We tested paclitaxel (Taxol) and low dose hydroxyurea as second line therapy in 30 patients with non-small cell lung cancer since both drugs are active against non-small cell lung cancer in other settings, and since hydroxyurea may reverse chemotherapy resistance by disrupting double minute chromosomes. Hydroxyurea 500 mg was given orally each Monday, Wednesday, Friday starting 1 week before paclitaxel, and continuing until removal from study. Paclitaxel 135 mg/m2 was given i.v. over > or = 1 h every 3 weeks with dexamethasone, diphenhydramine, and ranitidine. Patients could have paclitaxel doses escalated to 175 mg/m2 in course 2 and to 200 mg/m2 in course 3, where tolerated. Sixteen males and 14 females were treated. All patients had previously received a single cisplatin-based chemotherapy regimen and 23 had previously received radiotherapy. Twelve patients had adenocarcinomas, six had squamous cell carcinomas, and 12 had large cell carcinomas. Eight patients had Stage IIIb cancers and 22 had Stage IV. Paclitaxel doses were 135 mg/m2 in 56 courses, 175 mg/m2 in 24, and 200 mg/m2 in 15. Treatment was well tolerated. Median granulocyte nadirs were 2.5 (x 10(9)/l) for paclitaxel 135 mg/m2, 1.8 for 175 mg/m2, and 1.3 for 200 mg/m2. No patient developed febrile neutropenia, and none required a dose reduction. Two patients had reversible anaphylaxis. Other toxicities were quite tolerable. They included fatigue, myalgias, dizziness, paresthesias, diarrhea, alopecia, mucositis, flushing, headache, swollen red hands, and anxiety. One patient had a partial remission and 15 had stable disease (including six with minor responses). Median survival was 20 (95% CI, 12-34) weeks, with 19% of patients remaining alive at 1 year from initiation of treatment. This is a well-tolerated regimen with modest activity as second line chemotherapy for patients with non-small cell lung cancer previously treated with cisplatin regimens. Higher doses would be feasible and other strategies are now being explored.

A phase I/II study was carried out to determine the maximum tolerated dose of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) in combination with a fixed dose of carboplatin (area under the concentration-time curve = 6 by Calvert method) given on an every-3-week schedule to patients with non-small cell lung cancer (NSCLC). Cohorts of patients were entered at increasing dose levels of paclitaxel: six at dose level I (paclitaxel 150 mg/m2), six at dose level 2 (paclitaxel 175 mg/m2), 11 at dose level 3 (paclitaxel 200 mg/ m2), 21 at dose level 4 (paclitaxel 225 mg/m2), and five at dose level 5 (paclitaxel 250 mg/m2). The patients comprised 31 men and 18 women with a median age of 62 years (age range, 46 to 81 years) and a median Southwest Oncology Group performance status of I (range, 0 to 2). Twenty-three patients had unresectable stage III NSCLC and 26 had stage IV NSCLC. Fortynine patients and 176 treatment courses are evaluable for toxicity. Grade 4 neutropenia or grade 3 arthralgias/ myalgias or sensory neuropathy were the most significant toxicities of therapy. In addition, two patients (dose levels 2 and 3) experienced acute chest pain, flushing, and hypotension, and had electrocardiogram changes during the paclitaxel infusion; one had mild creatine phosphokidnase MB elevation. Both recovered uneventfully, were not re-treated with paclitaxel, and account for two of only four hospitalizations for toxicity management in this trial. At this time, 42 patients with objectively measurable disease are evaluable for responses: two complete responses and 24 partial responses (62% objective response rate) have been observed. These data imply that the maximum tolerated dose of paclitaxel is 250 mg/m2 with dose-limiting toxicity consisting primarily of grade 3 osteo/arthralgias-myalgias or cumulative sensory neuropathy; paclitaxel at a dose of 225 mg/m2 given by 3-hour infusion combined with carboplatin at a calculated target area under the concentration-time curve of 6 is a well-tolerated outpatient treatment regimen and highly active in NSCLC; myelosuppression is mild and rarely dose limiting. Most notably, paclitaxel appears to decrease carboplatin's pharmacodynamic effects on thrombopoiesis.

Epidermal Growth Factor (EGF) promotes tumor cell proliferation and survival upon binding to its receptor. We have developed a new active specific immunotherapy based on EGF deprivation. In the present paper, we show the results of a Phase I trial in 43 patients with advanced non-small cell lung cancer (NSCLC) who received the EGF vaccine. Patients who had already received first line therapy were randomized to receive a single or double dose of the EGF vaccine, weekly for four weeks and monthly thereafter. No significant toxicity was seen after vaccination. Adverse events consisted primarily of fever, chills, nausea, vomiting and flushing. Fifteen patients (39%) developed a good antibody response (GAR) against EGF. The geometric mean of the antibody titer was higher in the double dose group. EGF concentration was quantified in serum. An inverse correlation between anti-EGF antibody titers and EGF concentration was seen after immunization. Vaccinated patients achieved median survival times of 8.23 months from randomization. Patients who received the double dose of treatment showed a trend toward increased survival in comparison with patients who received the single dose. GAR and patients in whom the serum EGF decreased below the 168 pg/ml cut-off point had a significantly better survival when compared to poor responders or patients in which the EGF levels were not considerably reduced. Our results confirm the immunogenicity of the EGF vaccine in the treatment of patients with advanced stage NSCLC. Antibody titers and serum EGF levels appear to correlate with patient survival.
