Summary
Patients may be included in the study only if they meet all of the following criteria:
Age > or = 21 years.
Histological or cytological diagnosis of malignant advanced solid tumors refractory to standard therapy or for which no suitable effective standard therapy exists.
o Patients who fit above criteria will be pre-screened for presence of 1q21.3 amplification using a plasma assay based on digital PCR. Patients with tumors that exhibit 1q21.3amplification will be enrolled. Positive 1q21.3 amplification is defined as more than 3 standard deviations above the mean comparing the averaged copy number ratio of 3 genes (TUFT1, S100A8 and S100A7) relative to the reference gene RPP30 measure in sample (13).
ECOG 0-2Has measureable or evaluable disease based on RECIST 1.1 criteria Estimated life expectancy of at least 12 weeks. Has documented progressive disease from last line of therapy Has recovered from acute toxicities from prior anti-cancer therapies
Adequate organ function including the following:
Bone marrow:
Absolute neutrophil (segmented and bands) count (ANC) > or = 1.5 x 109/LPlatelets > or = 100 x 109/L Hemoglobin > or = 8 x 109/L
Hepatic:
Bilirubin < or = 1.5 x upper limit of normal (ULN),ALT or AST < or = 2.5x ULN, (or < or = 5 X with liver metastases)
Renal:
Creatinine < or = 1.5x ULNSigned informed consent from patient Able to comply with study-related procedures.
Prior therapy (patients enrolled in phase Ib may be enrolled if they fulfil prior therapy criteria for either Cohort A or Cohort B)
Cohort A only: Has received at least 2 lines of systemic therapy (endocrine or chemotherapy) in the palliative setting. Chemotherapy in an adjuvant setting for which patients relapsed within 6 months of completion can be considered as line(s) of palliative therapy.Cohort B only: Any number of prior lines of palliative chemotherapy.
