A Research Study Looking at Long-term Treatment With Etavopivat in People With Sickle Cell Disease or Thalassaemia
NCT06609226
Recruiting
Etavopivat is a new medicine under development for treating blood disorders like sickle cell disease and thalassaemia. Sickle cell disease and thalassaemia are inherited blood disorders that affect haemoglobin. Haemoglobin is the protein that carries oxygen through the body. This study is looking into how safe treatment with etavopivat is and how well it works over a long period of time. The study will last for up to 264 weeks, but it will end earlier if etavopivat is approved in the participant... Read More

Study of Lurbinectedin in Combination With Doxorubicin Versus Doxorubicin Alone as First-line Treatment in Participants With Metastatic Leiomyosarcoma
NCT06088290
Recruiting
The primary objective of this phase IIb/III study is to evaluate whether the combination of lurbinectedin plus doxorubicin given as first line treatment for metastatic leiomyosarcoma (LMS) prolongs the progression-free survival (PFS) by Independent Review Committee (IRC) when compared to doxorubicin administered as a single agent.

A Study of Intismeran Autogene (V940) Plus Pembrolizumab (MK-3475) Versus Placebo Plus Pembrolizumab in Participants With Non-small Cell Lung Cancer (V940-002)
NCT06077760
Recruiting
The goal of this study is to evaluate intismeran autogene plus pembrolizumab versus placebo plus pembrolizumab for the adjuvant treatment of margin negative, completely resected Stage II, IIIA, IIIB (with nodal involvement \[N2\]) non-small cell lung cancer (NSCLC). The primary hypothesis is that intismeran autogene plus pembrolizumab is superior to placebo plus pembrolizumab with respect to disease-free survival (DFS) as assessed by the investigator.
