About this trial

Subjects with papillary craniopharyngioma harboring a BRAF mutation will be treated with a BRAF + MEK inhibitor (dabrafenib + trametinib) after informed consent. Study participants will be administered oral dabrafenib and trametinib until maximal tumor volume reduction assessed by MRI. Progression free survival, cognition, ophthalmologic status, hypothalamic status and quality of life will be assessed 1 year after initiation of study treatment

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Histologically verified papillary craniopharyngioma.

BRAF mutated V600E (valine 600 glutamine), verified immunohistochemically and by molecular genetic analysis

Newly diagnosed tumor, or recurrence after previous surgery, where surgery is not considered to be able to be performed radically without the risk of serious or permanent sequelae.

Age over 18 years

Disqualifiers

Ongoing treatment in another drug study or other experimental treatment.

Previous treatment with BRAF or MEK inhibitors.

Hypersensitivity to study drugs.

Ongoing treatment with non-authorized drugs, (strong inducers of CYP2C8 or CYP3A4). If the patient is on unauthorized drugs, they must be discontinued at least 14 days before inclusion.

Trial outcomes

Primary outcomes

1

Tumor response

To evaluate tumor response measured as maximally reduced tumor volume on MRI during treatment with dabrafenib and trametinib. Maximally reduced volume is defined as the time point where no further reduction of tumor volume can be observed

Time frame
1 month to 5 years (sliding timepoints)

Secondary outcomes

1

Response ratio

Response ratio according to RECIST

Time frame
1 year after initiation of study treatment
2

Response duration

Duration of response for patients treated without subsequent surgery

Time frame
From time of study drug discontinuation to time of observed increased tumor volume assessed up to 1 year
3

Operability after neoadjuvant trial treatment

Number of patients which become operable after neoadjuvant treatment

Time frame
1 year after initiation of study treatment
4

Progression-free survival 1 year

Defined as unchanged or diminished tumor volume

Time frame
1 year

Other outcomes

1

Levels of circulating mutated BRAF

BRAF assessed by plasma analysis and compared to baseline levels

Time frame
1 week after initiation of trial treatment
2

Levels of circulating mutated BRAF

BRAF assessed by plasma analysis and compared to baseline levels

Time frame
2 weeks after initiation of trial treatment
3

Levels of circulating mutated BRAF

BRAF assessed by plasma analysis and compared to baseline levels

Time frame
6 months after initiation trial treatment
4

Levels of circulating mutated BRAF

BRAF assessed by plasma analysis and compared to baseline levels

Time frame
12 months after initiation trial treatment
