objective response rate (ORR) [ Time Frame: 1 year ] LM objective response rate (ORR) is defined as the proportion of patients with at least one objective response in LM, using a combined approach taking into account radiographic, neurologic and cytologic assessments based on RANO-LM.

Brief Title ICMJE | A Study of Deferoxamine (DFO) in People With Leptomeningeal Metastasis | ||||||||
Official Title ICMJE | A Phase 1a/1b Trial of Intrathecal Deferoxamine for Leptomeningeal Metastases | ||||||||
Brief Summary | The researchers are doing this study to find out whether deferoxamine (DFO) given intrathecally (directly into the CSF) is a safe treatment for people with leptomeningeal metastasis from solid tumor cancer. The researchers will test different doses of DFO to find the highest dose that causes few or mild side effects. When the dose is found, they will test it in future participants to see whether DFO is a safe and effective treatment for people with leptomeningeal metastasis from non-small cell lung cancer (NSCLC). They are also doing this study to see how the body absorbs, distributes, gets rid of, and responds to DFO. | ||||||||
Detailed Description | Phase 1a During the phase 1a arm, the MTD and PK/PD data will be evaluated in patients with LM from any solid tumor malignancy in an accelerated dose escalation fashion, with conversion to a traditional 3 + 3 dose escalation scheme at either dosing cohort 5 or when alternative criteria is met [either 1 patient experiences a DLT or 2 patients experience any grade 2 or higher nervous system disorder toxicity (except headache)]. All patients will receive IT-DFO via Ommaya reservoir twice per week during cycle 1, once per week during cycle 2, and once every 2 weeks for subsequent cycles until LM progression, intolerable toxicity, or death. DLTs and new grade 2 or higher nervous system toxicities will be assessed for the first 28 days of each cohort. Patients will undergo PK/PD assessments at the time of C1-3 doses 1 and 2 (six dosing time points) to evaluate changes iron, DFO, and ferrioxamine concentrations in the blood and CSF at each dosing cohort. The Principal Investigator will consider the MTD determined by the dose escalation, any cumulative or delayed CNS toxicities (if present), and PK/PD data of phase 1a when determining the RP2D of phase 1b. Phase 1b The phase 1b dose expansion will be determined by the RP2D of the phase 1a arm, and will be restricted to patients with NSCLC. All patients will receive IT-DFO via Ommaya reservoir twice per week during cycle 1, once per week during cycle 2, and once every 2 weeks for subsequent cycles until LM progression, intolerable toxicity, or death. Patients will undergo PK/PD assessments at the time of C1-3 doses 1 and 2 (six dosing time points) to evaluate changes iron, DFO, and ferrioxamine concentrations in the blood and CSF at each dosing cohort. PK/PD assessments will no longer be required after 5 patients in phase 1b have completed all six timepoints of completed analysis. In addition to safety and PK/PD endpoints, patients in phase 1b will also be assessed for early efficacy endpoints. |

Study Design ICMJE | Allocation: N/A Intervention Model: Single Group Assignment Intervention Model Description: This study is an open-label, non-randomized, single-center, dose escalation phase 1a study of intrathecal deferoxamine (IT-DFO) in patients with leptomeningeal metastases (LM) from solid tumor malignancies, followed by a phase 1b dose expansion cohort at the recommended phase 2 dose (RP2D) in patients with LM from non-small cell lung cancer (NSCLC). Masking: None (Open Label)Primary Purpose: Treatment |
||||||||
Condition ICMJE | Leptomeningeal Metastases | ||||||||
Intervention ICMJE | Drug: Deferoxamine (DFO)
The accelerated single-patient dose escalation will apply to dosing cohorts 1 through 4 (10mg, 30mg, 60mg, 100mg) and will convert to a 3+3 dose escalation for cohorts 5 through 9 (150mg, 210mg, 280mg, 372mg, 495mg).

Study Arms ICMJE | Experimental: Deferoxamine (DFO)
This study is an open-label, non-randomized, single-center, dose escalation phase 1a study of intrathecal deferoxamine (IT-DFO) in patients with leptomeningeal metastases (LM) from solid tumor malignancies, followed by a phase 1b dose expansion cohort at the recommended phase 2 dose (RP2D) in patients with LM from non-small cell lung cancer (NSCLC). Study objectives will include safety (1a/1b), pharmacokinetics (PK) and pharmacodynamics (PD) of IT-DFO (1a/1b), and preliminary anti-tumoral efficacy in patients with LM from NSCLC (1b).
Intervention: Drug: Deferoxamine (DFO)
