Previously Treated NSCLC with EGFR Exon 19 Deletions or Exon 21 L858R Substitution Mutations RYBREVANT FASPRO, in combination with carboplatin and pemetrexed, is indicated for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations, whose disease has progressed on or after treatment with an EGFR tyrosine kinase inhibitor.

First-Line Treatment of NSCLC with EGFR Exon 20 Insertion Mutations RYBREVANT FASPRO, in combination with carboplatin and pemetrexed, is indicated for the first-line treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test.

Previously Treated NSCLC with EGFR Exon 20 Insertion Mutations RYBREVANT FASPRO is indicated as a single agent for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.

Dosage & Administration of Rybrevant Faspro

Important Dosage and Administration Information RYBREVANT FASPRO is for subcutaneous use only. Do not administer RYBREVANT FASPRO intravenously. RYBREVANT FASPRO must be administered by a healthcare professional.

To reduce the risk of medication errors, prior to administration, check the vial labels to ensure that the drug being prepared and administered is subcutaneous RYBREVANT FASPRO and not intravenous amivantamab. RYBREVANT FASPRO has different recommended dosage and administration than intravenous amivantamab products. Do not substitute RYBREVANT FASPRO for or with intravenous amivantamab products.

Adult patients currently receiving intravenous amivantamab at an every 2-week dosing regimen may switch to subcutaneous RYBREVANT FASPRO at an every 2-week dosing regimen or at an every 4-week dosing regimen at their next scheduled dose on or after Week 5. RYBREVANT FASPRO is not indicated for use in pediatric patients. Administer premedications before each RYBREVANT FASPRO dose as recommended, to reduce the risk of administration-related reactions (ARRs).

Administer each injection of RYBREVANT FASPRO subcutaneously in the abdomen over approximately 5 minutes to minimize injection site irritation. Do not inject into tattoos or scars or areas where the skin is red, bruised, tender, hard, not intact or within 2 inches (5 cm) around the periumbilical area. If the total dose requires multiple injections of RYBREVANT FASPRO, administer each injection consecutively in separate quadrants of the abdomen, with each injection taking approximately 5 minutes.

Rotate injection sites at the next scheduled dose. Pause or slow the delivery rate if the patient experiences pain. In the event pain is not alleviated by pausing or slowing down delivery rate, a second injection site may be chosen on the opposite side of the abdomen to deliver the remainder of the dose.

If administering with a subcutaneous infusion set, ensure that the full dose is delivered through the infusion set, 0.9% sodium chloride solution may be utilized to flush remaining drug product through the line. Discard unused portion.

Refer to the lazertinib prescribing information for recommended lazertinib dosing information.

Recommended Premedications Prior to the initial injection of RYBREVANT FASPRO (Week 1 Day 1), administer premedications as described in Table 6 to reduce the risk of administration-related reactions. Glucocorticoid administration is required at the initial dose at Week 1 Day 1 only, and upon re-initiation after prolonged dose interruptions, then as necessary for subsequent injections. Administer both antihistamine and antipyretic prior to all, prophylactic and concomitant medications are recommended to reduce the risk and severity of dermatologic adverse reactions.

Administer an oral antibiotic (doxycycline or minocycline, 100 mg orally twice daily) starting on Day 1 for the first 12 weeks of treatment. After completion of oral antibiotic treatment, administer antibiotic lotion to the scalp (clindamycin 1% topical once daily) for the next 9 months of treatment. Administer non-comedogenic skin moisturizer (ceramide-based or other formulations that provide long-lasting skin hydration and exclude drying agents) on the face and whole body (except scalp).

Wash hands and feet with 4% chlorhexidine solution once daily. Limit sun exposure during and for 2 months after treatment. Advise patients to wear protective clothing and use broad-spectrum UVA/UVB sunscreen to reduce the risk of dermatologic adverse reactions.

