* For phase 1b, patients for whom the backbone chemotherapy (dose and schedule) can be considered as a standard therapeutic regime for their cancer.
* Have measurable disease or non-measurable disease, defined according to RECIST Version 1.1. Patients with skin only metastases are eligible, if the appropriate photography documentation (including measurement) of the skin metastases is provided.
* Adequate organ and bone marrow function
* Willingness, if not postmenopausal or surgically sterile, to abstain from sexual intercourse or employ an effective barrier method of contraception during the study drug administration and for a period of 6 months following the last dose.
* Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to start of treatment. Women of childbearing potential or men with partners of childbearing potential must use effective birth control measures during treatment, and at least 6 months after the last dose of study treatment. If a woman becomes pregnant or suspects she is pregnant while participating in this study, she must agree to inform her treating physician immediately. Sexually active men must agree to use a medically acceptable form of birth control during treatment and at least 6 months after the last dose. If a female partner becomes pregnant during course of study the treating physician should be informed immediately.

Exclusion criteria:

* Systemic anticancer therapy within 14 days before the first dose of study drug.
* Known allergy or hypersensitivity to components of the iniparib, gemcitabine, paclitaxel, PLD,or carboplatin formulation.
* Not recovered to Grade ≤1 from adverse events (AE), per NCI-CTCAE Version 4.03 or to within 10% of pre-treatment baseline values, due to investigational drugs, radiation, or other medications administered more than 30 days before enrollment in this study. Alopecia at screening is not exclusionary.
* Prior radical (curative) radiation therapy for treatment of cancer ≥25% of the bone marrow (1). Prior radiation to the whole pelvis is not allowed. Prior radical radiotherapy must be completed at least 4 weeks before study entry.
* Patients who have received palliative radiation therapy for symptomatic metastases must have completed treatment ≥14 days prior to initiation of study treatment.
* Active brain metastases. Patients with treated brain metastases are eligible, if 1. Radiation therapy was completed at least 2 weeks prior to study treatment; 2. Follow-up scan shows no disease progression; and 3. Patient does not require steroids. Screening for brain metastases is not required if the patient is asymptomatic.
* Clinically significant cardiac disease including congestive heart failure (New York Heart Association Class III or IV), including pre-existing ventricular arrhythmia or conduction abnormality requiring medication, or cardiomyopathy or history of a myocardial infarction within the last 6 months
* Other major medical condition (eg, uncontrolled pulmonary, renal, or hepatic dysfunction, uncontrolled infection) which the Investigator feels might compromise the patient's effective and safe participation in the trial.
* Pregnant or breastfeeding
* Have known positive test results in human immunodeficiency virus (HIV), hepatitis B surface antigen (HBSAg), or Hepatitis C Antibodies (HCAb). Testing is not required unless circumstances warrant confirmation.
* Patients with acute or chronic leukemia or with any other disease likely to have a significant bone marrow infiltration (screening not required).
* Prior treatment with gemcitabine, carboplatin, paclitaxel, or Pegylated liposomal doxorubicin.
