5. Warnings and Precautions

5.1 Ocular Toxicities

AVMAPKI FAKZYNJA CO-PACK can cause ocular adverse reactions, including visual impairment and vitreoretinal disorders.

Ocular adverse reactions occurred in 68% of patients with recurrent LGSOC treated with AVMAPKI FAKZYNJA CO-PACK. Common ocular adverse reactions (≥ 5%) were visual impairment (38%), dry eye (13%), orbital/periorbital edema (8%), and vitreous floaters (5%). Thirty-five patients (26%) experienced vitreoretinal disorders, including retinal detachment (9%), and retinal vein occlusion (0.7%). Eighteen patients (13%) experienced an ocular adverse reaction that resulted in dose interruption of AVMAPKI FAKZYNJA CO-PACK and one patient experienced an ocular adverse reaction that resulted in dose reduction.

The median time to onset of symptomatic ocular adverse reactions was 5 days (range 1 to 943 days) and to onset of asymptomatic ocular adverse reactions was 112 days (range 23 to 943 days). The median time to onset of retinal detachment was 27 days (range 2 to 535 days). Of the patients who experienced ocular adverse reactions, 29% had ongoing ocular events at last follow-up.

Refer patients to a qualified eye care professional for a comprehensive ophthalmic exam at baseline, prior to cycle 2, every three cycles thereafter, and as clinically indicated. Promptly refer patients to an eye care professional for any new or worsening ocular signs or symptoms.

Monitor for ocular adverse reactions and withhold, reduce, or permanently discontinue AVMAPKI FAKZYNJA CO-PACK based on severity and persistence of ocular adverse reactions [see Dosage and Administration (2.4)].

5.2 Serious Skin Toxicities

AVMAPKI FAKZYNJA CO-PACK can cause serious skin toxicities, including Severe Cutaneous Adverse Reactions (SCARs). Cases of acute generalized exanthematous pustulosis, erythema multiforme and drug reaction with eosinophilia and systemic symptoms have been reported in clinical trials of avutometinib (a drug in AVMAPKI FAKZYNJA CO-PACK).

Skin toxicities occurred in 94% of patients with recurrent LGSOC treated with AVMAPKI FAKZYNJA CO-PACK. The most common skin toxicities (≥ 10%) were rash (67%), dermatitis acneiform (43%), dry skin (43%), pruritus (32%), and photosensitivity (13%). Grade 3 skin reactions occurred in 12% of patients including dermatitis acneiform (7%), rash (7%), and pruritus (1.5%). Thirteen patients (10%) developed bacterial skin infections. Skin toxicity led to dose interruption of AVMAPKI FAKZYNJA CO-PACK in 10%, to dose reduction in 7%, and to permanent discontinuation in 0.7% of patients. The median time to onset of the first skin toxicity was 14 days (range 1 to 500 days). At last follow-up, 66% of patients had ongoing skin toxicity.

Patients in RAMP-201 used topical corticosteroids (applied to the face, scalp, neck, upper chest and upper back) and systemic oral antibiotics for prophylaxis of skin adverse reactions. These medications were initiated at the start of AVMAPKI FAKZYNJA CO-PACK and administered during at least the first two cycles of treatment.

Limit unnecessary exposure to sunlight and apply daily sunscreen (sun protection factor [SPF] ≥ 30). Monitor for skin toxicity and withhold, reduce dose, or permanently discontinue AVMAPKI FAKZYNJA CO-PACK based on severity and persistence [see Dosage and Administration (2.4)].

5.3 Hepatotoxicity

AVMAPKI FAKZYNJA CO-PACK can cause hepatotoxicity.

In patients with recurrent LGSOC who received AVMAPKI FAKZYNJA CO-PACK, increased AST (73%), bilirubin (51%), ALT (49%), and alkaline phosphatase (46%) occurred. Grade 3-4 elevations in ALT was 3%, AST was 3%, bilirubin was 2.3% and alkaline phosphatase was 0.8%. Elevations in one or more liver related laboratory values led to dose interruption for 20%, dose reduction for 2.2%, and permanent discontinuation for 0.7% of patients.

