Study summary

The primary objective of CRAD001M2305 was to report the long-term effects of everolimus treatment on height, weight and sexual development (using Tanner Stages) in children and adolescents with Tuberous Sclerosis Complex (TSC)-associated with Subependymal Giant Cell Astrocytoma (SEGA). The study monitored the growth and development of pediatric patients with TSC-associated SEGA, previously enrolled in CRAD001M2301 (NCT00789828) until they reach Tanner Stage V, or until age 16 for females or 17 for males whichever occurred first.

Read the detailed description

CRAD001M2305 was a prospective, multi-center phase IIIb/IV study. This study investigated if the physical and sexual development of pediatric patients was affected by previous or ongoing treatment with everolimus. The study monitored the growth and development of pediatric patients with TSC-associated SEGA, previously enrolled in CRAD001M2301(NCT00789828) until they reached Tanner Stage V, or until age 16 for females or 17 for males whichever occurred first. Continued treatment with everolimus was at investigator discretion and was not required for participation in CRAD001M2305. Growth (height, weight), and sexual development (Tanner Stages, sex hormone levels, age at menarche, thelarche (females) and adrenarche (males)), and brain development (assessed by TAND Checklist, dates of brain MRI) of patients participating in this long-term follow-up study was followed at annual visits to the site until patients achieve Tanner Stage V or age 16 (females), age 17 (males) whichever occurred first. Adverse events, concomitant medication, appearance of menarche, were monitored and data collected every 3 months ("3-monthly"). Unless clinically indicated these 3-monthly visits were performed per telephone.

What researchers measure

Primary outcomes

  1. Number of Participants Who Achieved Tanner Stage V at or Before Age 16 (Females) or 17 (Males)

    Tanner Staging, also known as Sexual Maturity Rating (SMR), is an objective classification system that providers use to document and track the development and sequence of secondary sex characteristics of children during puberty. Tanner Stage included two components for boys (testis and pubic hair) and two components for girls (breast development and pubic hair). Tanner Stage V: Males and females: Terminal hair that extends beyond the inguinal crease onto the thigh. Female Breast Development Scale: Areolar mound recedes into single breast contour with areolar hyperpigmentation, papillae development, and nipple protrusion. Male External Genitalia Scale: \> 20 ml (or \> 4.5 cm long)

    Time frame: Annually, up to 14 years from the first visit in parent study CRAD001M2301 (including up to 9 years of follow-up in study CRAD001M2305)

  2. Number of Participants With Notably Low and Notably High Height and Body Mass Index (BMI) Standard Deviation Score (SDS)

    Height and body weight (with minimal clothing, without shoes) were measured annually. The height standard deviation score (SDS) and BMI SDS were calculated based on height/BMI data collected during the study and published reference height/BMI information (De Onis M, et al. Development of a WHO growth reference for school-aged children and adolescents. Bull World Health Organ. 2007 Sep;85(9):660-7). The number of participants with height and BMI SDS values lower than the 5th percentile (notably low) or higher than the 95th percentile (notably high) are reported. The baseline corresponds to the last available assessment on or before the start of everolimus in the parent study CRAD001M2301. The assessment is performed up to age of 12 years.

    Time frame: Baseline, annually up to Year 10 of treatment since the start of everolimus in parent study CRAD001M2301 (including a median of 5 years of exposure to everolimus in study CRAD001M2305)

  3. Endocrine Laboratory Values LH and FSH in Male Participants

    Luteinizing hormone (LH) is a glycoprotein hormone that is co-secreted along with follicle-stimulating hormone by the gonadotrophin cells in the adenohypophysis (anterior pituitary). Untreated LH deficiency results in infertility, and if it occurs before puberty, the patient fails to develop puberty and secondary sexual characteristics. Follicle-stimulating hormone (FSH) is a hormone produced by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) from the hypothalamus. FSH plays a role in sexual development and reproduction in both males and females.

