4. CLINICAL PARTICULARS
4.1 Therapeutic indications
Jaypirca as monotherapy is indicated for the treatment of adult patients with relapsed or refractorymantle cell lymphoma (MCL) who have been previously treated with a Bruton’s tyrosine kinase(BTK) inhibitor.
Jaypirca as monotherapy is indicated for the treatment of adult patients with relapsed or refractorychronic lymphocytic leukaemia (CLL) who have been previously treated with a BTK inhibitor.
4.2 Posology and method of administration
Jaypirca therapy should be initiated and supervised by physicians experienced in the use of anticancertherapies.
PosologyThe recommended dose is 200 mg pirtobrutinib once daily (QD).
Jaypirca dosing should be interrupted until recovery to Grade 1 or baseline when the patientexperiences the following event:
* Grade 3 neutropenia with fever and/or infection
* Grade 4 neutropenia lasting ≥ 7 days
* Grade 3 thrombocytopenia with bleeding
* Grade 4 thrombocytopenia
* Grade 3 or 4 non-haematologic toxicity
Asymptomatic lymphocytosis is not regarded as an adverse reaction, and patients experiencing thisevent should continue taking Jaypirca.
In the clinical studies, adverse events in a limited number of patients were managed by dose reduction(see section 5.1).
Treatment should be continued until disease progression or unacceptable toxicity.
Missed doseIf more than 12 hours have passed after a patient has missed a dose, the patient should be instructed totake the next dose at its scheduled time; an additional dose should not be taken. If vomiting occurs, thepatient should not take an additional dose but continue with the next scheduled dose.
Special populationsElderlyNo dose adjustment is required based on age (see section 5.2).
Renal impairmentNo dose adjustment is required for patients with mild, moderate or severe renal impairment. There areno data in patients on dialysis (see section 5.2).
Hepatic impairmentNo dose adjustment is required for patients with mild, moderate, or severe hepatic impairment (seesection 5.2).
Paediatric populationThe safety and efficacy of Jaypirca in children and adolescents aged less than 18 years have not beenestablished. No data are available.
Method of administrationJaypirca is for oral use.
The tablet should be swallowed whole with a glass of water to ensure consistent performance (patientsshould not chew, crush, or split tablets before swallowing) and can be taken with or without food.
Patients should take the dose at approximately the same time every day.
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
InfectionsSerious infections, including fatal cases, have occurred in patients treated with Jaypirca. The mostfrequently reported Grade 3 or higher infections were pneumonia, COVID-19 pneumonia, COVID-19,and sepsis. Prophylactic antimicrobial therapy should be considered in patients who are at increasedrisk for opportunistic infections. Based on the grade of infection and whether it occurs withneutropenia, dose interruption may be required (see section 4.2).
HaemorrhageBleeding events, including fatal cases, have occurred in patients treated with Jaypirca, with andwithout thrombocytopenia. Major bleeding events of Grade 3 or higher, including gastrointestinalbleeding and intracranial haemorrhage have been observed. Patients should be monitored for signs andsymptoms of bleeding. Patients receiving anticoagulant or antiplatelet agents may be at increased riskof haemorrhage. The risks and benefits of anticoagulant or antiplatelet therapy should be consideredwhen co-administered with Jaypirca and consider additional monitoring for signs of bleeding. The useof Jaypirca has not been studied with warfarin or other vitamin K antagonists.
Dose interruption may be required for Grade 3 or 4 bleeding events (see section 4.2).
The benefit-risk of withholding Jaypirca for 3 to 5 days pre- and post-surgery should be considereddepending upon the type of surgery and risk of bleeding.
Cytopenias
Grade 3 or 4 cytopenias, including neutropenia, anaemia and thrombocytopenia occurred in patientstreated with Jaypirca. Complete blood counts should be monitored in patients during treatment asmedically indicated. Based on the grade of cytopenia, dose interruption may be required (seesection 4.2).
Atrial fibrillation/ flutter
Atrial fibrillation and atrial flutter have been observed in patients treated with Jaypirca, particularly inpatients with a history of atrial fibrillation and/or multiple cardiovascular comorbidities. Signs andsymptoms of atrial fibrillation and atrial flutter should be monitored in patients; obtain anelectrocardiogram as medically indicated. Based on the grade of atrial fibrillation/atrial flutter, doseinterruption may be required (see section 4.2).
Second primary malignancies
Second primary malignancies have commonly occurred in patients treated with Jaypirca, with the mostfrequent types being non-melanoma skin cancers. Patients should be monitored for the appearance ofskin cancers and advise protection from sun exposure.
