A PHASE I TRIAL OF COMBINATION CHEMOTHERAPY WITH IRINOTECAN(CPT-II), CISPLATIN AND VINDESINE IN ADVANCED NON-SMALL CELL LUNG CANCER (NSCLC) N.Nomura. T.Shiokai, T.Yajima. M.Aodoh. JShiraishi, N.Yamamoto, M.Fukuda. H.Arioka, F.Oshita, Y.Ohe, T.Tamura. K.Eguchi, NSaijo National Cancer Center.Tokyo. Japan. In order to evaluate the potential benefit of the additioo of Cm-11 to cisplatin and vindesioe, we conducted two combination phase I studies with high-dose cisplatin (100mg/m2 : 1st trial) and low-dose cisplatin(6Omg/m2 : 2nd trial) in patients @ts) with advanced NSCLC. Sixteen sod 25 pts have been accrued. respectively. CPT-11 was given on days 188 in combination with cisplatin (dl) and vindesine (3mg&Z dl&8). In the fust study, the starting dose of CPT-11 was 2Smgfm2 and the dose was escalated in incremenu of 12Smg/m2. In the second study, the starting dose was 2Omg/m2 and the escalated dose was ZOmg/mZ at each level. The dose limiting toxicities were gmmdocytopxia and diarrhea In the combination of CPT-11, cisplatin and vindesine. the recommended doses of CPT-11 mmbined with high- and low-dose cisplatin for phase IJ trial were 3l.SmgIto2 and 8Omglm2 on days l&8. respectively.
PHASE II STUDIES OF TOPOTECAN IN PATIENTS WITH NON-SMALL CELL LUNG CANCER (NSCLC) PREVIOUSLY UNTREATED AND PATIENTS WITH SMALL CELL LUNG (SCLC) CANCER REFRACTORY TO ETOPOSIDE. R. Perez-Soler, B.S. Glisson, J. Kane, J.S. Lee, J. Lee, M.N. Raber, W.K. Hong. M.D. Anderson Cancer Center, Houston, TX 77030 Topotecau is a hydrosoluble semisynthetic analogue of the topoisomerase I inhibitor camptothecin that has shown activity in NSCLC in Phase I studies and in untreated SCLC in Phase II studies. Phase II clinical trials of Topotecan in pts with metastatic NSCLC previously untreated and pts with SCLC refractory to etoposide are in progress. Topotecan is administered i.v. as a 30 min daily infusion for 5 consecutive days at a dose of 1.5 mg/ma/day (NSCLC) or 1.25 mg/mVday (SCLC). Thirty seven pts (NSCLC) and 16 pts (SCLC) are evaluable for response and toxicity. In the NSCLC study, 5 pts have achieved a partial remission (PR) (overal response rate 13.5%. duration 2,12+, 6,5+, and 2+ months) and 3 pts (8%) a minor responseThe difference in PR rate between squamous and adenoca pts is statistically significant (4/l 1 vs l/17, p= 0.04). In the SCLC study, 3 pts have achieved a PR (19% duration 1.2, and +2 months) and 1 pt (6%) a minor response. Grade 3 or 4 toxicities have been limited to myelosuppression (grade 3 or 4 granulocytopenia in 81% of cycles, grade 3 or 4 thrombocytopenia in 13% of cycles) lasting <7 days in most cases. No toxic deaths or withdrawals due to toxicity have occurted. Other toxicities include alopecia in all pts and grade 1 or 2 nausea and vomiting in about 50% of patients. The results indicate that Topotecan 1) is easily tolerated, 2) has moderate activity in previously untreated NSCLC pts, squamous ca pts being most sensitive, and 3) has definite activity in SCLC pts that are refractory to the topoisomerase II active drug etoposide.

At the first level (P 135 mg/m2 and C 100 mg/m2) no toxicity was observed among the 3 treated patients, except for moderate alopecia and mild nausea and/or vomiting.

We conclude that this regimen can be administrated safely and have shown some activity in NSCLC (specialy in squamous cell carcinoma). However, VP 16 does not seem to increase RR compare to the classical PFL combination (29 % RR).
