A phase II trial of a novel platinum analog, SKI 2053R, was performed in patients with previously untreated extensive-stage disease (ED) small-cell lung cancer (SCLC). SKI 2053R was administered at the dose of 400 mg/m2 every 3 to 4 weeks as a 1-h infusion. After the first cycle, the dose was escalated to 440 mg/m2 based on toxicity. Thirty-eight patients (31 male) were enrolled between June 1995 and August 1997. The median age was 61 years (range, 36-70 years). Six of 37 evaluable patients achieved a partial response (16.2%; 95% confidence interval [CI], 4.4-28.0%). The durations of response were 1.1, 1.5, 1.7, 1.9, 3.4, and 4.6 months. The estimated median survival time was 7.4 months (95% CI, 5.1-9.7 months). Grade 3 or 4 toxicities were not observed. Grade 1 to 2 leukopenia, anemia, and thrombocytopenia were seen in 5 of 68 cycles, 16 of 68, and 2 of 68, respectively. Nonhematologic toxicities included grade 1 to 2 nausea or vomiting (30 of 68 cycles), nephrotoxicity (27 of 68), and hepatotoxicity (13 of 68). SKI 2053R showed a modest antitumor activity with limited toxicities in patients with ED SCLC. Further clinical trials are warranted in SCLC with a higher dose of SKI 2053R.

Bosutinib (SKI-606) is a 4-anilino-3-quinoline carbonitrile, which acts as a dual inhibitor of Src and ABL kinases. In addition, the BCR-ABL fusion gene product, a constitutively activated tyrosine kinase which is crucial for the development of chronic myeloid leukemia (CML), is highly sensitive to bosutinib. Interestingly, distinctly lower concentrations of bosutinib are required to ablate BCR-ABL phosphorylation when compared to the first-generation tyrosine kinase inhibitor imatinib (IM). Bosutinib is a potent inhibitor of CML cell proliferation in vitro and has demonstrated promising activity in CML patients resistant or intolerant to IM as well as in newly diagnosed patients with chronic phase CML (CML-CP). Remarkably, bosutinib has been found to be capable of overcoming the majority of IM-resistant BCR-ABL mutations. Bosutinib has the potency to induce deep and fast responses in second- and third-/fourth-line treatment, and as a consequence, the drug has recently been licensed for patients previously treated with one or more tyrosine kinase inhibitor(s) and for whom imatinib, nilotinib, and dasatinib are not considered appropriate treatment options. Due to its potency and differing toxicity profile, it promises to be a good therapeutic option for a defined cohort of patients. The most common side effects are gastrointestinal with most of the patients suffering from nausea, vomiting, or diarrhea. For the most part, these gastrointestinal symptoms occur early after treatment initiation, are manageable, and often self-limiting. Continuous monitoring of liver enzymes upon treatment initiation is necessary during bosutinib treatment. In addition to CML treatment, bosutinib has shown some efficacy in selected patients suffering from advanced-stage solid tumors. In conclusion, bosutinib is a promising novel small molecule inhibitor approved now for targeted therapy of CML and in clinical development for other malignancies.
