable or implantable); intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomised partner; sexual abstinence. This group of patients should not be using other drugs that might interact and reduce the efficacy of the used anticonceptive drug. WOCBP is defined as fertile women, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods, include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause.

Ability to understand study procedures and to comply with them for the entire length of the study. WOCBP will have to agree to take a pregnancy test before the injection with the study drug.