    Time frame: Annually, starting at 10-year age until 16-year age (in both studies CRAD001M2301 and CRAD001M2305)

  4. Endocrine Laboratory Values LH and FSH in Female Participants

    Luteinizing hormone (LH) is a glycoprotein hormone that is co-secreted along with follicle-stimulating hormone by the gonadotrophin cells in the adenohypophysis (anterior pituitary). Untreated LH deficiency results in infertility, and if it occurs before puberty, the patient fails to develop puberty and secondary sexual characteristics. Follicle-stimulating hormone (FSH) is a hormone produced by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) from the hypothalamus. FSH plays a role in sexual development and reproduction in both males and females.

    Time frame: Annually, starting at 10-year age until 16-year age (in both studies CRAD001M2301 and CRAD001M2305)

  5. Endocrine Laboratory Values of Testosterone in Male Participants

    Testosterone is the primary male hormone responsible for regulating sex differentiation, producing male sex characteristics, spermatogenesis, and fertility.

    Time frame: Annually, starting at 10-year age until 16-year age (in both studies CRAD001M2301 and CRAD001M2305)

  6. Endocrine Laboratory Values of Estrogen in Female Participants

    Estrogen is a steroid hormone associated with the female reproductive organs and is responsible for developing female sexual characteristics.

    Time frame: Annually, starting at 10-year age until 16-year age (in both studies CRAD001M2301 and CRAD001M2305)

Secondary outcomes

  1. Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Number of participants with treatment emergent AEs (any AE regardless of seriousness), AEs led to study treatment discontinuation, SAEs and SAEs led to study treatment discontinuation.

    Time frame: From enrollment in study CRAD001M2305 until end of study, up to approximately 9 years.

  2. Participants Age at Menarche/Thelarche (Females) or Adrenarche (Males)

    Menarche is defined as the first menstrual period in a female adolescent. Menarche typically occurs between the ages of 10 and 16, with the average age of onset being 12.4 years. Thelarche is the beginning of adult breast development, marks the onset of puberty in the majority of women and occurs at a mean age of 10 years. Adrenarche refers to the time during puberty when the adrenal glands increase their production and secretion of adrenal androgens. Potential delayed puberty in girls is defined as failure to attain Tanner Stage II (for both breast development and pubic hair) by age 13, or absence of menarche by age 15 or within 5 years of attainment of Tanner Stage II. Potential delayed puberty in boys is defined as failure to attain Tanner Stage II (for both testis and pubic hair) by age 14.

    Time frame: Up to approximately 14.4 years from the first dose of everolimus in parent study CRAD001M2301 (including up to 9 years of follow-up in study CRAD001M2305)

  3. Participants Age at Tanner Stage II, III, IV, V

    Tanner Staging, also known as Sexual Maturity Rating (SMR), is an objective classification system that providers use to document and track the development and sequence of secondary sex characteristics of children during puberty. Pubic Hair Scale Stages: II-Downy hair III-Scant terminal hair IV-Terminal hair that fills the entire triangle overlying the pubic region V-Terminal hair that extends beyond the inguinal crease onto the thigh Female Breast Development Scale Stages: II-Breast bud palpable under the areola (1st pubertal sign in females) III-Breast tissue palpable outside areola; no areolar development IV-Areola elevated above the contour of the breast, forming a "double scoop" appearance V-Areolar mound recedes into single breast contour with areolar hyperpigmentation, papillae development, and nipple protrusion Male External Genitalia Scale Stages: II- 2.5 to 3.3 cm long, 1st pubertal sign in males III- 3.4 to 4.0 cm long IV- 4.1 to 4.5 cm long V- or \> 4.5 cm long

PrimaryEndocrine Laboratory Values LH and FSH in Female Participants

Luteinizing hormone (LH) is a glycoprotein hormone that is co-secreted along with follicle-stimulating hormone by the gonadotrophin cells in the adenohypophysis (anterior pituitary). Untreated LH deficiency results in infertility, and if it occurs before puberty, the patient fails to develop puberty and secondary sexual characteristics. Follicle-stimulating hormone (FSH) is a hormone produced by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) from the hypothalamus. FSH plays a role in sexual development and reproduction in both males and females.