Increased blood bilirubin may be attributed to defactinib (a component of AVMAPKI FAKZYNJA CO-PACK) due to the inhibition of enzymes responsible for metabolizing (uridine diphosphate-glucuronosyltransferase (UGT)1A1) and transporting (Organic Anion Transporting Polypeptides (OATP)1B1/1B3) bilirubin [see Clinical Pharmacology (12.3)].

Monitor liver related laboratory values prior to the start of each cycle, on day 15 of the first four cycles, and as clinically indicated. Withhold, reduce dose, or permanently discontinue AVMAPKI FAKZYNJA CO-PACK based on severity and duration of these adverse reactions [see Dosage and Administration (2.4)].

5.4 Rhabdomyolysis

AVMAPKI FAKZYNJA CO-PACK can cause increased creatine phosphokinase (CPK). Increased CPK occurred in 75% of patients with recurrent LGSOC treated with AVMAPKI FAKZYNJA CO-PACK, including Grade 3-4 elevations in 18% of patients. Among the patients who experienced an elevation in CPK, concurrent increase in creatinine occurred in 19% (n=19/102) and myalgia occurred in 10% (n=10/102). Elevation of CPK >10 times the baseline value with a concurrent increase in serum creatinine of ≥1.5 times the baseline value occurred in 0.7% of patients. Increased CPK resulted in dose interruption for 22%, in dose reduction for 7%, and in discontinuation for 2.9% of patients. Rhabdomyolysis has occurred in a patient with LGSOC treated with AVMAPKI FAKZYNJA CO-PACK at the recommended dosage in a clinical trial.

Monitor CPK prior to the start of each cycle, on day 15 of the first four cycles, and as clinically indicated. If increased CPK occurs, evaluate patients for rhabdomyolysis or other causes. Withhold, reduce or permanently discontinue AVMAPKI FAKZYNJA CO-PACK based on severity and duration of the adverse reactions [see Dose Modifications (2.4)].

5.5 Embryo-Fetal Toxicity

Based on the mechanisms of action, AVMAPKI FAKZYNJA CO-PACK can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. Inhibition of either molecular pathway has been associated with embryo-fetal anomalies and lethality in animals.

Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with AVMAPKI FAKZYNJA CO-PACK and for 1 month after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with AVMAPKI FAKZYNJA CO-PACK and for 4 months after the last dose [see Use in Specific Populations (8.3)].

6. Adverse Reactions/Side Effects

The following adverse reactions are discussed in more detail in other sections of the labeling:

Ocular Toxicities [see Warnings and Precautions (5.1)]
Serious Skin Toxicities [see Warnings and Precautions (5.2)]
Hepatotoxicity [see Warnings and Precautions (5.3)]
Rhabdomyolysis [see Warnings and Precautions (5.4)]

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The pooled safety population described in Warnings and Precautions reflect exposure to the AVMAPKI FAKZYNJA CO-PACK (combination of AVMAPKI 3.2 mg twice weekly and FAKZYNJA 200 mg twice daily) for the first 3 weeks in a 4-week cycle until disease progression or unacceptable toxicity in 136 adult patients with recurrent LGSOC treated on RAMP-201 and FRAME (NCT03875820). The median duration of treatment was 10 months (range 0 to 51 months).

RAMP-201

The safety of AVMAPKI FAKZYNJA CO-PACK was evaluated in RAMP-201, a single-arm multicenter trial in 57 patients with KRAS-mutated recurrent LGSOC [see Clinical Studies (14)]. Patients received AVMAPKI FAKZYNJA CO-PACK (AVMAPKI 3.2 mg twice weekly and FAKZYNJA 200 mg twice daily) for the first 3 weeks in a 4-week cycle until disease progression or unacceptable toxicity. The median duration of treatment was 12 months (range 0.03-40).

Serious adverse reactions occurred in 32% of patients who received AVMAPKI FAKZYNJA CO-PACK. The most common (≥2%) serious adverse reactions were sepsis (9%), intestinal obstruction (3.6%), pyelonephritis (3.6%), and hydronephrosis (3.6%). Fatal adverse reactions occurred in 3.6% of patients who received AVMAPKI FAKZYNJA CO-PACK, including intestinal obstruction (1.8%) and perforation (1.8%).

