Co-administration of LUMYKRAS with acid-reducing agents

Co-administration of proton pump inhibitors (PPIs) or H2 receptor antagonists with LUMYKRAS is not recommended. If treatment with an acid-reducing agent is required a local antacid may be used, LUMYKRAS should be taken either 4 hours before or 10 hours after administration of a local antacid (see section 4.5).

Special populations

Elderly

In clinical studies, no overall differences in safety or efficacy were observed between elderly patients (≥ 65 years old) and younger patients. No dose adjustment is recommended in elderly patients (see section 5.2).

Hepatic impairment

No dose adjustment is recommended for patients with mild hepatic impairment (AST or ALT < 2.5 × ULN or total bilirubin < 1.5 × ULN). LUMYKRAS has not been studied in patients with moderate or severe hepatic impairment (see section 5.2).

Renal impairment

Based on population pharmacokinetic analysis, no dose adjustment is recommended for patients with mild renal impairment (creatine clearance, CrCL, ≥ 60 mL/min). LUMYKRAS has not been studied in patients with moderate or severe renal impairment (CrCL < 60 mL/min) (see section 5.2).

Paediatric population

The safety and efficacy of LUMYKRAS in children and adolescents aged less than 18 years have not been established. No data are available.

Method of administration

LUMYKRAS is for oral use. The tablets should normally be swallowed whole, unless the patient has difficulty swallowing solids, in which case the following instruction should be followed.

Administration to patients who have difficulty swallowing solids

Patients should disperse tablets in 120 mL of non-carbonated, room-temperature water without crushing. Other liquids must not be used. Patients should stir until tablets are dispersed into small pieces (the tablet will not completely dissolve) and drink immediately. The appearance of the mixture may range from pale to bright yellow. The container must be rinsed with an additional 120 mL of water, which should be drunk immediately. If it is not drunk immediately, patients must stir again to ensure that the tablets are dispersed. The dispersion must be discarded if it is not drunk within 2 hours.

4.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

4.4 Special warnings and precautions for use

Hepatotoxicity

LUMYKRAS can cause hepatotoxicity, which may lead to drug-induced liver injury and hepatitis. Sotorasib has been associated with transient elevations of serum transaminases (ALT and AST) (see section 4.8). These elevations improved or resolved with dose modification or permanent discontinuation of treatment and did not result in any cases of liver failure or fatal cases in clinical studies. Cases of liver enzyme increase can be asymptomatic. Liver function tests (ALT, AST, and total bilirubin) must be monitored prior to the start of LUMYKRAS, every 3 weeks for the first 3 months of treatment, then once a month or as clinically indicated, with more frequent testing in patients who develop transaminase and/or bilirubin elevations. Based on the severity of the laboratory abnormalities, treatment with LUMYKRAS must be stopped until recovered to ≤ grade 1 or to baseline grade, and the dose must either be modified or permanently discontinue treatment as recommended (see section 4.2).

Interstitial Lung Disease (ILD)/Pneumonitis

ILD/pneumonitis occurred in patients treated with LUMYKRAS with prior exposure to immunotherapy or radiotherapy (see section 4.8). Monitor patients for new or worsening pulmonary symptoms indicative of ILD/pneumonitis (e.g., dyspnoea, cough, fever). Immediately withhold LUMYKRAS in patients with suspected ILD/pneumonitis and permanently discontinue LUMYKRAS if no other potential causes of ILD/pneumonitis are identified (see section 4.2)

Lactose intolerance

Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Sodium

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially 'sodium-free'.

4.5 Interaction with other medicinal products and other forms of interaction

Effects of other medicinal products on sotorasib

Acid-reducing agents

Co-administration of sotorasib with a PPI (omeprazole) or an H2 receptor antagonist (famotidine) led to a decrease in sotorasib concentrations.

Under fed conditions (standard-calorie moderate-fat meals), co-administration of multiple doses of omeprazole with a single dose of 960 mg sotorasib decreased sotorasib Cmax by 65% and AUC by 57%. Co-administration of a single dose of famotidine given 10 hours prior and 2 hours after a single dose of 960 mg sotorasib decreased sotorasib Cmax by 35% and AUC by 38%.

