2.1 Recommended Evaluation and Testing Before Initiating Proleukin

Conduct baseline hematologic, chemistry, renal and hepatic function tests. Additionally, evaluate cardiac ejection fraction, coronary artery disease as appropriate, pulmonary function with PFTs, and evaluate for renal, hepatic, and CNS impairment prior to initiating treatment with Proleukin [see Contraindications (4), Warnings and Precautions (5.1, 5.2)].

Verify pregnancy status of females of reproductive potential prior to initiating Proleukin [see Warnings and Precautions (5.6), Use in Specific Populations (8.1, 8.3)].

Recommended Dosage

Administer Proleukin in an inpatient hospital setting. An intensive care facility with specialists skilled in cardiopulmonary or intensive care medicine must be available [see Warnings and Precautions (5.1)].

The recommended dosage of Proleukin for metastatic renal cell carcinoma and metastatic melanoma is described in Table 1.

Administer Proleukin as an intravenous infusion after dilution [see Dosage and Administration (2.5)].

Administer pre-infusion medications and supportive treatment, as appropriate, prior to and during each infusion [see Dosage and Administration (2.3)]. Discontinue Proleukin for unacceptable toxicity [see Dosage and Administration (2.4)].

Table 1: Recommended Dosage of Proleukin

1 A maximum of 28 doses (2 cycles) per treatment course

Each course of therapy consists of the following:

Cycle 1

Days 1-5

600,000 IU/kg (0.037 mg/kg) every 8 hours; maximum of 14 doses1

Rest period

Days 6-14

Cycle 2

Days 15-19

600,000 IU/kg (0.037 mg/kg) every 8 hours; maximum of 14 doses1

Evaluate patients for response approximately 4 weeks after completion of a course of therapy and again immediately prior to the scheduled start of the next treatment course.

Additional courses of treatment may be administered to patients if there is a treatment response following the last course, and the patient did not experience any adverse reactions in previous course(s) that led to permanent discontinuation [see Dosage and Administration (2.4)].

Separate each treatment course by a rest period of at least 7 weeks from the date of hospital discharge.

2.3 Premedication and Supportive Medications

Premedicate patients with an antipyretic immediately prior to beginning Proleukin. Continue antipyretics during treatment as needed for fever [see Warnings and Precautions (5.1, 5.10)].

Administer prophylactic antibiotics per institutional guidelines prior to beginning Proleukin and throughout the treatment course for patients with indwelling central catheters [see Warnings and Precautions (5.3)].

Administer prophylactic medication for gastrointestinal irritation and bleeding during each Proleukin treatment course [see Adverse Reactions (6.1)].

Additional medications may be needed if patients experience hypotension, dyspnea, rigors, nausea, diarrhea, pruritis, or dermatitis [see Warnings and Precautions (5.1, 5.8, 5.9)].

2.4 Dosage Modifications for Adverse Reactions

No dose reduction for Proleukin is recommended for adverse reactions. In general, withhold or interrupt a dose or permanently discontinue Proleukin based on the severity of the adverse reaction as described in Table 2.

Withhold until urine output >10 mL/hour with a decrease of serum creatinine >1.5 mg/dL or normalization of serum creatinine

Renal failure requiring dialysis >72 hours

Permanently discontinue

2.5 Preparation and Administration


Reconstitute Proleukin using Sterile Water for Injection, USP. Do not reconstitute or dilute Proleukin with Bacteriostatic Water for Injection, or 0.9% Sodium Chloride Injection.

  • Add 1.2 mL of Sterile Water for Injection, USP, by injecting the water along the walls of the vial and not directly on the lyophilized powder. The resulting concentration is 18 million IU (1.1 mg)/mL of Proleukin.
  • The prepared solution is a clear, colorless to slightly yellow liquid.
  • Slowly swirl the vial; do not shake.
  • Withdraw the required dose of Proleukin and discard the vial with any unused portion.
  • Use polyvinyl chloride bags for dilution of Proleukin and dilute using 5% Dextrose Injection to a concentration between 0.03 mg/mL and 0.07 mg/mL based on the required dose as follows:
Table 3: Recommended Proleukin Dilution


5% Dextrose Volume

≤25.4 million IU (≤1.5 mg)

25 mL

>25.4 million IU-60 million IU (>1.5 mg-3.5 mg)

50 mL

>60 million IU (>3.5 mg)

100 mL

Storage of Diluted Proleukin Infusion Solution

  • Store under refrigeration at 2° to 8°C (36° to 46°F) for no more than 48 hours from the time of preparation to the end of the infusion.
  • Protect from light.
  • Do not freeze.
  • Allow the diluted solution to come to room temperature prior to administration.


  • Do not use in-line filters when administering Proleukin.
  • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
