About

The aim of this study is to establish with measures of clinical parameters by Magnetic Resonance Imaging (MRI) (e.g. crossing of the muscle fascias, length of run, injection depth, volume injected) performance of 2 configurations of the needle-free injector when used for intramuscular injection on bare skin or through clothing.

Full description

The development of needle-free injection devices has been motivated by a need for safer and more user-friendly injection devices that can prevent needle-stick injuries and contamination as well as improve patient comfort and treatment. As a growing number of drugs need to be injected or self-injected, needle-free devices are an attractive alternative to the conventional needle, especially in situation of emergency.

A medical emergency requires quick action to ward off a risk of imminent death and long-term sequelae, or to manage a situation of stress or crisis. Study's sponsor has developed an innovative, needle-free, prefilled, single use, disposable injector called ZENEO®. Unlike other needle-free injection devices, ZENEO® does not resemble a syringe in order to make injections with the device as natural and user friendly

The prefilled, single use, combined system of ZENEO® makes it ready to use for any type of drug or vaccine that needs to be injected into the skin (intradermal), under the skin (subcutaneous) or into the muscle (intramuscular).

According to regulatory requirements for market-authorization submission, proof of performance of ZENEO® injector for intramuscular (i.m.) injection must be established.

For each drug development as combination with the ZENEO® injector, clinical investigations will be conducted to study the relative bioavailability of the medicinal product when injected either with ZENEO® or with a conventional syringe.

Performance profile of ZENEO® injector for i.m. injection on the thigh with a target volume of 0.625 milliliter (mL) of an aqueous solution have been calculated and must be verified by clinical data in order to demonstrate successful delivery of the intended medication(s) to the target tissues, achieving therapeutic bioavailability, or reaching another appropriate endpoint in humans.

This is the reason why this clinical study CJTMRIZ2101 will be conducted.

After a screening period of a maximum of 21 days, eligible subjects will be randomized in a 1:1:1:1 allocation ratio and will receive 2 intramuscular injections on the thigh with ZENEO® pre-filled with 0.64 mL of physiological serum, at 2 treatments periods - Period 1 (P1) and Period 2 (P2) - separated by a wash-out period of at least 7 days. Each injection will be spaced of no more than 5 minutes. Within 10 minutes after the first injection and no more than 5 minutes after the second injection, subjects will be settled for the MRI sequences acquisition (about 20 minutes) so that the MRI acquisition should end no more than 30 minutes (+/- 5 minutes) after the first injection.

A follow-up visit (phone contact) will systematically be performed two days after Day 1 of P1 and Day 1 of P2, in order to confirm there is no safety concern on the injection site and to confirm the subject's well-being. If a subject indicates a pain score >5 or any significant anomaly an on-site follow-up visit will be organized within 7 days after each follow-up phone call.

A total of 50 healthy volunteers will be enrolled in this investigation with at least 30% of males and 30% of females are expected.

Inclusion criteria

  1. Male or female volunteers aged between 18 and 59 years (inclusive) at the Screening Visit.

  2. Female subjects of childbearing potential (i.e., fertile, following menarche and until becoming post-menopausal unless permanently sterile: neither post-menopausal nor surgically sterile) who are sexually active with a non-sterile male partner must be willing to use one of the following effective contraceptive methods throughout the study and for 30 days after the last study intervention:

    1. Combined estrogen and progestogen-containing or progestogen-only hormonal contraception associated with inhibition of ovulation, started at least 4 weeks prior to the first study intervention;
    2. Intrauterine device placed at least 4 weeks prior to the first study intervention, and condom for the male partner;
    3. Simultaneous use of a diaphragm or cervical cap with intravaginally applied spermicide and for the male partner a male condom;
    4. Sterile male partner (i.e. vasectomized since at least 6 months prior to the first study intervention);
    5. Sexual abstinence (when in line with the preferred and usual subject lifestyle). Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) is not acceptable.
  3. Female subjects of non-childbearing potential must be:

    1. Post-menopausal female (absence of menses for 12 months prior to the first [if applicable] study intervention); or
    2. Surgically sterile female (documented hysterectomy, or bilateral oophorectomy or bilateral tubal ligation/occlusion) or bilateral tubal ligation at least 6 months prior to the first [if applicable] study intervention).
  4. Subject with BMI between ≥ 16.0 and < 35.0 kg/m² at the Screening Visit.

  5. Injection sites must be clear of tattoos, scars and moles.

  6. Affiliated to or covered by the French social security system.

  7. Signed written consent given for participation in the study.

Exclusion criteria

  1. Known Contra-Indication to i.m. injection.
  2. Treatment with platelet inhibiting drugs within one week before inclusion.
  3. Treatment with anticoagulant within four weeks before inclusion.
  4. Any Contra-indication to MRI (ex: metallic intra-corporeal devices, claustrophobia, tremor or abnormal movements whatever the origin is).
  5. A major illness during the 3 months before the screening period, that may interfere with the evaluation, as judged by the investigator
  6. Any history or evidence of any clinically significant cardiovascular, gastrointestinal, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary neurologic, dermatologic, psychiatric, renal, and/or other major disease or malignancy, as judged by the Investigator.
  7. Any clinically significant abnormality following the Investigator's review of the physical examination, ECG and clinical study protocol-defined clinical laboratory tests at screening or admission to the clinical unit.
