Phase III Randomized Study of 4 Weeks of High-Dose Interferon-α-2b in Stage T2bNO, T3a-bNO, T4a-bNO, and T1-4N1a-2a (microscopic) Melanoma: A Trial of the Eastern Cooperative Oncology Group-American College of Radiology Imaging Network Cancer Research Group (E1697).

Purpose To test the efficacy of 4 weeks of intravenous (IV) induction with high-dose interferon (IFN) as part of the Eastern Cooperative Oncology Group regimen compared with observation (OBS) in patients with surgically resected intermediate-risk melanoma. Patients and Methods In this intergroup international trial, eligible patients had surgically resected cutaneous melanoma in the following categories: (1) T2bN0, (2) T3a-bN0, (3) T4a-bN0, and (4) T1-4N1a-2a (microscopic). Patients were randomly assigned to receive IFN α-2b at 20 MU/m2/d IV for 5 days (Monday to Friday) every week for 4 weeks (IFN) or OBS. Stratification factors were pathologic lymph node status, lymph node staging procedure, Breslow depth, ulceration of the primary lesion, and disease stage. The primary end point was relapse-free survival. Secondary end points included overall survival, toxicity, and quality of life. Results A total of 1,150 patients were randomly assigned. At a median follow-up of 7 years, the 5-year relapse-free survival rate was 0.70 (95% CI, 0.66 to 0.74) for OBS and 0.70, (95% CI, 0.66 to 0.74) for IFN ( P = .964). The 5-year overall survival rate was 0.83 (95% CI, 0.79 to 0.86) for OBS and 0.83 (95% CI, 0.80 to 0.86) for IFN ( P = .558). Treatment-related grade 3 and higher toxicity was 4.6% versus 57.9% for OBS and IFN, respectively ( P < .001). Quality of life was worse for the treated group. Conclusion Four weeks of IV induction as part of the Eastern Cooperative Oncology Group high-dose IFN regimen is not better than OBS alone for patients with intermediate-risk melanoma as defined in this trial.

Final results of a phase II clinical trial of weekly docetaxel in combination with capecitabine in anthracycline-pretreated metastatic breast cancer.

The addition of capecitabine to docetaxel on a 3-week schedule resulted in superior response rate, increased time to progression (TTP), and improved overall survival in patients with anthracycline-pretreated metastatic breast cancer (MBC). Because the toxicity profile of weekly docetaxel differs from the standard 21-day docetaxel schedule, we performed a phase I/II trial to test the efficacy and safety of weekly docetaxel in combination with capecitabine given for 14 days every 21 days. The phase I study identified the doses of docetaxel (30 mg/m2 weekly) and capecitabine (900 mg/m2 twice daily on days 1-14 every 21 days) used in phase II. Twenty female patients with measurable or assessable MBC were enrolled. Eighteen patients had previously received anthracyclines; 2 had contraindications to anthracyclines. Patients remained on study for a maximum of eight 3-week cycles or until tumor progression or unacceptable toxicity occurred; response assessments were scheduled after cycle 2, 5, and 8. Seventeen patients were assessed after cycle 2; 3 subjects (18%) had a partial response (PR), 9 had stable disease (53%; SD), and 5 patients (29%) had progressive disease (PD). Ten patients were assessable after cycle 5. Two patients (20%) had a PR, 5 patients (50%) had SD, and 3 patients (30%) had PD. The most common grade 3 toxicities were nail loss (45%), asthenia (30%), and hand-foot syndrome (30%), and toxicities led to study discontinuation in 10 patients. The median time to treatment failure was 10 weeks and median TTP was 26 weeks. The median duration of response was 9 weeks and the median duration of SD was 16 weeks. The median overall survival was 82 weeks. This schedule of weekly docetaxel in combination with day 1-14 capecitabine has activity; however, toxicity discourages the use of this schedule in lieu of the standard docetaxel/capecitabine regimen.

A phase II, open label, monotherapy study of liposomal doxorubicin in patients with metastatic malignant melanoma.

PURPOSE: This phase II study explored the efficacy and tolerability of pegylated liposomal doxorubicin (PLD) given on a 2 week schedule in patients with advanced malignant melanoma previously untreated by chemotherapy. PATIENTS AND METHODS: Patients with inoperable, advanced melanoma were treated with Pegylated liposomal doxorubicin (Caelyx) at a dose of 20 mg/m(2) every 2 weeks. Treatment cycles were repeated every 4 weeks for a maximum of 6 cycles. Patients with responding or stable disease at the end of study treatment, as assessed by using NCI CTG criteria, could continue PLD off-study. RESULTS: PLD administered as a 2 weekly IV infusion was well tolerated with mild infusion reactions usually associated with the first infusion. Myelosuppression was mild, as was nausea and vomiting. Palmar plantar erythrodysesthesia was also uncommon using this schedule. There were no objective responses seen in the 14 evaluable patients. Enrollment was stopped as per protocol, due to lack of activity. CONCLUSION: PLD was well tolerated using a 2 week schedule but failed to show any activity in chemotherapy naive patients with advanced malignant melanoma.
