This is a Phase I/safety dose expansion study of the combination of the drug ganetespib and doxorubicin in patients with advanced solid tumors. The purpose of the Phase I part of the study is to determine the recommended phase II dose of ganetespib when given in combination with doxorubicin. The recommended Phase II dose determined at the end of the dose escalation phase will be used to conduct a safety dose expansion phase in relapsed/refractory small cell lung cancer to determine if there is a signal of efficacy in this population.

The dose escalation phase of the study will follow a standard 3+ 3 dose escalation scheme with two dose levels of ganetespib (1-- mg/m2 and 150 mg/m2) administered weekly on Days 1 and 8 of a 21-day cycle, in combination with a fixed dose of doxorubicin at 50 mg/m2 administered on Day 1 alone. After 4-6 cycles of combination therapy, continuation of single agent ganetespib will be permitted for subjects who are deriving clinical benefit.

Pharmacokinetic samples for plasma drug levels of ganetespib will be collected pre-dose and 4 hours after completion of treatment on Day 1 and Day 8 of cycle 1 only in subjects in the dose escalation phase.

The recommended Phase II dose determined at the end of the dose escalation phase will be used to conduct a safety dose expansion phase in relapsed/ refractory small cell lung cancer to determine if there is a signal of efficacy in this population.

Inclusion Criteria:

• Dose escalation phase: histologically confirmed malignancy that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective. OR safety dose expansion phase: histologically or cytologically confirmed relapsed or refractory small cell lung cancer
• No more than 3 prior lines of chemotherapy; prior therapy with doxorubicin is permitted but no more than lifetime cumulative dose of 150 mg/m2; at least 3 weeks since prior chemotherapy or radiotherapy; at least 6 weeks if the last regimen included BCNU (1,3-bis(2-chloroethyl)-1-nitrosourea bis-chloronitrosourea) or mitomycin C
• Age >/= 18 years
• ECOG (Eastern Cooperative Oncology Group) performance status 0-1
