What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Establish the maximal tolerated dose of cabozantinib in combination with Lu-177 dotatae at a standard dose of 7.4 GBg in four 8-week cycles followed by continuation of cabozantinib.
Time Frame: Up to 2 years
|
The phase I objective of this study is to establish the maximal tolerated dose (MTD) of cabozantinib in 20 mg, 40 mg and 60 mg dose escalation cohorts in combination with Lu-177 dotatate at a standard dose of 7.4 GBq in four (4) 8-week cycles followed by continuation cabozantinib.
Due to overlapping toxicities of cabozantinib and Lu-177 dotatate and to allow more incremental dose escalation of cabozantinib, alternating day dosing of 40mg/20mg and 60mg/40mg cohorts are incorporated into the schema.
This is expected to reduce the risk of overlapping toxicities while still achieving radio-sensitizing anti-angiogenic, multi-targeted therapy in combination with the beta-emitting radiation from lutetium 177 synergistic due to the prolonged half-life of cabozantinib.

Up to 2 years

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Establish objective response rate as measured by RECIST 1.1
Time Frame: Up to 2 years post study completion
|
The secondary outcome measure is to establish the objective response rate (ORR) as measured by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
Imaging is done every 16 weeks and/or re-staging through study completion up to 2 years.
A minimum observed overall response rate (ORR) of ≥ 25% in the PRRT-naïve cohort, as measured by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 in the treatment population would justify further randomized efficacy studies.

Up to 2 years post study completion