Under fasted conditions, co-administration of multiple doses of omeprazole with a single dose of 960 mg sotorasib decreased sotorasib Cmax by 57% and AUC by 42%.

Co-administration of PPIs and H2 receptor antagonists with LUMYKRAS is not recommended because the impact on sotorasib efficacy is unknown. If treatment with an acid-reducing agent is required, LUMYKRAS should be taken 4 hours before or 10 hours after administration of a local antacid (see section 4.2).

Strong CYP3A4 inducers

Co-administration of sotorasib with multiple doses of a strong CYP3A4 inducer (rifampicin) decreased sotorasib Cmax by 35% and AUC by 51%. Co-administration of strong CYP3A4 inducers with LUMYKRAS is not recommended because the impact on sotorasib efficacy is unknown.

Effect of sotorasib on other medicinal products

CYP3A4 substrates

Sotorasib is a moderate CYP3A4 inducer. Co-administration of sotorasib with CYP3A4 substrates led to a decrease in their plasma concentrations, which may reduce the efficacy of these substrates.

Co-administration of sotorasib with midazolam (a sensitive CYP3A4 substrate) decreased midazolam Cmax by 48% and AUC by 53%.

Avoid co-administration of LUMYKRAS with CYP3A4 substrates with narrow therapeutic indices. If co-administration cannot be avoided, adjust the CYP3A4 substrate dosage in accordance with the current summary of product characteristics.

Transporter systems

P-glycoprotein (P-gp) Substrates

Coadministration of LUMYKRAS with digoxin (a P-gp substrate) increased digoxin Cmax by 91% and AUC by 21%.

Avoid coadministration of LUMYKRAS with P-gp substrates, for which minimal concentration changes may lead to serious toxicities. If coadministration cannot be avoided, decrease the P-gp substrate dosage in accordance with its Prescribing Information.

In vitro data indicated that sotorasib may have the potential to inhibit Breast Cancer Resistance Protein (BCRP); the clinical relevance of these findings is unknown.

4.6 Fertility, pregnancy and lactation

Pregnancy

There are no data from the use of sotorasib in pregnant women. Studies in animals have shown reproductive toxicity (see section 5.3). Patients must be informed of the potential hazards to the foetus if LUMYKRAS is used during pregnancy, or if the patient becomes pregnant while taking LUMYKRAS.

Breast-feeding

It is unknown if sotorasib or its metabolites are excreted in human milk. A risk to newborns/infants cannot be excluded. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from LUMYKRAS therapy taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman.

Fertility

There are no clinical studies to evaluate the effect of sotorasib on fertility.

4.7 Effects on ability to drive and use machines

LUMYKRAS has no or negligible influence on the ability to drive and use machines.

Description of selected adverse reactions

Hepatotoxicty

Among 359 patients who received LUMYKRAS in CodeBreaK 100, a total of 17% of patients who received LUMYKRAS had increased alanine aminotransferase (ALT)/increased aspartate aminotransferase (AST); 6% were Grade 3 and 0.6% were Grade 4. The median time to first onset of increased ALT/AST was 8 weeks (range: 0.3 to 42). Increased ALT/AST leading to dose interruption or reduction occurred in 7% of patients. LUMYKRAS was discontinued due to increased ALT/AST in 1.7% of patients. In addition to dose interruption or reduction, 5% of patients received corticosteroids for the treatment of hepatotoxicity.

Interstitial Lung Disease (ILD)/Pneumonitis

Among 359 patients who received LUMYKRAS in CodeBreaK 100, ILD/pneumonitis occurred in 0.8% of patients, all cases were Grade 3 or 4 at onset. The median time to first onset for ILD/pneumonitis was 2 weeks (range: 2 to 18 weeks). LUMYKRAS was discontinued due to ILD/pneumonitis in 0.6% of patients.