RYBREVANT FASPRO in Combination with Lazertinib: Concomitant Medications to Reduce the Risk of Venous Thromboembolic Events When initiating treatment with RYBREVANT FASPRO in combination with lazertinib, administer anticoagulant prophylaxis to prevent venous thromboembolic (VTE) events for the first four months of treatment. If there are no signs or symptoms of VTE during the first four months of treatment, consider discontinuation of anticoagulant prophylaxis at the discretion of the healthcare provider. Refer to the lazertinib prescribing information for information about concomitant medications.

Warnings & Cautions for Rybrevant Faspro

Hypersensitivity and Administration-Related Reactions RYBREVANT FASPRO can cause hypersensitivity and administration-related reactions (ARR); signs and symptoms of ARR include dyspnea, flushing, fever, chills, chest discomfort, hypotension, and vomiting. The median time to ARR onset is approximately 2 hours. Local injection site reactions are described separately in Section 6.1.

Of the patients who experienced ARR, 89% occurred with the initial dose (Week 1, Day 1). Premedicate with antihistamines, antipyretics, and glucocorticoids and administer RYBREVANT FASPRO as recommended. Monitor patients for any signs and symptoms of administration-related reactions during injection in a setting where cardiopulmonary resuscitation medication and equipment are available.

Interrupt RYBREVANT FASPRO injection, if ARR is suspected. Resume treatment upon resolution of symptoms or permanently discontinue RYBREVANT FASPRO based on severity.

Interstitial Lung Disease/Pneumonitis RYBREVANT FASPRO can cause severe and fatal interstitial lung disease (ILD)/pneumonitis. In total, 5% of patients permanently discontinued RYBREVANT FASPRO and lazertinib due to ILD/pneumonitis. There was one fatal case of ILD/pneumonitis and 2.9% of patients permanently discontinued intravenous amivantamab and lazertinib due to ILD/pneumonitis.

Intravenous Amivantamab with Carboplatin and Pemetrexed Based on the pooled safety population, in 281 patients who received intravenous amivantamab in combination with carboplatin and pemetrexed, ILD/pneumonitis occurred in 2.1%, including 1.8% Grade 3 ILD/pneumonitis. Of these, 2.1% of patients permanently discontinued intravenous amivantamab due to ILD/pneumonitis. Monitor patients for new or worsening symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, fever).

Immediately withhold RYBREVANT FASPRO in patients with suspected ILD/pneumonitis and permanently discontinue if ILD/pneumonitis is confirmed.

Venous Thromboembolic (VTE) Events with Concomitant Use with Lazertinib RYBREVANT FASPRO in combination with lazertinib can cause serious and fatal venous thromboembolic (VTE) events, including deep vein thrombosis and pulmonary embolism. Without prophylactic anticoagulation, the majority of these events occurred during the first four months of therapy. Of the 206 patients treated with RYBREVANT FASPRO in combination with lazertinib, 80% received prophylactic anticoagulation at study entry.

In the 164 patients treated with RYBREVANT FASPRO in combination with lazertinib who received prophylactic anticoagulation, all Grade VTE occurred in 7%. In the 42 patients treated with RYBREVANT FASPRO in combination with lazertinib who did not receive prophylactic anticoagulation, all Grade VTE occurred in 17%. In total, 0.5% of patients had VTE leading to dose reductions of RYBREVANT FASPRO and no patients required permanent discontinuation.

The median time to onset of VTEs was 95 days (range: 17 to 390). On-study VTEs occurred in 1.2% of patients (n=5) while receiving anticoagulation therapy. There were two fatal cases of VTE (0.5%), 9% of patients had VTE leading to dose interruptions of intravenous amivantamab, 1% of patients had VTE leading to dose reductions of intravenous amivantamab, and 3.1% of patients had VTE leading to permanent discontinuation of intravenous amivantamab.

The median time to onset of VTEs was 84 days (range: 6 to 777). Administer prophylactic anticoagulation for the first four months of treatment. The use of Vitamin K antagonists is not recommended.