Tumour lysis syndromeTumour lysis syndrome (TLS) has been reported rarely with Jaypirca therapy. Patients at high risk of
TLS are those with high tumour burden prior to treatment. Patients should be assessed for possible riskof TLS and closely monitored as clinically indicated.
Contraception in women of childbearing potential and males
Based on findings in animals and the genotoxicity of pirtobrutinib (see section 5.3), pirtobrutinib cancause foetal harm when administered to a pregnant woman. Women of childbearing potential shoulduse an effective method of contraception during treatment and for 5 weeks after the last dose of
Jaypirca. Men are advised to use an effective method of contraception and not father a child duringtreatment and for 3 months after the last dose of Jaypirca (see section 4.6).
LactosePatients with rare hereditary problems of galactose intolerance, total lactase deficiency orglucose-galactose malabsorption should not take this medicinal product.
SodiumThis medicinal product contains less than 1 mmol sodium (23 mg) per 200 mg daily dose, that is to sayessentially ‘sodium-free’.
4.5 Interaction with other medicinal products and other forms of interaction
Pirtobrutinib is primarily metabolised by CYP3A4, UGT1A8, and UGT1A9.
Effects of other medicinal products on the pharmacokinetics of pirtobrutinib
CYP3A inhibitorsIn a clinical study, itraconazole, a strong CYP3A4 inhibitor, increased the AUC of pirtobrutinib by48 % and did not change Cmax of pirtobrutinib. This increase in pirtobrutinib exposure is not clinicallymeaningful. Therefore, no dose adjustment of Jaypirca is necessary with CYP3A inhibitors.
CYP3A inducersIn a clinical study, rifampin, a strong CYP3A inducer, decreased the AUC and Cmax of pirtobrutinib by71 % and 42 %, respectively. Though this decrease in pirtobrutinib exposure is not expected to beclinically meaningful, if possible avoid strong CYP3A inducers (e.g. rifampicin, carbamazepine,phenytoin).
Coadministration with medicinal products that are proton pump inhibitors
No clinically significant differences in pirtobrutinib pharmacokinetics were observed whenadministered concomitantly with omeprazole, a proton pump inhibitor.
Effects of pirtobrutinib on the pharmacokinetics of other medicinal products (increase in plasmaconcentration)
CYP2C8 substrates
Pirtobrutinib is a moderate inhibitor of CYP2C8. Pirtobrutinib increased the AUC and Cmax ofrepaglinide (a substrate of CYP2C8) by 130 % and 98 %, respectively. Therefore, since pirtobrutinibcan increase the plasma concentrations of CYP2C8 substrates, caution is advised whenco-administering with CYP2C8 substrates (e.g. repaglinide, dasabuvir, selexipag, rosiglitazone,pioglitazone, and montelukast).
BCRP substratesPirtobrutinib is a moderate inhibitor of BCRP. Pirtobrutinib increased the AUC and Cmax ofrosuvastatin (a BCRP substrate) by 140 % and 146 %, respectively. Therefore, since pirtobrutinib canincrease the plasma concentrations of BCRP substrates, caution is advised when co-administering
BCRP substrates (e.g. rosuvastatin). If co-administration with narrow therapeutic index BCRPsubstrates (e.g. high dose methotrexate, mitoxantrone) cannot be avoided, close clinical monitoringshould be considered.
P-gp substratesPirtobrutinib is a weak inhibitor of P-gp. Pirtobrutinib increased the AUC and Cmax of digoxin (a P-gpsubstrate) by 35 % and 55 %, respectively. Therefore, pirtobrutinib can increase the plasmaconcentrations of P-gp substrates. If co-administration with narrow therapeutic index P-gp substrates(e.g dabigatran etexilate and digoxin) cannot be avoided, close clinical monitoring should beconsidered.
CYP2C19 substrates
Pirtobrutinib is a weak inhibitor of CYP2C19. Pirtobrutinib increased the AUC and Cmax ofomeprazole (a CYP2C19 substrate) by 56 % and 49 %, respectively. Therefore, pirtobrutinib canincrease the plasma concentrations of CYP2C19 substrates. If co-administration with narrowtherapeutic index CYP2C19 substrates (e.g. phenobarbital and mephenytoin) cannot be avoided, closeclinical monitoring should be considered.
