Clinical Trial Summary

This phase II trial studies how well inotuzumab ozogamicin and blinatumomab work in treating patients with CD22-positive B-lineage acute lymphoblastic leukemia that is newly diagnosed, has come back, or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as inotuzumab ozogamicin and blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Description:

PRIMARY OBJECTIVES: I. To confirm tolerability of the combination regimen of inotuzumab ozogamicin followed by blinatumomab. II. To estimate the 1-year event-free survival of older, transplant-ineligible patients with newly diagnosed, Philadelphia (Ph)-negative, CD22-positive, B-cell acute lymphoblastic leukemia (ALL) treated with inotuzumab ozogamicin induction followed by blinatumomab consolidation. (Cohort 1) III. To estimate the 1-year event-free survival of patients with relapsed or refractory Ph-negative, CD22-positive, B-cell ALL treated with inotuzumab ozogamicin induction followed by blinatumomab consolidation. (Cohort 2) SECONDARY OBJECTIVES: I. To estimate the median, 1-year, and 3-year overall survival (OS) in all eligible patients. (Cohort 1) II. To estimate the median, 1-year, and 3-year relapse-free survival (RFS) in all eligible patients. (Cohort 1) III. To estimate the median and 3-year event-free survival (EFS) in all eligible patients. (Cohort 1) IV. To estimate the complete response (CR) rate and overall response rate (ORR, defined as complete response [CR] + complete response with incomplete count recovery [CRi]) to inotuzumab ozogamicin followed by blinatumomab (regimen CR rate and ORR). (Cohort 1) V. To estimate the CR rate and ORR (CR + CRi) to inotuzumab ozogamicin induction alone (induction CR and ORR). (Cohort 1) VI. To estimate the minimal residual disease (MRD) negativity rate in subjects achieving a CR or CRi. (Cohort 1) VII. To estimate the treatment-related mortality with this regimen. (Cohort 1) VIII. To describe the safety and tolerability of this regimen. (Cohort 1) IX. To estimate the median, 1-year, and 3-year OS in all eligible patients. (Cohort 2) X. To estimate the median, 1-year, and 3-year RFS in all eligible patients. (Cohort 2) XI. To estimate the median and 3-year EFS in all eligible patients. (Cohort 2) XII. To estimate ORR (CR/CRi and CR/complete response with partial hematologic recovery [CRh]) to blinatumomab in patients with ALL refractory to inotuzumab ozogamicin. (Cohort 2) XIII. To estimate the CR, CRi, and CRh rates at defined time points and cumulatively for the entire regimen. (Cohort 2) XIV. To determine the MRD negativity (< 10^-4) rate at defined time points including prior to allogeneic HCT and cumulatively in patients achieving a CR, CRh, or CRi. (Cohort 2) XV. To determine the allogeneic hematopoietic cell transplantation (HCT) rate in eligible subjects. (Cohort 2) XVI. To estimate the treatment-related mortality with this regimen. (Cohort 2) XVII. To describe the safety and tolerability of this regimen. (Cohort 2) OTHER OBJECTIVES: I. Results of the primary analysis will be examined for consistency, while accounting for the stratification factors and/or covariates of baseline quality of life (QOL) and fatigue. CORRELATIVE SCIENCE OBJECTIVES: I. To correlate specific karyotype groups (normal or various primary and secondary chromosomal abnormalities) with clinical and laboratory parameters. II. To correlate specific karyotype groups with response rates, response duration, survival, and cure in patients treated with inotuzumab ozogamicin followed by blinatumomab. III. To correlate specific karyotype groups with MRD. IV. To determine karyotype changes at relapse and the influence of the type of change (or no change) in karyotype at relapse. V. To assess the correlation of quantitative MRD post-induction with inotuzumab ozogamicin and at sequential consolidation time points with blinatumomab with RFS, EFS, and OS. VI. To correlate the influence of MRD status (detectable versus [vs.] not and as a continuous measure) in relation to EFS, RFS, and OS with other clinical and biological factors (e.g. previously untreated vs. relapsed disease cohorts; age, initial white blood cell [WBC] count, cytogenetics). VII. To identify genetic variants and predictors of ex vivo resistance. VIII. To identify genetic variants and predictors of MRD. IX. To identify genetic variants and predictors of relapse. X. To determine inter-patient variability in drug sensitivity of adult ALL. XI. To examine the associations of drug sensitivity with host and leukemia molecular features. EXPLORATORY OBJECTIVES: I.

To compare the median, 1-year, and 3-year RFS, EFS, and OS among patients achieving MRD-negative vs. MRD-positive CR/CRi at any time. (Cohort 1) IV. To describe the rate, severity, and timing of sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) of the liver after limited inotuzumab ozogamicin exposure and identify risk factors for SOS/VOD. (Cohort 1) V. To estimate the rate of cytokine release syndrome in this population. (Cohort 1) VI. To estimate the median, 1-year, and 3-year RFS from time of CR/CRi to inotuzumab ozogamicin in patients receiving inotuzumab ozogamicin followed by blinatumomab and not undergoing allogeneic hematopoietic cell transplantation (HCT). (Cohort 2) VII. To estimate median, 1-year, and 3-year OS after CR/CRi to inotuzumab ozogamicin in patients not undergoing allogeneic HCT. (Cohort 2) VIII. To compare in a non-randomized fashion median, 1-year, and 3-year OS, median, 1-year, and 3-year RFS, cumulative incidence of relapse (CIR), and non-relapse mortality (NRM) between patients achieving CR/CRi and receiving consolidation with or without allogeneic HCT. (Cohort 2) IX.

