Trial Summary

What is the purpose of this trial?

This phase II clinical trial tests a chemotherapy regimen (dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin with or without rituximab \[DA-EPOCH+/-R\]) with the addition of targeted therapy (tafasitamab) for the treatment of patients with newly diagnosed Philadelphia chromosome negative (Ph-) B acute lymphoblastic leukemia (B-ALL). Chemotherapy drugs, such as those in EPOCH+/-R, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Tafasitamab is in a class of medications called monoclonal antibodies. It works by helping the body to slow or stop the growth of cancer cells. Adding tafasitamab to the DA-EPOCH+/-R regimen may work better than DA-EPOCH+/-R alone in treating newly diagnosed Ph- B-ALL.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, it mentions that no prior systemic therapy for ALL is allowed except to control acute symptoms, so it's best to discuss your current medications with the trial team.

What data supports the effectiveness of the drugs used in the Chemotherapy + Targeted Therapy for Acute Lymphoblastic Leukemia trial?

Research shows that a combination of drugs including prednisone, vincristine, and etoposide (VP-16) can lead to complete remission in some children with relapsed acute lymphoblastic leukemia (ALL). Additionally, a study found that a regimen including vincristine, doxorubicin, and prednisone achieved a high complete remission rate in adults with ALL.12345

Is the combination of chemotherapy and targeted therapy for acute lymphoblastic leukemia generally safe in humans?

The research indicates that certain chemotherapy drugs like idarubicin and liposomal daunorubicin, when used in combination with other treatments, have shown low non-hematologic toxicity (side effects not related to blood) in patients with acute lymphoblastic leukemia. This suggests that these treatments can be generally safe for humans, although individual responses may vary.678910

What makes the chemotherapy and targeted therapy treatment for acute lymphoblastic leukemia unique?

This treatment combines multiple drugs, including cyclophosphamide, doxorubicin, etoposide, prednisone, and vincristine, which are used together to target leukemia cells in different ways. The combination aims to improve outcomes by using drugs with different mechanisms of action, potentially overcoming resistance seen with other treatments.1231112

Treatment Details

Interventions

  • Cyclophosphamide (Alkylating agents)
  • Doxorubicin (Anti-tumor antibiotic)
  • Etoposide (Topoisomerase I inhibitors)
  • Prednisone (Corticosteroid)
  • Tafasitamab (Monoclonal Antibodies)

Findings from Research

In a study of 50 children with acute lymphoblastic leukemia (ALL) who were in their first to fifth relapse, a three-drug reinduction regimen including etoposide (VP-16) led to a complete remission in 34% of patients who received at least two courses of treatment.
The results suggest that prior resistance to teniposide (VM-26) does not prevent patients from responding to VP-16, indicating that higher doses and more frequent administration of VP-16 may effectively overcome resistance, although further research is needed for long-term treatment strategies.
Etoposide (VP-16) with prednisone and vincristine for the treatment of refractory acute lymphoblastic leukemia.Abromowitch, M., Bowman, WP., Ochs, J., et al.[2017]
In a phase II study involving 20 heavily pretreated children with relapsed acute lymphoblastic leukemia (ALL), the combination of ifosfamide and etoposide (VP16) resulted in a 40% complete remission rate, demonstrating significant efficacy in this challenging patient population.
The treatment was generally well tolerated, with myelosuppression being the most common side effect, indicating that while the therapy is effective, careful monitoring for toxicity is necessary.

In a study of 31 pediatric patients with relapsed acute lymphoblastic leukemia (ALL), topotecan administered before standard induction therapy resulted in an impressive 89.3% response rate, significantly reducing circulating blast cells.
The combination of topotecan with standard induction therapy led to a 74.2% complete response rate, indicating that this regimen is effective and well-tolerated, despite some hematologic and gastrointestinal toxicities.

In a study of 365 adults with acute lymphoblastic leukemia (ALL), those treated with the HCVAD chemotherapy regimen had a higher complete remission rate (91%) and better three-year event-free survival (40%) compared to those treated with the VAD regimen (73% and 23%, respectively).
The persistence of peripheral blood blasts on day 7 (D7PBb) and bone marrow blasts on day 14 (D14BMb) after starting chemotherapy had different prognostic implications depending on the treatment regimen, highlighting the importance of early clearance of leukemia cells for better outcomes.
Persistence of peripheral blood and bone marrow blasts during remission induction in adult acute lymphoblastic leukemia confers a poor prognosis depending on treatment intensity.Cortes, J., Fayad, L., O'Brien, S., et al.[2015]
In a clinical phase II study involving 70 patients with refractory or early relapse acute lymphoblastic leukemia (ALL) and T-cell non-Hodgkin's lymphoma (NHL), the combination of high-dose idarubicin and high-dose cytosine-arabinoside (ARA-C) resulted in a complete remission rate of 78%.
The treatment was well-tolerated, with limited non-hematologic side effects primarily related to infections, suggesting that this regimen could be a feasible option for patients with difficult-to-treat leukemia without compromising future bone marrow transplantation.

In a clinical phase II study involving 70 patients with refractory or early relapse acute lymphoblastic leukemia (ALL) and T-cell lymphoblastic non-Hodgkin's lymphoma (NHL), 78% achieved complete remission with the combination of high-dose idarubicin and high-dose cytosine-arabinoside, indicating strong antileukemic activity.
The treatment was well-tolerated, with limited non-hematologic side effects primarily related to infections, suggesting that this regimen could be a feasible option for patients while still allowing for potential bone marrow transplantation afterward.

In a study of 110 patients with metastatic Ewing sarcoma or primitive neuroectodermal tumor (PNET), the combination of topotecan and cyclophosphamide showed promising activity, with 21 out of 37 patients achieving partial responses.
Amifostine, intended as a cytoprotective agent, did not provide myeloprotection, and overall survival rates remained unchanged compared to previous studies, indicating that while some treatments showed activity, the prognosis for these patients remains poor.

In a study of 42 adult patients with poor-risk acute leukemia, the combination of liposomal daunorubicin (DNX) and high-dose arabinosyl cytosine (HDAC) resulted in a high complete remission rate of 51% in acute non-lymphocytic leukemia (ANLL) and 91% in acute lymphocytic leukemia (ALL).
The treatment was associated with low non-hematologic toxicity, making it a safer option for elderly and heavily pretreated patients, with negligible side effects such as no intestinal toxicity and only one case of bacteremia.

In a study testing 11 anti-cancer agents on 4 pediatric ALCL cell lines, vinblastine was found to be the most effective, significantly inhibiting cell growth in a time- and dose-dependent manner, with effective doses as low as 0.0002 microM/L after 24 hours.
Vinblastine treatment not only inhibited cell growth but also induced apoptosis and disrupted mitotic spindle formation, supporting its use as a first-line treatment in high-risk pediatric ALCL patients.
