Terminal: 21 hours
Use: Labeled Indications
Note: Not approved in the US
Infertility: Stimulation of follicular development in infertile hypogonadotropic hypogonadal (HH) women with profound luteinizing hormone (LH) deficiency (<1.2 units/L); to be used in combination with follitropin alfa
Hypersensitivity to lutropin alfa or any component of the formulation; primary ovarian failure; uncontrolled thyroid or adrenal dysfunction; active, untreated tumors of the hypothalamus and pituitary gland; ovarian, uterine, or breast cancer; abnormal uterine bleeding of undetermined origin; ovarian cyst or enlargement unrelated to polycystic ovarian disease and of undetermined origin; malformations of sexual organs incompatible with pregnancy; fibroid tumors of the uterus incompatible with pregnancy; pregnancy; breast-feeding
Infertility: Females (≥16 years to ≤60 years): SubQ: 75 units daily until adequate follicular development is noted (maximum dose: 75 units daily); maximum duration of treatment: 14 days, unless signs of imminent follicular development are present. Duration of stimulation may be extended in any one cycle up to 5 weeks (treatment should be individualized based on response to prior cycle). Administer concomitantly with follitropin alfa. Administer hCG one day after the last dose of lutropin alfa and follitropin alfa. Encourage patients to have daily intercourse beginning the day prior to hCG administration and until ovulation is apparent. If the ovaries are abnormally enlarged or if abdominal pain occurs, withhold hCG, discontinue lutropin alfa and follitropin alfa, and advise patient to avoid intercourse.

Concerns related to adverse effects:
• Neoplasm: Benign and malignant neoplasms have been reported with multiple drug infertility treatment; causative association between gonadotropin therapy and increased risk of malignancy has not yet been established.
• Ovarian enlargement: May be accompanied by abdominal distention or abdominal pain and generally regresses without treatment within 2 to 3 weeks; more common in women with polycystic ovarian syndrome. If ovaries are abnormally enlarged on the last day of treatment, withhold hCG to reduce the risk of ovarian hyperstimulation syndrome (OHSS).
• Ovarian hyperstimulation syndrome (OHSS): OHSS, an exaggerated response to ovulation induction therapy, is characterized by an increase in vascular permeability, which causes a fluid shift from intravascular space to third-space compartments (eg, peritoneal cavity, thoracic cavity) (ASRM, 2008; SOGC-CFAS, 2011). This syndrome may begin within 24 hours of treatment, but may become most severe 7 to 10 days after therapy (SOGC-CFAS, 2011). OHSS is typically self-limiting with spontaneous resolution, although it may be more severe and protracted if pregnancy occurs (ASRM, 2008). Symptoms of mild/moderate OHSS may include abdominal distention/discomfort, diarrhea, nausea, and/or vomiting. Severe OHSS symptoms may include abdominal pain that is severe, acute respiratory distress syndrome, anuria/oliguria, ascites, dyspnea, hypotension, nausea/vomiting (intractable), pericardial effusions, tachycardia, or thromboembolism. Decreased creatinine clearance, hemoconcentration, hypoproteinemia, elevated liver enzymes, elevated WBC, and electrolyte imbalances may also be present (ASRM, 2008; Fiedler, 2012; SOGC-CFAS, 2011). If severe OHSS occurs, stop treatment and consider hospitalizing the patient. (ASRM, 2008; SOGC-CFAS, 2011). Treatment is primarily symptomatic and includes fluid and electrolyte management, analgesics, and prevention of thromboembolic complications (ASRM, 2008; SOGC-CFAS, 2011). The ascitic, pleural, and pericardial fluids may be removed if needed to relieve symptoms (eg, pulmonary distress, cardiac tamponade) (ASRM, 2008; SOGC-CFAS, 2011). Women with OHSS should avoid pelvic examination and/or intercourse (ASRM, 2008; SOGC-CFAS, 2011).
• Thromboembolism: In association with and separate from ovarian hyperstimulation syndrome (OHSS), thromboembolic events have been reported.
• Porphyria: Gonadotropins may increase the risk of an acute porphyric attack in patients with porphyria or a family history of porphyria; discontinuation of therapy may be necessary with onset or worsening of condition.
• Elderly: Not indicated for use in females >60 years of age.
• Pediatric: Not indicated for use in females <16 years of age.
• Appropriate use: To minimize risks, use only at the lowest effective dose. Monitor ovarian response with serum estradiol and vaginal ultrasound on a regular basis.
• Experienced physician: These medications should only be used by physicians who are thoroughly familiar with infertility problems and their management.
• Multiple births: May result from the use of these medications; advise patients of the potential risk of multiple births before starting the treatment. Discontinuation of therapy is recommended if there is a high risk for multiple pregnancies.
Prior to therapy: Baseline LH <1.2 units/L, FSH <5 units/L
Monitor sufficient follicular maturation. This may be directly estimated by sonographic visualization of the ovaries and endometrial lining or measuring serum estradiol levels. The combination of both ultrasonography and measurement of estradiol levels is useful for monitoring for the growth and development of follicles and timing hCG administration.
The clinical evaluation of estrogenic activity (changes in vaginal cytology and changes in appearance and volume of cervical mucus) provides an indirect estimate of the estrogenic effect upon the target organs and, therefore, it should only be used adjunctively with more direct estimates of follicular development (ultrasonography and serum estradiol determinations).
The clinical confirmation of ovulation is obtained by direct and indirect indices of progesterone production. The indices most generally used are: rise in basal body temperature, increase in serum progesterone, and menstruation following the shift in basal body temperature. Sonographic evidence of ovulation includes collapsed follicle, fluid in the cul-de-sac, ovarian stigmata, and secretory endometrium.
Monitor for signs and symptoms of OHSS for at least 2 weeks following hCG administration.
OHSS: Monitoring of hospitalized patients should include abdominal circumference, albumin, cardiorespiratory status, electrolytes, fluid balance, hematocrit, hemoglobin, serum creatinine, urine output, urine specific gravity, vital signs, weight (all daily or as necessary) and liver enzymes (weekly) (ASRM, 2008; SOGC-CFAS, 2011).
Adverse events have been observed in animal reproduction studies. Ectopic pregnancy, miscarriage, spontaneous abortion, and multiple births have been reported. The incidence of congenital abnormality may be slightly higher after assisted reproductive techniques than with spontaneous conception; higher incidence may be related to parenteral characteristics (maternal age, sperm characteristics). Lutropin alfa is used to stimulate follicular development; use is contraindicated in women who are already pregnant.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience injection site irritation, headache, flatulence, constipation, loss of strength and energy, diarrhea, or nausea. Have patient report immediately to prescriber signs of blood clots (numbness or weakness on one side of the body; pain, redness, tenderness, warmth, or swelling in the arms or legs; change in color of an arm or leg; angina; shortness of breath; fast heartbeat; or coughing up blood), signs of ovarian hyperstimulation syndrome (severe abdominal pain or bloating; severe nausea, vomiting, or diarrhea; excessive weight gain; shortness of breath; or change in how much urine is passed), breast pain, enlarged breasts, blue or pale skin on arms or legs (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