Monitor for signs and symptoms of VTE events and treat as medically appropriate. Withhold RYBREVANT FASPRO and lazertinib based on severity. Once anticoagulant treatment has been initiated, resume RYBREVANT FASPRO and lazertinib at the same dose level at the discretion of the healthcare provider.

In the event of VTE recurrence despite therapeutic anticoagulation, permanently discontinue RYBREVANT FASPRO. Treatment can continue with lazertinib at the same dose level at the discretion of the healthcare provider. Refer to the lazertinib prescribing information for recommended lazertinib dosage modification.

Dermatologic Adverse Reactions RYBREVANT FASPRO can cause severe rash including toxic epidermal necrolysis (TEN), dermatitis acneiform, pruritus and dry skin. Rash leading to dose reduction occurred in 11% of patients, and RYBREVANT FASPRO was permanently discontinued due to rash in 1.5% of patients. The median time to onset of rash was 14 days (range: 1 to 556 days).

Rash leading to dose interruptions of intravenous amivantamab occurred in 37% of patients, rash leading to dose reductions of intravenous amivantamab occurred in 23% of patients, and rash leading to permanent discontinuation of intravenous amivantamab occurred in 5% of patients. Intravenous Amivantamab with Carboplatin and Pemetrexed Based on the pooled safety population, in 281 patients who received intravenous amivantamab in combination with carboplatin and pemetrexed, rash occurred in 82%, including 15% Grade 3. Rash leading to dose reductions occurred in 14% of patients, and 2.5% permanently discontinued intravenous amivantamab and 3.1% discontinued pemetrexed.

Rash leading to dose reduction occurred in 5% of patients, and intravenous amivantamab was permanently discontinued due to rash in 0.7% of patients. Toxic epidermal necrolysis (TEN) occurred in one patient (0.3%) treated with intravenous amivantamab as a single agent. When initiating treatment with RYBREVANT FASPRO, prophylactic and concomitant medications are recommended to reduce the risk and severity of dermatologic adverse reactions.

Instruct patients to limit sun exposure during and for 2 months after treatment with RYBREVANT FASPRO. Advise patients to wear protective clothing and use broad-spectrum UVA/UVB sunscreen. If skin reactions develop, administer supportive care including topical corticosteroids and topical and/or oral antibiotics.

For Grade 3 reactions, add oral steroids and consider dermatologic consultation. Promptly refer patients presenting with severe rash, atypical appearance or distribution, or lack of improvement within 2 weeks to a dermatologist. Withhold, dose reduce or permanently discontinue RYBREVANT FASPRO based on severity.

Ocular Toxicity RYBREVANT FASPRO can cause ocular toxicity including keratitis, blepharitis, dry eye symptoms, conjunctival redness, blurred vision, visual impairment, ocular itching, eye pruritus and uveitis. Intravenous Amivantamab with Carboplatin and Pemetrexed Based on the pooled safety population, in 281 patients who received intravenous amivantamab in combination with carboplatin and pemetrexed, ocular toxicity occurred in 16%. All events were Grade 1 or 2.

Intravenous Amivantamab as a Single Agent In CHRYSALIS, in 302 patients treated with intravenous amivantamab, keratitis occurred in 0.7% and uveitis occurred in 0.3%. Promptly refer patients presenting with new or worsening eye symptoms to an ophthalmologist.

Embryo-Fetal Toxicity Based on its mechanism of action and findings from animal models, RYBREVANT FASPRO can cause fetal harm when administered to a pregnant woman. Administration of other EGFR inhibitor molecules to pregnant animals has resulted in an increased incidence of impairment of embryo-fetal development, embryo lethality, and abortion. Verify pregnancy status of females of reproductive potential prior to initiating RYBREVANT FASPRO.

Advise pregnant women and females of reproductive potential of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during treatment and for 3 months after the last dose of RYBREVANT FASPRO.

