Study Endpoints

Primary Endpoints

Safety and tolerability of OMP-54F28 in combination with sorafenib in patients with hepatocellular cancer
Subjects will be treated and observed for DLT through the end of the first cycle (from Day 0 - 21)

The maximum tolerated dose (MTD) will be determined in patients treated with OMP-54F28 in combination with sorafenib in patients with hepatocellular cancer

Safety and tolerability of OMP-54F28 in combination with paclitaxel and carboplatin in patients with recurrent platinum-sensitive ovarian cancer
Subjects will be treated and observed for DLT through the end of the first cycle (from Day 0 - 21)

The maximum tolerated dose (MTD) will be determined in patients treated with OMP-54F28/paclitaxel/carboplatin (from Day 0 - 21)

Safety and tolerability of OMP-54F28 in combination with nab-paclitaxel and gemcitabine in patients with previously untreated Stage IV pancreatic cancer
Subjects will be treated and observed for DLT through the end of the first cycle (from Day 0 - 28)

The maximum tolerated dose (MTD) will be determined in patients treated with gemcitabine in combination with weekly nab-paclitaxel (from Day 0 - 28)

• To determine the safety of OMP-54F28 in subjects with previously treated solid tumors
Subjects will be assessed for dose limiting toxicities from Days 0-28. Adverse events will be reported through 30 days after the last dose.

Frequently asked questions about OMP-54F28, Nab-Paclitaxel and Gemcitabine

What is OMP-54F28, Nab-Paclitaxel and Gemcitabine?

OMP-54F28, Nab-Paclitaxel and Gemcitabine is a Phase 1 combination regimen studied in patients with previously untreated Stage IV pancreatic cancer. It pairs the investigational agent OMP-54F28 with two chemotherapy drugs, nab-paclitaxel and gemcitabine. The combination was evaluated in a dose escalation study conducted in the United States.

Who is developing OMP-54F28, Nab-Paclitaxel and Gemcitabine?

Mereo BioPharma Group plc, which trades under the ticker MREO, is the developer associated with OMP-54F28, Nab-Paclitaxel and Gemcitabine. The company's pipeline covers the OMP-54F28 program, including this pancreatic cancer combination regimen and the other OMP-54F28 combination studies in ovarian cancer, hepatocellular cancer, and solid tumors.

What phase is OMP-54F28, Nab-Paclitaxel and Gemcitabine in?

OMP-54F28, Nab-Paclitaxel and Gemcitabine is in Phase 1 development. The pancreatic cancer combination was studied in a single Phase 1 dose escalation trial that has completed. No Phase 2 or later studies of this specific regimen are listed, so it remains an investigational combination rather than an approved treatment.

What clinical trial studied OMP-54F28, Nab-Paclitaxel and Gemcitabine?

The regimen was studied in NCT02050178, a Phase 1 dose escalation trial titled Dose Escalation Study of OMP-54F28 in Combination With Nab-Paclitaxel and Gemcitabine in Patients With Previously Untreated Stage IV Pancreatic Cancer. The trial enrolled 26 patients, was conducted in the United States, and has completed.

What cancers has OMP-54F28, Nab-Paclitaxel and Gemcitabine been studied in?

OMP-54F28, Nab-Paclitaxel and Gemcitabine has been studied in previously untreated Stage IV pancreatic cancer. The broader OMP-54F28 program also includes combination studies in ovarian cancer, hepatocellular cancer, and solid tumors, but the nab-paclitaxel and gemcitabine regimen itself was evaluated specifically in the pancreatic cancer setting.
