* Alkaline phosphate \< 2.5 x ULN
Renal:
* Creatinine \< 1.5 x ULN
Cardiovascular:
* No history of myocardial infarction or angina pectoris or angina equivalent within 6 months prior to registration for protocol therapy (the patient may not be on anti-anginal or anti-arrhythmic medications), or have uncontrolled hypertension or congestive heart failure \> class II NYHA
Pulmonary:
* No thrombolic or embolic events such as a cerebrovascular accident, including transient ischemic attacks within the past 6 months.
* No pulmonary hemorrhage/bleeding event \> CTCAE Grade 2 within 28 days prior to registration for protocol therapy.

- Primary Outcome Measures
Name Time Method Maximum Tolerated Dose (MTD) Each participant was treated at their assigned dose level on 28 day cycles until disease progression or unacceptable toxicity. Participants were evaluated for toxicity every two weeks. An initial 3 patients will be enrolled at dose level 1. If all 3 patients in dose level 1 complete the first cycle of therapy without a dose limiting toxicity (DLT), 3 patients will be enrolled at dose level 2. If 0 of 3 or 1 of 6 patients in dose level 2 experience a DLT, all subsequent patients will be enrolled in the Phase II cohort at dose level 2. If 2 of the first 3 or 2 of the total 6 patients experience DLT at dose level 2, then dose level 1 will be considered the MTD and used in the second phase.
Percentage of Participants With Response Disease assessments were conducted on the 8th week (Cycle 2, Week 4) and every eight weeks there after, until treatment discontinuation To assess response in patients with recurrent or resistant epithelial ovarian cancer treated with Sorafenib plus Topotecan. Reponse evaluated per RECIST criteria where:
Complete Response (CR): Disappearance of all target lesions Partial Response (PR): At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started
- Secondary Outcome Measures
Name Time Method Clinical Benefit From enrollment until treatment discontinuation. Participants may remain on study drug indefinitely To determine the rate of clinical benefit defined as the percentage of patients experiencing an objective response or a CA125 response.
Duration of Stable Disease From enrollment until treatment discontinuation. Participants may remain on study drug indefinitely To determine duration of stable disease, in months
Progression-free Survival From enrollment until treatment discontinuation. Participants may remain on study drug indefinitely To determine the progression-free survival of patients treated with Sorafenib plus Topotecan.