Pregnancy Safety for Rybrevant Faspro

Pregnancy Risk Summary Based on the mechanism of action and findings in animal models, RYBREVANT FASPRO can cause fetal harm when administered to a pregnant woman. There are no available data on the use of RYBREVANT FASPRO in pregnant women or animal data to assess the risk of RYBREVANT FASPRO in pregnancy. Disruption or depletion of EGFR in animal models resulted in impairment of embryo-fetal development including effects on placental, lung, cardiac, skin, and neural development.

The absence of EGFR or MET signaling has resulted in embryo lethality, malformations, and post-natal death in animals (see Data ). Advise pregnant women and females of reproductive potential of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is respectively.

Data Animal Data RYBREVANT FASPRO for subcutaneous injection contains amivantamab and hyaluronidase. Amivantamab: No animal studies have been conducted to evaluate the effects of amivantamab on reproduction and fetal development; however, based on its mechanism of action, RYBREVANT FASPRO can cause fetal harm or developmental anomalies. In mice, EGFR is critically important in reproductive and developmental processes including blastocyst implantation, placental development, and embryo-fetal/postnatal survival and development.

Reduction or elimination of embryo-fetal or maternal EGFR signaling can prevent implantation, can cause embryo-fetal loss during various stages of gestation (through effects on placental development) and can cause developmental anomalies and early death in surviving fetuses. Adverse developmental outcomes were observed in multiple organs in embryos/neonates of mice with disrupted EGFR signaling. Similarly, knock out of MET or its ligand HGF was embryonic lethal due to severe defects in placental development, and fetuses displayed defects in muscle development in multiple organs.

Human IgG1 is known to cross the placenta; therefore, amivantamab has the potential to be transmitted from the mother to the developing fetus. Hyaluronidase: In an embryo-fetal study, mice were dosed daily by subcutaneous injection during the period of organogenesis with hyaluronidase (recombinant human) at dose levels up to 2,200,000 U/kg, which is > 3600 times higher than the human dose. The study found no evidence of teratogenicity.

Reduced fetal weight and increased numbers of fetal resorptions were observed, with no effects found at a daily dose of 360,000 U/kg, which is > 600 times higher than the human dose. In a peri-and post-natal reproduction study, mice have been dosed daily by subcutaneous injection, with hyaluronidase (recombinant human) from implantation through lactation and weaning at dose levels up to 1,100,000 U/kg, which is > 1800 times higher than the human dose. The study found no adverse effects on sexual maturation, learning and memory or fertility of the offspring.

Pediatric Use of Rybrevant Faspro

Pediatric Use The safety and efficacy of RYBREVANT FASPRO have not been established in pediatric patients.

Contraindications for Rybrevant Faspro

RYBREVANT FASPRO is contraindicated in patients with known hypersensitivity to hyaluronidase or to any of its excipients.

Clinical Studies of Rybrevant Faspro

First-Line Treatment of NSCLC with EGFR Exon 19 Deletions or Exon 21 L858R Substitution Mutations – Intravenous Amivantamab in Combination with Lazertinib MARIPOSA The efficacy of intravenous amivantamab, in combination with lazertinib, was evaluated in MARIPOSA (NCT04487080), a randomized, active-controlled, multicenter trial. Eligible patients were required to have untreated locally advanced or metastatic NSCLC with either exon 19 deletions or exon 21 L858R substitution EGFR mutations identified by local testing, not amenable to curative therapy. Patients with asymptomatic or previously treated and stable intracranial metastases were eligible to enroll.

Patients were randomized (2:2:1) to receive intravenous amivantamab in combination with lazertinib (N=429), osimertinib monotherapy (N=429), or lazertinib monotherapy (an unapproved regimen for NSCLC) until disease progression or unacceptable toxicity. Osimertinib administered at a dose of 80 mg orally once daily. Randomization was stratified by EGFR mutation type (exon 19 deletion or exon 21 L858R substitution mutation), Asian race (yes or no), and history of brain metastasis (yes or no).

