Pharmacotherapeutic group: Ophthalmologicals, antineovascularisation agents, ATC code: S01LA09
Mechanism of actionFaricimab is a humanised bispecific immunoglobulin G1 (IgG1) antibody that acts through inhibitionof two distinct pathways by neutralisation of both angiopoietin-2 (Ang-2) and vascular endothelialgrowth factor A (VEGF-A).
Ang-2 causes vascular instability by promoting endothelial destabilisation, pericyte loss, andpathological angiogenesis, thus potentiating vascular leakage and inflammation. It also sensitisesblood vessels to the activity of VEGF-A resulting in further vascular destabilisation. Ang-2 and
VEGF-A synergistically increase vascular permeability and stimulate neovascularisation.
By dual inhibition of Ang-2 and VEGF-A, faricimab reduces vascular permeability and inflammation,inhibits pathological angiogenesis and restores vascular stability.
Pharmacodynamic effectsA suppression from baseline of median ocular free Ang-2 and free VEGF-A concentrations wasobserved from day 7 onwards in the six Phase III studies described hereafter.
nAMDIn TENAYA and LUCERNE, objective, pre-specified visual and anatomic criteria, as well as treatingphysician clinical assessment, were used to guide treatment decisions at the disease activityassessment time points (week 20 and week 24).
The mean central subfield thickness (CST) reduction from baseline at the primary endpoint visits(averaged at weeks 40-48) was comparable to those observed with aflibercept, with -137 µmand -137 µm in patients treated with faricimab dosed up to every 16 weeks (Q16W) as comparedto -129 µm and -131 µm with aflibercept, in TENAYA and LUCERNE, respectively. These mean
CST reductions were maintained through year 2.
At week 48, in both studies there was a comparable effect of faricimab and aflibercept on thereduction of intraretinal fluid (IRF), subretinal fluid (SRF), and PED. These effects in IRF, SRF, and
PED were maintained at year 2. There were also comparable changes in total CNV lesion area andreductions in CNV leakage area from baseline for patients in the faricimab and aflibercept treatmentarms.
DMEIn YOSEMITE and RHINE, anatomic parameters related to macular oedema were part of the diseaseactivity assessments guiding treatment decisions.
The mean CST reduction from baseline at the primary endpoint visits (averaged at weeks 48-56) wasnumerically greater than those observed with aflibercept, with -207 µm and -197 µm in patientstreated with faricimab Q8W and faricimab up to Q16W adjustable dosing as compared to -170 µm inaflibercept Q8W patients in YOSEMITE; results were 196 µm, 188 µm, and 170 µm, respectively in
RHINE. Consistent reductions in CST were observed through year 2. Greater proportions of patientsin both faricimab arms achieved absence of IRF and absence of DME (defined as reaching CST below325 µm) over time through year 2 as compared to aflibercept in both studies.
RVO
In Phase III studies in patients with branch retinal vein occlusion (BRVO; BALATON) andcentral/hemiretinal vein occlusion (C/HRVO; COMINO), reductions in mean CST were observedfrom baseline to week 24 with faricimab Q4W and were comparable to those seen with aflibercept
Q4W. The mean CST reduction from baseline to week 24 was 311.4 μm for faricimab Q4W versus304.4 μm for aflibercept Q4W, in BALATON, and 461.6 μm versus 448.8 μm in COMINO forfaricimab and aflibercept, respectively. CST reductions were maintained through week 72 whenpatients moved to a faricimab up to Q16W adjustable dosing regimen.
Comparable proportions of patients in both faricimab Q4W and aflibercept Q4W arms achievedabsence of IRF, absence of SRF, and absence of macular edema (defined as reaching CST below325 µm) over time through week 24, in both studies. These results were maintained through week 72when patients moved to a faricimab up to Q16W adjustable dosing regimen.
Clinical efficacy and safetynAMD
The safety and efficacy of faricimab were assessed in two randomised, multi-centre, double-masked,active comparator-controlled, 2-year non-inferiority studies in patients with nAMD, TENAYA and
LUCERNE. A total of 1 329 patients were enrolled, with 1 135 (85%) patients completing the studiesthrough week 112. A total of 1 326 patients received at least one dose (664 with faricimab). Patientages ranged from 50 to 99 years with a mean [standard deviation; SD] of 75.9 [8.6] years.
