RARITAN, N.J., March 27, 2025 – Results from an interim analysis of the open-label Phase 2 COCOON study revealed a simple, readily available preventative regimen (the COCOON regimen) reduced moderate-to-severe dermatologic reactions (including skin and nail reactions Grade 2 or higher) by 50 percent in patients receiving first-line treatment with RYBREVANT® (amivantamab-vmjw) and LAZCLUZE™ (lazertinib) versus standard dermatologic management. These data were presented as a mini oral presentation at the 2025 European Lung Cancer Congress (ELCC) (Abstract #10MO).1
“RYBREVANT plus LAZCLUZE helps patients live longer, as seen in the MARIPOSA study, and now we have a way to make the treatment more manageable,” said Dr. Pascale Tomasini*, M.D., Ph.D., Professor in thoracic oncology in the Multidisciplinary Oncology and Therapeutic Innovations department in Marseille, France. “A simple and readily available regimen that reduces dermatologic reactions by half and scalp-related reactions by more than three-fold is a major step forward, potentially allowing patients to stay on treatment longer.”
The study enrolled newly diagnosed patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletions (ex19del) or L858R substitution mutations. Patients were given either an enhanced preventative dermatologic regimen (the COCOON regimen, n=70), or standard dermatologic care (n=68). The COCOON regimen, designed to fit within a patient’s daily routine, included a twice-daily oral antibiotic (doxycycline or minocycline, 100 mg), an application of a topical antibiotic for the scalp (clindamycin 1 percent), an antiseptic wash for the hands and feet, used during regular handwashing or showering (chlorhexidine 4 percent), and a non-comedogenic ceramide-based moisturizer applied once daily.1
By Week 12, patients on the COCOON regimen had significantly fewer Grade 2 or higher dermatologic events compared to standard of care management (39 percent vs 77 percent; odds ratio [OR], 0.19; 95 percent confidence interval [CI], 0.09–0.40; P<0.0001), meeting the pre-specified endpoint of the study. The incidence of Grade 3 dermatologic events was reduced by more than 50 percent with the preventative regimen (4.3 percent vs 8.8 percent). Additionally, scalp-related Grade 2 or higher events were reduced by more than three-fold, and only one patient receiving the COCOON regimen experienced a Grade 3 scalp adverse reaction.1
Nearly two out of three patients on the COCOON regimen had no moderate to severe skin-related reactions. Patients receiving the COCOON regimen also appeared to experience lower rates of treatment discontinuations (11 percent vs 19 percent) on RYBREVANT® and LAZCLUZE™ due to any adverse reactions compared to standard of care.1
“Being diagnosed with EGFR-positive non-small cell lung cancer is hard enough — none of us signed up for it. But making treatment more manageable from the start makes a big difference,” said Jill Feldman**, lung cancer survivor and co-founder of the EGFR Resisters, a patient advocacy group. “Easing potential dermatologic effects improves the whole treatment experience — allowing us to focus on what really matters: our families, our passions, and truly living.”
“Our goal is to help patients get the most out of their RYBREVANT-based regimen,” said Mark Wildgust, Ph.D., Vice President of Oncology Global Medical Affairs, Johnson & Johnson Innovative Medicine. “Incorporating simple, preventative steps into daily routines can help manage skin and nail reactions, which may help patients stay on treatment, avoid treatment interruptions and improve their overall treatment experience.”
The study protocol is being amended to also evaluate the impact of different interventions for the treatment of new-onset or persistent dermatologic reactions in patients receiving RYBREVANT® and LAZCLUZE™ with the COCOON regimen. The study is also expanding to include a new cohort (Cohort C) to evaluate the COCOON regimen and early intervention with the subcutaneous formulation of amivantamab, administered every four weeks. This cohort aims to assess whether initiating reactive treatment at the first signs of skin and nail reactions (Grade 1) can further improve outcomes, rather than waiting for symptoms to progress.
About the COCOON Study
COCOON (NCT06120140) is a Phase 2, randomized, open-label, multicenter study evaluating the effectiveness of a prophylactic dermatologic regimen in reducing the incidence of skin and nail adverse reactions commonly associated with EGFR-targeted therapies. The fully enrolled study includes 201 patients, divided into two groups (Arm A vs Arm B). Arm A received an enhanced dermatologic care regimen designed to prevent skin and nail reactions, while Arm B received standard dermatologic care. The enhanced regimen includes an oral antibiotic (doxycycline or minocycline) administered twice daily for 12 weeks, followed by a topical antibiotic (clindamycin 1 percent), an antibacterial wash (chlorhexidine 4 percent), and a ceramide-based noncomedogenic moisturizer applied once daily alongside RYBREVANT® and oral LAZCLUZE™ as first-line treatment. The primary endpoint of the study is the incidence of Grade 2 or higher dermatologic reactions within the first 12 weeks of treatment. Key secondary endpoints include the incidence and severity of various dermatologic toxicities during the first year of treatment, their impact on patients’ quality of life, and progression-free survival, among others.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.6,7 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.8 Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase controlling cell growth and division.9 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.6,7,10,11,12,13 EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.14 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.15,16 EGFR exon 20 insertion mutations are the third most prevalent activating EGFR mutation.17 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.18
