Heroine01: A Phase I/II Multicenter, Open-Label Study of Lu-177-αvβ3-IAC, for the Treatment of Angiogenic Breast Cancer Patients.
Study Details
Study Description
Brief Summary
This study is a Phase I/II clinical evaluation of a new investigational agent, Lutetium-177-PEG-αvβ3-IAC (HurlutinTM Lu-177) to treat patients with unresectable angiogenic breast cancer who have previously been treated with at least one prior line of therapy.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1/Phase 2 |
Detailed Description
This is a prospective, Phase I/II multi-center, interventional open-label study in a total of up to 100 subjects with angiogenic breast cancer. Phase I is to assess the safety and adequacy of a dose of HurlutinTM Lu-177 for up to two cycles, at 6-8-week intervals. It will include a dose expansion cohort of up to 20 patients. Phase II is to demonstrate the safety, dose adequacy, anti-tumor activity and efficacy of tumor targeted therapy using Lutetium-177-PEG-αvβ3-IAC , as a second- or third-line treatment to extend survival and improve the quality of life of patients with angiogenic breast cancer.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Arm 1 Single Arm study Lu-177-αvβ3-IAC (intracutaneous) Dosage and Dose Escalation Frequency: Cohort 1: 75 mCi x 3 (maximum cumulative administered activity, 225mCi) + 100 μgr IAC Cohort 2: 150 mCi x 3 (maximum cumulative administered activity, 450mCi) + 100 μgr IAC Cohort 3: 200 mCi x 3 (maximum cumulative administered activity, 600mCi) + 100 μgr IAC Three cycles each 8 weeks apart. |
Drug: Lutetium-177-PEG-αvβ3-IAC
Study participants be administered therapeutic doses of Lutetium-177-PEG-αvβ3-IAC up to three treatments spaced 6-8 weeks apart and a CT scan immediately after. A Ga-68-PEG-αvβ3-IAC PET/CT scan will be performed four weeks before and four weeks after the initial dose of the Lutetium-177-PEG-αvβ3-IAC.

Outcome Measures
Primary Outcome Measures
- Specific Aim 1 [6 months]
To determine the safety and tolerability of fractionated administrations of 2 cycles of Lu-177-αvβ3-IAC administered with 4 weeks between cycles in patients with high-risk Angiogenic Breast Cancer who have progressed on, or do not tolerate, best standard-of-care treatment. Measurements used to assess the safety, tolerability and side-effects profile will include adverse events of any grade, grade 3 and 4 adverse events, withdrawals due to adverse events and dose reductions due to adverse events. National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE v.5.0) will be used to evaluate AE grade.
- Specific Aim 2 [6 months]
To determine the pharmacokinetics (PK) of Lu-177-αvβ3-IAC. The area under the Time vs. Concentration curve for Ga-68-αvβ3-IAC from injection to 72 h
- Specific Aim 3 [6 months]
To determine the whole-body biodistribution of Lu-177-αvβ3-IAC. Percent injected dose per gram of tissue (%ID)/gm of Lu-177-αvβ3-IAC.
- Specific Aim 4 [6 months]
To determine the radiation dosimetry of Lu-177-αvβ3-IAC.Time points will be 0 and 120, 30 and 150, 60 and 180, or 90 and 210 min after injection.Time integrals of activity will be entered into the (Organ Level INternal Dose Assessment/ EXponential Modeling) OLINDA/EXM software.
- Specific Aims 5 [6 months]
To determine optimum cumulative fractionated administered dose. Increase dose range if a DLT (Dose Limiting Toxicity) develops or they do not have a T/B ratio >1.
Secondary Outcome Measures
- Specific Aim 1 [6-12 Months]
To determine the Objective Response Rate (ORR) of fractionated administration of Lu-177-αvβ3-IAC.Percentage of subjects still alive. Percentage of subjects who achieved a best overall response of Complete Response [CR] or Partial Response [PR] according to RECIST 5.0 Criteria.