7. Drug Interactions

7.1 Effect of Other Drugs on AVMAPKI FAKZYNJA CO-PACK

Strong and Moderate CYP3A4 Inhibitors

Avoid concomitant use of AVMAPKI FAKZYNJA CO-PACK with strong or moderate CYP3A4 inhibitors.

Defactinib is a CYP3A4 substrate. Concomitant use of defactinib with a strong CYP3A4 inhibitor increases defactinib exposure [see Clinical Pharmacology (12.3)], which may increase the risk of AVMAPKI FAKZYNJA CO-PACK adverse reactions.

Strong and Moderate CYP3A4 Inducers

Avoid concomitant use of AVMAPKI FAKZYNJA CO-PACK with strong or moderate CYP3A4 inducers.

Defactinib is a CYP3A4 substrate. Concomitant use of defactinib with a strong CYP3A4 inducer decreases defactinib exposure, which may reduce the effectiveness of FAKZYNJA [see Clinical Pharmacology (12.3)].

Gastric Acid Reducing Agents

Avoid concomitant use of AVMAPKI FAKZYNJA CO-PACK with proton pump inhibitors (PPIs) or H2 receptor antagonists. If concomitant use of an acid-reducing agent cannot be avoided, administer FAKZYNJA 2 hours before or 2 hours after the administration of a locally acting antacid.

Concomitant use of FAKZYNJA with gastric acid reducing agents decreases defactinib exposure, which may reduce the effectiveness of AVMAPKI FAKZYNJA CO-PACK [see Clinical Pharmacology (12.3)].

7.2 Effect of AVMAPKI FAKZYNJA CO-PACK on Other Drugs

Warfarin

Avoid concomitant use of AVMAPKI FAKZYNJA CO-PACK with warfarin. For patients requiring anticoagulation, an alternative to warfarin is recommended. If concomitant use is unavoidable, monitor INR frequently during treatment with AVMAPKI FAKZYNJA CO-PACK.

Cases of bleeding and increased INR occurred in patients taking FAKZYNJA concomitantly with warfarin in clinical trials.

8. Use In Specific Populations

8.1 Pregnancy

Risk Summary

Based on the mechanisms of action, AVMAPKI FAKZYNJA CO-PACK can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on the use of AVMAPKI FAKZYNJA CO-PACK in pregnant women to inform a drug-associated risk. Animal reproductive and developmental toxicity studies have not been conducted with avutometinib or defactinib; however, inhibition of either molecular pathway has been associated with embryo-fetal anomalies and lethality in animals. Advise pregnant women and females of reproductive potential of the potential risk to a fetus.

The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

8.2 Lactation

Risk Summary

There are no data on the presence of avutometinib, defactinib, or their metabolites in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise lactating women not to breastfeed during treatment with AVMAPKI FAKZYNJA CO-PACK and for 2 weeks after the last dose.

8.3 Females and Males of Reproductive Potential

AVMAPKI FAKZYNJA CO-PACK can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].

Pregnancy Testing

Verify the pregnancy status of females of reproductive potential prior to initiating treatment with AVMAPKI FAKZYNJA CO-PACK.

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with AVMAPKI FAKZYNJA CO-PACK and for 1 month after the last dose.

Males

Advise male patients with female partners of reproductive potential to use effective contraception during treatment with AVMAPKI FAKZYNJA CO-PACK and for 4 months after the last dose.

Infertility

Based on animal studies, AVMAPKI FAKZYNJA CO-PACK may impair fertility in females and males of reproductive potential. The effects on fertility were not reversible in animals [see Nonclinical Toxicology (13.1)].

8.4 Pediatric Use

The safety and effectiveness of AVMAPKI FAKZYNJA CO-PACK in pediatric patients has not been established.

