Details and patient eligibility

About

The comparator drug (Zoladex 3.6 mg) is approved for use as a thinning agent for the endometrium prior to endometrial ablation. The dosing recommendation is one or two depots with each depot given four weeks apart. When two depots are administered, surgery should be performed within two to four weeks following administration of the second depot.

Full description

The primary objective of the study is to demonstrate non-inferiority of a generic formulation of goserelin 3.6 mg as compared to Zoladex ® 3.6 mg on endometrial thinning prior to surgery. The study is an open label, multicenter, prospective, parallel group randomized study.

Blind for Sponsor, ultrasound assessment, testing labs and statistician, the study will be performed in premenopausal women with dysfunctional uterine bleeding (DUB) eligible for endometrial ablation. Patients will be randomized in a 1 to 1 ratio to receive either the Peptigroupe test product (Pepti 3.6 mg) or Zoladex® 3.6 mg for a treatment of 8 weeks (two injections).

Ultrasonic measurement of endometrial thickness will be performed on screening and on days 0 (pre-injection), 28 (pre-injection) and 42 (pre surgical procedure).

The pharmacodynamics profile will be tabulated at the end of the study on the basis of the following data:

Estradiol
LH and FSH as additional information on hormone response

Goserelin safety profile will be assessed throughout the study on the basis of the following assessments:

Treatment-emergent AEs
Physical examinations
Vital signs
12-Lead ECG
Laboratory parameters (i.e., biochemistry, haematology, and urinalysis)

Appropriate sized uterus with no anatomic pathologies 7. Patient is not pregnant and does not wish to become pregnant in the future 8. Patient is willing to use a non-hormonal contraception method during the study, nor an intra-uterine device 9.

Exclusion criteria

Be pregnant or have desire to conceive
Have abnormal endometrial cytology as confirmed by histology
Have active endometritis
Have active pelvic inflammatory disease
Have active sexually transmitted disease (STD), at the time of ablation. Note: Treatment of STD documented in the chart serves as sufficient evidence of infection resolution. Patient may be considered for study enrollment.
Presence of bacteremia, sepsis, or other active systemic infection
Have active infection of the genitals, vagina, cervix, uterus or urinary tract at the time of inclusion
Known/suspected gynecological malignancy within the past 5 years
Known clotting defects or bleeding disorders

Currently on medications that could thin the myometrial muscle, such as long-term steroid use (except inhaler or nasal therapy for asthma)
Currently on anticoagulants
Have a known hypersensitivity to gonadotropin releasing hormone (GnRH), GnRH agonists, any LHRH agonists (e.g., leuprolide (Lupron®), goserelin ( Zoladex®) etc.) or to the PLGA polymers contained in the study formulation
Have a severe liver disease (e.g., cirrhosis, chronic active hepatitis or chronic persistent hepatitis) or has persistent ALT, AST ˃ 2 X ULN, serum creatinine ˃ 2 X ULN, serum bilirubin ˃ 2 X ULN
Have received an investigational drug or participated in a clinical trial within the last 30 days
Have clinically serious and/or unstable concurrent infection, medical illnesses or conditions that are uncontrolled or whose control, in the opinion of the Investigator, may be jeopardized by participation in this study or by the complications of this therapy
Patients with BMI ˂ 18
Anticoagulated patients with INR ≥ 2
Patients with a history of QT prolongation, congenital long QT syndrome, electrolyte abnormalities, CHF, or concurrent administration with QT prolonging drugs or QTc ˃450 msec.
