Description of intervention(s) / exposure
Participants who consent to the study, will have a study-specific craniotomy and the tissue collected will be used to undergo molecular testing to identify mutations. The results of molecular testing will be reviewed by the LUMOS2 Molecular Tumour Advisory Board, and a treatment recommendation will be provided. If the participant is found to have a molecular profile that matches to one of the treatment arms available, they will be consented to and screened for the matched treatment arm. If the participant does not have a molecular profile that matches a treatment arm, they will be randomised to one of the treatment arms that does not require a matched mutation.

The following treatment arms are available under this protocol:
Arm 1 - Paxalisib: 45mg taken orally (capsule), once daily, for a 28 day cycle. If tolerated, after cycle 1 this will increase to 60mg daily.
Arm 2 - AK104: 6mg/kg as Intravenous injection, once every 2 weeks
Arm 3 - Selinexor: 80mg taken orally (tablet), once daily
Participants will continue to receive treatment until disease progression is documented or when the participants experience intolerable toxicity or withdraw for another reason.

Efficacy
Statistical methods / analysis
LUMOS2 is a multi-arm, phase 2, biomarker-directed, signal-seeking, umbrella clinical trial.
Prior studies in similar populations have shown 6-month Progression Free Survival (PFS) of approximately 36% (range 30-40%) and a rate lower than this would not be considered worthwhile. Nineteen participants will be recruited into each treatment arm, and have 80% power at 5% one-sided alpha to rule out a rate of 36% if the true rate is 65%, using a one-sample exact binomial test, and will allow estimation of 6-month PFS with a 95% confidence interval of maximum width ±21%.

Summary
Brief summary
This study aims to evaluate a new approach to the treatment of patients with lower grade glioma that has started to grow again (i.e. is recurrent) following your initial treatment.

Who is it for?
You may be eligible to join this study if you are aged 18 years or older, with histologically-confirmed grade 2 or 3 glioma at initial diagnosis, and with evidence of progressive disease after initial treatment.

Study details
For each participant, the study will involve taking a sample of tumour tissue during surgery, which will be screened for biomarkers. The results of this testing will then be used by a panel of experts who will make a treatment recommendation. If you have a mutation that matches one of the treatment arms, this will be recommended to you. If you do not have a mutation that matches one of the treatment arms, you will be randomised (i.e. allocated by chance) to one of the treatments that does not require a matching mutation. The study treatments available in LUMOS2 are: the oral medication Paxalisib administered once daily, the intravenous infusion AK104 administered once every 2 weeks, or the oral medication Selinexor administered once daily.
Treatment will continue until disease progression is documented or until participants experience intolerable toxicity or withdraw for another reason. During treatment, participants will undergo an MRI scan every 8 weeks to assess for disease progression and response to treatment, and will complete questionnaires regarding their quality of life.

It is hoped that screening tumour tissue for specific biomarkers to direct targeted treatment will be effective, safe, and cost-effective for the management of patients with recurrent lower grade glioma.
