Medical Information

DARZALEX FASPRO - AMY3001 (ANDROMEDA) Study

Last Updated: 01/12/2025

SUMMARY

  • ANDROMEDA is a phase 3 study evaluating the efficacy and safety of DARZALEX FASPRO for subcutaneous (SC) use in combination with bortezomib, cyclophosphamide, and dexamethasone (D-VCd) compared to VCd alone in newly diagnosed patients with systemic immunoglobulin light-chain (AL) amyloidosis.1
    • Kastritis et al (2021)1 reported primary results of the study with a median follow-up of 11.4 months. The primary endpoint of hematologic complete response (CR) was achieved in 53.3% of the D-VCd arm vs 18.1% of the VCd arm, respectively (relative risk ratio, 2.9; 95% confidence interval [CI], 2.1 to 4.1; P<0.001). The most common all-grade treatment-emergent adverse events (TEAEs) occurring in >25% of patients in the D-VCd arm were diarrhea, peripheral edema, constipation, peripheral sensory neuropathy, fatigue, nausea, and upper respiratory tract infection.
    • Comenzo et al (2021)2 presented (at the 63rd American Society of Hematology [ASH] Annual Meeting & Exposition) updated efficacy and safety results of the ANDROMEDA study, with a median follow-up of 25.8 months. Hematologic CR rate was achieved by 60% of patients in the D-VCd arm vs 19% in the VCd arm (odds ratio [OR], 6; 95% CI, 3.8-9.6; P<0.0001). No new safety concerns were reported, except for 1 additional grade 3/4 TEAE (fatigue: D-VCd, 5%; VCd, 3%). The most common any grade TEAEs occurring in >20% of patients in the D-VCd arm were peripheral edema, diarrhea, constipation, fatigue, peripheral sensory neuropathy, nausea, insomnia, upper respiratory tract infection, anemia, and dyspnea. Deaths were reported in 17% (34/193) of patients vs 24% (45/188) of patients in the D-VCd arm vs VCd arm, respectively. There were no additional systemic ARRs reported.
    • Kastritis et al (2024)3 presented (at the 66th ASH Annual Meeting) results of the final analysis of major organ deterioration (MOD) progression-free survival (PFS) and overall survival (OS) from the phase 3 ANDROMEDA study with a median follow-up of 61.4 months. The final analysis confirmed that D-VCd substantially increased the rate of hematologic CR vs VCd alone (59.5% vs 19.2%; OR, 6.03; 95% CI, 3.80-9.58) and consistently resulted in a higher rate of hematologic response. D-VCd significantly improved MOD-PFS vs VCd alone. At a median follow-up of 61.4 months, the median MOD-PFS was not reached in the D-VCd arm and was 30.2 months in the VCd arm. MOD-PFS was observed in 79/195 vs 118/193 patients from the D-VCd vs VCd arm, respectively (hazard ratio [HR], 0.44; 95% CI, 0.31-0.63; P<0.0001). At a median follow-up of 61.4 months, D-VCd vs VCd significantly improved OS, despite crossover in >70% of VCd patients who received DARZALEX FASPRO as subsequent therapy (HR, 0.62; 95% CI, 0.42-0.90; P=0.0121). D-VCd vs VCd provided MOD-PFS and OS benefits across prespecified relevant subgroups. D-VCd was associated with 2 to 3 times higher cardiac and renal response rates vs VCd alone across study timepoints. Safety data were consistent with the known safety profiles of D-VCd and VCd.
    • Palladini et al (2020)4 reported safety run-in results of the ANDROMEDA study with a median follow-up of 17.6 months. Comenzo et al (2020)5 reported (at the 17th International Symposium of Amyloidosis [ISA]) updated safety run-in results with a median follow-up of 22.9 months (N=28). The primary endpoint of overall hematologic CR rate was achieved in 57% of patients and the overall response rate (ORR) was 96%. Administration-related reactions (ARRs) occurred in 7% (n=2) of patients, injection-site reactions (ISRs) occurred in 11% (n=3) of patients, and Grade 3/4 TEAEs occurred in 71% (n=20) of patients.
    • Palladini et al (2022)6 evaluated the results of the ANDROMEDA study as per the revised ISA criteria vs the original ANDROMEDA study criteria for CR with a median follow-up of 11.4 months. At month 3, the rate of hematologic CR was 31.3% vs 14% for ISA criteria and 38% vs 10.9% for ANDROMEDA criteria in the D-VCd vs VCd arm, respectively.
    • Other relevant literature has been identified in addition to the data summarized above.7-15

