About
The study is intended to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of AZD4512 in patients with relapsed/refractory B-Cell acute lymphoblastic leukemia (r/r B-ALL).
Full description
In this Phase I/II, open-label multi-center study AZD4512 will be administered to adult/young adult patients (Module 1: >=16 years; Module 2: >=12 years) with relapsed/refractory B-Cell acute lymphoblastic leukemia (B-ALL). This study will have 2 parts: Module 1 - Dose Escalation and Module 2 - Dose Optimization.

Inclusion criteria
-
1. Age:
-
16 years old in Module 1
-
12 years old in Module 2
2. Diagnosis: Known Diagnosis of CD22-positive B-ALL based on criteria established by WHO (Alaggio et al. 2022).
-
-
Participants must have relapsed or refractory B-ALL ('relapsed' defined as bone marrow blasts > 5% or reappearance of blasts in PB)
-
Module 1 (DE): Ph(-) B-ALL and Ph(+) B-ALL - R/R
-
Backfill of Module 1 and Module 2 (DO): R/R Ph(-) B-ALL (BM blasts >5%)
3. Performance status (ECOG ≤ 2; KPS ≥ 50; LPS ≥ 50)
4. Peripheral lymphoblast count < 10,000/µL (may receive cytoreduction prior to C1D1 per protocol-specified criteria)
5. At least 2 prior therapies with refractoriness or relapse, or 1 prior therapy with refractoriness or relapse and no standard options available. Participants who have received prior CD22 targeted therapies are eligible.
-
Ph+ B-ALL (Module 1 DE only): intolerant to or have contraindications to TKI therapy or R/R disease despite treatment with at least 2 prior TKIs or at least one 3rd generation TKI
6. Prior DLI >4 weeks, prior cell therapy or autoHSCT >8 weeks, alloHSCT >12 weeks
Exclusion criteria
-
Burkitt lymphoma and leukemia
-
Isolated extramedullary disease; Active testicular or CNS (> CNS1) involvement
-
Unresolved non-heme toxicities Grade ≥ 2 (except alopecia, stable Grade ≤ 2 neuropathy, vitiligo, endocrine disorders controlled with therapy)
-
History of drug-induced non-infectious ILD/pneumonitis requiring oral or IV steroids or supplemental oxygen or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening
-
Prior/concomitant therapy
- Cytotoxic treatment within 14 days (except ALL maintenance medications or cytoreduction)
- Biologic (immuno-oncology) treatment within 28 days or 5 half-lives (whichever is shorter)
- Non-CNS radiation within 2 weeks & CNS radiation within 4 weeks
- Medications known to prolong QTc and/or associated with Torsades de Pointes within 21 days or 5 half-lives (whichever is longer)
- Strong inhibitors of CYP 3A4 within 21 days or 5 half-lives (whichever is longer)
- Investigational agents or study interventions in the last 30 days or 5 half-lives prior to the first dose of AZD4512 whichever is longer. If the investigational product is an agent to treat B-ALL and meets the modality criteria, then a specific washout period must be adhered to instead.