8.5 Geriatric Use

Of the 136 patients in clinical studies of AVMAPKI FAKZYNJA CO-PACK, 29% were age 65 years or older. No overall differences in safety were observed between patients age 65 years or older and younger patients. Clinical studies of AVMAPKI FAKZYNJA CO-PACK did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.

12. Amapki Fakzynja Co-Pack - Clinical Pharmacology

12.1 Mechanism of Action

Avutometinib

Avutometinib is a MEK1 inhibitor. Avutometinib induces the formation of inactive RAF/MEK complexes and prevents phosphorylation of MEK1/2 by RAF. RAF and MEK proteins are regulators of the RAS/RAF/MEK/ERK (MAPK) pathway. Avutometinib inhibited MEK1/2 and ERK1/2 phosphorylation and proliferation of tumor cell lines harboring KRAS mutations. Treatment of cancer cells with avutometinib increased the level of phosphorylated focal adhesion kinase (FAK).

Defactinib

Defactinib is an inhibitor of FAK and proline-rich tyrosine kinase-2 (Pyk2), the two members of the FAK family of nonreceptor tyrosine kinases. Defactinib inhibited FAK autophosphorylation in cancer cells in vitro and in mouse xenograft models.

Avutometinib in combination with defactinib enhanced inhibition of cell proliferation in vitro and anti-tumor activity in mouse tumor models including LGSOC.

12.2 Pharmacodynamics

Avutometinib exposure-response relationships and the time course of pharmacodynamic response have not been fully characterized.

Defactinib exposure-response relationships and the time course of pharmacodynamic response have not been fully characterized.

Cardiac Electrophysiology

At the recommended doses for AVMAPKI FAKZYNJA CO-PACK, a mean increase in the QTc interval >20 msec was not observed. For the 88 patients with PR interval measured in RAMP-201, the mean PR interval increased by 16 msec from baseline to Cycle 1 Day 15 4-hours post dose.

12.3 Pharmacokinetics

The pharmacokinetics of avutometinib and defactinib were studied in healthy subjects and in patients with advanced solid tumors and are presented as mean (%CV) unless otherwise specified.

Avutometinib

Avutometinib exhibits dose proportional increases peak plasma concentrations (Cmax) and area under the concentration time curve (AUC) with a single dose ranging from 0.1 mg to 5 mg (0.03 to 1.6 times the approved recommended dose). No significant accumulation of avutometinib was observed at the recommended dosage.

Defactinib

Defactinib exhibits dose proportional increases in Cmax and AUC with twice daily dosing ranging from 12.5 mg to 450 mg (0.06 to 2.25 times the approved recommended dosage). Defactinib steady-state plasma concentrations are reached in approximately 15 days. Defactinib accumulation is approximately 1.5-fold at the approved recommended dosage.

Absorption

The median time to avutometinib peak plasma concentration (Tmax) under fasted conditions is approximately 2 hours.

The median time to defactinib Tmax under fed conditions is approximately 4 hours.

Effect of Food

No clinically significant differences in avutometinib AUC were observed following administration with a high-fat meal. Avutometinib Cmax was decreased by 29% following administration with a high-fat meal (approximately 900 to 1000 calories, 50% fat).

Defactinib AUC increased by 2.7-fold and Cmax increased by 1.9-fold following administration with a high-fat meal (approximately 900 to 1000 calories, 50% fat).

Distribution

Avutometinib steady state apparent volume of distribution (Vd) is 25 L (19%). Avutometinib human plasma protein binding is 99% in vitro.

Defactinib steady state apparent Vd is 1,560 L (59%). Defactinib human plasma protein binding is 90% in vitro.

Elimination

Avutometinib estimated elimination half-life is 51 hours (28%) and the apparent oral clearance (CL/F) is 0.3 L/h (30%).

Defactinib estimated elimination half-life is 9 hours (171%) and the CL/F is 69 L/h (173%).

Metabolism

Avutometinib is primarily metabolized by CYP3A4 and nonenzymatic degradation.

Defactinib is metabolized primarily by CYP3A4 and CYP2C9. Two major metabolites, N-desmethyl sulfonamide (M2) and N-desmethyl amide (M4), were identified in plasma. M2 and M4 AUCs represent 92% and 28% of defactinib exposure, respectively. M2 is inactive and M4 is equipotent when compared to defactinib.

