What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests Calaspargase Pegol-mknl, a chemotherapy drug, in adult patients with newly diagnosed AML. It aims to find the safest effective dose by administering the drug through an IV to target cancer cells. Calaspargase Pegol-mknl is a newer chemotherapeutic agent used for treating acute lymphoblastic leukemia, similar to pegaspargase.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does mention that you cannot be on other investigational agents or concurrent chemotherapy or immunotherapy. Hydroxyurea is allowed for a short period before and after starting the trial treatment.

Is gemtuzumab ozogamicin safe for treating acute myeloid leukemia?

Gemtuzumab ozogamicin (GO) has been associated with serious side effects, including liver problems and infusion reactions. However, using a lower-dose schedule has shown fewer side effects like early death and liver issues, making it safer for some patients. ^{1 2 3 4 5}

What data supports the effectiveness of the drug Calaspargase Pegol-mknl, Inotuzumab Ozogamicin, Besponsa for treating acute myeloid leukemia?

Research shows that a similar drug, gemtuzumab ozogamicin, when combined with other chemotherapy drugs, improved survival rates and reduced the risk of relapse in patients with acute myeloid leukemia. This suggests that antibody-drug conjugates like Inotuzumab Ozogamicin, which is similar in nature, may also be effective in treating this condition. ^{1 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Calaspargase Pegol-mknl

Trial Overview The study tests Calaspargase Pegol-mknl as a chemotherapy agent for AML patients. It aims to find the highest dose patients can take without serious side effects (MTD) and decide on a recommended dose for future Phase 2 trials (RP2D).

Published Research Related to This Trial

Gemtuzumab ozogamicin (Mylotarg) has been approved for treating acute myeloid leukemia (AML) in patients aged 15 and older, showing significant improvements in event-free survival and reduced relapse risk based on a meta-analysis of 3,325 patients.

While Mylotarg is effective, it is associated with common side effects such as hemorrhage and infection, particularly when used in combination with other chemotherapy drugs like daunorubicin and cytarabine.

The EMA Review of Mylotarg (Gemtuzumab Ozogamicin) for the Treatment of Acute Myeloid Leukemia. Ali, S., Dunmore, HM., Karres, D., et al.[2020]

Gemtuzumab ozogamicin, when combined with daunorubicin and cytarabine, significantly improved event-free survival in adults with newly diagnosed CD33-positive acute myeloid leukemia (AML), with a median EFS of 13.6 months compared to 8.8 months for the standard treatment alone.

As a monotherapy, gemtuzumab ozogamicin also showed improved overall survival (4.9 months) compared to best supportive care (3.6 months), although serious side effects like hemorrhage and prolonged thrombocytopenia were more common with the combination treatment.
