Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43874   clinical trials with a EudraCT protocol, of which   7294   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.3Principal inclusion criteria
    1. Willing and able to provide written informed consent prior to any study-related procedures.
    2. Willing and able to comply with the study procedures as specified in the protocol and comply with the study treatment administration.
    3. Subjects ≥18 years of age at the time of Screening, who fall into 1 of the following 3 groups are eligible to participate in the study.
    • Medically naïve group (Group 1): Those who have not been previously treated with acromegaly medications (including LA-SRLs) who at Screening have IGF 1 ≥1.3×ULN (the lower limit for eligibility is mean IGF-1 of 1.25×ULN when rounded to 2 decimal places) confirmed by the central laboratory test at S1. Group 1 subjects must have had at least 1 pituitary surgery 3
    months or more prior to Screening.
    • Previously Treated group (no treatment within previous 4 months) (Group 2): Subjects who have last been treated with acromegaly medications at least 4 months prior to Screening and who have IGF 1 ≥1.3×ULN (the lower limit for
    eligibility is mean IGF-1 of 1.25 when rounded to 2 decimal places) confirmed by the central laboratory test at S1.
    • Washout group (Group 3): Subjects at Screening who are receiving stable treatment (no change in dose for 3 months prior to Screening) with octreotide or lanreotide monotherapy, who have IGF-1 ≤1.0×ULN (the upper limit for eligibility is mean IGF-1 of 1.04 when rounded to 2 decimal places) at Screening Visit 1 and are willing to washout of their medication during the Screening Period. Any form of pretrial octreotide or lanreotide monotherapy (long- or short-acting [SC, IM, or oral]) can be washed out
    and will determine the duration of the Screening Period. After informed consent is provided, the subject should not receive further pretrial acromegaly medication. IGF-1 must rise at least 30% from the first Screening Visit to the last Screening Visit and to ≥1.1×ULN (the lower limit for eligibility is mean IGF-1 of 1.05 when rounded to 2 decimal places) confirmed by the central laboratory test at S2 or S3, if needed) to qualify for enrollment.
    4. Previous diagnosis of acromegaly confirmed by the Investigator and approved by the Medical Monitor. This requires evaluable documentation of a pituitary adenoma.
    5. If currently using thyroid hormone therapy, the subject should be adequately treated based on clinical status and free thyroxine concentration measured during Screening and on a stable dose of thyroid hormone for at least 8 weeks prior to Screening.
    6. Females who engage in heterosexual intercourse must be of non childbearing potential, defined as either surgically sterile (i.e., hysterectomy, bilateral salpingectomy, or bilateral oophorectomy), OR be postmenopausal with at least 1 year of amenorrhea, OR must agree to use either a highly effective or a clinically acceptable method of contraception from the beginning of Screening until at least 30 days after the last dose of study drug.
    7. If the subject is male, the subject should agree to use a condom when sexually active with a female partner of childbearing potential from Screening until at least 30 days after the last dose of study drug (or be surgically sterile [i.e., vasectomy with documentation]; or remain abstinent [when this is in line with the preferred and usual lifestyle]. Male subjects should also agree to not donate sperm for the duration of the study and until at least 30 days after the last dose of study drug.
    E.4Principal exclusion criteria
    1. History of ineffectiveness or significant intolerance of octreotide or lanreotide treatment, as determined by the Investigator.
    2. History of pituitary radiation therapy within 3 years of Screening.
    3. Subjects with adrenal insufficiency, diabetes insipidus, or central hypogonadism who are not receiving adequate hormone replacement therapy at the time of Screening, as determined by the Investigator.
    4. High risk pituitary tumor pattern as defined by:
    • Compression of the optic chiasm or invasion of adjacent brain structures (other than sphenoid sinus or cavernous sinus)
    • History of tumor growth within 1 year after surgery or radiation (unless it occurred during a period of medical therapy interruption)
    • Anticipated requirement for neurosurgical intervention or radiation therapy within the time course of the study.
    • Pituitary carcinoma currently or at any time in the past.
    5. History of major surgery/surgical therapy for any cause within 4 weeks prior to Screening.
    6. Diabetes mellitus treated with insulin for less than 6 weeks prior to the study entry, or with change in total daily insulin dose by >15% within 6 weeks prior to Screening.

    11. Use of the following medications as outlined:
    Any history of acromegaly medication use (G1 only)
    • Lanreotide depot or octreotide LAR (within 16 weeks before Screening) (G2 only)
    • Pasireotide LAR (within 24 weeks prior to Screening)
    • Pegvisomant (within 16 weeks before Screening)
