Study summary

In this project, the investigators intend to start a prospective registry for patients with newly diagnosed Philadelphia-negative ALL from 16 years old and above in participating centers, provided that all patients will be treated with the same regimen (a pediatric regimen BFM-based incorporating peg-asparaginase). All diagnostic/follow-up (after induction and consolidation blocks) samples will be centrally biobanked at Instituto do Cancer do Estado de Sao Paulo. The main goal of this study is to examine whether the implementation of a pediatric protocol under a prospective registry can increase event-free survival (EFS) and overall survival (OS) of newly diagnosed patients in the participating centers.

Read the detailed description

Notably, pediatric regimens for adult acute lymphoblastic leukemia (ALL) have resulted in better long-term outcomes, especially in the Philadelphia-negative counterpart. These regimens are essentially based on higher cumulative doses of asparaginase and the use of less myelotoxic agents, applying allogeneic transplantation only for high-risk ALL subsets. Recent metanalysis encompassing 27 clinical trials demonstrated an improved prognosis when these regimens are adopted. In adults, incorporation of these regimens has been hampered by a perception of higher toxicity and a more complex design, especially with asparaginase. Remarkably, this drug might bring side effects not usually seen with other cancer drugs, such as thrombosis, liver, and pancreatic toxicities. In addition, the incorporation of minimal residual disease (MRD) monitoring throughout the treatment protocol in a scheduled and standardized manner is considered paramount in the contemporary ALL treatment. Treating adult patients with acute leukemia under prospective studies allows accurate data collection and positively impacts the disease prognosis, creating a cooperative scientific environment. In Brazil, few data are available on the clinical- laboratory characteristics of ALL in adults and their outcomes under a standardized treatment protocol. Few single-center reports point to a worse overall survival rate when compared to developed countries. There is great heterogeneity across the centers regarding the treatment regimens and genetic/MRD assessment. In this project, the investigators intend to start a prospective registry for patients with newly diagnosed Philadelphia-negative ALL from 16 years old and above in participating centers, provided that all patients will be treated with the same regimen (a pediatric regimen BFM-based incorporating peg-asparaginase). All diagnostic/follow-up (after induction and consolidation blocks) samples will be centrally biobanked at Instituto do Cancer do Estado de Sao Paulo. At the diagnosis, a genetic characterization encompassing conventional karyotype, fluorescent in-situ hybridization (FISH), and molecular biology in our central laboratory will be performed to classify the cases. Genomic classification will include identifying Philadelphia- like B-cell ALL cases, a recent group of cases with worse prognosis, whose incidence seems higher in Hispanics. In Brazil, there is no study addressing this incidence and, more importantly, evaluating its impact on outcomes under a standardized treatment protocol. MRD analysis will also be centralized to standardize and validate our flow cytometry panel in a homogeneous cohort. Additionally, the investigators plan to assess baseline factors predictive of survival and relapse and those related to major toxicities such as infections, liver toxicity, and thrombosis.

Study population

All patients from 16 years and above newly diagnosed with Philadelphia-negative ALL and after the signature of informed consent form (ICF). Patients between 16 and 17 years-old will sign a child assent along with a parental consent form. ICF application might be performed even under ALL suspicion only, given the need for sample collection before any therapy, ideally.

Eligibility criteria

Inclusion Criteria: Patients between 16 and 50 years-old with newly diagnosed ALL, negative for Philadelphia chromosome not previously treated (except for hydroxyurea, , or intrathecal chemotherapy) with 20% or more lymphoblasts in bone marrow or peripheral blood.

Exclusion Criteria:

  • Burkitt leukemia
  • Prior myeloproliferative disease
  • Philadelphia chromosome positivity through whichever methodology (RT-PCR, FISH, or conventional karyotype)
  • >2 (appendix 3)
  • Total >2x (ULN)
  • Transaminases>5x ULN
  • Creatinine>2,5 mg/dl
  • Positive serology for or HTLV
  • Heart failure Class III or IV (appendix 4)
  • Severe psychiatric disorder which prevents adequate compliance
  • Prior treatment with intravenous chemotherapy
  • Refusal to participate in the study
  • Down syndrome
Terms in these criteria, in plain language(6)

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
