Study summary

This is a multicenter, randomized, open-label, pragmatic low intervention clinical trial comparing high intensity reinduction chemotherapy with low intensity therapies in 1st or 2nd relapse Acute Myeloid Leukemia. The study is funded by European Commission (HORIZON-MISS-2022-CANCER-01-03, Project ID 101104421)

Read the detailed description

Thanks to recent advantages and results that demonstrate that low-intensity rescues may be quantitatively comparable to chemotherapy, novel personalized therapies are being slowly integrated into the treatment options of R/R AML. These new strategies, for the high interpatient variability, for the different cross-country reimbursement, for the school of thinking of treatment physicians, will wait decades to be proficiently compared with standard chemotherapy in the R/R setting, especially because most of the novel drugs are being pushed by the companies in the front-line (a setting that still has a large room for improvements). In IMPACT-AML RPCT, low-intensity therapies will be compared with high intensity chemotherapy rescue following a pragmatic, clinical-oriented approach. The study is funded by European Commission (HORIZON-MISS-2022-CANCER-01-03, Project ID 101104421)

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Non-Acute promyelocytic leukemia (APL) AML defined according World Health Organization (WHO) 2022 (or International Consensus Classification (ICC) 2022) criteria
  • 1st or 2nd relapse or according to European leukemia Network (ELN) 2022
  • Patient is clinically candidate to both low intensity therapy and high dose chemotherapy in the opinion of the physician
  • Both low intensity therapy and high dose chemotherapy to which patient is candidate are available and can be provided as per local practice
  • No specific treatment protocol can be rationally considered better suited to patient needs.This specifically include, but is not limited to:

    i) the availability of a drug that is already demonstrated superior to comparator arm and can be considered the only standard of care ii) specific related to fitness or any medical conditions that deem to avoid one of the two arms of this randomization iii) patient willingness to avoid one of the two arm of this randomization iv) lack of social support that make unfeasible one of the two arm of this randomization

  • Male or Female, aged>18 years
  • (ECOG) performance status \<4
  • A female participant is eligible to participate if she is not pregnant and not breastfeeding. If Women of (WOCBP), negative serum pregnancy test within 14 days of starting treatment must be obtained. WOCBP must adopt highly effective methods, according to guideline "Recommendation related to contraception and pregnancy testing in clinical trials". Male patient and his female partner who is of childbearing potential must use 2 methods of birth control (a condom as a barrier method of contraception and one of the highly effective birth control methods, according to guideline "Recommendation related to contraception and pregnancy testing in clinical trials". Use of- and compliance to- birth control methods are required beginning at the screening visit and continuing until 6 months following last treatment with study drug.
  • Participant is willing and able to give for participation in the study

Exclusion criteria

Exclusion Criteria:

  • Known to the study drug that will be selected by the treating physician within the list of high or low intensity treatment, according to most update version of Summary of Product Characteristics (SmPC) (e.g. , allergy, organ failure precluding treatment)
  • Participation in another clinical trial with any agents within 14 days or 5 drug half-lives (whatever comes first) prior to randomization
  • Active infections or other clinical conditions that in the opinion of the investigator make the patient ineligible to receive study treatment.
Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
