Androgen Therapy and Male Hypogonadism

Clinical research includes testosterone-based hormone replacement for male hypogonadism, with attention to transdermal delivery and comparative bioavailability in healthy participants.

  • Testosterone transdermal gel
  • Hormone replacement therapy
  • Bioequivalence

The sponsor’s interest in this area centers on androgen delivery systems and formulation comparison.

Female Reproductive Hormones

Trials cover progesterone, levonorgestrel, and etonogestrel products, reflecting a strong focus on contraceptive and reproductive endocrinology applications.

  • Progesterone vaginal insert
  • Levonorgestrel intrauterine system
  • Etonogestrel implant

These studies examine hormonal formulations used in family planning and cycle-related care.

Emergency Contraception and Selective Progesterone Modulation

Research also includes ulipristal tablets, indicating interest in emergency contraception and progesterone receptor modulation under both fed and fasting conditions.

  • Ulipristal tablets
  • Emergency contraceptive therapy
  • Oral hormonal formulations

This area highlights oral reproductive-health products evaluated for comparative absorption and formulation performance.

The sponsor funds studies involving 2-methoxyestradiol, a compound linked to estrogen-related biology and hormonal research in healthy female participants.

  • 2-Methoxyestradiol
  • Estrogen metabolism
  • Hormone-based therapeutics

These investigations broaden the company’s portfolio across sex hormone pharmacology and reproductive medicine.