CYP3A substratesPirtobrutinib is a weak inhibitor of CYP3A. Pirtobrutinib increased the AUC and Cmax of orallyadministered midazolam (sensitive CYP3A substrate) by 70 % and 58 %, respectively. Pirtobrutinibdid not have a clinically meaningful effect on the exposure of intravenously administered midazolam.
Therefore, pirtobrutinib can increase the plasma concentrations of CYP3A substrates. Ifco-administration with narrow therapeutic index CYP3A substrates (e.g alfentanil, midazolam,tacrolimus) cannot be avoided, close clinical monitoring should be considered.
4.6 Fertility, pregnancy and lactation
Women of childbearing potential/Contraception in males and femalesBased on findings in animals and the genotoxicity of pirtobrutinib (see section 5.3), pirtobrutinib cancause foetal harm when administered to a pregnant woman. Women of childbearing potential shoulduse an effective method of contraception during treatment and for 5 weeks after the last dose of
Jaypirca. Men are advised to use an effective method of contraception and not father a child duringtreatment and for 3 months after the last dose of Jayprica (see section 4.4).
PregnancyThere are no data from the use of Jaypirca in pregnant women. Studies in animals have shownreproductive toxicity (see section 5.3). Jaypirca should not be used during pregnancy.
Breast-feedingIt is unknown whether pirtobrutinib is excreted in human milk. A risk to the suckling child cannot beexcluded. Breast-feeding should be discontinued during treatment with Jaypirca and for one week afterthe last dose of Jaypirca.
FertilityThere are no data on the effect of pirtobrutinib on human fertility.
4.7 Effects on ability to drive and use machines
Jaypirca has a minor influence on the ability to drive and use machines. Fatigue, dizziness, andasthenia have been reported in some patients during treatment with Jaypirca and should be consideredwhen assessing a patient’s ability to drive or operate machines.

5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antineoplastic agents, protein kinase inhibitors, ATC code: L01EL05
Mechanism of actionPirtobrutinib is a reversible, noncovalent inhibitor of BTK. BTK is a signalling protein of the B-cellantigen receptor (BCR) and cytokine receptor pathways. In B-cells, BTK signalling results inactivation of pathways necessary for B-cell proliferation, trafficking, chemotaxis, and adhesion.
Pirtobrutinib binds to wild type BTK as well as BTK harboring C481 mutations leading to inhibitionof BTK kinase activity.
Pharmacodynamic effectsCardiac electrophysiologyThe effect of a single 900 mg dose of pirtobrutinib on the corrected QT (QTc) interval was evaluatedin a study with placebo and positive controls in 30 healthy subjects. The selected dose is equivalent toapproximately 2 times higher than the concentrations achieved at steady state at the recommendeddosage of 200 mg once daily. Pirtobrutinib had no clinically meaningful effect on the change in QTcorrected for heart rate using Fridericia’s formula (QTcF) interval (i.e., > 10 ms) and there was norelationship between pirtobrutinib exposure and change in QTc interval.
Clinical efficacy and safetyMantle Cell Lymphoma
The efficacy of Jaypirca was evaluated in adult patients with MCL in a phase 1/2 multicenter, openlabel, single arm clinical study: Study 18001 (BRUIN). The study included two parts: a phase 1 doseescalation, in which the dose range of monotherapy pirtobrutinib of 25 mg to 300 mg once daily wasinvestigated, and a phase 2 dose expansion. The primary objective of the phase 1 portion was todetermine the recommended phase 2 dose of pirtobrutinib, which was found to be 200 mg once daily,with a maximum tolerated dose not being established. The primary objective of the phase 2 part was toassess the anti-tumor activity of pirtobrutinib based on overall response rate as assessed by anindependent review committee. Patients received Jaypirca orally daily until disease progression orunacceptable toxicity.
Study 18001 enrolled and treated a total of 164 patients with a diagnosis of MCL and the primaryanalysis set (PAS) for the assessment of efficacy was based on the first 90 patients with MCL enrolledwho had no known central nervous system (CNS) involvement, were treated with a prior BTKinhibitor, had received one or more doses of Jaypirca and had at least 1 site of radiographicallyassessable disease. The median age was 70 years (range: 46 to 87 years), 80 % were male, 84.4 %were White, 67.8 % had a baseline Eastern Cooperative Oncology Group (ECOG) performance statusof 0 and 31.1 % had ECOG performance status of 1. Patients had a median number of 3 prior lines oftherapy (range: 1 to 8), with the reason for discontinuation from the most recent prior BTK inhibitortherapy being progression in 81.1 % of patients and intolerance in 13.3 % of patients. 95.6 % ofpatients received prior anti-CD20 therapy, 87.8 % chemotherapy, 18.9 % autologous stem celltransplantation, pct. 4.4 % allogenic stem cell transplantation, 15.6 % prior BCL2 inhibitor and 4.4 %received prior chimeric antigen receptor-modified T cells (CAR-T) therapy. 38.9 % patients hadextranodal involvement and 26.7 % had tumour bulk greater than or equal to 5 cm. The simplified
MCL International Prognostic Index (sMIPI) score was low in 22.2 %, intermediate in 55.6 % andhigh in 22.2 % of patients.
