Securing access to innovative anticancer therapies for children, adolescents, and young adults outside clinical trials: The SACHA study of the French Society of Pediatric Oncology (SFCE).

Abstract

10006 Background: Access to innovative anticancer therapies for children, adolescents and young adults within clinical trials in France is steadily increasing in the last years. However, current clinical trials portfolios are still inadequate and thus pediatric hemato-oncologists regularly prescribe innovative medicines outside their marketing authorization, and/or experimental drugs through compassionate use. Methods: The Secured Access to innovative medicines for CHildren with cAncer (SACHA) is a French prospective observational study developed by the French Society of Pediatric Oncology (SFCE) with Gustave Roussy as the legal sponsor to prospectively collect real-world safety and activity data of innovative therapies administered to patients ≤ 25 years-old with pediatric malignancies (solid tumor or leukemia) or other related conditions, either on compassionate use of experimental drugs or off-label use of anti-cancer medicines that have been first approved in adults after 2007. Prior to SACHA inclusion, multicenter tumor board discussion defining best available therapeutic options for each patient with a relapsed malignancy is mandatory. Results: The SACHA study opened in March 2020 and by February 2022, 283 patients have been included from 29/31 SFCE recruiting centers; median age: 11.0 years (range: 0.3-24.4). Main cancer types were central nervous system (CNS) tumors (47%), followed by non-CNS tumors (40%) and leukemias (13%). Innovative therapies prescribed in > 10 patients with reported objective response rate (ORR) and related CTCAE v.5 grade ≥2 clinical and/or grade ≥3 biological adverse drug reactions (ADRs) are described in Table. Conclusions: SACHA confirms the feasibility of this type of prospective real word registry, with a high participation of French centers. Based on this French experience, the Innovative Therapies for Children with Cancer (ITCC) consortium is currently developing a “SACHA International Project” to be opened in ITCC and collaborating countries.