In both studies, patients were randomised in a 1:1 ratio to one of two treatment arms:
* Faricimab 6 mg up to Q16W after four initial monthly doses
* Aflibercept 2 mg Q8W after three initial monthly doses
After the first four monthly doses (weeks 0, 4, 8, and 12) patients randomised to the faricimab armreceived Q16W, every 12 weeks (Q12W) or Q8W dosing based on an assessment of disease activity atweeks 20 and 24. Disease activity was assessed using objective pre-specified visual (BCVA) andanatomic (CST) criteria, as well as treating physician clinical assessment of the presence of macularhaemorrhage or nAMD disease activity requiring treatment (week 24 only). Patients remained on thesefixed dosing intervals until week 60 without supplemental therapy. From week 60 onwards, patients inthe faricimab arm moved to an adjustable dosing regimen, where their treatment interval could bemodified by up to 4 week interval extensions (up to Q16W) or reduced by up to 8 week intervals (upto Q8W) based on an automated objective assessment of pre-specified visual (BCVA) and anatomic(CST and macular haemorrhage) disease activity criteria. Patients in the aflibercept arm remained on
Q8W dosing throughout the study period. Both studies were 112 weeks in duration.
ResultsBoth studies showed efficacy in the primary endpoint, defined as the mean change from baseline in
BCVA when averaged over the week 40, 44, and 48 visits and measured by the Early Treatment
Diabetic Retinopathy Study (ETDRS) letter score (Table 2 and Table 3). In both studies, faricimab upto Q16W treated patients had a non-inferior mean change from baseline in BCVA, as the patientstreated with aflibercept Q8W at year 1, and these vision gains were maintained through week 112.
Improvements from baseline BCVA at week 112 are shown in Figure 1.
The proportion of patients on each of the different treatment intervals at week 112 in TENAYA and
LUCERNE, respectively was:
* Q16W: 59% and 67%
* Q12W: 15% and 14%
* Q8W: 26% and 19%

Figure 1: Mean change in visual acuity from baseline to year 2 (week 112); combined data from
TENAYA and LUCERNE studies
In both TENAYA and LUCERNE, improvements from baseline in BCVA and CST at week 60 werecomparable across the two treatment arms and consistent with those seen at week 48.
At week 60, 46% of patients in both TENAYA and LUCERNE were on a Q16W interval. Of these,69% of patients in both studies maintained Q16W through week 112 without interval reduction.
At week 60, 80% and 78% of patients in TENAYA and LUCERNE, respectively, were on a ≥ Q12Winterval (Q16W or Q12W). Of these, 67% and 75% of patients, respectively, maintained a ≥ Q12Winterval through week 112 without an interval reduction below Q12W.
At week 60, 33% of patients in both TENAYA and LUCERNE were on a Q12W interval. Of these,3.2% and 0% of patients in TENAYA and LUCERNE, respectively, maintained Q12W throughweek 112.
At week 60, 20% and 22% of patients in TENAYA and LUCERNE, respectively, were on a Q8Winterval. Of these, 34% and 30% of patients in TENAYA and LUCERNE, respectively, maintained
Q8W therapy through week 112.
Efficacy results in all evaluable subgroups (e.g. age, gender, race, baseline visual acuity, lesion type,lesion size) in each study, and in the pooled analysis, were consistent with the results in the overallpopulations.
Across studies, faricimab up to Q16W showed improvement in pre-specified efficacy endpoint ofmean change from baseline to week 48 in the National Eye Institute Visual Function Questionnaire(NEI VFQ-25) composite score that was comparable to aflibercept Q8W, and exceeded the thresholdof 4 points. The magnitude of these changes corresponds to a 15-letter gain in BCVA.
The incidence of ocular adverse events in the study eye was 53.9% and 52.1% and non-ocular adverseevents was 73.3% and 74.3%, through week 112 in the faricimab and aflibercept arms, respectively(see section 4.4 and 4.8).
