This drug was developed by ImClone Systems Inc. It was isolated from a native phage display library from Dyax. On 21 April 2014, the US Food and Drug Administration (FDA) approved ramucirumab as a single-agent treatment for advanced gastric cancer or gastro-esophageal junction (GEJ) adenocarcinoma after prior treatment with fluoropyrimidine- or platinum-containing chemotherapy. The approval was based on the results of the REGARD trial, a phase III, international, randomized, double-blind, placebo-controlled study, that evaluated the safety and efficacy of ramucirumab combinated with best supportive care versus placebo. Ramucirumab has also been studied in combination with paclitaxel (a type of chemotherapy) and received additional FDA approval on 5 November 2014 as a treatment for people with advanced gastric cancer or GEJ adenocarcinoma after prior treatment with fluoropyrimidine- or platinum-based chemotherapy. The approval was based on the results of the RAINBOW trial, that compared ramucirumab plus paclitaxel or paclitaxel alone. On 12 December 2014, the FDA approved ramucirumab in combination with docetaxel for treatment of metastatic non-small-cell lung carcinoma (NSCLC) with disease progression during or after first-line platinum-containing chemotherapy. The approval was based on REVEL trial. On 24 April 2015, ramucirumab was approved by FDA for the treatment of patients with metastatic colorectal cancer (mCRC) with disease progression on or after prior therapy with bevacizumab, oxaliplatin, and fluoropyrimidine. The approval was based on the results of the RAISE trial, a phase III study, which compared ramucirumab plus irinotecan, folinic acid, and 5-fluorouracil (FOLFIRI) to FOLFIRI alone. On 10 May 2019, ramucirumab was approved by FDA as a single agent treatment for hepatocellular carcinoma (HCC) in patients who have an alpha fetoprotein (AFP) of > 400 ng/mL and have been previously treated with sorafenib. The approval was based on REACH-2 (NCT02435433), a multinational, randomized, double-blind, placebo-controlled, multicenter study in patients with advanced HCC with AFP > 400 ng/mL who had disease progression on or after sorafenib or who were intolerant. The estimated median overall survival (OS) was 8.5 months (7.0-10.6 months) for patients receiving ramucirumab and 7.3 months (5.4-9.1 months) for those receiving placebo. Under the European approval, NSCLC therapy with ramucirumab is contraindicated when there is tumour cavitation, or if major vessels are involved. The most common adverse effects in a study investigating ramucirumab monotherapy were diarrhoea (14% of patients, as compared to 9% under placebo), hyponatraemia (low blood sodium levels; 6% versus 2%), headache (9% versus 3%), and high blood pressure (16% versus 8%). In studies, no interactions were observed with paclitaxel, docetaxel or irinotecan.
