Female and male patients of child-producing potential must agree to avoid becoming pregnant or impregnating a partner, respectively, use double-barrier contraceptive measures, oral contraception, or avoidance of intercourse, during the study*, and until at least 120 for 90 days after the last dose of derazantinib. *From the day of first study medication, or for oral contraception from 14 days before first study medication. Male patients are considered not to be of child-producing potential if they have azoospermia (whether due to vasectomy or an underlying medical condition). Female patients are considered not to be of child-producing potential if they are:
• postmenopausal* , or
• have had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy or bilateral tubal ligation/occlusion, at least 6 weeks prior to screening, or
• have a congenital or acquired condition that prevents childbearing. Male or female patients of child-producing potential must agree to comply with one of the following until at least 120 days after the last dose of derazantinib: 1. Abstinence from heterosexual activity** 2. Using (or having their partner use) an acceptable method of contraception during heterosexual activity. Acceptable methods of contraception are***:
• any ONE of:
•an intrauterine device (IUD)
•vasectomy of a female patient's male partner
•a contraceptive rod implanted into the skin.
• any TWO in combination of:
•diaphragm with spermicide (cannot be used in conjunction with cervical cap/spermicide)
•cervical cap with spermicide (nulliparous women only)
•contraceptive sponge (nulliparous women only)
•male condom or female condom (cannot be used together)
•hormonal contraceptive (oral contraceptive pill [estrogen/progestin pill or progestin-only pill], contraceptive skin patch, vaginal contraceptive ring, or subcutaneous contraceptive injection) *Postmenopausal is defined as at least 12 months with no menses without an alternative medical cause; in women < 45 years of age a high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post -menopausal state in women not using hormonal contraception or hormonal replacement therapy. In the absence of 12 months of amenorrhea, a single FSH measurement is not sufficient.
• Abstinence (relative to heterosexual activity) can be used as the sole method of contraception if it is consistently employed as the subject's preferred and usual lifestyle and if considered acceptable by local regulatory agencies and ERCs/IRBs. Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, post-ovulation methods, etc.) and withdrawal are not acceptable methods of contraception.
• If a contraceptive method listed above is restricted by local regulations/guidelines, then it does not qualify as an acceptable method of contraception for subjects participating at sites in this country/region. 1.