DMEThe safety and efficacy of faricimab were assessed in two randomised, multi-centre, double-masked,active comparator-controlled 2-year non-inferiority studies (YOSEMITE and RHINE) in patients with
DME. A total of 1 891 patients were enrolled in the two studies with 1 622 (86%) patients completingthe studies through week 100. A total of 1 887 patients were treated with at least one dose throughweek 56 (1 262 with faricimab). Patient ages ranged from 24 to 91 with a mean [SD] of62.2 [9.9] years. The overall population included both anti-VEGF naive patients (78%) and patientswho had been previously treated with a VEGF inhibitor prior to study participation (22%). In bothstudies, patients were randomised in a 1:1:1 ratio to one of the three treatment regimens:
* Faricimab 6 mg Q8W after the first 6 monthly doses.
* Faricimab 6 mg up to Q16W adjustable dosing administered in 4, 8, 12 or 16-week intervalsafter the first 4 monthly doses.
* Aflibercept 2 mg Q8W after the first 5 monthly doses.
In the Q16W adjustable dosing arm, the dosing followed a standardised treat-and-extend approach.
The interval could be increased in 4-week increments or decreased in 4- or 8-week increments basedon anatomic and/or visual outcomes, using data obtained only at study drug dosing visits.
ResultsBoth studies showed efficacy in the primary endpoint, defined as the mean change from baseline in
BCVA at year 1 (average of the week 48, 52, and 56 visits), measured by the ETDRS Letter Score. Inboth studies, faricimab up to Q16W treated patients had a non-inferior mean change from baseline in
BCVA, as the patients treated with aflibercept Q8W at year 1, and these vision gains were maintainedthrough year 2.
After 4 initial monthly doses, the patients in the faricimab up to Q16W adjustable dosing arm couldhave received between the minimum of 6 and the maximum of 21 total injections through week 96. Atweek 52, 74% and 71% of patients in the faricimab up to Q16W adjustable dosing arm achieved a
Q16W or Q12W dosing interval in YOSEMITE and RHINE, respectively (53% and 51% on Q16W,21% and 20% on Q12W). Of these patients, 75% and 84% maintained ≥ Q12W dosing without aninterval reduction below Q12W through week 96; of the patients on Q16W at week 52, 70% and 82%of patients maintained Q16W dosing without an interval reduction through week 96 in YOSEMITEand RHINE, respectively. At week 96, 78% of patients in the faricimab up to Q16W adjustable dosingarm achieved a Q16W or Q12W dosing interval in both studies (60% and 64% on Q16W, 18% and14% on Q12W). 4% and 6% of patients were extended to Q8W and stayed on ≤ Q8W dosing intervalsthrough week 96; 3% and 5% received only Q4W dosing in YOSEMITE and RHINE throughweek 96, respectively.
Detailed results from the analyses of YOSEMITE and RHINE studies are listed in Table 4, Table 5,and Figure 2 below.

Figure 2: Mean change in visual acuity from baseline to year 2 (week 100); combined data from
YOSEMITE and RHINE studies
Efficacy results in patients who were anti-VEGF treatment naive prior to study participation and in allthe other evaluable subgroups (e.g. by age, gender, race, baseline HbA1c, baseline visual acuity) ineach study were consistent with the results in the overall populations.
Across studies, faricimab Q8W and up to Q16W adjustable dosing showed improvements in the pre-specified efficacy endpoint of mean change from baseline to week 52 in the NEI VFQ-25 compositescore that was comparable to aflibercept Q8W and exceeded the threshold of 4 points. Faricimab Q8Wand up to Q16W adjustable dosing also demonstrated clinically meaningful improvements in the pre-specified efficacy endpoint of change from baseline to week 52 in the NEI VFQ-25 near activities,distance activities, and driving scores, that were comparable to aflibercept Q8W. The magnitude ofthese changes corresponds to a 15-letter gain in BCVA. Comparable proportions of patients treatedwith faricimab Q8W, faricimab up to Q16W adjustable dosing, and aflibercept Q8W experienced aclinically meaningful improvement of ≥ 4-points from baseline to week 52 in the NEI VFQ-25composite score, a pre-specified efficacy endpoint. These results were maintained at week 100.
An additional key efficacy outcome in DME studies was the change in the Early Treatment Diabetic
Retinopathy Study Diabetic Retinopathy Severity Scale (ETDRS-DRSS) from baseline to week 52. Ofthe 1 891 patients enrolled in Studies YOSEMITE and RHINE, 708 and 720 patients were evaluablefor DR endpoints, respectively.
The ETDRS-DRSS scores ranged from 10 to 71 at baseline.
