NCT Number: NCT04632992
This is a Phase II, multicenter, non-randomized, open-label, multi-arm study designed to evaluate the safety and efficacy of targeted therapies as single agents or in rational, specified combinations in participants with advanced unresectable or metastatic solid tumors determined to harbor specific biomarkers.
Patients will be enrolled based on local testing performed at a Clinical Laboratory Improvement Amendments (CLIA)-certified or equivalently accredited diagnostic laboratory. The multi-arm structure of the MyTACTIC study allows patients with solid tumors to be treated with a drug or drug regimen tailored to their biomarker identified at screening.

Time frame: Up to 32 months
Confirmed objective response rate (cORR)=percentage of participants with best response as complete response (CR) or partial response (PR) for measurable disease & CR for non-measurable disease. Confirmation=CR/PR on 2 consecutive visits ≥4 weeks apart for 3-week cycles & ≥6 weeks apart for 4-week cycles. Per RECIST, CR=disappearance of all target lesions. PR= ≥30% decrease in sum of diameters of target lesions, in absence of CR. Per RANO, CR=complete disappearance of all measurable & non-measurable disease for ≥4 weeks; no new lesions/abnormality on T2/FLAIR imaging; stable/improved non-enhancing lesions; participants must be off corticosteroids or on physiological doses; clinical status stable/improved. PR= ≥50% decrease in the sum of products of perpendicular diameters of measurable enhancing lesions on T2/FLAIR imaging for ≥4 weeks; no progression of non-measurable T1 disease; stable/improved non-enhancing lesions; corticosteroid dose ≤ baseline; clinical status stable/improved.
Time frame: Time from start of treatment to the first occurrence of disease progression or death from any cause (Up to 32 months)
PFS=time from start of treatment to the first occurrence of disease progression (PD) or death from any cause, whichever occurs first, per RECIST v1.1, or RANO. Per RECIST, PD=≥20% increase in sum of diameters of lesions, using the smallest sum during the study as reference, including baseline (BL). Per RANO, PD= ≥25% increase in sum of products of perpendicular diameters of enhancing lesions compared to smallest tumor measurement at BL/best response, on stable/increasing corticosteroids (CS) dose; Significant/ ≥25% increase of T2/FLAIR non-enhancing lesion on stable/increasing CS dose compared to BL/best response after therapy start; Presence of new lesions/increase of enhancement; Clear progression of non-measurable disease; Definite clinical deterioration only due to tumor/decrease in CS dose; Failure to return for evaluation due to death/deterioration. Kaplan-Meier methodology was used to estimate PFS; patients without an event were censored on the last available assessment day.
Time frame: Time from the date of the first confirmed CR/PR to PD or death from any cause (Up to 32 months)
DOR was defined as the time from the date of the first confirmed complete response (CR) or partial response (PR) to disease progression (PD) or death from any cause, whichever occurs first, as determined by the investigator according to RECIST v1.1 or RANO. CR & PR were defined per RECIST or RANO as outlined in the description for the cORR outcome measure (OM). PD was defined per RECIST or RANO as outlined in the description for the PFS OM. Kaplan-Meier methodology was used to estimate the median DOR. The 95% confidence intervals for the median DOR were computed by the method of Brookmeyer and Crowley. Participants who did not experience death or PD were censored on the day of the last available assessment.
Time frame: At Months 3, 6, 9 and 12
The PFS rates were calculated using the Kaplan-Meier (KM) method to estimate the percent survival probability of participants (i.e., PFS event-free: did not experience PD or death from any cause) in each treatment arm at landmark timepoints. The 95% confidence intervals for each PFS rate were computed by the method of Greenwood. PFS was defined as the time from the start of study treatment to the first occurrence of PD or death from any cause, whichever occurs first, as determined by the investigator according to RECIST v1.1 or RANO. PD was defined per RECIST or RANO as outlined in the description for the PFS OM. Participants who did not experience death or PD were censored on the day of the last available assessment. The number analyzed per landmark timepoint actually represents the number of participants who remained at risk of experiencing a PFS event at that timepoint. Percentages are rounded off to the nearest decimal point.
Time frame: Up to 32 months
Disease control rate was defined as the percentage of participants whose best response was confirmed CR, confirmed PR, or a response of CR, PR, stable disease (SD), or non-CR/non-PD for a minimum of 98 days for 28-day cycle arms or 70 days for 21-day cycle arms after the first treatment date. CR & PR were defined per RECIST/RANO as outlined in the description for the cORR OM. SD per RECIST: Neither sufficient shrinkage to qualify for CR or PR nor sufficient increase to qualify for PD. SD per RANO: Participant does not qualify for CR, PR, or minor response or PD; Stable non-enhancing (T2/FLAIR) lesions or abnormalities on same or lower dose of corticosteroids compared to baseline; No new lesions or new T2 or FLAIR abnormalities apart from those consistent with radiation effect, & no new or increased enhancement; Participants on a should be corticosteroid dose that is not greater than dose at baseline scan & is stable or improved clinically; Clinical status, stable/improved.
Time frame: From initiation of study drug until 28 days after the final dose of study drugs other than atezolizumab and until 90 days after the final dose of atezolizumab (Up to 32 months)
An AE is an untoward medical occurrence in participant administered a pharmaceutical product & regardless of causal relationship with the product. An AE can therefore be any unfavorable & unintended sign (including an abnormal laboratory finding), symptom/disease temporally associated with use of investigational product, whether or not considered related to it. AEs were graded for severity according to NCI CTCAE v5.0. Grade 1= Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; or intervention not indicated; Grade 2=Moderate; minimal, local or non-invasive intervention indicated; or limiting age-appropriate instrumental activities of daily living; Grade 3 = Severe or medically significant, but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; or limiting self-care activities of daily living; Grade 4= Life-threatening consequences/urgent intervention indicated; Grade 5= Death related to adverse event.