Efficacy
  • At 6 months, 179 of the 195 patients in the D-VCd arm had any type of hematologic response and 148 of 193 patients in the VCd arm. Efficacy data from the primary analysis are presented in Table: Summary of Overall Hematologic Responses in Primary Analysis (ITT Population).
  • The primary endpoint of hematologic CR was achieved by 53.3% of patients in the D-VCd arm vs 18.1% in the VCd arm, respectively.
  • The hematologic CR rate at 6 months was consistent with the overall hematologic CR rate: 49.7% in the D-VCd arm vs 14% in the VCd arm (OR, 6.1; 95% CI, 3.7-10; P<0.001).
  • Median time to CR was 60 days vs 85 days in the D-VCd arm vs the VCd arm, respectively.
  • At 6 months, renal progression was reported in 4.3% of patients in the D-VCd arm and 11.5% in the VCd arm.
  • At 6 months, cardiac progression was reported in 2.5% of patients in the D-VCd arm and 7.7% in the VCd arm.
  • Improvement in hematologic CR with D-VCd was consistent across subgroups
  • At 11.4 months, MOD-PFS was significantly better in the D-VCd arm compared to VCd alone (HR, 0.58; 95% CI, 0.36-0.93; P=0.02).
  • Major organ deterioration event-free survival (MOD-EFS), hematologic progression, or subsequent treatment was better in the D-VCd arm compared to VCd alone (HR 0.39; 95% CI, 0.27-0.56).

aBased on consensus criteria with clarifications as specified in the trial protocol that required confirmation by the independent review committee. Complete response was defined as negative immunofixation and normalization of the free light-chain ratio without confirmation, a reduction in the absolute involved free light-chain level to ≤20 mg/L, and a reduction in the dFLC to <10 mg/L.
bOf the 104 patients who had a hematologic complete response in the D-VCd arm, 4 patients died while in complete response and no patients with a complete response had a relapse. Of the 35 patients who had a hematologic complete response in the control arm, 2 patients died while in complete response and 2 patients had a relapse after a complete response.
cExcluded are 2 patients with an involved free light-chain level of ≤20 mg/L at baseline (both in the D-VCd arm).
dExcluded are 10 patients with a dFLC of less than 10 mg per liter at baseline (7 in the D-VCd arm and 3 in the VCd arm).

aRace was reported by the patient.
bECOG performance status was scored on a scale from 0 to 5, with 0 indicating no symptoms and higher scores indicating increasing disability.
cData are based on immunofixation and AL measurement.
dOther included the gastrointestinal tract, lungs, the peripheral nervous system, the autonomic nervous system, and soft tissues.
eCardiac stage was classified in accordance with the European modification of the staging system of Mayo Clinic. Cardiac stage was based on 2 biomarker risk factors—NT-proBNP and high-sensitivity cardiac troponin T—that were assessed at a central laboratory.
fAll patients had a cardiac stage of I, II, or IIIA at screening; however, some converted to stage IIIB at cycle 1, day 1 (results determined by the central laboratory were made available only after cycle 1, day 1).
gRenal stage was based on the combination of estimated GFR and urinary protein excretion.

Treatment Exposure and Subsequent Therapy
  • Treatment exposure and subsequent therapy details are presented in Table: Treatment Exposure and Subsequent Therapy.
    • A total of 25.9% vs 61.2% of patients from the D-VCd vs VCd arm, respectively, received subsequent therapy.3
    • A total of 71.3% (82/115) of patients from the VCd arm received subsequent DARZALEX FASPRO-based therapy.3
    • The most common reasons for DARZALEX FASPRO discontinuation included death (n=23), autologous stem cell transplant (n=12), and AEs (n=11).3
  • The median follow-up was 61.4 months.3

Efficacy
  • Efficacy data from the final analysis are presented in Table: Summary of Overall Hematologic Responses in the Final Analysis.
    • The median time to a hematologic CR was 67.5 vs 85 days for the D-VCd vs VCd arm, respectively.3
    • The final analysis confirmed that D-VCd substantially increased hematologic CR vs VCd alone (59.5% vs 19.2%; OR, 6.03; 95% CI, 3.80-9.58) and consistently resulted in a higher rate of hematologic response.3
  • D-VCd significantly improved MOD-PFS vs VCd alone.3
    • At a median follow-up of 61.4 months, the median MOD-PFS was not reached in the D-VCd arm and was 30.2 months in the VCd arm.
    • The estimated 60-month MOD-PFS rate was 60.2% vs 33.2% in the D-VCd vs VCd arm, respectively.
    • MOD-PFS was observed in 79/195 vs 118/193 patients from the D-VCd vs VCd arm, respectively (HR, 0.44; 95% CI, 0.31-0.63; P<0.0001).
      • Hematologic progression occurred in 41 vs 63 patients, MOD occurred in 3 vs 11 patients, and death occurred in 35 vs 44 patients from the D-VCd vs VCd arm, respectively.
    • Analyses of MOD-PFS rates in prespecified subgroups appeared to consistently favor D-VCd over VCd across relevant subgroups; the results are summarized in Table: MOD-PFS in Prespecified Subgroups.
    • Attaining hematologic and cardiac CR was associated with improved MOD-PFS in both patients with hematologic/cardiac CR and those with nonhematologic/noncardiac CR.
      • D-VCd vs VCd hematologic CR: HR, 0.57; P=0.1799.
      • D-VCd vs VCd nonhematologic CR: HR, 0.39; P=0.0004.
      • D-VCd vs VCd cardiac CR: HR, 0.34; P=0.073.
      • D-VCd vs VCd noncardiac CR: HR, 0.50; P=0.004.
    • Attaining cardiac CR was associated with improved MOD-PFS (HR, 0.23; 95% CI, 0.12-0.43) and OS (HR, 0.05; 95% CI, 0.01-0.19) rates.
  • At a median follow-up of 61.4 months, D-VCd vs VCd significantly improved OS, despite crossover in >70% of VCd patients who received DARZALEX FASPRO as subsequent therapy (HR, 0.62; 95% CI, 0.42-0.90; P=0.0121).3
    • The estimated 60-month OS rate was 76.1% vs 64.7% in the D-VCd vs VCd arm, respectively.
    • D-VCd vs VCd provided an OS benefit across prespecified relevant subgroups; results are summarized in Table: OS in Prespecified Subgroups.
  • D-VCd was associated with 2 to 3 times higher cardiac and renal response rates vs VCd alone across study timepoints; results are summarized in Table: Cardiac and Renal Responses in the Final Analysis.

