Median duration of response reaches 7.4 months with combination treatment in patients with aggressive form of disease

New results show potential of RYBREVANT^®beyond lung cancer

BARCELONA, Sept. 14, 2024 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced new data from the Phase 1b/2 OrigAMI-1 study, which showed RYBREVANT^® (amivantamab-vmjw) combined with chemotherapy (mFOLFOX6 [FOLFOX] or FOLFIRI) demonstrated promising rapid and durable antitumor activity in patients with RAS/BRAF wild-type (WT) metastatic colorectal cancer (mCRC) who have not previously received anti-epidermal growth factor receptor (EGFR) therapy. These data were presented in a mini-oral presentation at the European Society of Medical Oncology (ESMO) 2024 Congress.¹

"OrigAMI-1 is the first study to show RYBREVANT plus chemotherapy may provide clinically meaningful benefits to patients with metastatic colorectal cancer who have not received any EGFR-targeted treatments as their first or second line of therapy," said Filippo Pietrantonio, M.D., medical oncologist at Fondazione IRCCS Istituto Nazionale dei Tumori in Milan, Italy, and presenting author.* "Notably, we saw 21 percent of patients proceed to curative intent surgery, showing the promise of RYBREVANT in patients in this setting."

In the study, patients receiving RYBREVANT^® plus chemotherapy were either in their first (26 percent) or second line (74 percent) of treatment for mCRC and had not been treated with specific anti-EGFR therapies. Patients receiving FOLFOX were oxaliplatin-naïve and patients receiving FOLFIRI were irinotecan-naïve. Response was assessed by the investigator per RECIST v1.1.** Forty-three patients were treated with RYBREVANT^® along with either FOLFOX (20 patients) or FOLFIRI (23 patients). The median follow-up period was 7.3 months for RYBREVANT^® plus FOLFOX and RYBREVANT^® plus FOLFIRI.¹

Patients treated with RYBREVANT^®plus chemotherapy achieved an overall response rate (ORR) of 49 percent (95 percent confidence interval [CI], 33-65), median duration of response of 7.4 months (95 percent CI, 5.6-not estimable [NE]) and median progression-free survival of 7.5 months (95 percent CI, 7.4‒NE). Disease control was observed in 88 percent of patients (95 percent CI, 75-96). Clinically meaningful intrahepatic antitumor activity was observed among patients with liver metastases treated with RYBREVANT^® plus chemotherapy, demonstrating a significant reduction in liver tumors (ORR of 53 percent, disease control rate of 93 percent). Notably, nine (21 percent) patients were able to proceed to curative-intent surgery due to strong antitumor activity.¹

The safety profile of RYBREVANT^® plus FOLFOX/FOLFIRI was manageable and consistent with each of the individual components, without any additive toxicity. No new safety signals were observed. The most frequent treatment-emergent adverse events were neutropenia, rash, stomatitis, infusion-related reactions (IRRs) and diarrhea. All IRRs were Grade 1 or 2 and there were no Grade 3 or higher IRR events reported. Treatment-related discontinuations of RYBREVANT^®were 10 percent for RYBREVANT^® plus FOLFOX and nine percent for RYBREVANT^® plus FOLFIRI.¹

"Confirmation that RYBREVANT has activity beyond lung cancer, given its unique multi-targeted approach in inhibiting EGFR and MET, is a potentially important step forward for patients with EGFR inhibitor-naïve metastatic colorectal cancer," said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Johnson & Johnson Innovative Medicine. "Colorectal cancer is the third most common cancer globally, representing about 10 percent of all cancer cases and the second leading cause of cancer-related deaths. Our commitment to advancing cancer care drives us to evaluate every possibility to improve patient outcomes, and these findings highlight the potential of RYBREVANT to help even more patients with cancer."

Pivotal Phase 3 registration trials evaluating RYBREVANT^®-based regimens as first- and second-line treatment in colorectal cancer are planned.

About the OrigAMI-1 Study

OrigAMI-1 (NCT05379595) is an open-label Phase 1b/2 study assessing the efficacy and safety of RYBREVANT^® plus mFOLFOX6 or FOLFIRI in anti-EGFR-naïve RAS/BRAF WT mCRC. Eligible patients were WT for KRAS, NRAS or BRAF genes based on circulating tumor DNA testing. Additionally, patients were required to have no amplification of the ERBB2/HER2 gene. In the RYBREVANT^® and chemotherapy cohorts, patients were either treatment-naïve or had received at least one prior line in the metastatic setting (no EGFR inhibitor treatment). The primary endpoint of the combination cohorts was to characterize the safety and confirm the dose of RYBREVANT^® plus mFOLFOX6 or FOLFIRI. Response was assessed by the investigator per RECIST v1.1.²

About Colorectal Cancer

Colorectal cancer is the third most common cancer worldwide, accounting for approximately 10 percent of all cancer cases and is the second leading cause of cancer-related deaths worldwide.¹⁸ While it predominantly affects older individuals, recent research suggests that colorectal cancer is now being diagnosed in adults under the age of 50 at record rates.¹⁹

Left-sided colorectal cancer, which represents approximately 65 percent of cases, often has distinct characteristics that influence treatment strategies. Around half of colorectal cancer patients have mutations in the RAS genes, with KRAS being the most common mutation. While tumors with normal RAS and BRAF genes generally respond better to EGFR inhibitors, those with RAS and BRAF mutations – particularly on the left side – are associated with poorer outcomes.²⁰
