Phase 1 non randomised open label dose finding trial using 3+3 design.Single armmonotherapy |
ORR, CR, PR measured using RECIST and CT or MRI scan. AEs measured using CTCAE |

Very small cohort. No written consent found. First in human trial. MTD found at 400 BiD |

Comparator arm on lower dose (100mg) = MTD is most effective. |

Compares results between BRCAm or BRCAwt. Very small cohort. Heavily treated - 70% > 3 prior chemotherapy,TNBC = large heterogeneity among patients.3 patients data not confirmed. |

No written consent found. AEs reduced over time suggesting carryover from prior chemotherapy study. Mistake found in results text. Patients on therapy for up to 3.5 years. |

Very heavily pre-treated (average 4.6 prior therapies). No written consent found. 47% SD is a very good response rate given the heavy pre-treatment of these patients. |

Not truly randomised as physicians choice was limited - and no placebo arm. Least pre-treated cohort with some patients only one prior treatment. Also measured QoL and PFS2. End point PFS was reached. |