4.9 Overdose

There is no clinical experience with overdose with sotorasib. In the event of an overdose, the patient should be treated symptomatically, and supportive measures instituted as required.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Antineoplastic agents, ATC code: L01XX73

Mechanism of action

Sotorasib is a potent and highly selective KRASG12C (Kirsten rat sarcoma viral oncogene homolog) inhibitor, which covalently and irreversibly binds to the unique cysteine of KRASG12C. Inactivation of KRASG12C by sotorasib blocks tumour cell signalling and survival, inhibits cell growth, and promotes apoptosis selectively in tumours harbouring KRASG12C, an oncogenic driver of tumourigenesis across multiple cancer types. The potency and selectivity of sotorasib is enhanced through the unique binding to both the P2 pocket and the His95 surface groove, locking the protein in an inactive state that prevents downstream signalling, without affecting wild-type KRAS.

Sotorasib demonstrated in vitro and in vivo inhibition of KRASG12C with minimal detectable off-target activity against other cellular proteins and processes. Sotorasib impaired oncogenic signalling and tumour cell survival at clinically relevant exposures in numerous pre-clinical models expressing KRASG12C. Sotorasib also enhanced antigen presentation and inflammatory cytokine production only in tumour cells with KRASG12C. Sotorasib induced anti-tumour inflammatory responses and immunity, driving permanent and complete tumour regressions in immunocompetent mice implanted with KRASG12C expressing tumours.

Clinical efficacy and safety

LUMYKRAS for the treatment of previously treated KRAS G12C-mutated NSCLC (CodeBreaK 100)

The efficacy of LUMYKRAS was demonstrated in a single-arm, open-label, multicentre trial (CodeBreaK 100) that enrolled patients with locally advanced or metastatic KRAS G12C-mutated NSCLC who had disease progression after receiving prior therapy. Key eligibility criteria included progression on an immune checkpoint inhibitor and/or platinum-based chemotherapy, an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 or 1, and at least one measurable lesion as defined by Response Evaluation Criteria in Solid Tumours (RECIST v1.1). All patients were required to have KRAS G12C-mutated NSCLC prospectively identified in tumour samples using a validated test performed in a central laboratory.

A total of 126 patients were enrolled and treated with LUMYKRAS 960 mg once daily as monotherapy until disease progression or unacceptable toxicity; 124 patients had at least one measurable lesion at baseline as assessed by Blinded Independent Central Review (BICR) according to RECIST 1.1 and were included in the analysis for response-related efficacy outcomes. The median duration of treatment was 5.5 months (range: 0 to 15) with 48% of patients treated for ≥ 6 months and 33% of patients treated for ≥ 9 months.

The major efficacy outcome measures were objective response rate (ORR) and duration of response (DOR) as evaluated by a BICR according to RECIST v1.1. Additional efficacy outcome measures included disease control rate (DCR), time to response (TTR), progression-free survival (PFS), and overall survival (OS).

The baseline demographic and disease characteristics of the study population were: median age 64 years (range: 37 to 80); 50% Female; 82% White, 15% Asian, 2% Black; 70% ECOG PS 1; 96% had stage IV disease; 99% with non-squamous histology; 81% former smokers, 12% current smokers, 5% never smokers.

All patients received at least 1 prior line of systemic therapy for metastatic NSCLC; 43% received only 1 prior line of therapy, 35% received 2 prior lines of therapy, 22% received 3 prior lines of therapy, 91% received prior anti-PD-1/PD-L1 immunotherapy, 90% received prior platinum-based chemotherapy, 81% received both platinum-based chemotherapy and anti-PD-1/PD-L1. The sites of known extra-thoracic metastasis included 48% bone, 21% brain, and 21% liver.

Efficacy results are summarised in table 4. The ORR was 37% (95% CI: 29, 47). The patients with objective responses had DOR ranging from 1.2 to 11.1 months, and 43% were still on therapy with ongoing response after a median duration of follow-up of 9.6 months. The median TTR was 1.4 months (range: 1.2 to 10.1), with 70% of responses occurring within the first 7 weeks.

Cardiac electrophysiology

The effect of sotorasib on the QT interval was assessed in 156 patients administered sotorasib 960 mg once daily in clinical studies. Sotorasib did not prolong the QT interval to any clinically relevant extent. At peak concentrations, the mean change from baseline was less than 5 msec. No patients had a large mean increase in QTc (> 20 msec) in the study.

Paediatric population

The Medicines and Healthcare products Regulatory Agency has waived the obligation to submit the results of studies with LUMYKRAS in all subsets of the paediatric population in NSCLC (see section 4.2 for information on paediatric use).

