Acute Lymphoblastic Leukemia Lymphoblastic Lymphoma Biomarker Driven Clinical Trial Trametinib Chemotherapy Relapse Refractory Children Adolescents Young Adults

ClinConnect Summary

The HEM iSMART-D clinical trial is exploring a new treatment approach for children and young adults with certain types of blood cancers, specifically acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL), that have not responded to previous treatments or have returned after treatment. This trial is testing a combination of three medications—trametinib, dexamethasone, and chemotherapy drugs (cyclophosphamide and cytarabine)—to see if they can help patients whose cancer cells have specific changes in their genes.

To participate, patients must be between 1 and 20 years old, have a certain performance level, and their cancer must show specific genetic features related to the RAS-RAF-MAPK pathway. Participants will undergo regular health check-ups to monitor their response to the treatment and any side effects. This trial is currently recruiting, which means eligible patients can still join. It's important to note that there are several criteria that might exclude someone from participating, including having certain health conditions or recent treatments. If you think this trial might be an option, discussing it with a healthcare provider could provide more personalized information.

Eligibility criteria

  • Inclusion criteria
  • 1. Children between 1 year (≥ 12 months) and 18 years of age at the time of first diagnosis and less than 21 years at the time of inclusion. Patients under 6 years old must weigh at least 7 kg at the time of enrollment. Patients over 6 years old must weigh at least 10 kg at the time of enrollment.
  • 2. Performance status: Karnofsky performance status (for patients \>12 years of age) or Lansky Play score (for patients
  • 12 years of age) ≥ 50% (Appendix I).
  • 3. Written informed consent from parents/legal representative, patient, and age-appropriate assent before any study specific screening procedures are conducted, according to local, regional or national guidelines.
  • 4. Patients must have had molecular profiling and flow-cytometric analysis of their recurrent or refractory disease at a time-point before the first inclusion into this trial (see section 9.1 of this protocol for detailed description of the molecular diagnostics required). Drug response profiling and methylation is highly recommended but not mandatory.
  • Patients with molecular profiling at first diagnosis lacking molecular diagnostics at relapse or refractory disease may be allowed to be included after discussion with the sponsor.
  • 5. Patients whose tumor present RAS pathway activating mutations including but not limited to KRAS, NRAS, HRAS, FLT3, PTPN11, MAP2K1, MP2K1 hotspot mutations, cCBL; NF1 del, as detected by molecular profiling.
  • 6. Adequate organ function:
  • * RENAL AND HEPATIC FUNCTION (Assessed within 48 hours prior to C1D1) :
  • Serum creatinine ≤ 1.5 x upper limit of normal (ULN) for age or calculated creatinine clearance as per the Schwartz formula or radioisotope glomerular filtration rate ≥ 60 mL/min/1.73 m2.
  • Direct bilirubin ≤ 2 x ULN (≤ 3.0 × ULN for patients with Gilbert's syndrome).
  • Alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT) ≤ 5 x ULN; aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase/SGOT ≤ 5 x ULN. Note: Patients with hepatic disfunction related to the underling disease can be eligible even if they do not fulfill the aforementioned values for hepatic transaminases. In these cases, patients need to be discussed with the sponsor to confirm the eligibility.
  • * CARDIAC FUNCTION:
  • Shortening fraction (SF) \>29% (\>35% for children \< 3 years) and/or left ventricular ejection fraction (LVEF) ≥50% at baseline, as determined by echocardiography or MUGA.
  • Absence of QTcF prolongation (QTc prolongation is defined as \>450 msec on baseline ECG, using the Fridericia correction), or other clinically significant ventricular or atrial arrhythmia.
  • Exclusion Criteria
  • 7. Pregnancy or positive pregnancy test (urine or serum) in females of childbearing potential. Pregnancy test must be performed within 7 days prior to C1D1.
  • 8. Sexually active participants not willing to use highly effective contraceptive method (pearl index \<1) as defined in CTFG HMA 2020 (Appendix II) during trial participation and until 6 months after end of antileukemic therapy.
  • 9. Breast feeding.
  • 10. Impairment of gastrointestinal (GI) function or GI disease that may significantly alter drug absorption of oral drugs (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, or malabsorption syndrome) in case of oral IMPs.
  • 11. Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to the study drugs, or drugs chemically related to study treatment or excipients that contraindicate their participation, including conventional chemotherapeutics (i.e. cytarabine and cyclophosphamide, intrathecal agents) and corticoids.
  • 12. Known active viral hepatitis or known human immunodeficiency virus (HIV) infection or any other uncontrolled infection.
  • 13. Severe concomitant disease that does not allow treatment according to the protocol at the investigator's discretion.
  • 14. Subjects unwilling or unable to comply with the study procedures.
  • 15. Previous treatment with trametinib.
  • 16. Current use of a prohibited medication or herbal preparation or requires any of these medications during the study.
  • See Section 7 and Appendix III for details. Drugs inducing QTc changes (prolongation of the QT interval or inducing Torsade de Points) are not permitted.
  • 17. Unresolved toxicity greater than NCI CTCAE v 5.0 ≥ grade 2 from previous anti-cancer therapy, including major surgery, except those that in the opinion of the investigator are not clinically relevant given the known safety/toxicity profile of the study treatment (e.g., alopecia and/or peripheral neuropathy related to platinum or vinca alkaloid based chemotherapy) (Common Terminology Criteria for Adverse Events (CTCAE) (cancer.gov).
  • 18. Active acute graft versus host disease (GvHD) of any grade or chronic GvHD of grade 2 or higher. Patients receiving any agent to treat or prevent GvHD post bone marrow transplant are not eligible for this trial.
  • 19. Received immunosuppression post allogenic HSCT within one moth of study entry.
  • 20. History or current evidence of retina vein occlusion (RVO) or central serous retinopathy are excluded.
  • 21. Wash-out periods of prior medication:
  • 1. CHEMOTHERAPY: At least 7 days must have elapsed since the completion of cytotoxic therapy, with the exception of hydroxyurea, 6-mercaptopurine, oral methotrexate and steroids which are permitted up until 48 hours prior to initiating protocol therapy. Patients may have received intrathecal therapy (IT) at any time prior to study entry.
  • 2. RADIOTHERAPY: Radiotherapy (non-palliative) within 21 days prior to the first dose of drug. Palliative radiation in past 21 days is allowed.
  • 3. HEMATOPOIETIC STEM CELL TRANSPLANTATION (HSCT): Autologous HSCT within 2 months prior to the first study drug dose; Allogeneic HSCT within 3 months prior to the first study drug dose.
  • 4. IMMUNOTHERAPY: At least 42 days must have elapsed after the completion of any type of immunotherapy other than monoclonal antibodies (e.g. CAR-T therapy)
  • 5. MONOCLONAL ANTIBODIES AND INVESTIGATIONAL DRUGS: At least 21 days or 5 times the half-life (whichever is shorter) from prior treatment with monoclonal antibodies or any investigational drug under investigation must have elapsed before the first study drug.
  • 6. SURGERY: Major surgery within 21 days of the first dose. Gastrostomy, ventriculo-peritoneal shunt, endoscopic ventriculostomy, tumor biopsy and insertion of central venous access devices are not considered major surgery.