Of the 164 patients with MCL enrolled in Study 18001, 9 patients had a dose reduction, including6 responders that were able to remain on therapy and maintain a durable response following dosereductions to 150 mg QD (3), 100 mg QD (2), and 50 mg QD (1).
The efficacy of Jaypirca was based on a response as assessed using 2014 Lugano criteria for malignantlymphoma. Efficacy results for patients that received at least one prior BTK inhibitor and included inthe PAS are summarised in Table 2. For the 90 patients in the PAS, 79 received at least 1 dose of200 mg QD. Of these 79 patients, 77 started at 200 mg QD, 1 dose escalated from a lower dose and1 dose reduced from a higher dose. The median time on treatment was 5.24 months (range: 0.2 to39.6 months). Among the 51 responders, the median time to response was 1.84 months (range: 1.0 to7.5 months).
While subgroup analyses represent a limited number of patients, clinically meaningful efficacy resultswere observed across important subgroups, including patients that discontinued prior BTK inhibitortherapy due to intolerance or progression and irrespective of number and type of prior therapies.

Chronic Lymphocytic Leukaemia
The efficacy of Jaypirca in patients with BTK-inhibitor pretreated CLL was evaluated in arandomised, multicentre, international, open-label, actively-controlled trial (BRUIN CLL-321,
Study 20020). The trial enrolled 238 patients with CLL/SLL who were previously treated with a BTKinhibitor. Patients were randomised in a 1:1 ratio to receive either Jaypirca given orally once daily at adose of 200 mg until disease progression or unacceptable toxicity, or Investigator’s choice:
* Idelalisib plus a rituximab product (IR): Idelalisib 150 mg orally twice daily until diseaseprogression or unacceptable toxicity, in combination with 8 infusions of a rituximab product(375 mg/m2 intravenously on Day 1 of Cycle 1, followed by 500 mg/m2 every 2 weeks for4 doses and then every 4 weeks for 3 doses), with a 28-day cycle length.
* Bendamustine plus a rituximab product (BR): Bendamustine 70 mg/m2 intravenously (Day 1and 2 of each 28-day cycle), in combination with a rituximab product (375 mg/m2intravenously on Day 1 of Cycle 1, then 500 mg/m2 on Day 1 of subsequent cycles), for up to6 cycles.
Randomisation was stratified by 17p deletion status (yes/no) and receipt of prior venetoclax treatment(yes/no). Of the 238 patients total, 119 were assigned to Jaypirca monotherapy, 82 to IR and 37 to BR.
After confirmed disease progression, patients randomised to IR or BR had the option to cross over to
Jaypirca monotherapy. Baseline characteristics were similar between treatment arms. Overall, themedian age was 67 years (range: 42 to 90 years), 70 % were male and 81 % were White. Baseline
ECOG performance status was 0 or 1 in 93% of patients and 44% of patients had Rai stage III or IVdisease. Among those patients with central testing available, 57 % (101 of 176 patients) had 17pdeletion and/or TP53 mutation, 86 % (164 of 190 patients) had unmutated IGHV, and 65 % (97 of149) had complex karyotype.
Patients received a median number of 3 prior lines of therapy (range: 1 to 13) with 57 % having atleast 3 prior therapies and 51 % having had prior BCL2-inhibitor therapy. The most common prior
BTK inhibitors received were ibrutinib (87 %), acalabrutinib (16 %), and zanubrutinib (7 %). 70 % ofpatients discontinued the most recent BTK inhibitor for refractory or progressive disease, 15 %discontinued for toxicity, and 15 % discontinued for other reasons.
