Supplementary Methods Statistical Analyses
Progression-free survival sensitivity analyses: Several sensitivity analyses were performed for the primary endpoint, progression-free survival (PFS). A stratified log-rank test, the derivation of the median with 95% CI, and calculation of hazard ratio from a Cox proportional hazards model, which included treatment arm and stratification factors, were repeated for each of the analyses as described.
Assess impact of missing response assessments (actual event) o Regardless of the number of preceding missing assessments, the actual event date of
progression, relapse, or death was used as the PFS event date Assess impact of missing response assessments (backdating event)
o In case of a documented PFS event after 1 or more subsequent missing response assessments, PFS was considered to have occurred at the next scheduled response assessment after the date of the last adequate response assessment
Assess impact of patients who are no longer followed for disease assessments (dropout); the following were considered PFS events:
o All patients who were censored in the primary analysis due to lack of or inadequately documented disease progression, relapse, or death while having progressive disease as the reason for end of treatment or study evaluation completion
o All patients who stopped disease follow-up due to new anticancer therapy; this applied for the following situations:
New anticancer therapy started (documented as on antineoplastic therapy after treatment discontinuation, per the case report form field); the start date of new anticancer therapy was considered the PFS event date
Reason for end of treatment or study evaluation completion is the start of a new antineoplastic therapy; the date of documentation was considered the PFS event date
o All patients whose PFS censoring reason was PFS event after ≥2 missing adequate assessments; the date of the disease progression, relapse, or death assessment was used as the PFS event date. In cases where more than 1 criterion applied, the earliest date was used as the PFS event date
Assess impact of using independent review committee (IRC) assessment o Used the IRC assessment instead of investigator’s evaluation for all patients. Used the IRC
assessment for patients with at least 1 M-protein assessment not performed by electrophoresis and used the investigator’s evaluation for patients with M-protein measurements
Investigator assessment as per-protocol set analysis o Included only the per-protocol set in the analysis
IRC assessment as per-protocol set analysis o Included only the per-protocol set in the analysis
Assess impact of prognostic factors o Used multivariate Cox regression model
Supportive analyses for PFS: A multivariate Cox model analysis was performed if the primary analysis of
PFS was statistically significant. The following prognostic factors in the Cox proportional hazards model were included:
Sex Age: <65 years, ≥65 years Race: Caucasian, Asian, other Renal impairment: yes, no Prior stem cell transplantation: yes, no Clinical staging of multiple myeloma according to ISS: stage I, stage II and III Geographic region: Europe, South East Asia, Western Pacific, Africa, Americas, Eastern
Mediterranean Prior use of bortezomib: yes, no Number of prior line of therapy: 1, 2/3
2
Prior use of immunomodulatory agents (IMiDs; defined as thalidomide or lenalidomide): yes, no Prior use of IMiDs and bortezomib: yes, no Multiple myeloma characteristics: relapsed, relapsed-and-refractory
Several subgroup analyses were conducted for the same variables mentioned above in addition to the
cytogenetic risk group. Hazard ratios and 2-sided 95% CIs were provided based on the Cox proportional hazards model. To derive estimates by subgroup, this model included treatment and stratification factors.
Key secondary endpoint: Overall survival (OS), the key secondary endpoint, was tested only if the primary endpoint was statistically significant. In order to calculate the final OS analysis, the median OS of and PAN-BTZ- Dex was 20 months and Pbo-BTZ-Dex was 14·6 months and 20 months, respectively (HR = 0·73).Irrespective of whether OS was tested, alpha for OS was spent according to the OS group sequential plan at each PFS analysis. The final analysis of OS is planned when 415 survival events have occurred.
Other secondary endpoints: Other secondary endpoints of objective response rate (ORR), near complete or complete response (nCR/CR) rate, time to response, and response duration were calculated based on modified European Group for Blood and Marrow Transplantation criteria using the full analysis set. Point estimate and exact 95% 2-sided CI of ORR and nCR/CR rate were calculated and analyzed using unadjusted Cochran-Mantel-Haenszel test based on strata at randomization. The statistical test of nCR/CR rate was performed using post hoc analysis. Median time to response, time to progression, and response duration were estimated using the Kaplan-Meier method.

