Summary

This trial is testing whether adding the drug inotuzumab ozogamicin to the usual treatment can help patients with a specific type of leukemia (Ph+ ALL) achieve remission faster. The study focuses on patients who are beginning their treatment. Inotuzumab ozogamicin is a medication approved for certain types of leukemia.

Who is the study for?
This trial is for adults with newly diagnosed Philadelphia chromosome-positive (Ph+) B-cell Acute Lymphoblastic Leukemia. Participants must have CD22 expression on their cancer cells, be in good physical condition as measured by ECOG status, and have proper organ function. Pregnant or breastfeeding individuals are excluded, as well as those with severe medical conditions, certain heart issues, liver disease, active infections or other cancers.
What is being tested?
The study tests whether adding Inotuzumab Ozogamicin (InO) to standard induction therapy leads to quicker complete molecular remission in Ph+ ALL patients who haven't been treated before. It aims to improve the effectiveness of initial treatment by using this additional anti-cancer drug.
What are the potential side effects?
Potential side effects include reactions related to the immune system's response to InO such as fever and chills during infusion; blood-related issues like low platelet count; liver problems; and an increased risk of infection due to weakened immunity.

Trial Design

3Treatment groups
Experimental Treatment
Group I: Treatment Arm - Interim/Maintenance Phase - Participants in CMRExperimental Treatment7 Interventions
This study arm is for participants who no longer show any detectable signs of BCR-ABL1 (a cancer-causing gene) in response to the previous phase of induction/consolidation treatment (also known as being in "complete molecular remission" or CMR). Participants in this arm will receive 3 courses of interim/maintenance treatment using dasatinib combined with other anti-cancer drugs. Inotuzumab ozogamicin will be added during the fourth course of treatment. These treatments will be given in 28-day and 84-day cycles. If the participant achieves complete molecular remission (no signs of BCR-ABL gene) after 60 days (or more) of treatment, then the treating physician may take the participant off the study for allogenic stem cell transplantation surgery. If the participant does not undergo allogeneic stem cell transplantation after achieving complete molecular remission, they will complete 3 additional courses of maintenance treatment.
Group II: Treatment Arm - Interim/Maintenance Phase - Participants Not in CMRExperimental Treatment7 Interventions
This study arm is for participants whose cancer responded to induction/consolidation treatment, but still shows detectable signs of BCR-ABL1 (a cancer-causing gene), so they are not in complete molecular remission. Participants in this arm will receive 3 courses of treatment using ponatinib combined with other anti-cancer drugs. Inotuzumab ozogamicin will be added during the 4th treatment course. These treatments will be given in 28-day and 84-day cycles. If the participant achieves complete molecular remission (no signs of BCR-ABL gene) after 60 days (or more) of treatment, the treating physician may take the participant off the study for allogenic stem cell transplantation surgery. If the participant does not undergo allogeneic stem cell transplantation after achieving complete molecular remission (CMR), they will complete 3 additional courses of maintenance treatment. If the participant doesn't achieve CMR after 4th treatment course, they will be removed from the study.
Group III: Treatment Arm - Induction/Consolidation Phase - All ParticipantsExperimental Treatment4 Interventions
All participants in this arm will receive the same first round of treatment as part of induction/consolidation therapy. This treatment will use inotuzumab ozogamicin combined with anti-cancer drugs. The additional treatment that participants receive after this first round of treatment will vary based on the participant's response to induction therapy. This phase of treatment will last for 60 days. All participants in this arm will receive the following treatment: Treatment Course I (Induction Phase, 28 days): * Dasatinib 140mg daily continuous * Dexamethasone 10mg/m\^2 PO or IV Days 1-7 and Day 15-Day 22 * InO 0.8mg/m2 Day 8; 0.5mg/m2 D15, 0.5mg/m2 Day 22 * Intrathecal methotrexate 15mg Day 1, Day 28 Treatment Course II (Consolidation Phase, 28 days): * Dasatinib 140mg daily continuous * InO: If in CR/CRi 0.5mg/m2 Day 1, Day 8, Day 15; If not in CR/CRi 0.8mg/m2 on Day 1, 0.5mg/m2 Day 8 and Day 15 * Intrathecal methotrexate 15mg Day 1, Day 28

Prior Approvals
Other Research
Common treatments for Acute Lymphoblastic Leukemia (ALL) include antibody-drug conjugates like inotuzumab ozogamicin, which targets CD22-positive B-cells and delivers a cytotoxic agent to kill cancer cells. Tyrosine kinase inhibitors (TKIs) such as imatinib and dasatinib target the BCR-ABL fusion protein in Philadelphia chromosome-positive ALL, blocking signals that promote cancer cell growth. Traditional chemotherapeutic agents like vincristine, methotrexate, and cytarabine disrupt cell division and DNA replication. These treatments are essential for ALL patients as they aim to eradicate leukemic cells, achieve remission, and reduce the risk of relapse.
