Darolutamide
DASL-HiCaP Study

SUMMARY

  • The DASL-HiCaP study is an ongoing phase 3, randomized, double-blind, placebo-controlled, multicenter study (N=1106) evaluating the use of darolutamide (n=553) vs placebo (n=553), both in combination with androgen deprivation therapy (ADT) and primary or salvage radiotherapy (RT) in patients with very high-risk localized prostate cancer defined by the study criteria.1,2 Pelvic nodal RT was given to all patients regardless of the pelvic lymph node status.

  • Baseline characteristics were generally well balanced between patients who received darolutamide and those who received placebo in both the overall population and in the primary and salvage RT cohorts.

  • At the interim analysis in the darolutamide vs placebo groups, respectively:1

    • Darolutamide reduced the risk of metastases compared to placebo. The proportion of participants with metastasis-free survival (MFS) (primary endpoint) at 4 years was 95% vs 88% (hazard ratio [HR]: 0.42 [95% confidence interval (CI): 0.27-0.66]; p=0.0001). Of the 27 vs 63 patients who had an MFS event, 33% vs 73% developed metastases, and 67% vs 27% died without prior metastases.

      • In prespecified subgroup analyses of MFS according to randomization stratification factors and other baseline characteristics, darolutamide showed benefit vs placebo across most subgroups.

    • The proportion of participants who were event-free (EF) at 4 years (from baseline) for the secondary efficacy endpoints and post-hoc analyses were: prostate-specific antigen progression-free survival (PSA-PFS), 91% vs 83% (HR: 0.47 [95% CI, 0.33-0.67]); castration-resistant prostate cancer (CRPC), 99% vs 95% (HR: 0.22 [95% CI, 0.09-0.52]); subsequent hormonal therapy, 96% vs 90% (HR: 0.36 [95% CI, 0.21-0.60]); prostate cancer-specific survival (PCSS), 99% vs 99% (HR: 0.58 [95% CI, 0.17-1.97]); overall survival (OS), 97% vs 95% (HR: 0.88 [95% CI, 0.49-1.59]).
      • Subsequent therapies were administered to 4% and 10% of patients, primarily ADT (2% vs 8%) and ARPIs (2% vs 7%).
    • The incidence of adverse events of special interest (AESIs) was similar in both groups. The most frequent all-grade AEs, reported in >50% of patients in either group, were vasodilation and flushing (66% vs 64%) and fatigue/asthenic conditions (64% vs 57%). Reported AESIs were primarily grade 1-2.

DASL-HiCaP Study

 

Study Design/Methods

 

The DASL-HiCaP study (Darolutamide Augments Standard Therapy for Localised Very HighRisk Cancer of the Prostate; NCT04136353) is an ongoing phase 3, randomized, double-blind, placebo-controlled, multicenter study evaluating darolutamide in combination with ADT and primary or salvage radiotherapy (RT) in patients with very high-risk localized prostate cancer defined by the study criteria.1,2 Pelvic nodal RT was given to all patients regardless of the identified pelvic lymph nodes.

Patient Characteristics

 

  • A total of 1106 patients were enrolled between April 2020 and August 2023. Baseline characteristics were generally well balanced between patients who received darolutamide and those who received placebo in both the overall population and in the primary and salvage RT cohorts.

Efficacy – Interim Analysis

 

  • At the interim analysis, conducted following 87 MFS events, in the overall darolutamide + ADT + RT group and placebo + ADT + RT group, the difference of treatment exposure and RT dose was similar (≤2% difference).1 Patient exposure to study drugs and RT dose delivered are outlined in Table 3: Treatment Exposure.

  • The proportion of patients with metastasis-free survival (primary endpoint) by conventional imaging at interim analysis was significantly (p=0.0001) greater in the darolutamide + ADT + RT group vs placebo + ADT + RT group (Table 4: MFS at Interim Analysis; Figure 2: MFS).
    • In prespecified subgroup analyses of MFS according to randomization stratification factors and other baseline characteristics, darolutamide showed benefit vs placebo across most subgroups.

Safety – interim analysis

 

  • The incidence of adverse events of special interest (AESIs) was similar in both groups. The most frequent all-grade AEs, reported in >50% of patients in either group, were vasodilation and flushing and fatigue/asthenic conditions. Reported AESIs were primarily grade 1-2. AESIs are presented in Figure 3: AESIs.
