A Phase II, Open-Label, Study of Subcutaneous Canakinumab, an Anti-IL-1β Human Monoclonal Antibody, for Patients With Low or Int-1 Risk IPSS/IPSS-R Myelodysplastic Syndromes and Chronic Myelomonocytic Leukemia

What's the purpose of the trial?

This phase II trial studies how well canakinumab works for the treatment of low- or intermediate-risk myelodysplastic syndrome or chronic myelomonocytic leukemia. Canakinumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread.

A Phase 2 Study of Canakinumab in Patients with Lower-Risk Myelodysplastic Syndromes or Chronic Myelomonocytic Leukemia

Findings: Between August 2020 and May 2023, 27 patients were enrolled in the phase 2 portion of this study, and 2 patients failed screening. The median age was 74 years with 15 (60%) male patients; 20 patients (80%) were post-hypomethylating agent failure with a median number of prior lines of therapy of 2 (1-5). Transfusion dependency was observed in 24 patients (96%) prior to canakinumab initiation. Fourteen (56%) patients showed normal karyotype. IPSS-R stratification revealed an intermediate-2 risk in 12 (48%) patients and a high risk in one (4%). The most common mutations were SF3B1 (40%), TET2 (32%), DNMT3A (28%), and RUNX1 (24%). IPSS-M risk score was calculated for 24 cases showing one (4%) very low (VL), four (16%) low (L), 14 (16%) moderate low (ML), eight (32%) moderate high (MH), five (20%) high (H), and two (8%) very high (VH) risk categories. Canakinumab was well tolerated and no drug-related toxicities were observed. One death due to sepsis, which was deemed not treatment-related, occurred on the study drug. Out of 23 evaluable patients, the overall response rate was 17·4%, with erythroid and platelet hematological improvement (HI-E and HI-P, respectively) confirmed in 3 (13.0%) patients and 1 (4.3%) patient, respectively. Thirteen patients had stable disease (56·5%) and 6 (26·1%) progressed during therapy, 1 of which transformed to AML (Fig. 1). TI was achieved in 3 patients (median DoR 8·53 months (95% CI 0·41-16·1) and 2 of them maintained TI for over 12 months. With a median follow-up time of 22·6 months (95% CI 15·0-29·4), median OS was 17·3 months (95% CI 14·3-not estimable). We performed separate univariate analyses to evaluate any associations between the IPSS-M and OS/PFS. The median OS in patients with higher-risk MDS by IPSS-M (MH, H, VH) was 15·0 months vs 29·4 months in the lower-risk disease by IPSS-M (VL, L, ML) group (p=0·12). Interestingly, statistically significant findings were observed with 1-year PFS when stratifying patients into higher vs lower risk MDS by IPSS-M (64·3% vs 100·0%, respectively; p=0·022, Fig. 2).

Conclusion: In this cohort of MDS patients who had experienced multiple lines of prior therapy and exhibited high-molecular-complexity, canakinumab showed limited efficacy (HI 17.3%). Nevertheless, canakinumab showed a good safety profile and yielded sustained long-term responses in patients with single somatic driver mutation in TET2 or DNMT3A. This suggests that clonal complexity, and therefore disease burden, may be a determining factor in response to canakinumab. Therefore, we have amended the protocol of a phase 1/2 clinical trial evaluating the safety and activity of canakinumab in clonal cytopenia of unknown significance (CCUS) and low-molecular complexity MDS patients. Our results will clarify the role of IL-1β signaling in MDS initiation and progression.
