ModraDoc006/r in Patients With Breast Cancer
Study Details
Study Description
Brief Summary
This is a multicenter phase IIa study to evaluate the efficacy and tolerability of ModraDoc006 in combination with ritonavir (denoted ModraDoc006/r) in patients with recurrent or metastatic HER-2 negative breast cancer, that are suitable for treatment with a taxane as 1st-3rd line of therapy.

Detailed Description
This is a phase IIa, multicentre, two-stage, single-arm, clinical study with the primary objective is to determine the efficacy of ModraDoc006 in combination with ritonavir (denoted ModraDoc006/r) in patients with recurrent or metastatic HER-2 negative breast cancer, as measured by RECIST v1.1 criteria of objective response rate (ORR). To this aim, a Simon two-stage minimax design will be used, in which 14 evaluable patients will be treated in the first stage (Stage A). If 0 or ≥ 2 objective responses at week 8 (with confirmation at week 12) are observed in Stage A, no further patients will be enrolled. If 1 objective response is observed, an additional 10 patients with recurrent or metastatic HER-2 negative breast cancer will be included in the second stage (Stage B).
All patients will be treated with ModraDoc006/r, given as oral tablets twice daily once weekly (BIDW).
Patients will be radiologically assessed at week 8 and 12 by CT scan (or MRI if CT is contraindicated), and may continue to receive study medication with ongoing radiological scans every 6 weeks until disease progression (according to RECIST v1.1), unacceptable toxicity, or discontinuation for any other reason.
Furthermore, the safety and tolerability of ModraDoc006/r in the target population will be assessed. Additionally, as metastatic breast cancer may occur at older age, often coinciding with other non-malignant diseases and co-medications, this protocol investigates whether ModraDoc006/r can be applied safely in these (frail) patients.

Outcome Measures
Primary Outcome Measures
- The objective response rate (ORR) [From baseline through study completion, an average of 1 year]
Evaluation of objective response rate that will be observed as measured by RECIST v1.1 criteria, in patients with recurrent or metastatic HER2 negative breast cancer after treatment with ModraDoc006/r
Secondary Outcome Measures
- The number of CTCAE v.4.03 toxicities during treatment with ModraDoc006/r [Evaluation of toxicities during the complete study treatment until 28 days after the last intake, using the CTCAEv4.03 grading system]
The hematological and non-hematological toxicity profile of ModraDoc006/r will be assessed by clinical and lab evaluation and evaluated according to CTCAE v.4.03
- The activity data on progression-free survival (PFS) of ModraDoc006/r [From baseline through study completion, an average of 1 year]
Evaluation of progression free interval (PFS) that will be observed as measured by RECIST v1.1 criteria, in patients with recurrent or metastatic HER2 negative breast cancer during and after treatment with ModraDoc006/r
Other Outcome Measures
- The number of CTCAE v.4.03 toxicities during treatment with ModraDoc006/r in a population of frail patients [Evaluation of toxicities during the complete study treatment until 28 days after the last intake, using the CTCAEv4.03 grading system]
The hematological and non-hematological toxicity profile of ModraDoc006/r in frail patients will be assessed by clinical and lab evaluation and evaluated according to CTCAE v.4.03
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Able to give written informed consent and to comply with the protocol
-
Histologically- or cytologically confirmed diagnosis of recurrent or metastatic HER-2 negative breast cancer

Patients who are eligible to receive a taxane as monotherapy as 1st-3rd line of therapy for recurrent or metastatic breast cancer. A maximum of two previous lines of chemotherapy is allowed (including experimental i.e. non-registered chemotherapy alone or in combination). Re-treatment with one of the same drugs after treatment interruption for reasons of patient preference and/or progression of disease counts as a new treatment
-
WHO performance status of 0, 1 or 2 (Appendix II)
-
Estimated life expectancy of at least 12 weeks
-
Resolution of toxicity of prior therapy to < grade 2 (except for alopecia and transaminases in case of liver metastases) as defined by CTCAE v5.0 (Appendix III)
-
Evidence of measurable disease present at baseline as defined by RECIST v1.1
-
Able and willing to swallow oral medication
-
Able and willing to undergo radiologic scans (CT scan, or MRI if CT is contraindicated)