Efficacy was based on progression-free survival (PFS) of pirtobrutinib monotherapy versusinvestigator’s choice arm as assessed by an Independent Review Committee (IRC). The study met itsprimary endpoint at the prespecified time of final analysis for IRC-assessed PFS (29 Aug 2023 cut-off). At an updated analysis (29 Aug 2024 cut-off) with a median follow-up of 19.4 months (range0.03 to 33.3 months) for pirtobrutinib and 17.7 months (range 0.03 to 27.9 months) for theinvestigator’s choice arm, improved IRC-assessed PFS was observed with pirtobrutinib compared tothe investigator’s choice arm, consistent with the primary analysis. Clinically meaningful efficacyresults in favour of pirtobrutinib were observed across important subgroups, including patients whodiscontinued prior BTK inhibitor therapy due to intolerance or progression and irrespective of numberand type of prior therapies. Efficacy results are presented in Table 3. The Kaplan-Meier curve for PFSis shown in Figure 1.

5.2 Pharmacokinetic properties
The pharmacokinetics of pirtobrutinib were characterized in healthy subjects and in patients withcancer. Doses ranged from 25 mg to 300 mg once daily (0.125 to 1.5 times the recommended dosageof 200 mg once daily), up to single doses of 900 mg. Increases in plasma exposure wereapproximately dose proportional. Steady state was achieved within 5 days of once daily dosing, and incancer patients the mean [coefficient of variation (CV %)] accumulation ratio after administration of200 mg once daily was 1.63 (26.7 %) based on AUC. Three patient factors were attributed to changesin pirtobrutinib PK: body weight, serum albumin, and absolute eGFR. An increase in body weightfrom 70 kg to 120 kg is predicted to increase pirtobrutinib clearance by 24 %; a decrease in absoluteeGFR from 90 mL/min to 30 mL/min is predicted to reduce pirtobrutinib clearance by 16 %; and adecrease in serum albumin from 40 g/L to 30 g/L is predicted to increase pirtobrutinib clearance by21 %. These factors alone are unlikely to result in meaningful changes to pirtobrutinib PK and no doseadjustments are recommended.
The mean (CV %) steady-state AUC and Cmax were 92 600 h*ng/mL (39 %) and 6 500 ng/mL (25 %),respectively, at the recommended dosage of 200 mg once daily in cancer patients.
At the recommended dosage, pirtobrutinib achieves pharmacokinetic exposures that can exceed the
BTK IC96 at trough and thus deliver tonic BTK target inhibition throughout the once daily dosingperiod, regardless of the intrinsic rate of BTK turnover.
AbsorptionThe absolute bioavailability of pirtobrutinib after a single oral 200 mg dose is 85.5 % in healthysubjects. The median time to reach peak plasma concentration (tmax) is approximately 2 hours in bothcancer patients and healthy subjects. There is no pH dependency for absorption.
Effect of foodA high-fat, high-calorie meal administered to healthy subjects decreased the Cmax of pirtobrutinib by23 % and delayed tmax by 1 hour. There was no effect on pirtobrutinib AUC. Pirtobrutinib can be takenwith or without food.
DistributionThe mean apparent central volume of distribution of pirtobrutinib is 34.2 L in cancer patients. Theplasma protein binding is 96 % and was independent of concentration between 0.5 and 50 µM. Inplasma from healthy subjects and subjects with severe renal impairment the protein binding was 96 %.
Mean blood-to-plasma ratio is 0.79.
BiotransformationHepatic metabolism is the main route of clearance for pirtobrutinib. Pirtobrutinib is metabolised toseveral inactive metabolites by CYP3A4, UGT1A8 and UGT1A9. There was no clinically meaningfulimpact of CYP3A modulation on pirtobrutinib exposures.
Pirtobrutinib inhibits CYP2C8, CYP2C9 and CYP3A4 in vitro and minimally inhibits CYP1A2,
CYP2B6, CYP2C19 or CYP2D6 at 60 µM. In vitro pirtobrutinib induces CYP3A4, CYP3A5,
CYP2C19, and CYP2B6.
Pirtobrutinib minimally inhibits UGT1A1 in vitro with an IC50 = 18 µM.
Co-administration with transport substrates/inhibitors
In vitro studies indicated that pirtobrutinib is a substrate of P-gp and BCRP.
Pirtobrutinib is an in vitro inhibitor of P-gp and BCRP. Pirtobrutinib affected the PK of digoxin, a P-gp substrate, and rosuvastatin, a BCRP substrate, in clinical studies (see section 4.5).
EliminationThe mean apparent clearance of pirtobrutinib is 2.05 L/h with an effective half-life of approximately19.9 hours. Following a single radiolabeled dose of pirtobrutinib 200 mg to healthy subjects, 37 % ofthe dose was recovered in faeces (18 % unchanged) and 57 % in urine (10 % unchanged).