Tumor assessments were performed every 8 weeks for 30 months, and then every 12 weeks until disease progression. The major efficacy outcome measure was progression-free survival (PFS) as assessed by blinded independent central review (BICR). Additional efficacy outcome measures included overall survival (OS), overall response rate (ORR), and duration of response (DOR).

A total of 858 patients were randomized between the two study arms, 429 to the intravenous amivantamab in combination with lazertinib arm and 429 to the osimertinib arm. Eastern Cooperative Oncology Group (ECOG) performance status was never smoked; 41% had prior brain metastases; and 89% had Stage IV cancer at initial diagnosis. Sixty percent of patients had tumors harboring exon 19 deletions and the remaining 40% had exon 21 L858R substitution mutations.

Among the 858 patients with EGFR exon 19 deletion or L858R substitution mutations that were randomized between the intravenous amivantamab plus lazertinib arm versus the osimertinib arm, available tissue samples from 544 (63%) patients had evaluable results when tested retrospectively using the cobas EGFR Mutation Test v2. Available plasma samples from patients were retrospectively tested using an FDA-approved test to confirm the biomarker status. The trial demonstrated a statistically significant improvement in PFS by BICR assessment and OS for intravenous amivantamab in combination with lazertinib compared to osimertinib (see Table 21 and Figures 1 and 2 ).

Efficacy results for intravenous amivantamab in combination with lazertinib are provided in Table 21. Table 21: Efficacy Results in MARIPOSA by BICR Assessment Figure 1: Kaplan-Meier Curves of PFS by BICR Assessment in Patients with Previously Untreated NSCLC Figure 2: Kaplan-Meier Curves of OS in Patients with Previously Untreated NSCLC Out of all randomized patients (n=858), 367 (43%) had baseline intracranial lesions assessed by BICR using modified RECIST. Results of pre-specified analyses of intracranial ORR and DOR by BICR in the subset of patients with intracranial lesions at baseline for the intravenous amivantamab in combination with lazertinib arm and the osimertinib arm are summarized in Table 22.

Previously Treated NSCLC with EGFR Exon 19 Deletions or Exon 21 L858R Substitution Mutations – Intravenous Amivantamab in Combination with Carboplatin and Pemetrexed MARIPOSA-2 The efficacy of intravenous amivantamab in combination with carboplatin and pemetrexed was evaluated in MARIPOSA-2 (NCT04988295), a randomized, open-label, multicenter trial. Eligible patients were required to have locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations and progressive disease on or after receiving osimertinib. Patients were randomized (1:2:2) to receive intravenous amivantamab in combination with carboplatin and pemetrexed (intravenous amivantamab-CP, N=131), carboplatin and pemetrexed (CP, N=263), or intravenous amivantamab as part of another combination regimen.

The evaluation of efficacy for metastatic NSCLC relied upon comparison between: Intravenous amivantamab in combination with carboplatin and pemetrexed. Platinum-based chemotherapy with carboplatin and pemetrexed. Randomization was stratified by osimertinib line of therapy (first-line or second-line), prior brain metastases (yes or no), and Asian race (yes or no).

Tumor assessments were performed every 6 weeks for the first 12 months and every 12 weeks thereafter. Overall survival (OS) and overall response rate (ORR) as assessed by BICR were key secondary outcome measures. A total of 394 patients were randomized between the two arms, 131 to the intravenous amivantamab-CP arm and 263 to the CP arm.

Baseline Eastern Cooperative Oncology Group (ECOG) performance status was never smoked; 45% had history of brain metastasis, and 99.7% had Stage IV cancer at study enrollment. Efficacy results are summarized in Table 5.6 Figure 3: Kaplan-Meier Curve of PFS in Previously Treated NSCLC Patients by BICR Assessment - MARIPOSA-2 At the prespecified second interim analysis of OS, with 85% of the deaths needed for the final analysis, there was no statistically significant difference in OS. Baseline disease assessment, including brain magnetic resonance imaging (MRI) was performed at treatment initiation.