Patients with CR/CRi at the end of Course II continue to Course IIIB. COURSE IB/IC: Patients receive inotuzumab ozogamicin IV over 1 hour on days 1, 8, and 15. Treatment continues for 1 course (28 days) in the absence of disease progression or unacceptable toxicity. COURSE II: Patients receive blinatumomab IV continuously on days 1-28 and 43-70. Treatment continues for 1 course (84 days) in the absence of disease progression or unacceptable toxicity. COURSE IIIA: Patients receive blinatumomab IV continuously on days 1-28 and 43-70. Treatment continues for 1 course (84 days) in the absence of disease progression or unacceptable toxicity. COURSE IIIB: Patients receive blinatumomab IV continuously on days 1-28, 43-70, and 85-112.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Rate of cytokine release syndrome (Cohort 1)	Point and interval estimates of the rate will be shown using a 95% binomial confidence interval.	Up to 10 years
Other	Sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) of the liver	The rate of, timing of, and risk factors for SOS/VOD of the liver after limited inotuzumab ozogamicin exposure. Point and interval estimates of the rate will be shown using a 95% binomial confidence interval. A summary of the timing and risk factors for SOS/VOD of the liver will be provided.	Up to 10 years
Other	OS	Will compare between patients achieving CR/CRi and receiving consolidation with allogeneic hematopoietic cell transplantation versus (vs.) patients achieving CR/CRi and receiving consolidation without allogeneic hematopoietic cell transplantation. The median, 1-year, and 2-year OS will be compared between the above two groups. The distribution of OS for each group will be estimated using the Kaplan-Meier method.	Up to 2 years
Other	RFS	Will compare between patients achieving CR/CRi and receiving consolidation with allogeneic hematopoietic cell transplantation vs. patients achieving CR/CRi and receiving consolidation without allogeneic hematopoietic cell transplantation. The median, 1-year, and 2-year RFS will be compared between the above two groups. The distribution of RFS for each treatment arm will be estimated using the Kaplan-Meier method.	Up to 2 years
Other	Cumulative incidence of relapse (CIR)	Will compare between patients achieving CR/CRi and receiving consolidation with allogeneic hematopoietic cell transplantation vs. patients achieving CR/CRi and receiving consolidation without allogeneic hematopoietic cell transplantation. Competing risk analysis will be done to compare the relapse rates between the above two groups. In this analysis, death will be considered a competing event. Relapse rates at the 1-year and 2-year time points will be estimated. Other time points of interest may be estimated as well.	Up to 2 years
Other	Non-relapse mortality	Will compare between patients achieving CR/CRi and receiving consolidation with allogeneic hematopoietic cell transplantation vs. patients achieving CR/CRi and receiving consolidation without allogeneic hematopoietic cell transplantation. Competing risk analysis will be done to compare the mortality rates between the above two groups. In this analysis, relapse will be considered a competing event. Mortality rates at the 1-year and 2-year time points will be estimated. Other time points may be estimated as well.	Up to 2 years
Primary	Event-free survival	Will be defined as time from start of treatment to failure to achieve complete response (CR)/complete response with incomplete count recovery (CRi) after completing Course II of blinatumomab, relapse after CR/CRi, progression on study requiring withdrawal from study therapy, or death from any cause	At 1 year
Secondary	Overall survival (OS)	Will be evaluated using the Kaplan-Meier method. A 95% confidence interval for the 1- and 3-year rates will be constructed using a point-wise confidence interval for the survival function based on a log-minus-log transformation. Will also calculate a 95% confidence interval by using a point-wise confidence interval for the survival function based on a log-minus-log transformation.	Time from start of study therapy to death from any cause censored at the last known alive date, assessed up to 10 years
Secondary	Relapse-free survival (RFS)	Will be evaluated using the Kaplan-Meier method. A 95% confidence interval for the 1- and 3-year rates will be constructed using a point-wise confidence interval for the survival function based on a log-minus-log transformation. Will also calculate a 95% confidence interval by using a point-wise confidence interval for the survival function based on a log-minus-log transformation.	Time from first CR/CRi to progressive disease (relapse, treatment discontinuation due to health deterioration) or death, assessed up to 10 years
Secondary	Event-free survival (EFS)	Will be evaluated using the Kaplan-Meier method. A 95% confidence interval for the 1- and 3-year rates will be constructed using a point-wise confidence interval for the survival function based on a log-minus-log transformation. Will also calculate a 95% confidence interval by using a point-wise confidence interval for the survival function based on a log-minus-log transformation.	Time from start of treatment to failure to achieve CR/CRi after completing Course II of blinatumomab, relapse after CR/CRi, progression on study requiring withdrawal from study therapy, or death from any cause, assessed up to 10 years
Secondary	Complete and overall response rate	Point and interval estimates of the rates will be shown using a 95% binomial confidence interval.	Up to 10 years
Secondary	Minimal residual disease negativity		Up to 10 years
Secondary	Allogeneic hematopoietic cell transplantation rate (Cohort 2)	Point and interval estimates of the rate will be shown using a 95% binomial confidence interval.	Up to 10 years
