AbbVie Announces Results from Phase 2 Study Evaluating Rovalpituzumab Tesirine (Rova-T) for Third-Line Treatment of Patients with DLL3-Expressing Relapsed/Refractory Small Cell Lung Cancer
NORTH CHICAGO, Ill., March 22, 2018 /PRNewswire/ -- AbbVie (NYSE:ABBV), a global research and development-based biopharmaceutical company, today announced that after consulting with the U.S. Food and Drug Administration (FDA), it will not seek accelerated approval for Rova-T in third-line relapsed/refractory (R/R) small cell lung cancer (SCLC) based on magnitude of effect across multiple parameters in this single-arm study.
"We continue to believe Rova-T has potential for patients with small cell lung cancer and other DLL3-expressing cancers," said Mike Severino, M.D., executive vice president of research and development and chief scientific officer, AbbVie. "Although the results from the study were not what we hoped for, we look forward to receiving data from the ongoing Phase 3 studies in the first- and second-line settings and remain committed to developing Rova-T for the treatment of patients with small cell lung cancer."
In the study, the most common treatment-emergent adverse events were fatigue (38 percent), photosensitivity reaction (36 percent), pleural effusion (32 percent), edema peripheral (31 percent), decreased appetite (30 percent), nausea (26 percent), dyspnea (25 percent), thrombocytopenia (25 percent), constipation (22 percent), vomiting (17 percent), anemia (17 percent), hypoalbuminemia (16 percent), and cough (16 percent). Grade three and higher severe toxicities ≥ 5 percent were thrombocytopenia (11 percent), photosensitivity reaction (7 percent) and pleural effusion (5 percent).
About the Phase 2 TRINITY Study
TRINITY is a multicenter, open-label, single-arm, Phase 2 study of Rova-T in DLL3-expressing small cell lung cancer (SCLC) patients with relapsed/refractory (R/R) disease after receiving at least two previous regimens, including at least one platinum-based regimen. The primary objective was to investigate the efficacy of Rova-T as third-line and later treatment for R/R DLL3-expressing SCLC. Secondary objectives included assessment of safety and tolerability, pharmacokinetics, RECIST-assessed progression-free survival, duration of response and clinical benefit rate.
About Rovalpituzumab Tesirine (Rova-T)
Rova-T is an investigational antibody-drug conjugate targeting the cancer-stem cell-associated delta-like protein 3 (DLL3), which is expressed in more than 80 percent of small cell lung cancer (SCLC) patient tumors, where it is prevalent on tumor cells, including cancer stem cells, but not present in healthy tissue. Rova-T combines a targeted antibody that delivers a cytotoxic agent directly to the DLL3-expressing cancer cells while minimizing toxicity to healthy cells. Rova-T is under investigation as a third-line treatment in SCLC. The expression of DLL3 suggests Rova-T may be useful across multiple tumor types, including metastatic melanoma, glioblastoma multiforme and some prostate, pancreatic and colorectal cancers.
Rova-T is an investigational compound and its efficacy and safety have not been established by the FDA or any other health authority.
