Phase I/II AZD8931/Paclitaxel in Treatment of Advanced Solid Tumours (Phase I) and Advanced Breast Cancer (Phase II)

DLT is an AE or laboratory abnormality related to AZD8931, starting during the DLT evaluation period and meeting any of the following criteria (further detail in protocol): Symptomatic ocular surface lesion; CTCAE grade 4 haematological AE; CTCAE grade ≥3 of febrile neutropenia / neutropenia / thrombocytopenia / hyperkalaemia / hyperglycaemia / hypotension / urological toxicity / ILD / pneumonitis; QTcF interval > 500 msec, two ECGs ≥ 30 minutes apart; Symptomatic congestive cardiac failure and a drop in LVEF; Decrease in LVEF of ≥20% to below the LLN; CS rash remaining CTCAE grade ≥3 for ≥5 days despite optimal treatment; CTCAE grade ≥3 nausea, vomiting or diarrhoea, despite optimal therapy; Other CTCAE grade ≥3 toxicity which, in the opinion of the investigator, is CS and related to AZD8931; Delay to the administration of paclitaxel on D1 of Cycle 2 by ≥7 days. Patients could have more than one DLT.

Time from the date of randomization until the date of objective disease progression (as per RECIST 1.1) or the date of death (by any cause in the absence of progression)

The number of subjects with at least one visit response of CR or PR (Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Progressive disease (PD), A ≥ 20% increase in the sum of diameters of target lesions and an absolute increase of ≥ 5mm; Stable disease (SD), Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD; Not Evaluable (NE), All target lesion measurements are missing or >1/3 target lesion measurements are missing and sum of diameters of non-missing target lesions does not qualify for PD; Not applicable (NA), No target lesions are recorded at baseline))

The time from the date of randomization until the date of death due to any cause.
