• Status: Recruiting
• Trial end date: 2022-02-28
• Target enrollment: 0

Summary

This Phase 1 Study is an open-label, non-randomized, dose escalation, safety, efficacy, pharmacokinetic, and pharmacodynamic evaluation study of INA03 administered as a single agent IV infusion every 2 weeks to patients ≥18 years of age with R/R AML, MLL, or ALL.

The study will be performed in 2 parts: a Dose Titration for Day 1 study (Part 1) followed by a Dose Escalation Part (Part 2) of INA03 used as monotherapy.

Criteria

Inclusion Criteria:

2. Total bilirubin level < 1.5 ULN (except Gilbert disease)

3. Serum creatinine ≤ 1.5 ULN

4. LDH < 3-5 ULN

5. Uric acid ≤8 mg/dl

6. Electrolyte panel within normal range

7. Urine Dipstick Reading negative for proteinuria or, if documentation of +1 results for protein on dipstick reading, then total urinary protein ≤ 500 mg and measured creatinine clearance ≥50mL/min/1.73m2 from a 24-hour urine collection

8. Patients who have recovered at least CTCAE grade <2 5. Life expectancy greater than 3 months 6. Women of child bearing potential must be willing to use birth control method during the study duration (W4 or early termination) plus 30 days. Male partner of women must use condom; in case of male patient, he must agree to use condom during the study duration (W4 or early termination) plus 30 days; 7. Pregnancy test (females of childbearing potential): negative 8. Signed informed consent indicating that they have been informed of the procedures to be followed, an is willing and able to comply the experimental nature of the therapy, alternatives, potential benefits, side effects, risks, and discomforts 9. Patient affiliated to the national "Social Security" regimen or beneficiary of this regi-men

Exclusion Criteria:

1. Patients with acute promyelocytic leukemia

2. Patients with more than 30% marrow erythroid cells

3. Patients who have been treated with any anti-TfR antibody

4. Allogeneic stem cell transplantation in the last 6 months or with persistent active GVHD. Autologous bone marrow transplant in the last 3 months

5. Last dose of prior chemotherapy, immunotherapy or investigational agent within 14 days or within 5 half-lives before baseline receipt of study medication, except for hydroxyurea and corticosteroids

7. Patients who have had a prior anaphylactic or other severe infusion reaction such that the patient is unable to tolerate human immunoglobulin or monoclonal antibody administration 8. Patients who have history or clinical evidence of central nervous system (CNS), meningeal, or epidural disease from any cause and/or peripheral neuropathy 9. Impaired cardiac function or clinically significant cardiac disease, including any one of the following:

a. New York Heart Association Class III or IV cardiac disease, including preexisting clinically significant arrhythmia, congestive heart failure, or cardiomyopathy b. Angina pectoris ≤ 3 months prior to starting study drug c. Acute myocardial infarction ≤ 3 months prior to starting study drug d. Other clinically significant heart disease (e.g., uncontrolled hypertension, history of labile hypertension, or history of poor compliance with an antihypertensive regimen) e. Left ventricular Ejection Fraction <45% 11. Uncontrolled infection 12. Acute and chronic liver disease 13. Other severe, acute, or chronic medical or psychiatric condition or laboratory abnor-mality that may increase the risk associated with study participation or study drug administra-tion or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for this study.

14. Patients with prior radiation therapy

1. ≤12 weeks for cranial radiation therapy

2. ≤ 4 weeks for wide field radiation therapy

3. ≤2 weeks for involved field radiation therapy 15. Major surgery ≤ 4weeks prior to starting study drug or who have not recovered from side effects of such therapy

16. Known diagnosis of HIV infection (HIV testing is not mandatory). 17. History of another primary malignancy that is currently clinically significant or currently requires active intervention 18. Pregnant or breastfeeding patient; 19. Active drug or alcohol dependence; 20. Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule.