Excretion

After a single dose of radiolabeled avutometinib 2.4 mg (0.8 times the approved recommended dose), 39% (9.5% unchanged) of the dose was recovered in feces and 52% (3.2% unchanged) in urine.

After a single dose of radiolabeled defactinib 400 mg (2 times the approved recommended dose), 87% (52% unchanged) of the dose was recovered in feces and 7.6% (0.8% unchanged) in urine.

In repeat-dose toxicity studies up to 13-weeks duration in rats and monkeys, tissue mineralization in multiple organs was observed at doses ≥ 0.01 mg/kg/day and 0.03 mg/kg/day, respectively (≥ 0.06 and 1.4 times the human exposure at the recommended dose based on AUC, respectively) as well as increased inorganic phosphorus in rats.

In a cardiovascular telemetry study in monkeys, a single oral dose of avutometinib increased systolic, diastolic, and mean blood pressure at 1 mg/kg (approximately 15 times the human Cmax at the recommended dose). In the repeat-dose toxicology studies up to 13-weeks duration in rats, myocardial degeneration and necrosis were observed at doses ≥ 0.01 mg/kg/day (below the human exposure at the recommended dose based on AUC).

Defactinib

In a cardiovascular telemetry study in dogs, a single oral dose of defactinib decreased myocardial contractility at doses ≥ 5 mg/kg (approximately the human exposure at the recommended dose based on AUC) and increased ventricular systolic, diastolic and mean blood pressure at doses ≥ 25 mg/kg/day (≥ 2.7 times the human exposure at the recommended dose based on AUC). In the 13-week repeat-dose toxicology study in dogs, myocardium hypertrophy was observed at doses ≥ 1 mg/kg/day (below the human exposure at the recommended dose based on AUC) at the end of the dosing and recovery periods.

14. Clinical Studies

The efficacy of AVMAPKI FAKZYNJA CO-PACK was evaluated in RAMP-201 (NCT04625270), an open-label, multicenter study that included 57 adult patients with measurable KRAS-mutated recurrent LGSOC. Patients were required to have received at least one prior systemic therapy, including a platinum-based regimen. KRAS mutation status was determined by prospective local testing using next generation sequencing (NGS) or polymerase chain reaction of tumor tissue specimens. Patients were excluded if they were candidates for debulking surgery, were on treatment with warfarin, had an active skin disorder requiring systemic therapy within the past year, or had an ocular disorder (including a history of retinal pathology, an active or chronic visually significant corneal disorder, or a history of glaucoma).

Patients received AVMAPKI 3.2 mg orally twice weekly for the first 3 weeks out of a 4-week cycle and FAKZYNJA 200 mg orally twice daily for the first 3 weeks out of a 4-week cycle until disease progression or unacceptable toxicity. The major efficacy outcome measure was overall response rate (ORR) assessed by blinded independent review committee (BIRC) according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. An additional efficacy outcome measure was duration of response (DoR). Tumor response assessments occurred every 8 weeks for the first 72 weeks and every 12 weeks thereafter.

The median age was 60 years (range: 29 to 87); 75% were White, 3.5% were Asian, 3.5% were Black or African American, and 18% did not have race reported; 3.5% of patients were Hispanic or Latino; 72% had an ECOG PS of 0 and 28% had ECOG PS of 1. The KRAS mutations identified by local testing were G12V (53%), G12D (35%), Q61H (3.5%), G12C (1.8%), G12R (1.8%), A146V (1.8%), and mutations not otherwise specified at G12x (1.8%) and on codon 12/13 (1.8%). Fourteen percent of patients had received 1 prior line of systemic therapy, 25% of patients had received 2 prior lines, 18% had received 3 prior lines and 40% had received more than 3 prior lines of systemic therapy. All patients had received prior platinum-based chemotherapy, 84% received prior hormonal therapy (as maintenance or treatment), 40% received prior bevacizumab and 21% received a prior MEK inhibitor.

Efficacy results are presented in Table 5.
