SIDE EFFECTS

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The safety of co-administering leuprolide acetate for depot suspension and norethindrone acetate was evaluated in two clinical studies in which a total of 242 women were treated for up to one year. Women were treated with monthly IM injections of leuprolide acetate 3.75 mg (13 injections) alone or monthly IM injections of leuprolide acetate 3.75 mg (13 injections) and 5 mg norethindrone acetate daily. The population age range was 17-43 years old. The majority of patients were Caucasian (87%).

One study was a controlled clinical trial in which 106 women were randomized to one year of treatment with leuprolide acetate for depot suspension alone or with leuprolide acetate for depot suspension and norethindrone acetate. The other study was an open-label single arm clinical study in 136 women of one year of treatment with leuprolide acetate for depot suspension and norethindrone acetate, with follow-up for up to 12 months after completing treatment.

Adverse Reactions (>1%) Leading To Study Discontinuation

In the controlled study, 18% of patients treated monthly with leuprolide acetate and 18% of patients treated monthly with leuprolide acetate plus norethindrone acetate discontinued therapy due to adverse reactions, most commonly hot flashes (6%) and insomnia (4%) in the leuprolide acetate alone group and hot flashes and emotional lability (4% each) in the leuprolide acetate and norethindrone group.

In the open label study, 13% of patients treated monthly with leuprolide acetate plus norethindrone acetate discontinued therapy due to adverse reactions, most commonly depression (4%) and acne (2%).

Common Adverse Reactions

Table 1 lists the adverse reactions observed in at least 5% of patients in any treatment group, during the first 6 months of treatment in the add-back clinical studies, in which patients were treated with monthly leuprolide acetate for depot suspension 3.75 mg with or without norethindrone acetate co-treatment. The most frequently-occurring adverse reactions observed in these studies were hot flashes and headaches.

In the controlled clinical trial, 50 of 51 (98%) patients in the leuprolide acetate alone group and 48 of 55 (87%) patients in the leuprolide acetate and norethindrone group reported experiencing hot flashes on one or more occasions during treatment. Table 2 presents hot flash data in the sixth month of treatment.

Serious Adverse Reactions

Urinary tract infection, renal calculus, depression

Changes In Laboratory Values During Treatment

Liver Enzymes

In the two clinical trials of women with endometriosis, 4 of 191 patients receiving leuprolide acetate and norethindrone acetate for up to 12 months developed an elevated (at least twice the upper limit of normal) SGPT and 2 of 136 developed an elevated GGT. Five of the 6 increases were observed beyond 6 months of treatment. None was associated with an elevated bilirubin concentration.

Lipids

Percent changes from baseline for serum lipids and percentages of patients with serum lipid values outside of the normal range in the two studies of leuprolide acetate and norethindrone acetate are summarized in the tables below. The major impact of adding norethindrone acetate to treatment with leuprolide acetate for depot suspension was a decrease in serum HDL cholesterol and an increase in the LDL/HDL ratio.

Changes from baseline tended to be greater at Week 52. After treatment, mean serum lipid levels from patients with follow up data (105 of 158 patients) returned to pretreatment values.

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of leuprolide acetate for depot suspension or norethindrone acetate. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Leuprolide Acetate For Depot Suspension

During postmarketing surveillance with other dosage forms and in the same or different populations, the following adverse reactions were reported:

  • Allergic reactions (anaphylactic, rash, urticaria, and photosensitivity reactions)
  • Mood swings, including depression
  • Suicidal ideation and attempt
  • Symptoms consistent with an anaphylactoid or asthmatic process
  • Localized reactions including induration and abscess at the site of injection
  • Symptoms consistent with fibromyalgia (e.g., joint and muscle pain, headaches, sleep disorders, gastrointestinal distress, and shortness of breath), individually and collectively
Other Adverse Reactions Reported Are

Hepato-biliary disorder – Serious liver injury

Injury, poisoning and procedural complications – Spinal fracture

Investigations – Decreased white blood count

Musculoskeletal and connective tissue disorder – Tenosynovitis-like symptoms

Nervous System disorder – Convulsion, peripheral neuropathy, paralysis

Vascular disorder – Hypotension, Hypertension

Serious venous and arterial thrombotic and thromboembolic events, including deep vein thrombosis, pulmonary embolism, myocardial infarction, stroke, and transient ischemic attack

Pituitary Apoplexy

During post-marketing surveillance, cases of pituitary apoplexy (a clinical syndrome secondary to infarction of the pituitary gland) have been reported after the administration of leuprolide acetate and other GnRH agonists. In a majority of these cases, a pituitary adenoma was diagnosed, with a majority of pituitary apoplexy cases occurring within 2 weeks of the first dose, and some within the first hour. In these cases, pituitary apoplexy has presented as sudden headache, vomiting, visual changes, ophthalmoplegia, altered mental status, and sometimes cardiovascular collapse. Immediate medical attention has been required.