This medicinal product has been authorised under a so-called 'conditional approval' scheme. This means that further evidence on this medicinal product is awaited.

The Medicines and Healthcare products Regulatory Agency will review new information on this medicinal product at least every year and this SmPC will be updated as necessary.

5.2 Pharmacokinetic properties

Absorption

Following an oral, single-dose administration, sotorasib was absorbed with median time to achieve peak concentration of 1 hour.

Effect of food

Following administration of sotorasib with a high-fat, high-calorie meal, there was no effect on Cmax, and AUC increased by 38% compared to administration under fasted conditions. Sotorasib can be administered with or without food.

Distribution

The mean volume of distribution at steady state of sotorasib was 211 L. In vitro, plasma protein binding of sotorasib was 89%.

Biotransformation

The main metabolic pathways of sotorasib were conjugation and oxidative metabolism.

Elimination

At 960 mg once daily, the steady state apparent clearance is 26.2 L/hr. The mean half-life is 5 hours. Steady state was reached within 22 days and remained stable. No accumulation with multiple dosing was observed. Sotorasib is primarily eliminated in faeces, with approximately 74% of the dose recovered in faeces and 6% (1% unchanged) recovered in urine.

Pharmacokinetics in special populations

No clinically meaningful differences in the pharmacokinetics of sotorasib were observed based on age, sex, race or ethnicity, body weight, line of therapy, ECOG PS, mild renal impairment (CrCL: ≥ 60 mL/min), or mild hepatic impairment (AST or ALT < 2.5 × ULN or total bilirubin < 1.5 × ULN). The effect of moderate to severe renal or hepatic impairment on sotorasib pharmacokinetics has not been studied.

5.3 Preclinical safety data

Mutagenicity

Sotorasib was not mutagenic in a bacterial mutagenicity (Ames) assay. Sotorasib was not genotoxic in the in vivo rat micronucleus and comet assays.

Carcinogenicity

Carcinogenicity studies have not been performed with sotorasib.

Reproductive toxicity

In rat and rabbit embryo-foetal development studies, oral sotorasib was not teratogenic.

In the rat, there were no effects on embryo-foetal development up to the highest dose tested (3.9 times higher than the exposure at the maximum recommended human dose [MRHD] of 960 mg based on area under the curve [AUC]).

In the rabbit, lower foetal body weights and a reduction in the number of ossified metacarpals in foetuses were observed only at the highest dose level tested (2.2 times higher than the exposure at the MRHD of 960 mg based on AUC), which was associated with maternal effects such as decreased body weight gain and food consumption during the dosing phase. Reduced ossification, as evidence of growth retardation associated with reduced foetal body weight, was interpreted as a non-specific effect in the presence of significant maternal toxicity.

Impairment of fertility

Fertility/early embryonic development studies were not conducted with sotorasib. There were no adverse effects on male or female reproductive organs in general toxicology studies conducted in dogs and rats.

General toxicology

In rats, renal toxicity including minimal to marked histologic tubular degeneration/necrosis and increased kidney weight, urea nitrogen, creatinine, and urinary biomarkers of renal tubular injury were present at doses resulting in exposures approximately ≥ 0.5 times the human AUC at the clinical dose of 960 mg. Increases in cysteine S-conjugate β-lyase pathway metabolism in the rat kidney compared to human may make rats more susceptible to renal toxicity than humans due to local formation of a putative sulphur-containing metabolite..

In the 3-month toxicology study in dogs, sotorasib induced findings in the liver (centrilobular hepatocellular hypertrophy), pituitary gland (hypertrophy of basophils), and thyroid gland (marked follicular cell atrophy, moderate to marked colloid depletion, and follicular cell hypertrophy) at exposures approximately 0.4 times the human exposure based on AUC at the clinical dose of 960 mg. These findings may be due to an adaptive response to hepatocellular enzyme induction and subsequent reduced thyroid hormone levels (i.e. secondary hypothyroidism).

Environmental risk assessment

Environmental risk assessment studies have shown that sotorasib has the potential to be persistent to the environment (see section 6.6). There is no potential for bioaccumulation or toxicity.
