CHICAGO – Follow-up out to as long as 11 years from treatment confirmed the long-term efficacy and safety of myeloablative autologous stem cell transplantation for patients with severe scleroderma.
This extended follow-up comprised 43 survivors from the 75 patients originally randomized in a controlled, 6-year trial. Follow-up showed that, among the patients who underwent myeloablation and autologous transplant with hematopoietic stem cells, there were no long-term deaths or cancers, there was an 88% survival rate, and 92% remained off disease-modifying treatment, Keith M. Sullivan, MD, said at the annual meeting of the American College of Rheumatology.
Long-term survival among patients randomized to the study’s control arm, who received treatment with cyclophosphamide, was 53%.
Patients with severe scleroderma with significant internal organ damage who “are improved and off of disease-modifying antirheumatic drugs after 10 or more years from treatment is something new in autoimmune disease,” said Dr. Sullivan, a professor of medicine at Duke University, Durham, N.C.
Based on accumulated data from this randomized trial and other studies, the American Society for Blood and Marrow Transplantation issued a position statement in June 2018 that endorsed autologous hematopoietic stem cell transplantation as “standard of care” for systemic sclerosis (Biol Blood Marrow Transplant. 2018 June 25. doi: 10.1016/j.bbmt.2018.06.025), Dr. Sullivan noted in a video interview.
The SCOT (Scleroderma: Cyclophosphamide or Transplantation) trial randomized 75 patients with severe scleroderma and substantial internal organ involvement to receive treatment with either cyclophosphamide or myeloablative radiation followed by immune reconstitution with an autologous hematopoietic stem cell transplant. The trial’s primary endpoint, the global rank composite score at 54 months, showed the superiority of transplantation over standard treatment (N Engl J Med. 2018 Jan 4;378[1]:35-47).
Dr. Sullivan and his associates ran their long-term follow-up study on 43 of these 75 patients (25 from the transplanted group and 18 controls), excluding 21 patients who died during the original study, 4 additional patients from the control arm who died following the end of the original SCOT protocol, and 7 patients either lost to follow-up or who refused to participate in follow-up. Among the 25 transplanted patients, none died during the extended follow-up, 2 experienced cardiac failure, and 23 remained off of any disease-modifying antirheumatic drugs. Among the 18 survivors in the control arm, 3 had cardiac failure, 3 had respiratory failure, and 7 were on treatment with disease-modifying drugs, Dr. Sullivan reported.
In addition, 23 of the 25 (92%) transplanted patients had normal performance status by the Eastern Cooperative Oncology Group criteria, compared with 11 of the 18 controls (61%). A total of 14 (56%) transplant patients were employed, compared with 6 of the 18 controls (33%).
Patients who were transplanted “have their life back, are doing well, and are off treatment,” Dr. Sullivan noted.
Myeloablation and transplant is appropriate for scleroderma patients with significant internal organ involvement, about half of all patients with this disease. The best gauge of severe organ involvement is a pulmonary function test, with a forced vital capacity of 70% or less of predicted as a flag for patients who should consider transplantation, Dr. Sullivan said. He recommended monitoring lung function every 3 months in scleroderma patients because it can deteriorate very suddenly and quickly.
SCOT received no commercial funding. Dr. Sullivan had no disclosures to report.
