What this study is testing
To assess hematologic response (VGPR or better i.e. dFLC < 40 mg/L, CR including modified CR, low-dFLC response (dFLC < 10 mg/L), iFLC < 10 mg/L) achieved after 6 cycles of Isa-Pd

Who can take part
You may be able to join if
- Age ≥ 18

In addition, a pregnancy test may be done at any time during the study at the discretion of the investigator if a subject misses a period or has unusual menstrual bleeding.
- Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
- Histologic diagnosis of AL amyloidosis;
- Patients should have received at least one line with an alkylating agent and/or a PI, and/or with an anti-CD38 which the last administration ≥ 1 year before the C1D1 and dexamethasone and not be in VGPR (or better) at the time of inclusion (patients who did not reach VGPR before, or patients in VGPR or better before but with a hematological relapse at the time of inclusion can be included);
- Measurable hematologic disease: difference between involved and uninvolved FLC > 50 mg/L with an abnormal k/l ratio;
You likely can't join if
- Presence of non-AL amyloidosis
- NT-proBNP > 8500 ng/L and hs-troponin I > 100 ng/L or hs-troponin T > 50 ng/L (cardiac stage IIIb patients)
- Repetitive ventricular arrhythmias on 24h Holter ECG despite anti‐arrhythmic treatment sustained ventricular tachycardia, aborted ventricular fibrillation, atrioventricular nodal or sinoatrial nodal dysfunction with no pacemaker
- Chronic atrial fibrillation with uncontrolled heart rate
- Significant cardiac dysfunction; myocardial infarction within 12 months; unstable poorly controlled angina pectoris
- Uncorrected valvular disease unrelated to AL amyloid cardiomyopathy

- Symptomatic organ involvement (heart, kidney, liver/GI tract, peripheral nervous system)
- Wash‐out period of at least 4 weeks from previous antitumor therapy or any investigational treatment or 5 half‐lives from previous antibodies, whichever is longer.
- Adequate bone marrow function prior to 1st drug intake (C1D1), without transfusion or growth factor support within 5 days prior to 1st drug intake, defined as: - Absolute neutrophils count ≥ 1000/mm3, - Platelets ≥ 75000/mm3, - Hemoglobin ≥ 8.0 g/dL,
- Adequate organ function defined as: - Serum ASAT and ALAT ≤ 3.0 X Upper Limit of the normal range (ULN), - Serum total bilirubin level < 1.5 x ULN, unless for subjects with Gilbert’s syndrome where the direct bilirubin should then be ≤ 2.0 x ULN.

What rules you out
- Presence of non-AL amyloidosis
- NT-proBNP > 8500 ng/L and hs-troponin I > 100 ng/L or hs-troponin T > 50 ng/L (cardiac stage IIIb patients)

- Chronic atrial fibrillation with uncontrolled heart rate
- Significant cardiac dysfunction; myocardial infarction within 12 months; unstable poorly controlled angina pectoris
- Uncorrected valvular disease unrelated to AL amyloid cardiomyopathy
- QT interval as corrected by Fridericia’s formula > 550 msec without pacemaker,

- Any clinically significant, uncontrolled medical conditions that, in the Investigator's opinion, would expose the patient to excessive risk or may interfere with compliance or interpretation of the study results
- Active systemic infection and severe infections requiring treatment with a parenteral administration of antibiotics
- Received any investigational drug within 14 days or 5 half-lives of the investigational drug prior to initiation of study intervention, whichever is longer. In case of very aggressive disease (i.e acute leukemia) delay could be shortened after agreement between sponsor and investigator, in absence of residual toxicities from previous therapy
- Undergoing dialysis
- Known positive for HIV or active hepatitis A, B or C: • Uncontrolled or active HBV infection: Patients with positive HBsAg and/or HBV DNA Of note: Patient can be eligible if anti-HBc IgG positive (with or without positive anti-HBs) but HBsAg and HBV DNA are negative. o If anti-HBV therapy in relation with prior infection was started before initiation of IMP, the anti-HBV therapy and monitoring should continue throughout the study treatment period. Patients with negative HBsAg and positive HBV DNA observed during screening period will be evaluated by a specialist for start of anti-viral treatment: study treatment could be proposed if HBV DNA becomes negative and all the other study criteria are still met. • Active HCV infection: positive HCV RNA and negative anti-HCV. Of note: Patients with antiviral therapy for HCV started before initiation of IMP and positive HCV antibodies are eligible. The antiviral therapy for HCV should continue throughout the treatment period until seroconversion. Patients with positive anti-HCV and undetectable HCV RNA without antiviral therapy for HCV are eligible
- Pregnant or breast-feeding females
- Ongoing toxicity (excluding alopecia and those listed in eligibility criteria) from any prior therapy > G1 (NCI-CTCAE v5.0)

- Hypersensitivity or history of intolerance to steroids, mannitol, pregelatinized starch, sodium stearyl fumarate, histidine (as base and hydrochloride salt), arginine hydrochloride, polysorbate 80, poloxamer 188, sucrose or any of the other components of study treatment that are not amenable to premedication with steroids and H2 blockers or would prohibit further treatment with these agents
- AL amyloidosis with isolated soft tissue involvement
- Bone marrow plasma cells >30% or symptomatic multiple myeloma