Appendix Table 4. Criteria for dosing delays, dose-reductions, and re-initiation of PAN/placebo due to study drug-related QTcF abnormalities (cycle 1, cycles 2-8)
ECGs to be performed at specified time point
Abnormality Noted Dose Modification Guideline - At any time during a cycle of therapy (including intended day of dosing)
Dose modifications are based on local readings of the average QTcF of triplicate ECGs.
Cycle 1 dose modification criteria:
Pre-dose on cycle 1, days 1 and 5:
3 ECGs separated by 5- 10 minutes, obtained prior to PAN/placebo dosing
Day 1: Average QTcF > 450 msec
Day 5: Average QTcF: ≥ 480 msec to < 500 msec OR > 60 msec increase from baseline average
Check and correct the patient’s serum potassium, magnesium, calcium and phosphorus immediately, as well as evaluate con-meds.
Notify Sponsor and transmit to eRT immediately for prompt review.
If abnormality noted on Day 1 of Cycle 1: Repeat 3 pre-dose ECGs. If the 3 pre-dose ECGs: Do not meet criteria again, discontinue patient from study. Do meet criteria for dosing; administer study drug treatment.
If abnormality noted on Day 5 of Cycle 1: Delay dose at least 3 days and repeat 3 pre-dose ECGs. If the repeat 3 pre-dose ECGs: Do not meet pre-dose ECG criteria again, discontinue patient from study. Do meet pre-dose ECG criteria for dosing and QT prolongation determined to be related to study drug, resume study drug treatment with a dose reduction of 5 mg. If however, it was determined that the QT prolongation was secondary to electrolyte abnormalities or con-meds, continue at the same dose level. Repeat ECGs - pre-dose (× 3), 3-hours post-dose (× 3), on the next scheduled dosing day.
ECGs to be performed at specified time point
Abnormality Noted Dose Modification Guideline - At any time during a cycle of therapy (including intended day of dosing)

Notify Sponsor and transmit to eRT immediately for prompt review.
Next scheduled dosing day: repeat 3 pre-dose ECGs. If these 3 pre- dose ECGs: Do not meet pre-dose ECG criteria for dosing (average QTcF ≤ 480 msec), discontinue patient from study.
Do meet pre-dose ECG criteria for dosing (average QTcF ≤ 480 msec) and QT prolongation determined to be related to study drug, resume study drug treatment with a dose reduction of 5 mg. If however, it was determined that the QT prolongation was secondary to electrolyte abnormalities or con-meds, continue at the same dose level. Repeat ECGs - pre-dose (× 3), 3- hours post-dose (× 3) on the next scheduled dosing day.
Average QTcF ≥ 500 msec Check and correct the patient’s serum potassium, magnesium, calcium and phosphorus immediately.
Notify Sponsor and transmit to eRT immediately for prompt review.
Discontinue patient from study therapy If however, it was determined that the QT prolongation was secondary to electrolyte abnormalities or con- meds: omit dose. On the next scheduled dosing day continue at the same dose level. Repeat ECGs - pre- dose (×3), 3-hours post-dose (× 3), on the next scheduled dosing day.

Appendix Table 5. Drug related adverse events dose modification guidelines for bortezomib
CTCAE Category Dose Modification Guideline - At any time during a cycle of therapy (including intended day of dosing)
Uncomplicated Grade 3 Neutropenia (ANC < 1.0 × 109/L) or uncomplicated Grade 3 Thrombocytopenia (PLT < 50 × 109/L)
No change in dosing
≥ Febrile neutropenia (Grade 3 ANC < 1.0 × 109/L , associated with fever, i.e. temperature ≥ 38.5º C)
or Neutropenia Grade 4 (ANC < 0.5 × 109/L) and/or
Thrombocytopenia Gr 3 (PLT < 50 × 109/L) with bleeding, or Gr 4 (PLT < 25 × 109/L)
Hold therapy until neutropenia and/or thrombocytopenia both resolve to ≤ Grade 2 ;
if only one dose was omitted prior to correction to these levels, BTZ should be restarted at same dose,
if two or more doses were omitted - consecutively, or within the same cycle - then BTZ should be restarted at a reduced dose by one dose level.
Herpes Zoster reactivation any grade Hold therapy until lesions are dry.
Other BTZ related non- hematologic toxicity ≥ Grade 3
Determine attribution of toxicity and hold therapy. If toxicity resolves to ≤ Grade 2, resume therapy with one level dose reduction.

*Analysis included the event whenever it occurred, even after ≥2 missing adequate assessments. †Analysis used the date of the next scheduled assessment for events occurring after ≥1 missing adequate assessments. ‡ Analysis included subsequent antineoplastic therapy, reason for end of treatment as disease progression without investigator documentation, and disease progression after ≥2 missing adequate assessments as events. §IRC assessment was used for all patients. ¶IRC assessment was used for patients without M-protein measurements by electrophoresis. For all other patients, investigator assessment was used. ||Baseline covariates included in the Cox proportional hazard model are treatment group; age group; renal impairment; prior stem cell transplantation; clinical staging according to ISS, sex, race, and geographic region; prior use of IMiDs; prior use of bortezomib and IMiDs; prior use of bortezomib (yes vs no); and number of prior lines of therapy (1 vs 2/3) Hazard ratio and 95% CI of PAN-BTZ-Dex versus Pbo-BTZ-Dex are obtained from stratified Cox model. The 2-sided p value is obtained from the stratified log- rank test. p values for other than the primary analysis are presented for descriptive purposes and for an assessment of the consistency and robustness of the primary analysis in terms of statistical significance.
