Trial Outcomes & Findings for Continuous 24h Intravenous Infusion of Mithramycin, an Inhibitor of Cancer Stem Cell Signaling, in People With Primary Thoracic Malignancies or Carcinomas, Sarcomas or Germ Cell Neoplasms With Pleuropulmonary Metastases (NCT NCT02859415)

NCT ID: NCT02859415

Last Updated: 2022-04-05

Results Overview

MTD is defined as the number of participants experiencing a dose-limiting toxicity (DLT). A DLT is defined as Grade 4 or greater anemia or neutropenia exceeding 5 days duration, thrombocytopenia requiring transfusion, or Grade 3 or greater nonhematologic toxicity possibly, probably, or definitely related to the investigational therapy excluding alopecia during Cycle 1 of therapy.

PRIMARY outcome

Timeframe: At the end of first 14 day cycle at each dose level

MTD is defined as the number of participants experiencing a dose-limiting toxicity (DLT). A DLT is defined as Grade 4 or greater anemia or neutropenia exceeding 5 days duration, thrombocytopenia requiring transfusion, or Grade 3 or greater nonhematologic toxicity possibly, probably, or definitely related to the investigational therapy excluding alopecia during Cycle 1 of therapy.

Phase I Dose Level -1 Mithramycin 60 mcg/kg Followed by Mithramycin 30 mcg/kg
Phase I Dose Level -1 Mithramycin 60 mcg/kg followed by Mithramycin 30 mcg/kg Mithramycin: Phase 1: 24 hour intravenous infusion of mithramycin given once every 14 days at escalating doses.
Maximum Tolerated Dose (MTD)
NA mcg/kg
The MTD was not found because we did not have enough participant participation.

PRIMARY outcome

Timeframe: every 8 weeks until at disease progression, approximately 3.5 months

Population: One participant in the first group only received one dose, thus was not evaluable.

Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). Complete response is disappearance of all target lesions. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

Population: No data was collected thus this outcome measure was not done.

Studies on tumor tissue obtained during baseline /previous biopsy (if available), Cycle 1 Day 4(+/- 3 days), and possible treatment evaluation following Course 1. Plasma and blood will also be collected.

Here is the number of participants with serious and/or non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