Special populationsAge, gender, race and body weight
Based on a population pharmacokinetic analysis in patients with cancer, age (range 22-95 years), race,gender, and body weight (range 35.7-152 kg) had no clinically meaningful effect on the exposure ofpirtobrutinib.
Renal impairmentIn a population PK analysis of cancer patients, patients with mild (eGFR 60 to < 90 ml/min) ormoderate renal impairment (eGFR 30 to < 60 ml/min), pirtobrutinib clearance was 16 % to 27 % lowercompared to clearance in patients with normal renal function, resulting in expected exposure of
AUC = 94 100 ng*h/mL and Cmax = 6 680 ng/mL in patients with mild renal impairment (16-19 %higher compared to patients with normal renal function) and AUC = 108 000 ng*h/mL and
Cmax = 7 360 ng/mL in patients with moderate renal impairment (28 to 36 % higher compared topatients with normal renal function).
In a clinical pharmacology study of otherwise healthy volunteers, apparent clearance was 35 % lowerin four participants with severe renal impairment (eGFR 15 to < 30 ml/min) compared toeight participants with normal renal function (eGFR ≥ 90 ml/min), resulting in exposures of
AUC0-inf = 115 000 ng*h/mL and Cmax = 2 980 ng/mL (62 % higher and 7 % lower, respectively,compared to normal renal function).
Patients with end-stage renal disease receiving dialysis were not studied (see section 4.2).
Hepatic impairmentThere were no clinically significant differences in the PK of pirtobrutinib for any degree of hepaticimpairment (by Child-Pugh A, B, and C or any total bilirubin and any AST). In a dedicated hepaticimpairment study mean AUC and Cmax of pirtobrutinib were similar between subjects with mildhepatic impairment (Child-Pugh A) and subjects with normal hepatic function. In subjects withmoderate hepatic impairment (Child-Pugh B) the AUC was 15 % lower compared to normal hepaticfunction and the Cmax was similar. In subjects with severe hepatic impairment (Child-Pugh C) the
AUC of pirtobrutinib was 21 % lower and mean Cmax was 24 % lower compared to subjects withnormal hepatic function. The fraction unbound (fu) for pirtobrutinib in subjects generally increased asthe severity of hepatic impairment increased. Therefore, after correcting pirtobrutinib PK exposureparameters with fu, there was no clinically significant difference observed in the unbound pirtobrutinib
PK exposure parameters (AUCu and Cmax,u) between subjects with any degree of hepatic impairmentand normal hepatic function.
Paediatric populationNo pharmacokinetic studies were performed with pirtobrutinib in patients under 18 years of age.
5.3 Preclinical safety data
In the repeat-dose studies decreased T-cell dependent antibody response in rats (at 0.69-fold humanexposure at the recommended dose of 200 mg based on AUC) and minimal to mild corneal lesions indogs (at 0.42-fold human exposure) were observed. Mild to moderate vascular necrosis andvascular/perivascular inflammation in large pulmonary blood vessels were observed only in rats.
These effects occurred at clinically relevant exposure levels.
Genotoxicity/CarcinogenicityPirtobrutinib was not mutagenic in a bacterial mutagenicity (Ames) assay. Pirtobrutinib was aneugenicin two in vitro micronucleus assays using human peripheral blood lymphocytes. Pirtobrutinib had noeffect in an in vivo rat bone marrow micronucleus assay at doses up to 2 000 mg/kg (single dose),which is approximately 11-fold higher exposure (considering unbound Cmax value in female animals)than human exposure at 200 mg.
Carcinogenicity studies have not been conducted with pirtobrutinib.
Embryotoxicity/ Teratogenicity
In animal reproduction studies, administration of pirtobrutinib to pregnant rats during organogenesisresulted in decreased foetal weight, embryo-foetal mortality, and foetal malformations at maternalexposures 3.0-fold human exposure at the recommended dose of 200 mg based on AUC.
Reproduction toxicity
No fertility studies have been conducted with pirtobrutinib. In repeat-dose toxicity studies of up to3 months duration, pirtobrutinib had no effect on male reproductive organs at 0.69-fold and 0.42-foldhuman exposure in rats and dogs, respectively, at the recommended dose of 200 mg based on AUC.
Pirtobrutinib had no effect on female reproductive organs at 4.0-fold and 0.42-fold human exposure inrats and dogs, respectively.
