Inclusion Criteria:
- Male or female subjects 18-60 years of age
- Planned to receive a deceased or living donor kidney transplant
- Sensitized patients: Positive sum DSA <1000, and/or PRA>0%.
- Subjects must be capable of understanding the purpose and risks of the study and must
sign a statement of informed consent.
- Female subjects must be post-menopausal, surgically sterilized, or she and/or sexual
partner must be willing to use an acceptable method of birth control with a <1%
failure rate as stated in the product label from time of study consent, during study
participation, and for 16 weeks after the last dose of the study agent (i.e.,
contraceptive subdermal implant of levonorgestrel or etonogestrel, intrauterine device
or intrauterine system, combined estrogen and progestogen oral contraceptive,
Injectable progestogen, contraceptive vaginal ring, percutaneous contraceptive
patches, or abstinence) for the duration of the study. Male partner sterilization with
documentation of azoospermia prior to the female subject's entry into the study, and
this male is the sole partner for that subject. The documentation of male sterility
can come from the site personnel's: review of subject's medical records, medical
examination and/or semen analysis, or medical history interview provided by her or her
partner. Note: Mycophenolate mofetil (MMF) affects the metabolism of oral
contraceptives and may reduce their effectiveness. As such, women receiving MMF who
are using oral contraceptives for birth control should employ an additional method
(e.g., barrier method). Mycophenolate can cause fetal harm when administered to a
pregnant female. Use of mycophenolate during pregnancy is associated with an increased
risk of first trimester pregnancy loss and an increased risk of congenital
malformations. Mycophenolate affects the metabolism of oral contraceptives and may
reduce their effectiveness. As such, women receiving MMF who are using oral
contraceptives for birth control should employ an additional method (e.g., barrier
method) resulting in two reliable forms of contraception being used simultaneously
before starting study treatments, during therapy, and for 6 weeks after stopping
therapy; unless abstinence is the chosen method of contraception
- Female patients of childbearing potential must have a negative serum pregnancy test
within 48 hours of transplant. Must be willing to use contraceptives from the time of
study consent, during study participation, and for 16 weeks after the last dose of
study agent. For sexually active men, condoms should be used during, and for at least
90 days after cessation of mycophenolate treatment. No sperm donation should be made
during this period of time. For female partners of male subjects, it is recommended to
use highly effective contraception during treatment and for 90 days after the last
dose of mycophenolate
- No blood donation should be made by the study subjects during mycophenolate treatment
and for at least 6 weeks after stopping mycophenolate treatment
- If stricter female or male contraception requirements are specified in the
country-specific label for any study related therapies, they must be followed.
- Male subjects must agree to use an acceptable method for contraception for the
duration of the study.
Female patients of childbearing potential must have a negative serum pregnancy test within
48 hours of transplant. Must be willing to use contraceptives from the time of study
consent, during study participation, and for 16 weeks after the last dose of study agent.
Reproductive Status: Definition of Women of Child-Bearing Potential (WOCBP). WOCBP
comprises women who have experienced menarche and who have not undergone successful
surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy)
or who are not post-menopausal (see definition below).
Post-menopause is defined as:
- Women who have had amenorrhea for greater than or equal to 12 consecutive months
(without another cause) and who have a documented serum follicle-stimulating hormone
(FSH) level > 35 mIU/mL.
- Women who have irregular menstrual periods and a documented serum FSH level > 35
mIU/mL.
- Women who are taking hormone replacement therapy (HRT).
The following women are WOCBP:
- Women using the following methods to prevent pregnancy: Oral contraceptives, other
hormonal contraceptives (vaginal products, skin patches, or implanted or injectable
products), or mechanical products such as intrauterine devices or barrier methods
(diaphragm, condoms, spermicides).
- Women who are practicing abstinence from intercourse from 2 weeks prior to
administration of the 1st dose of study agent until 16 weeks after the last dose of
study agent (Sexual inactivity by abstinence must be consistent with the preferred and
usual lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation,
symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of
contraception)
- Women who have a partner who is sterile (e.g., due to vasectomy). WOCBP must be using
an acceptable method of contraception to avoid pregnancy from the time of consent with
<1% failure rate as stated in the product label throughout study participation, and
for 16 weeks after the last dose of study drug in such a manner that the risk of
pregnancy is minimized. Acceptable methods of contraception include: complete
abstinence, any form of intra-uterine devices (without hormones), tubal sterilization
or your partner has had a vasectomy.
Other acceptable forms of birth control include choosing one hormonal and one barrier
method or double-barrier methods. Barrier methods include Essure®, male or female condom,
diaphragm with spermicide, shield, cap with spermicide, contraceptive sponge, and
spermicidals. Hormonal methods include oral contraceptive pills, transdermal patches,
vaginal rings, progesterone-only, and injections. Periodic abstinence (for example,
calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not
acceptable methods of contraception.
- These allowed methods of contraception are only effective when used consistently,
correctly and in accordance with the product label. The investigator is responsible
for ensuring subjects understand how to properly use these methods of contraception.
- WOCBP must have a negative serum or urine pregnancy test result (minimum sensitivity
25 IU/L or equivalent units of HCG) within 48 hours prior to transplant (and the first
dose of study drug intraoperatively).Women must not be breast-feeding
