Study summary

The study will evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) responses of FMXIN002, an intranasal epinephrine powder, compared with the EpiPen® intramuscular autoinjector, after single and double doses, in healthy adults with a history of allergic rhinitis.

Read the detailed description

Fifty participants will receive single and repeat doses of both treatments under normal and nasal congestion conditions induced by nasal allergen challenge. The study will also assess the effect of repeat nasal dosing in the same versus opposite nostrils. PK parameters and hemodynamic responses will be measured, and safety and tolerability will be evaluated.

Inclusion criteria

  1. Non-smoking, male and female participants, from 18 to 55 years of age.
  2. Documented positive skin allergy test at screening.
  3. History of hay fever, seasonal allergies, or allergic rhinitis during the last year.
  4. ≥18 and \< =30 kg/m2.
  5. Females may be of childbearing or non-:

    • Childbearing potential:

      o Physically capable of becoming pregnant, must be willing to use acceptable effective methods of .

    • Non-childbearing potential:

      • Surgically sterile (i.e., both ovaries removed, uterus removed, or bilateral tubal ligation); and/or
      • (no menstrual period for at least 12 consecutive months without any other medical cause and a FSH value consistent with being postmenopausal).
  6. Able to tolerate venipuncture.
  7. Be informed of the nature of the study and give written consent prior to any study procedure.
  8. Willing and able to remain in the clinic for the entire duration of the confinement period.
  9. Have good intravenous access on both arms and hands. -

Exclusion criteria

Exclusion Criteria:

  • History of neurologic, hematologic, endocrine, oncologic, pulmonary, immunologic, genitourinary, psychiatric, or cardiovascular disease or any other condition which, in the opinion of the Investigator, would jeopardize the safety of the participant or impact the validity of the study results.
  • Have clinically significant findings at screening.
  • Females who:

    • Have discontinued or changed the use of implanted, intrauterine, intravaginal, or injected hormonal within 6 months prior to the first drug administration;
    • Have discontinued or changed the use of oral or patch hormonal contraceptives within one (1) month prior to the first drug administration;
    • Are pregnant (serum β-hCG consistent with pregnancy); or
    • Are breast-feeding.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
