Outcome Measures

Primary Outcomes (1)

  • Days with tension-type headache (TTH) during the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

    Days with tension-type headache (TTH) during the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

    During the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

Secondary Outcomes (6)

  • Total headache index AUC (area under the curve) during the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

    during the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

  • Headache severity (VAS 0-10) and duration (hours per day) during the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

    during the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

  • Acute analgesic consumption: number of days and dosage

    during the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

  • Treatment effectiveness criterion: reduction in headache days by ≥50% during the third 4-week intervention period compared to the screening period

    during the third 4-week intervention period

  • Safety assessment and tolerability evaluation

    During the 12-week intervention period (reported in 4-week intervals: Weeks 0-4, 5-8, and 9-12)

  • +1 more secondary outcomes

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female subjects aged 18-65 years
  • Meeting the diagnostic criteria for tension-type headache (TTH) according to ICHD-3; with ≥6 but \<15 attack days per month in the past 3 months and MIDAS score \>21; onset of TTH before age 50, with a history exceeding 1 year
  • Informed consent obtained from the patient

You may not qualify if:

  • History of allergy to Desvenlafaxine, or use of Desvenlafaxine within 4 weeks prior to the start of the treatment period; currently taking or requiring concomitant administration of drugs contraindicated in the package insert, such as monoamine oxidase inhibitors (MAOIs);
  • Diagnosable with chronic tension-type headache or medication overuse headache;
  • Comorbid with other types of headaches, such as trigeminal autonomic cephalalgias, migraine attacks \>1 time/month within 3 months, or secondary headaches (e.g., those caused by intracranial infections, craniocerebral trauma, cerebrovascular diseases);
  • Severe psychiatric disorders such as schizophrenia, moderate to severe anxiety-depression (Hamilton scale ≥12 points); poorly controlled epilepsy, cognitive impairments, and other chronic pain conditions; serious organic diseases that pose significant health risks, including uncontrolled hypertension, cardiac disease, hepatic dysfunction, renal insufficiency, infections; any medical condition or prior surgery likely to affect the absorption, metabolism, or excretion of the study drug;
  • Concomitant use of venlafaxine analogues such as serotonin-norepinephrine reuptake inhibitors (SNRIs); unstable use of other preventive medications for TTH, including amitriptyline, mirtazapine (≤3 months); discontinuation of currently reported effective prophylactic drugs or overused analgesics for ≥3 months may allow re-enrollment;
  • Alcohol dependence or substance abuse;
  • Inability to comprehend the study protocol due to low education level, impaired verbal/language function, visual or auditory deficits; failure to accurately complete research materials like headache diaries or cooperate with scale assessments;
  • Women who are planning pregnancy, pregnant, breastfeeding, or not using contraception;
  • Participation in other interventional clinical studies that may influence outcome evaluations.
