Last Update Posted : April 20, 2021
Patients with moderate to high risk primary breast cancer (Stage II with more than 4 lymph nodes involved with cancer) III or Stage IV (without evidence of disease) will take tetrathiomolybdate (TM) pills for two years.
The objectives of the study are to:
- Assess the safety and tolerability of tetrathiomolybdate in patients with breast cancer at high risk of tumor recurrence.
- Observe the disease-free survival of patients in this trial.
- Conduct background scientific experiments on tumor tissue and blood of patients in this study
|Condition or disease||Intervention/treatment||Phase|
|Breast Cancer||Drug: Tetrathiomolybdate||Phase 2|
Patients with moderate to high risk primary breast cancer -Stage III, Triple negative (T= 4 cm N0, any N+), Stage IV (without evidence of disease) will take tetrathiomolydbate (TM) pills for two years.
Extension study 1 - If patients are shown to be copper depleted, they are given the option to continue to receive TM for an additional 2 years.
Extension study 2 - Open to patients who are stage 4 NED, 10 involved lymph nodes or triple negative molecular subtype and candidates will continue for months 49-72.
Extension study 3 - Open to patients who are stage 4 NED receiving a benefit from TM. These subjects can continue receiving TM for 73-96 months.
Extension study 4 - Open to patients who are stage 4 NED receiving a benefit from TM. These subject can continue receiving TM for 97-120 months.

|Official Title:||A Phase II Study of Tetrathiomolybdate (TM) in Patients With Breast Cancer at Moderate to High Risk of Recurrence|
|Study Start Date :||December 2003|
|Estimated Primary Completion Date :||June 2022|
|Estimated Study Completion Date :||June 2022|
Experimental: Tetrathiomolybdate (TM)
Induction period - TM 40 mg is administered three x per day with meals and TM 60 mg at bedtime for a total of 4 doses (180 mg) per day.
Maintenance Period - Total TM dose per day will be in 20 mg increments to tailor the therapy to individualized patient needs to maintain the Cp level at 5-17mg/dL. Thus all dose modifications will be dependent on individual patient Cp levels. TM 40 mg p.o. BID with meals and TM 20 mg at bedtime. Subjects who have no evidence of disease (NED) and are receiving a benefit of TM can continue taking the drug for up to 120 months.
Induction with Tetrathiomolybdate (TM) Tetrathiomolybdate 40 mg. p.o. TID with meals and tetrathiomolybdate 60 mg at bedtime for a total of 4 doses (180 mg) per day.
Induction goal Total tetrathiomolybdate dose per day = 180 mg until serum ceruloplasmin (Cp) level decreases to 5-15mg/dL.
When target Cp window is reached, then the maintenance phase begins.
Maintenance with Tetrathiomolybdate Total tetrathiomolybdate dose per day = 100 mg
Tetrathiomolybdate 40 mg p.o. BID with meals and tetrathiomolybdate 20 mg at bedtime.
