Treatment advancements in chronic myeloid leukaemia (CML) have made the disease manageable but carry significant risk of side effects. Bridging information gaps between patients and physicians through shared decision-making (SDM) is increasingly favoured, yet understanding treatment complexities remains a challenge. This study sought to identify decisional and informational needs of both patients and physicians in CML care.

A qualitative study using semi-structured interviews was conducted to investigate the opinions, attitudes and preferences of both patients with chronic myeloid leukaemia and physicians.

Patients and physicians were recruited through the Dutch CMyLife platform, an initiative of haematologists, patients and patient organisations. They were provided with the participant information and invited to participate if interested.

A total of 15 interviews (n=10 patients, n=5 physicians) were conducted between April and October 2023.

A pre-defined interview guide was developed based on the Decisional Needs Assessment questionnaire. Interview transcripts were thematically analysed.

Eight themes and 28 sub-themes were observed, highlighting patient needs, treatment choices and informational preferences. Patients emphasised the importance of understanding medication options and side effects, while physicians stressed the necessity of delivering up-to-date and comprehensible information. Almost all participants had experienced professionals making the treatment decision, without patient involvement, especially when initiating treatment. Some patients expressed too little information and missed partnership with professionals at treatment onset. Peer support, decision-making dynamics and the role of caregivers were also significant considerations.

Both shared and distinct perspectives on CML treatment decision-making between patients and physicians were revealed, underscoring the complexity of decisional needs in CML management. The findings emphasise the importance of patient-centred care, SDM and tailored communication strategies to optimise patient outcomes and satisfaction. Improved communication and evidence-based decision-making tools can significantly impact patient well-being. Further research and interventions are necessary to address the challenges in decision-making processes in CML care.

Couples diagnosed with unexplained subfertility are advised to start mild ovarian hyperstimulation and intrauterine insemination (MOH-IUI) as a primary treatment. Natural feedback mechanisms and hormone release are affected by artificially stimulated cycles and induced ovulation. Additional luteal support could positively affect progesterone patterns in the luteal phase. The LUMO study evaluates whether the addition of exogenous progesterone in the luteal phase following MOH-IUI treatment cycle will improve pregnancy and live birth rates.

A multicentre randomised, double-blind, controlled trial will be conducted in Dutch fertility clinics, academic and non-academic hospitals. There are two treatment arms: group A progesterone luteal phase support; group B placebo, without crossover. All initiated MOH-IUI cycles within 6 months after randomisation are included (study period). Participants will start study medication, applying a daily dosage of 2dd 300 mg progesterone (Utrogestan) or 2dd 300 mg placebo in vaginal capsules on the second day after the IUI procedure. Treatment is continued until the onset of menstruation, a negative pregnancy test (IUI+14 days), a miscarriage or until 7 weeks of gestation in case of a viable pregnancy. Follow-up ends at 12 months after the end of study period (18 months after study randomisation). The primary outcome is cumulative pregnancy rate, achieved within 6 months after randomisation, leading to live birth. A total of 1008 patients (504 patients in each group) will be included.

The study was approved by the Central Committee on Research Involving Human Subjects on 30 January 2023. All participating sites have the approval of the local Board of Directors to participate in the LUMO study. An informed consent form will be signed by all participants. Study results will be presented at (inter)national conferences and published in peer-reviewed journals. It is expected that the results of this trial will be used to draft national guidelines on this issue.

The study is registered in the EU CTIS trial register (2022-501534-33-00), the Dutch trial registry (registration number: LTR 24508), ClinicalTrials.gov (NCT05080569) and the WHO registry (universal trial number: U1111-1280-9461).
