Detailed Description
This is a Phase Ib/II, open-label, multi-center study evaluating the safety, tolerability, efficacy, and PK/ Pharmacodynamics of APG-2575 in combination with Pd/DRd in patients with relapsed/refractory (RR) multiple myeloma (MM). The study consists of dose escalation and dose expansion phases. The study consists of will start with 2 arms noted below, both arms are independent.
Arm A: APG-2575 will be administered in combination with Pd to determine the MTD and /RP2D of APG-2575 in subjects with R/R MM.
3+3 design will be utilized in dose escalation phase of APG-2575 in combination with Pd. The starting target dose of APG-2575 is 400 mg (dose level; DL1) and will be escalated in subsequent cohorts to 600 mg (DL2), 800 mg (DL3) accordingly. Dose reduction to 200 mg (DL-1) is acceptable if APG-2575 at dose of 400 mg cannot be tolerated. This rule-based design proceeds with cohorts of three patients. If none of the three patients enrolled in DL1 experiences a DLT, another three patients will be treated at DL2, and so on. However, if one patient experiences a DLT, three more patients will be treated at the same dose level. The dose escalation continues until at least two patients among a cohort of three to six patients experience DLT. MTD is conventionally defined as the highest dose level at which ≤ 33% of patients experience DLT. Higher dose level would be considered after a comprehensive analyses of safety data in the context of 800 mg can be well tolerated, otherwise, 800 mg (DL3) should be considered as MTD (Arm A). RP2D (Arm A) will be determined based on efficacy and safety profile of APG-2575 in combination with Pd.
Patients will receive APG-2575 at target dose once daily for 28 days plus pomalidomide (4 mg ) on Days 1 through 21 and dexamethasone (40 mg for patients ≤ 75 years old or 20 mg for patients > 75 years old) on Days 1, 8, 15, and 22 of a repeated 28-day cycle

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- ≥ 18 years of age
MM patients (for Arm A and Arm B): Patients with Relapsed/Refractory MM per 2016 IMWG criteria, previously treated with at least 1 but not more than 4 prior lines of therapy for MM. Refractory MM, meanwhile, is defined as disease that progresses on salvage therapy or progresses within 60 days of the last treatment.
AL amyloidosis patients (for Arm C ONLY): Patients with AL amyloidosis when meeting:
i. histochemical diagnosis based on detection by polarizing microscopy of green birefringent material in Congo red-stained tissue specimens, the type must have been confirmed unequivocally.
ii. have symptomatic organ involvement. Only purpura and/or carpal tunnel syndrome are not acceptable.
iii. have at least one prior line of systemic therapy for AL. Patients who do not achieve at least a PR to frontline therapy in 3 months are eligible.
iv. All MM/AL patients should have measurable disease of AL amyloidosis as defined by at least ONE of the following:
- Serum monoclonal protein ≥1.0 g/dl by protein electrophoresis
- >200 mg of monoclonal protein in the urine on 24-hour electrophoresis
- Serum differential FLC concentration (dFLC, difference between amyloid forming [involved] and nonamyloid forming [uninvolved] free light chain [FLC]) > 5 mg/dL; OR serum FLC of 7.5 mg/dL provided the κ/λ FLC ratio is abnormal (κ/λ <0.26 for patients with monoclonal λ FLC, κ/λ >1.65 for patients with monoclonal κ FLC).

- Platelet count ≥ 50 x 10^9/L without transfusion support within 7 days of the first dose of study drug (for MM patients); or platelet count ≥ 100 x 10^9/L or ≥ 50 x 10^9/L if bone marrow involvement independent of transfusion support in either (for AL amyloidosis patients).
Adequate hepatic and renal function defined as:
- AST and ALT < 3 x upper limit of normal (ULN)

- Female subjects who are of non-reproductive potential (i.e., post-menopausal by history: no menses for ≥2 year; or history of hysterectomy; or history of bilateral tubal ligation; or history of bilateral oophorectomy). Female subjects of childbearing potential must have a negative serum pregnancy test upon study entry.
