SIDE EFFECTS

The following most serious adverse reactions are described elsewhere in other labeling sections:

  • Hepatic Adverse Reactions.
  • Anaphylactic and Hypersensitivity Reactions.

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 practice.

Clinical Trials Experience In Adults

The safety of ERAXIS for Injection was assessed in 929 individuals, including 257 healthy subjects and 672 patients in clinical trials of candidemia, other forms of Candida infections, and esophageal candidiasis. A total of 633 patients received ERAXIS at daily doses of either 50 mg or 100 mg. A total of 481 patients received ERAXIS for ≥14 days.

Candidemia/other Candida Infections

Three trials (one comparative vs. fluconazole, two non-comparative) assessed the efficacy and safety of ERAXIS (100 mg) in patients with candidemia and other Candida infections.

The data described below reflect exposure to ERAXIS and fluconazole in 127 and 118 patients, respectively, with candidemia and other forms of invasive candidiasis, in the randomized, comparative trial of the efficacy and safety of ERAXIS to that of fluconazole. In ERAXIS-treated patients, the age range was 16-89 years, the gender distribution was 51% male and 49% female, and the race distribution was 72% White, 18% Black/African American, 9% other races. Patients were randomized to receive once daily IV ERAXIS (200 mg loading dose followed by 100 mg maintenance dose) or IV fluconazole (800 mg loading dose followed by 400 mg maintenance dose). Treatment was administered for at least 14 and not more than 42 days.

The number of patients with adverse reactions leading to discontinuation of study medication was 11.5% in the ERAXIS arm and 21.6% in the fluconazole arm. The most common adverse reactions leading to study drug discontinuation were multi-organ failure (2.3%) and systemic Candida infection (1.5%) in the ERAXIS arm.

Table 2 presents adverse reactions that were reported in ≥5% of subjects receiving ERAXIS or fluconazole therapy in this trial.

Esophageal Candidiasis

The data described below reflect exposure to ERAXIS and fluconazole in 300 and 301 patients, respectively, with esophageal candidiasis in a randomized trial comparing the efficacy and safety of ERAXIS to that of oral fluconazole. In ERAXIS-treated patients, the age range was 18-68 years, the gender distribution was 42% male and 58% female and the race distribution was 15% White, 49% Black/African American, 15% Asian, 0.3 % Hispanic, 21% other races. Patients were randomized to receive IV ERAXIS (100 mg on day 1, followed by 50 mg per day) or oral fluconazole (200 mg on day 1, followed by 100 mg per day) for 7 days beyond resolution of symptoms (range, 14-21 days).

Twenty-eight (9%) patients in the ERAXIS arm and 36 (12%) patients in the fluconazole arm had adverse reactions related to study medication. The most common adverse reactions leading to study discontinuation were maculopapular rash (1 patient) for the ERAXIS arm. The most common adverse reactions leading to discontinuation were rash (1 patient) and increased AST (1 patient) for the fluconazole arm.

Clinical Trials Experience In Pediatric Patients With Candidemia/Invasive Candidiasis

The safety of ERAXIS was investigated in 68 pediatric patients from 1 month to less than 18 years of age with candidemia/invasive candidiasis in a prospective, open-label, non-comparative pediatric trial [see Clinical Studies]. Overall, the safety profile of ERAXIS in the pediatric patients 1 month and older was similar to that of adults.

Post-Marketing Experience

The following adverse reactions have been identified during post approval use of anidulafungin. 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.

Immune: Anaphylactic shock, anaphylactic reaction, bronchospasm.
