Approved 11 Oct 2007OralCapsule

The FDA lists this product in 3 strengths and forms.

Indications

HYCAMTIN ® capsules are indicated for the treatment of relapsed small cell lung cancer (SCLC) in patients with a prior complete or partial response and who are at least 45 days from the end of first-line chemotherapy. HYCAMTIN capsules is a topoisomerase inhibitor indicated for treatment of patients with relapsed small cell lung cancer (SCLC). ( 1 )

Contraindications

HYCAMTIN is contraindicated in patients who have a history of severe hypersensitivity reactions to topotecan. Reactions have included anaphylactoid reactions [see Adverse Reactions (6.2)] .

History of severe hypersensitivity reactions to topotecan ( 4 )

Warnings and precautions

Diarrhea: Severe diarrhea can occur. Withhold and reduce dose as recommended. ( 2.2 , 5.2 )
Interstitial Lung Disease (ILD): Fatal cases have occurred. Permanently discontinue if confirmed ILD. ( 5.3 )
Embryo-Fetal Toxicity: Can cause fetal harm. Advise patients of potential risk to the fetus and to use effective contraception. ( 5.4 , 8.1 , 8.3 )

5.1Myelosuppression

HYCAMTIN can cause severe myelosuppression. The following safety data are based on an integrated safety database from four trials in patients with lung cancer (N = 682) who received HYCAMTIN capsules at a dose of 2.3 mg/m 2 orally once daily for 5 consecutive days, starting on Day 1 of a 21-day cycle. The median day for neutrophil and platelet nadirs occurred on Day 15. Grade 4 neutropenia occurred in 32% of the 682 patients, with a median duration of 7 days.

Grade 4 neutropenia most commonly occurred during cycle 1 (20% of patients). Clinical sequelae of neutropenia included infection (17%), febrile neutropenia (4%), sepsis (2%), and septic death (1%). Grade 4 thrombocytopenia occurred in 6%, with a median duration of 3 days. Grade 3 or 4 anemia occurred in 25%. HYCAMTIN can cause fatal typhlitis (neutropenic enterocolitis). Consider the possibility of typhlitis in patients presenting with fever, neutropenia, and abdominal pain.

Administer the first cycle of HYCAMTIN capsules only to patients with a baseline neutrophil count greater than or equal to 1,500/mm 3 and a platelet count greater than or equal to 100,000/mm 3 . Monitor blood cell counts frequently during treatment. Withhold and reduce dose of HYCAMTIN capsules based on neutrophil counts, platelet counts and hemoglobin levels [see Dosage and Administration (2.2)] .

Adverse reactions

The following serious adverse reactions are described elsewhere in the labeling:

Myelosuppression [see Warnings and Precautions (5.1)]
Diarrhea [see Warnings and Precautions (5.2)]
Interstitial Lung Disease (ILD) [see Warnings and Precautions (5.3)]

6.1Clinical 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data in the Warnings and Precautions and below reflects exposure to HYCAMTIN capsules in 682 patients with recurrent lung cancer enrolled in four randomized, open label trials, including 275 patients with small lung cell lung cancer (SCLC) (Studies 478, 065 and 396), and 407 patients with non-small cell lung cancer (NSCLC) (Study 387), who received at least one dose of HYCAMTIN capsules.

Patients in these trials had advanced lung cancer and received prior chemotherapy in the first-line setting. Patients received HYCAMTIN capsules 2.3 mg/m 2 orally once daily for 5 consecutive days, starting on Day 1 of a 21-day cycle. The median number of cycles was 3 (range: 1 to 20). The safety of HYCAMTIN capsules was evaluated in a randomized trial (Study 478) conducted in 70 patients with recurrent SCLC [see Clinical Studies (14)] .

In the 682 patients who received HYCAMTIN capsules in the four lung cancer trials, 39 deaths (6%) occurred within 30 days after the last dose for a reason other than progressive disease: 13 due to hematologic toxicity, 5 due to non-hematologic toxicity (2 from diarrhea), and 21 due to other causes. Table 1 describes the hematologic and non-hematologic adverse reactions that occurred in greater than 5% of patients treated with HYCAMTIN capsules in these trials.

6.2Postmarketing Experience

The following reactions have been identified during post approval use of HYCAMTIN. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Gastrointestinal: Gastrointestinal perforation General and Administration Site Conditions: Mucosal inflammation Hypersensitivity: Allergic manifestations, anaphylactoid reactions, angioedema
