Primary Objective:
- To assess the efficacy of CTX-009 in combination with paclitaxel vs. paclitaxel alone in patients with biliary tract cancers (BTC) who have received one systemic therapy for advanced disease, as measured by Overall Response Rate (ORR) assessed by an Independent Central Radiology (ICR) review.
Secondary Objectives:
- To assess the efficacy of CTX-009 in combination with paclitaxel vs. paclitaxel alone in patients with BTC as measured by Disease Control Rate (DCR), assessed by an ICR review.
- To assess the efficacy of CTX-009 in combination with paclitaxel vs. paclitaxel alone in patients with BTC as measured by Duration of Response (DOR), assessed by an ICR review.
- To assess the efficacy of CTX-009 in combination with paclitaxel vs. paclitaxel alone in patients with BTC as measured by Progression Free Survival (PFS).
- To assess the efficacy of CTX-009 in combination with paclitaxel vs. paclitaxel alone in patients with BTC as measured by Overall Survival (OS).
- To evaluate the safety profile of CTX-009 in combination with paclitaxel.
- To assess the Quality of Life (QoL), as measured using the EORTC QLQ-C30 and BIL21, in patients with BTC treated with CTX-009 in combination with paclitaxel vs. paclitaxel alone.

Female patients who are women of childbearing potential (WCBP) must have a negative pregnancy test (serum-hCG or urine-hCG performed at the Investigator's discretion) within 14 days of randomization 10. Female patients must be surgically sterile (or have a monogamous partner who is surgically sterile) or be at least 2 years postmenopausal or commit to use 2 acceptable forms of birth control (defined as the use of an intrauterine device (IUD), a barrier method with spermicide, condoms, or any form of hormonal contraceptives) or abstinence for the duration of the study and for 6 months following the last dose of study treatment. Male patients must be sterile (biologically or surgically) or commit to the use of a reliable method of birth control (condoms with spermicide) for the duration of the study and for 6 months following the last dose of study treatment. 11. Signed and dated Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved Informed Consent Form (ICF) before any protocol-directed screening procedures are performed EXCLUSION CRITERIA 1. Patients who are eligible to be treated with a molecularly targeted therapy on a labelled regimen after receiving first-line chemotherapy. Patients who received a molecularly targeted therapy as part of their first line treatment may be eligible, as determined by the Sponsor Medical Monitor. 2. From the time point of screening, 1. Less than 4 weeks have elapsed since patients had a surgery or major procedure 2. Less than 2 weeks have elapsed from the last treatment date since patients had any radiation therapy 3. Patients with percutaneous transhepatic biliary drains (PTBD) 4. Prior to the initial treatment of study drug, 1. Less than 2 weeks have elapsed since patients had chemotherapy or hormone therapy 2.
