BIBF 1120 as Second Line Treatment for Small Cell Lung Cancer
Although chemotherapy is the primary treatment option for small cell lung cancer (SCLC), longterm survival is rare. SCLC is initially chemosensitive, but rapidly relapses in a chemoresistant form with an overall survival of <5%. Consequently, novel therapies are urgently required and will likely arise from an improved understanding of the disease biology. Some preclinical studies have showed that fibroblast growth factor-2 induces proliferation and

Chemotherapy is the primary treatment option for patients with small cell lung cancer (SCLC), leading to a 5-year survival of about 20% in limited disease (LD), and less than 5% in extensive disease (ED). Although initial tumor response rate to chemotherapy is very high (up to 96% for LD and up to 65% in ED), SCLC relapses in approximately 4 months in ED and 12 months in LD. Despite the administration of second-line chemotherapy, the overall median survival of patients with limited and extensive disease is approximately 18 and 9 months, respectively. In the setting of second-line therapy, response rates to chemotherapy range between 15 and 25%, with median survival in the range of 4-6 months. Second-line therapeutic options include cyclophosphamide, doxorubicin and vincristine (CAV) given every 3 weeks or topotecan, which have similar response rates, time to progression and survival in the two treatment arms (topotecan 24%, 13 and 24.7 weeks; CAV 18%, 12 and 22 weeks, respectively). However, both treatments have substantial toxicities, with 9% of patients on trial withdrawing for toxicity reasons. Treatment-associated mortality was as high as 4.7% (possibly and definitely related), and many patients required transfusion support. Thus, while these treatments have acceptable activity second-line, more active and less toxic treatments are required for this patient population.
The next generation of anti-angiogenic drugs aims to improve clinical efficacy by targeting multiple angiogenic factors. This approach was validated by a recent analysis of BIBF 1120, which inhibits vascular endothelial growth factor receptors (VEGFRs), platelet-derived growth factor receptors (PDGFRs) and the fibroblast growth factor receptors (FGFRs). BIBF 1120 resulted in growth inhibition of tumours in syngeneic rats and human tumour xenografts in nude mice. It also displayed a favourable cellular duration of action and pharmacodynamic profile and was well-tolerated. These data complement early-phase clinical data suggesting that BIBF 1120 might be an effective anti-angiogenic agent. Some preclinical studies have showed that fibroblast growth factor-2 induces proliferation and chemoresistance in SCLC cells. In addition, the selective fibroblast growth factor receptor (FGFR) inhibitor PD173074 blocks H-510 and H-69 SCLC proliferation and clonogenic growth in a dose-dependent fashion and prevents FGF-2-induced chemoresistance. BIBF1120 is a novel, orally available, potent triple angiokinase inhibitor that predominantly blocks the FGFR in addition to vascular endothelial growth factor (VEGF) and platelet-derived growth factor receptor (PDGFR). Therefore, the investigators will conduct a phase II trial to evaluate the efficacy of BIBF1120 in patients with recurrent SCLC.
