Brief summary

CLGX818X2101 is a first-time in-human, phase I study to establish the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) of daily administered LGX818 (daily, twice daily and/or every-other-day), a RAF kinase inhibitor. Patients with locally advanced or metastatic melanoma harboring the BRAF V600 mutation (during dose escalation phase and expansion phase) and patients with metastatic colorectal cancer harboring the BRAF V600 mutation (during the expansion phase) will be enrolled. The study consists of a dose escalation part were cohorts of patients will receive escalating oral doses of LGX818, followed by a safety dose expansion part were patients will be treated with oral dose of LGX818 given at the MTD or RP2D.

Secondary

MeasureTime frameDescription
Progression Free Survival (PFS): Dose Escalation PhaseFrom start of study treatment until first documentation of PD or death due to any cause or censoring date (maximum of 556.1 weeks of treatment exposure)PFS was defined as time from date of first study treatment intake to date of first documented disease progression (PD) or death due to any cause. If a participant did not have an event, data censoring was done at the date of last adequate tumor assessment. PD was defined for target disease as at least a 20% increase in sum of longest diameters of all measured target lesions, taking as reference smallest sum on study (this included baseline sum if that was smallest on study), sum also demonstrated absolute increase of greater than or equal to (\>=) 5 mm, or appearance of \>=1 new lesions. For non-target disease: PD was defined as unequivocal progression of pre-existing lesions and if overall tumor burden increased sufficiently to merit discontinuation of therapy; appearance of any new unequivocal malignant lesion was also considered PD. Analysis was performed using Kaplan-Meier method.
PFS: Dose Expansion PhaseFrom start of study treatment until first documentation of PD or death due to any cause or censoring date (maximum of 257.3 weeks and 114.6 weeks of treatment exposure for melanoma participants and mCRC participants respectively)PFS was defined as time from date of first study treatment intake to date of first documented PD or death due to any cause. If a participant did not have an event, data censoring was done at the date of last adequate tumor assessment. PD was defined for target disease as at least a 20% increase in sum of longest diameters of all measured target lesions, taking as reference smallest sum on study (this included baseline sum if that was smallest on study), sum also demonstrated absolute increase of \>= 5 mm, or appearance of \>=1 new lesions. For non-target disease: PD was defined as unequivocal progression of pre-existing lesions and if overall tumor burden increased sufficiently to merit discontinuation of therapy; appearance of any new unequivocal malignant lesion was also considered PD. Analysis was performed using Kaplan-Meier method.
Duration of Response (DOR): Dose Escalation PhaseFrom first observation of response until first time of PD or death due to any cause (Maximum of 556.1 weeks of treatment exposure)DOR was defined as the time from first observation of response CR or partial response \[PR\]) to the first time of progression or death. CR was defined as complete disappearance of all target and non-target lesions, and sustained for at least 4 weeks apart before progression. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<) 10 millimeter (mm). PR defined as at least 30 percent (%) decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters. For target disease, PD=at least a 20% increase in sum of longest diameters of all measured target lesions, taking as reference smallest sum on study, sum also demonstrated absolute increase of \>= 5 mm, or appearance of \>=1 new lesions. For non-target disease: PD=unequivocal progression of pre-existing lesions and if overall tumor burden increased sufficiently to merit discontinuation of therapy; appearance of any new unequivocal malignant lesion.
Time to Response (TTR): Dose Escalation PhaseFrom date of start of treatment until CR or PR or censoring date (maximum of 556.1 weeks of treatment exposure)TTR was defined as the time from date of treatment until first documented response (CR or PR). CR was defined as complete disappearance of all target and non-target lesions sustained for at least 4 weeks apart before progression. Any pathological lymph nodes (whether target or non-target) reduced in short axis to \<10 mm. PR was defined as at least 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters. Participants who did not achieve a confirmed PR or CR, were censored at last adequate tumor assessment date when they did not progress (including deaths not due to underlying disease) or at maximum follow-up (from study start to study end date) when participant had an event for progression-free survival. Individual participant data have been reported for this outcome measure.
DOR: Dose Expansion PhaseFrom first observation of response until first time of PD or death due to any cause (maximum of 257.3 weeks and 114.6 weeks of treatment exposure for melanoma participants and mCRC participants respectively)DOR was defined as the time from first observation of response (CR or PR\] to the first time of progression or death. CR was defined as complete disappearance of all target and non-target lesions and sustained for at least 4 weeks apart before progression. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to (\<10 mm.