Safety Run-in Results of ANDROMEDA

Palladini et al (2020)4 reported safety run-in results of the ANDROMEDA study with a median follow-up of 17.6 months. Comenzo et al (2020)5 reported updated safety run-in results of ANDROMEDA with a median follow-up of 22.9 months.

Study Design/Methods

  • At least 10 patients were to be enrolled in the safety run-in cohort to determine the safety and tolerability of DARZALEX FASPRO in combination with VCd.
  • If no safety signal is observed after ≥1 cycle of treatment, particularly regarding volume overload, approximately 360 patients are expected to be randomized 1:1 to receive VCd with or without DARZALEX FASPRO.
  • Key inclusion criteria: histopathological diagnosis of AL amyloidosis and measurable disease without prior therapy, ≥1 organ involvement, difference between involved and uninvolved free light chain (dFLC) ≥50 mg/L or M-protein ≥0.5 g/dL, and cardiac stage I to IIIA (European Modification of Mayo 2004). and an Eastern Cooperative Oncology Group (ECOG) performance status ≤2.
  • Key exclusion criteria: prior therapy for AL amyloidosis or multiple myeloma including medications that target CD38, previous or current diagnosis of symptomatic multiple myeloma, grade 2 sensory or grade 1 painful peripheral neuropathy, New York Heart Association (NYHA) stage IIIB or IV heart failure, or any form of non-AL amyloidosis.
  • Patients received either DARZALEX FASPRO + VCd or VCd alone as presented in the Kastritis et al (2021)1 Study Design/Methods section.
  • Patients were stratified as follows:
    • Cardiac stage (I vs II vs IIIA)
    • Transplant typically offered in local country (yes vs no)
    • Creatinine clearance (>60 mL/min vs <60 mL/min)
  • Primary endpoint: overall hematologic CR rate
  • Secondary endpoints: MOD-PFS, PFS, organ response rate as assessed by biomarkers, OS, improvement in patient-reported fatigue.

Outcomes Across Response Criteria in the ANDROMEDA Study

Palladini et al (2022)6 evaluated the results of the ANDROMEDA study as per the revised ISA criteria of CR vs the original ANDROMEDA study CR criteria at 3 and 6 months, respectively.

Study Design/Methods

  • As per the revised ISA criteria, CR was defined as negative serum and urine immunofixation and normal free light chain ratio (FLCr); however, an abnormal FLCr was not considered to preclude the achievement of CR when the uninvolved free light chain (uFLC) concentration is greater than the iFLC concentration.18
  • As per the original ANDROMEDA study criteria, CR was defined as negative serum and urine immunofixation, normal FLCr, and normal iFLC levels (normal uFLC level and normal FLCr were not required if the iFLC level was <upper limit of normal).1
  • Hematologic response was assessed using both the revised ISA criteria and the ANDROMEDA study criteria at 3 months and 6 months, respectively.

Results

  • At a median follow-up of 11.4 months, hematologic responses at 3 months and 6 months were similar between the ISA criteria and the ANDROMEDA study criteria. See Table: Hematologic Response in the ITT Population.
    • Rates of hematologic CR and ≥VGPR were higher in the D-VCd arm vs the VCd arm regardless of the criteria for CR applied.
  • The Cohen’s Kappa coefficient for hematologic response was 0.91 (95% CI, 0.88-0.94) at 3 months and 0.89 (95% CI, 0.86-0.93) at 6 months, indicating a strong concordance between the two criteria.
  • MOD-PFS and -EFS by hematologic response at 3 months and 6 months are presented in Table: MOD-PFS and -EFS by Hematologic Response at 3 Months and 6 Months.
