First results from late-breaking Phase 3 PALOMA-3 study show five-fold reduction in infusion-related reactions with five-minute subcutaneous amivantamab administration

• New formulation showed non-inferiority to intravenous administration in fourth positive Phase 3 study in RYBREVANT^® clinical program
• Longer overall survival, progression-free survival and duration of response shown with subcutaneous amivantamab; featured in Best of ASCO 2024
• RYBREVANT^® marketing application submitted to European Medicines Agency based on PALOMA-3 study

CHICAGO, May 31, 2024 /PRNewswire/ -- Johnson & Johnson announced today first data from the Phase 3 PALOMA-3 study evaluating subcutaneous (SC) amivantamab combined with lazertinib in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletion (ex19del) or L858R mutations. Study results showed non-inferior efficacy and pharmacokinetics for SC amivantamab combined with lazertinib compared to intravenous (IV) administration, the currently approved formulation of RYBREVANT^® (amivantamab-vmjw). Administration time for SC amivantamab was reduced to approximately five minutes from five hours (across two days) and showed a five-fold reduction in infusion-related reactions (IRRs). These late-breaking results, which are the Company’s fourth positive Phase 3 readout for the RYBREVANT^® clinical program, were featured as an oral presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract #LBA8505).¹ Data were also selected for the Best of ASCO 2024 Meetings, highlighting the cutting-edge science and leading research in oncology from Johnson & Johnson.

“The PALOMA-3 data show that subcutaneous amivantamab offers shorter infusion times and lower rates of infusion-related reactions and venous thromboembolism with pharmacokinetics and efficacy comparable to the current IV administration,” said Dr. Natasha B. Leighl*, medical oncologist at the Princess Margaret Cancer Centre in Toronto, Canada, and the presenting author. “I look forward to seeing how these findings can make a meaningful difference in clinical practice by potentially improving the treatment experience for patients with EGFR-mutated non-small cell lung cancer.”

Results showed SC amivantamab was non-inferior to IV amivantamab, meeting both co-primary pharmacokinetic (PK) efficacy endpoints as measured by amivantamab levels in the blood (C_trough and area under the serum concentration time curve from day 1 to 15).¹

At a median follow-up of seven months, the overall response rate was 30 percent (95 percent confidence interval [CI], 24–37) in the subcutaneous arm and 33 percent (95 percent CI, 26–39) for IV (relative risk, 0.92; 95 percent CI, 0.70-1.23; P=0.001), meeting the noninferiority criteria. SC amivantamab also demonstrated longer duration of response (DoR), progression-free survival (PFS) and significant improvement in overall survival (OS) compared to IV administration during this time. Specifically, median DoR was numerically longer for SC amivantamab combined with lazertinib compared to IV (median, 11.2 vs 8.3 months among confirmed responders) as was PFS (median, 6.1 vs 4.3 months; hazard ratio [HR], 0.84; 95 percent CI, 0.64–1.10; P=0.20). A pre-specified exploratory endpoint showed patients treated with SC amivantamab had significantly longer OS compared with IV (HR, 0.62; 95 percent CI, 0.42–0.92; nominal P=0.02). At 12 months, 65 percent of patients who received SC amivantamab combined with lazertinib were alive compared with 51 percent of those treated with the IV regimen. It is theorized that the efficacy seen with SC amivantamab may be linked to SC absorption via the lymphatic system, potentially enhancing immune-mediated activity.¹

Of particular note, administration time was substantially shorter for SC amivantamab (median less than approximately five minutes) compared to IV administration (up to five hours), with significantly more patients reporting convenience with the SC administration (85 percent with SC amivantamab vs 35 percent with IV administration at end of treatment; P<0.001).¹

The overall safety profile of SC amivantamab is consistent with the known profile of IV administration. The most common all-grade adverse events (≥ 20 percent) for SC amivantamab compared to IV were paronychia (54 percent vs 51 percent), hypoalbuminemia (47 percent vs 37 percent) and rash (46 percent vs 43 percent), respectively. No Grade 4 or 5 IRRs were reported. The rate of IRRs for patients treated with SC amivantamab combined with lazertinib was shown to be approximately five-fold lower than that observed with the IV formulation (13 percent vs 66 percent, respectively). Prophylactic anticoagulation was used in most patients in the study and was found to be safe and effective in reducing the rate of venous thromboembolic events (VTE). Patients receiving prophylactic anticoagulation had lower rates of VTE (10 percent) than those without prophylaxis (21 percent). Furthermore, VTE incidence was lower in the SC arm compared to the IV arm (9 percent vs 14 percent, respectively) regardless of anticoagulation use. Severe bleeding risk was low and similar among patients receiving anticoagulants in the SC (2 percent) and IV (1 percent) arms.¹

“We are always exploring innovative approaches to meet the urgent needs of patients living with EGFR-mutated non-small cell lung cancer and these compelling findings reinforce the potential for a new route of administration for amivantamab,” said Yusri Elsayed, M.D., M.H.Sc., Ph.D., Global Therapeutic Area Head, Oncology, Johnson & Johnson Innovative Medicine. “We look forward to pursuing regulatory submissions for this formulation, as we advance our ambition to transform the first-line treatment of EGFR-mutated NSCLC.”

Today, Janssen-Cilag International NV, a Johnson & Johnson company, announced the submission of an application for the extension of the RYBREVANT^® marketing authorization (line extension) to the European Medicines Agency (EMA) seeking approval of SC amivantamab in combination with lazertinib for the first-line treatment of adult patients with locally advanced or metastatic NSCLC with EGFR ex19del or L858R mutations and as monotherapy in adult patients with advanced NSCLC with activating EGFR exon 20 insertion mutations after failure of platinum-based therapy based on the PALOMA-3 data. Johnson & Johnson will submit regulatory applications seeking the approval of SC amivantamab in other markets, including the United States.

About PALOMA-3

PALOMA-3 (NCT05388669), which enrolled 418 patients, is a randomized, open-label Phase 3 study evaluating the pharmacokinetics (PK), efficacy and safety of subcutaneous amivantamab (administered via manual injection) combined with lazertinib compared to IV amivantamab and lazertinib in patients with EGFR-mutated advanced or metastatic NSCLC after progression on osimertinib and chemotherapy. The co-primary PK endpoints of the study were trough concentration (C_trough on Cycle [C] 2 Day [D] 1 or C4D1) and C2 area under the curve (AUCD1-D15). Key secondary endpoints were objective response rate and progression-free survival. Overall survival was a predefined exploratory endpoint. Prophylactic anticoagulation was recommended for the first four months of treatment.²

About Non-Small Cell Lung Cancer

Worldwide, lung cancer is one of the most common cancers, with NSCLC making up 80 to 85 percent of all lung cancer cases.^{15, 16} The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.¹⁷ Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase controlling cell growth and division.¹⁸ EGFR mutations are present in 10 to 15 percent of Western patients with NSCLC with adenocarcinoma histology and occur in 40 to 50 percent of Asian patients.^{17,18,19,20,21,22} EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.²³ The five-year survival rate for all people with advanced NSCLC and EGFR mutations treated with EGFR tyrosine kinase inhibitors (TKIs) is less than 20 percent.^24,25 EGFR exon 20 insertion mutations are the third most prevalent activating EGFR mutation.²⁶ Patients with EGFR exon 20 insertion mutations have a real-world five-year overall survival (OS) of eight percent in the frontline setting, which is worse than patients with EGFR ex19del or L858R mutations, who have a real-world five-year OS of 19 percent.²⁷