Individual participant data have been reported for this outcome measure.
Overall Survival (OS): Dose Expansion PhaseFrom start of study treatment until date of death or censoring date (maximum of 257.3 weeks and 114.6 weeks of treatment exposure for melanoma participants and mCRC participants respectively)Overall survival was defined as the time from the date of first study treatment to the date of death due to any cause.

DOR: Dose Expansion Phase

DOR was defined as the time from first observation of response (CR or PR\] to the first time of progression or death. CR was defined as complete disappearance of all target and non-target lesions and sustained for at least 4 weeks apart before progression. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to (\<10 mm. PR defined as at least 30 percent (%) decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters. For target disease, PD=at least a 20% increase in sum of longest diameters of all measured target lesions, taking as reference smallest sum on study, sum also demonstrated absolute increase of \>= 5 mm, or appearance of \>=1 new lesions. For non-target disease: PD=unequivocal progression of pre-existing lesions and if overall tumor burden increased sufficiently to merit discontinuation of therapy; appearance of any new unequivocal malignant lesion.

Time frame: From first observation of response until first time of PD or death due to any cause (maximum of 257.3 weeks and 114.6 weeks of treatment exposure for melanoma participants and mCRC participants respectively)

Number of Participants According to Tumor Response Per RECIST Criteria: Dose Expansion

umor response included: CR, PR, stable disease and disease progression (PD). CR=complete disappearance of all target and non-target lesions sustained for at least 4 weeks apart before progression. Any pathological lymph nodes (whether target or non-target) reduced in short axis to \<10 mm. PR=at least 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease=neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for PD. For target disease, PD=at least a 20% increase in sum of longest diameters of all measured target lesions, taking as reference smallest sum on study, sum also demonstrated absolute increase of \>= 5 mm, or appearance of \>=1 new lesions. For non-target disease: PD=unequivocal progression of pre-existing lesions and if overall tumor burden increased sufficiently to merit discontinuation of therapy; appearance of any new unequivocal malignant lesion.

Time frame: From start of study treatment until first documentation of PD or death due to any cause or censoring date (maximum of 257.3 weeks and 114.6 weeks of treatment exposure for melanoma participants and mCRC participants respectively)

Time to Response (TTR): Dose Escalation Phase

TTR was defined as the time from date of treatment until first documented response (CR or PR). CR was defined as complete disappearance of all target and non-target lesions sustained for at least 4 weeks apart before progression. Any pathological lymph nodes (whether target or non-target) reduced in short axis to \<10 mm. PR was defined as at least 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters. Participants who did not achieve a confirmed PR or CR, were censored at last adequate tumor assessment date when they did not progress (including deaths not due to underlying disease) or at maximum follow-up (from study start to study end date) when participant had an event for progression-free survival. Individual participant data have been reported for this outcome measure.

Time frame: From date of start of treatment until CR or PR or censoring date (maximum of 556.1 weeks of treatment exposure)

Population: FAS included all participants who received at least one dose of encorafenib.'Overall Number of Participants Analyzed' signifies participants evaluable for this outcome measure. Only participants with complete or partial response were included in the analysis.

TTR: Dose Expansion Phase

TTR was defined as the time from date of treatment until first documented response (CR or PR). CR was defined as complete disappearance of all target and non-target lesions sustained for at least 4 weeks apart before progression. Any pathological lymph nodes (whether target or non-target) reduced in short axis to \<10 mm. PR was defined as at least 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters. Participants who did not achieve a confirmed PR or CR, were censored at last adequate tumor assessment date when they did not progress (including deaths not due to underlying disease) or at maximum follow-up (from study start to study end date) when participant had an event for progression-free survival. Individual participant data have been reported for this outcome measure.

Time frame: From date of start of treatment until CR or PR or censoring date (maximum of 257.3 weeks and 114.6 weeks of treatment exposure for melanoma participants and mCRC participants respectively)

Population: FAS included all participants who received at least one dose of encorafenib. 'Overall Number of Participants Analyzed' signifies participants evaluable for this outcome measure. Only participants with complete or partial response were included in the analysis.