The majority of patients, approximately 60%, had moderate to severe non-proliferative DR (DRSS43/47/53) at baseline.
The proportion of patients who achieved ≥ 2-step and ≥ 3-step improvement from baseline in ETDRS-
DRSS at week 52 and at week 96 are shown in Table 6 and Table 7 below.

Treatment effects in evaluable subgroups (e.g. by previous anti-VEGF treatment, age, gender, race,baseline HbA1c, and baseline visual acuity) in each study were generally consistent with the results inthe overall population.
Treatment effects in subgroups by DR severity at baseline were different and showed the greatest ≥ 2-step DRSS improvements among patients with moderately severe and severe non-proliferative DRwith approximately 90% of patients achieving improvements consistently across all treatment arms inboth studies.
The incidence of ocular adverse events in the study eye was 49.7%, 49.2%, and 45.4% and non-ocularadverse events was 73.0%, 74.2%, and 75.7% through week 100, in the faricimab Q8W, faricimab upto Q16W, and aflibercept Q8W arms, respectively (see section 4.4 and 4.8).

The safety and efficacy of faricimab were assessed in two randomised, multi-centre, double-masked,72-week long studies in patients with macular oedema secondary to BRVO (BALATON) or
CRVO/HRVO (COMINO). Active comparator-controlled data are available through month 6.
A total of 1 282 patients (553 in BALATON and 729 in COMINO) were enrolled in the two studies,with 1 276 patients treated with at least one dose through week 24 (641 with faricimab). Patient agesranged from 28 to 93 with a mean [SD] of 64 [10.7] years, and 22 to 100 with a mean [SD] of65 [13.2] years in BALATON and COMINO, respectively.
A total of 489 out of 553 patients randomised in BALATON completed the study at week 72;263 patients initially randomised to faricimab (‘prior faricimab’) and 267 patients initially randomisedto aflibercept (‘prior aflibercept’) received at least one dose of faricimab during the faricimabadjustable dosing phase.
A total of 656 out of 729 patients randomised in COMINO completed the study at week 72; 353 priorfaricimab and 342 prior aflibercept patients received at least one dose of faricimab during thefaricimab adjustable dosing phase.
In both studies, patients were randomised in a 1:1 ratio to one of two treatment arms until week 24:
* Faricimab 6 mg Q4W for 6 consecutive monthly doses
* Aflibercept 2 mg Q4W for 6 consecutive monthly doses
After 6 initial monthly doses, patients initially randomised to the aflibercept 2 mg arm moved tofaricimab 6 mg, and could have received faricimab 6 mg up to Q16W adjustable dosing, where thedosing interval could be increased in 4-week increments or decreased by 4-, 8- or 12-weeks based onan automated objective assessment of pre-specified visual and anatomic disease activity criteria.
ResultsBoth studies showed efficacy in the primary endpoint, defined as the change from baseline in BCVAat week 24, measured by the ETDRS Letter Score. In both studies, faricimab Q4W treated patients hada non-inferior mean change from baseline in BCVA, compared to patients treated with aflibercept
Q4W, and these vision gains were maintained through week 72 when patients moved to a faricimab upto Q16W adjustable dosing regimen.
Between week 24 and week 68, 81.5% and 74.0% of the patients receiving faricimab up to Q16Wadjustable dosing regimen achieved a ≥ Q12W (Q16W or Q12W) dosing interval in BALATON and
COMINO, respectively. Of these patients, 72.1% and 61.6% completed at least one cycle of Q12Wand maintained ≥ Q12W dosing without an interval reduction below Q12W through week 68 in
BALATON and COMINO, respectively; 1.2% and 2.5% of the patients received only Q4W dosingthrough week 68 in BALATON and COMINO, respectively.
Across studies, at week 24 patients in the faricimab Q4W arm showed improvement in the pre-specified efficacy endpoint of change from baseline to week 24 in the NEI VFQ-25 composite scorethat was comparable to aflibercept Q4W. Faricimab Q4W also demonstrated improvement in the pre-specified efficacy endpoint of change from baseline to week 24 in the NEI VFQ-25 near activities anddistance activities, that were comparable to aflibercept Q4W. These results were maintained throughweek 72 when all patients were on faricimab up to Q16W adjustable dosing regimen.