All patients underwent serial brain MRI during the trial. Pre-specified secondary analyses of intracranial ORR by BICR in the subset of 91 (23%) patients with baseline intracranial disease were performed. Data were only available for intracranial complete responses and not available for intracranial partial responses.

Intracranial ORR was in the 30 patients with baseline intracranial disease in the ACP arm and in the 61 patients with baseline intracranial disease in the CP arm. Figure 3

First-Line Treatment of NSCLC with EGFR Exon 20 Insertion Mutations – Intravenous Amivantamab in Combination with Carboplatin and Pemetrexed PAPILLON The efficacy of intravenous amivantamab was evaluated in PAPILLON (NCT04538664), in a randomized, open-label, multicenter study. Eligible patients were required to have previously untreated locally advanced or metastatic NSCLC with EGFR Exon 20 insertion mutations measurable disease per RECIST v1.1, Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤ 1, and adequate organ and bone marrow function. Patients with brain metastases at screening were eligible for participation once they were definitively treated, clinically stable, asymptomatic, and off corticosteroid treatment for at least 2 weeks prior to randomization.

Patients with a medical history of interstitial lung disease or active ILD were excluded from the clinical study. A total of 308 patients were randomized 1:1 to receive intravenous amivantamab in combination with carboplatin and pemetrexed (n=153) or carboplatin and pemetrexed (n=155). Pemetrexed was administered intravenously at 500 mg/m 2 on once every 3 weeks until disease progression or unacceptable toxicity.

Patients were stratified by Eastern Cooperative Oncology Group (ECOG) performance status (0 or 1) and prior brain metastases (yes or no). Cross-over to single agent intravenous amivantamab was permitted for patients who had confirmed disease progression on carboplatin and pemetrexed. Baseline ECOG performance status was were never smokers; 23% had history of brain metastasis and 84% had Stage IV cancer at initial diagnosis.

PAPILLON demonstrated a statistically significant improvement in progression free survival for patients randomized to intravenous amivantamab in combination with carboplatin and pemetrexed compared with carboplatin and pemetrexed. Efficacy results are summarized in Table 24 and Figure 4. Table 24: Efficacy Results in PAPILLON 10.1 5.6 Figure 4: Kaplan-Meier Curve of PFS in Previously Untreated NSCLC Patients by BICR Assessment – PAPILLON Study While OS results were immature at the current analysis, with 44% of pre-specified deaths for the final analysis reported, no trend towards a detriment was observed.

Seventy-five (48%) of the treated patients crossed over from the carboplatin and pemetrexed arm after confirmation of disease progression to receive intravenous amivantamab as a single agent. Figure 4

Previously Treated NSCLC with EGFR Exon 20 Insertion Mutations – Intravenous Amivantamab as a Single Agent CHRYSALIS The efficacy of intravenous amivantamab was evaluated in patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations in a multicenter, open-label, multi-cohort clinical trial (CHRYSALIS, NCT02609776). The study included patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations whose disease had progressed on or after platinum-based chemotherapy. Patients with untreated brain metastases and patients with a history of ILD requiring treatment with prolonged steroids or other immunosuppressive agents within the last 2 years were not eligible for the study.

In the efficacy population, EGFR exon 20 insertion mutation status was determined by prospective local testing using tissue (94%) and/or plasma (6%) samples. The major efficacy outcome measure was overall response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) as evaluated by Blinded Independent Central Review (BICR). An additional efficacy outcome measure was duration of response (DOR) by BICR.

The efficacy population included 81 patients with NSCLC with EGFR exon 20 insertion mutation with measurable disease who were previously treated with platinum-based chemotherapy. The median number of prior therapies was 2 (range: 1 to 7). Efficacy results are summarized in Table 25.
