In vitro, the combination of interleukin-2 (Il-2) with interferon-alpha (IFN-alpha) seems to act synergistically on the generation of lymphokine activated killer (LAK) cells. Due to this fact two clinical trials with the combination of Il-2 and IFN-alpha were initiated in malignant melanoma (MM) and renal cell cancer (RCC). Patients with disseminated MM were treated by a sequential application of 10 x 10(6) U/m2 rIFN-alpha 2b s.c. on days 1-7 followed by continuous intravenous infusion of 3 x 10(6) U/m2 rIl-2 on days 8-13 and 15-20. After a pause of 4 weeks the cycle was repeated. In advanced or disseminated RCC, the patients were treated with a daily alternating scheme of 10 x 10(6) U/m2 rIFN-alpha and rIl-2 as 1 h infusion 1 x /day for 14 days. The rIl-2 escalates intra- and interindividually beginning with a dose of 3 x 10(6) U/m2. The cycles were repeated after a pause of 3 and 4 weeks, respectively. The preliminary results show that the schedules are practicable and that the toxicity of the combination of rIl-2 and IFN-alpha does not accumulate. Within the MM group 3/11 evaluable patients achieved partial remission and 2/11 stable disease. In the RCC-group 2/5 evaluable patients achieved partial remission and 2/5 had stable disease so far.
在体外,白细胞介素-2(Il-2)与α干扰素(IFN-α)联合使用似乎对淋巴因子激活的杀伤细胞(LAK细胞)的生成具有协同作用。基于这一事实,开展了两项关于Il-2与IFN-α联合使用治疗恶性黑色素瘤(MM)和肾细胞癌(RCC)的临床试验。转移性MM患者在第1 - 7天接受皮下注射10×10⁶U/m²重组人α干扰素2b(rIFN-α 2b)的序贯治疗,随后在第8 - 13天和15 - 20天持续静脉输注3×10⁶U/m²重组人白细胞介素-2(rIl-2)。经过4周的间歇期后重复该周期。对于晚期或转移性RCC患者,采用每日交替方案,即10×10⁶U/m²的rIFN-α和rIl-2,每天1次,每次1小时静脉输注,共14天。rIl-2的剂量从3×10⁶U/m²开始,在个体内和个体间逐步递增。分别在3周和4周的间歇期后重复该周期。初步结果表明,该方案可行,且rIl-2与IFN-α联合使用的毒性不会累积。在MM组中,11例可评估患者中有3例达到部分缓解,2例病情稳定。在RCC组中,5例可评估患者中有2例达到部分缓解,2例目前病情稳定。
