Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Description of intervention(s) / exposure
SGR-1505 is an oral small molecule inhibitor of mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) and is intended for the treatment of mature non-Hodgkin B-cell lymphomas, with the primary indication in activated B-cell diffuse large B-cell lymphoma (ABC-DLBCL).
Investigational Product: SGR-1505
Dosage Formulation: Tablet
Route of Administration: Oral
Study consists of 3 parts:
Part A: study will evaluate the safety, tolerability, and PK of single ascending oral doses (SAD) of SGR-1505. Participants will enroll into each of the 6 SAD cohorts sequentially. All participants in the cohort will be evaluated for safety and tolerability before starting higher doses.
Cohort A1: Participants will receive a single dose of 25 mg of SGR-1505 on Day 1
Cohort A2: Participants will receive a single dose of 50 mg of SGR-1505 on Day 1
Cohort A3: Participants will receive a single dose of 100 mg of SGR-1505 on Day 1
Cohort A4: Participants will receive a single dose of 150 mg of SGR-1505 on Day 1
Cohort A5: Participants will receive a single dose of 200 mg of SGR-1505 on Day 1
Cohort A6: Participants will receive a single dose of 300 mg of SGR-1505 on Day 1
Part B of this study will evaluate multiple ascending oral doses (MAD) up to 10 days. Six participants will enroll into each of the 3 MAD cohorts. All participants in the cohort will be evaluated for safety and tolerability prior to initiating higher doses.
Part B will commence once the safety and tolerability of the 100 mg dose in Part A is established.
Cohort B1: Participants will receive once daily dose of 75 mg of SGR-1505 for 10 days.
Cohort B2: Participants will receive once daily dose of 150 mg of SGR-1505 for 10 days.
Cohort B3: Participants will receive once daily dose of 300 mg of SGR-1505 for 10 days.
Part D of this study will evaluate the effect of posaconazole (a CYP3A inhibitor) on the PK profile of SGR-1505. 200 mg SGR-1505 will be administered with a low dose of an antifungal drug called posaconazole in the fasted state.
Cohort D1: Participants will receive orally single dose of 200 mg of SGR-1505 on Day 1 and 18.
Participants will receive once daily single dose of 100 mg posaconazole on Day 9, Day 10, Day 11, Day 12, Day 13, Day 14, Day 15, Day 16, Day 17, Day 18, Day 19, Day 20, Day 21, Day 22, Day 23, Day 24, Day 25, Day 26.
Part D will start after the completion of cohort 5 in Part A
The subjects are domiciled at the Phase 1 unit and dosing administered and verified by the staff for all parts of the study.

Outcomes
Primary outcome [1] 333577 0
To assess the safety and tolerability of SGR-1505 following single and repeat doses in healthy participants.
To be assessed by monitoring
- The Incidence and severity of adverse events (AEs) . An assessment of AE severity will be performed according to the United States Food and Drug Administration (USFDA) Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials
- Clinical laboratory findings (Clinical Chemistry, Hematology, Coagulation): blood sample collection and analysis by pathology lab
- 12-lead Electrocardiogram (ECG)
- Vital sign measurements of (systolic/diastolic blood pressure - pulse rate -; body temperature - and respiratory rate using standard manual or electronic clinical procedures.
Timepoint [1] 333577 0
Part A: Adverse events (AE) will be monitored once daily from baseline to Day 10 post-dose administration
Part B: Adverse events (AE) will be monitored once daily from baseline to Day 11 post-dose administration
Part D: Adverse events (AE) will be monitored once daily from baseline to Day 27 post-dose administration
Secondary outcome [1] 417580 0
Part D: To assess the effect of posaconazole on the PK of SGR-1505 in healthy participants
Differences in PK parameters for SGR-1505 administered alone relative to the PK after multiple doses of posaconazole, includies area under the plasma drug concentration versus time curve (AUC0-t, AUC0-inf), maximum observed plasma drug concentration (Cmax), time to maximum observed plasma drug concentration (tmax), and apparent terminal half-life (t1/2).
Blood samples will be collected for PK analysis.
Timepoint [1] 417580 0
Part D: Day 1: predose, 30 minutes post-dose, 1, 2, 4, 8, hours post dose. Then once daily Day 2-8. Day 18: predose, 30 minutes post-dose, 1, 2, 4, 8, hours post dose. Then once daily - on Day 19-27
Secondary outcome [2] 417581 0
Part B: To assess dose proportionality of SGR-1505
Plasma sample will be collected for PK assessment.
AUC0-t, AUC0-8, and Cmax following single dose and AUC0-tau, AUC0-8,ss, and Cmax,ss following multiple doses for the assessment of dose proportionality.
Timepoint [2] 417581 0
Part B: predose, 30 minutes post-dose, 1, 2, 4, 8, hours post dose. Then once daily before study drug administration on Day 2-9. Day 10: predose, 30 minutes post-dose, 1, 2, 4, 8, and 24 hours post dose.
