What You Need to Know Before You Apply

What is the purpose of this trial?

This study is evaluating whether a combination of drugs may help treat acute promyelocytic leukemia.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is the combination of Tretinoin and Arsenic Trioxide safe for treating leukemia?

The combination of Tretinoin (all-trans retinoic acid) and Arsenic Trioxide has been used to treat acute promyelocytic leukemia and is generally well tolerated. Common side effects include fatigue, rash, fluid retention, and changes in heart rhythm, but serious side effects are rare. Studies have shown that this treatment can be safe when used at recommended doses. ^{1 2 3 4 5}

What makes the drug combination of Tretinoin and Arsenic Trioxide unique for treating leukemia?

This drug combination is unique because Arsenic Trioxide is highly effective in treating acute promyelocytic leukemia (APL), especially in relapsed cases, and when combined with Tretinoin, it can improve event-free and overall survival rates. Additionally, this combination can achieve complete molecular remission even in patients with resistant forms of the disease, offering a novel approach compared to traditional chemotherapy. ^{2 6 7 8 9}

What data supports the effectiveness of the drug arsenic trioxide in treating leukemia?

Arsenic trioxide has shown to be highly effective in treating acute promyelocytic leukemia (APL), achieving complete remission in over 80% of patients with relapsed disease and improving event-free survival when used as part of consolidation therapy. It has also been studied in other types of leukemia, showing some effectiveness when combined with other drugs. ^{2 7 8 9 10}

What Are the Treatments Tested in This Trial?

Interventions

• Arsenic Trioxide
• Gemtuzumab Ozogamicin
• Tretinoin

Trial Overview The trial is testing how well tretinoin and arsenic trioxide work together, with or without an additional drug called gemtuzumab ozogamicin, in treating newly diagnosed APL patients. The goal is to see if adding gemtuzumab ozogamicin can kill more cancer cells without harming normal cells.

INDUCTION: Patients receive tretinoin PO BID, arsenic trioxide IV over 1-2 hours daily, and gemtuzumab ozogamicin IV over 2 hours once at weeks 1-4. CONSOLIDATION: Patients achieving CR receive arsenic trioxide IV 5 days per week during weeks 1-4, 9-12, 17-20, and 25-28 and tretinoin PO BID for 2 weeks on and 2 weeks off. Treatment repeats every 8 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Published Research Related to This Trial

Arsenic trioxide is highly effective in treating acute promyelocytic leukemia (APL), achieving complete remissions in over 80% of relapsed patients and molecular remission in 90% of those who reach complete remission.

Clinical trials indicate that arsenic trioxide not only benefits relapsed APL patients but also shows promise in first-line treatment and consolidation therapy, improving event-free and overall survival rates.

New data with arsenic trioxide in leukemias and myelodysplastic syndromes. Sekeres, MA.[2019]

Arsenic trioxide (As2O3) combined with all-trans retinoic acid (ATRA) successfully achieved complete molecular remission in a patient with secondary, relapsed, resistant promyelocytic leukemia, despite the patient's severe complications.

The treatment was notable for its lack of significant toxicity, allowing the patient to undergo a bone marrow autograft after reaching complete remission.

Arsenic trioxide, combined with low-dose ara-C, was tested in a phase I/II trial involving 113 patients (49 with myelodysplastic syndrome and 64 with acute myeloid leukemia), showing that the treatment was generally well tolerated and led to complete remissions in both groups.

This combination therapy demonstrated efficacy even in patients with poor baseline health and unfavorable genetic profiles, highlighting arsenic trioxide's potential as a valuable treatment option for high-risk blood cancers.

In a study of 481 patients with untreated acute promyelocytic leukemia (APL), the addition of arsenic trioxide (As(2)O(3)) to standard treatment significantly improved event-free survival at 3 years (80% vs. 63%).

Patients receiving As(2)O(3) also showed better disease-free survival rates (90% vs. 70% at 3 years), indicating that As(2)O(3) is an effective consolidation treatment for newly diagnosed APL.

In a study of 129 adult patients with acute promyelocytic leukemia (APL), maintenance therapy using ATRA, arsenic trioxide, and ascorbic acid (AAA) demonstrated a favorable safety profile with no severe organ toxicities and resulted in high long-term survival rates, with 5-year overall survival at 94%.

The maintenance therapy led to a low relapse rate of 13% over a median follow-up of 100 months, indicating that AAA is effective in maintaining first complete remission (CR1) in APL patients.

In a study of 20 patients with acute promyelocytic leukemia (APL), the combination of all-trans retinoic acid (ATRA) and arsenic trioxide (As(2)O(3)) resulted in a high complete remission (CR) rate of 94.4%, with 17 out of 18 evaluable patients achieving CR.

The treatment was well-tolerated, showing no significant side effects, indicating that this combination therapy is both effective and safe for APL patients.

Arsenic trioxide (AT) has shown high efficacy in treating acute promyelocytic leukemia (APL), achieving complete remission in 80% to 90% of patients with refractory or relapsed cases, while being well tolerated at a dose of 0.15 mg/kg/d.

Common side effects include fatigue, rash, and QTc-interval prolongation, but ongoing research is exploring its combination with retinoic acid and potential use in other blood cancers and solid tumors.

The novel oral formulation ORH-2014 of arsenic trioxide was found to be safe and well-tolerated in a phase 1 study involving 12 patients with advanced hematologic malignancies, with no dose-limiting toxicities and only one instance of grade III QT prolongation that resolved after treatment interruption.

At a dose of 15 mg, ORH-2014 achieved comparable plasma concentrations to the standard intravenous arsenic trioxide, indicating it provides similar therapeutic exposure while being easier to administer, making it a promising candidate for future clinical trials.

Oral arsenic trioxide ORH-2014 pharmacokinetic and safety profile in patients with advanced hematologic disorders. Ravandi, F., Koumenis, I., Johri, A., et al.[2021]

Arsenic trioxide (ATO) showed a complete remission (CR) rate of 97.5% in 41 patients with acute promyelocytic leukemia (APL), which is comparable to the 93.3% CR rate seen with all-trans retinoic acid (ATRA) in 30 patients.

ATO therapy resulted in a significantly shorter median time to complete remission (29 days) compared to ATRA (38.5 days), and ATRA was associated with a high incidence of retinoic acid syndrome (52.9%), suggesting ATO may be a safer and more effective first-line treatment for APL.

Arsenic trioxide is a key treatment for acute promyelocytic leukemia and shows effectiveness against other leukemia types, but its side effects can limit its use, particularly in patients with complex symptoms.

Combining arsenic trioxide with other anticancer drugs, vitamins, and plant products can help reduce side effects and improve treatment outcomes, highlighting the need for careful clinical application to maximize benefits and minimize risks.
