BI 894999

Boehringer Ingelheim

This study is open to adults with different types of advanced cancer (solid tumours). The study is also open to patients with diffuse large B-cell lymphoma in whom previous treatment was not successful. In some countries, adolescents who are at least 15 years old and who are diagnosed with NUT carcinoma can also participate. No standard treatment exists for this rare and aggressive form of cancer.

The purpose of this study is to find out the highest dose of BI 894999 that people can tolerate.

BI 894999 is tested for the first time in humans. Participants take tablets once daily. The study also tests whether participants can tolerate BI 894999 better when taken continuously or with breaks in between.

Participants can stay in the study as long as they benefit from the treatment and can tolerate it.

The doctors also regularly check the general health of the participants.

OR was defined as best overall response (BOR) of complete response (CR) or partial response (PR) with tumour assessment during treatment period for each schedule.

For DLBCL patients, a minor response according to Response Evaluation Criteria In Lymphoma 2017 (RECIL 2017) was not part of an objective response.

BOR was determined from first treatment administration until the earliest of disease progression, death or last evaluable tumour assessment before start of subsequent anticancer therapy, loss to follow-up or withdrawal of consent, according to the following criteria depending on the type of cancer:

* solid tumour patients and mCRPC patients with measurable disease: CT and/ or MRI according to RECIST v1.1, every 2 cycles;
* mCRPC patients without measurable disease: bone scan and PSA level according to Prostate Cancer Clinical Trials Working Group 3, every 4 cycles;
* DLBCL patients:FDG-PET/CT scans according to RECIL 2017; every 2 cycles.

Progression-free survival (PFS) was defined as the time from date of start of BI 894999 to the date of objective disease progression ((PD) defined as 20% increase in the sum of the longest diameter of target lesions) or death, whichever is earlier for SCLC patients, CRC patients, mCRPC patients with measurable disease by Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) and NC patients, with tumour assessment every 2 cycles according to RECIST v1.1 during treatment period or Radiological PFS with tumour assessment by bone scan every 4 cycles for mCRPC patients with non-measurable disease by RECIST v1.1.

For patients with 'event' as an outcome for PFS:

- PFS \[days\] = date of outcome - date of first treatment administration + 1.

For patients with 'censored' as an outcome for PFS:

- PFS (censored) \[days\] = date of outcome - date of first treatment administration + 1.

The Kaplan-Meier method was used to calculate the estimates.

Best overall response (BOR) was determined from first treatment administration until the earliest of disease progression, death or last evaluable tumour assessment before start of subsequent anticancer therapy, loss to follow-up or withdrawal of consent, according to the following criteria depending on the type of cancer:

* solid tumour patients and mCRPC patients with measurable disease: Computerized tomography (CT) and/ or magnetic resonance imaging (MRI) according to RECIST v1.1, every 2 cycles;
* mCRPC patients without measurable disease: bone scan and PSA level according to Prostate Cancer Clinical Trials Working Group 3, every 4 cycles.

Overall survival (OS) was defined as the time from first administration of BI 894999 until death from any cause in patients with NUT carcinoma.

For patients with 'event' as an outcome for OS:

- OS \[days\] = date of outcome - date of first treatment administration + 1.

For patients with 'censored' as an outcome for OS:

- OS (censored) \[days\] = date of outcome - date of first treatment administration + 1.

The Kaplan-Meier method was used to calculate the estimates.

PSA response was defined as a decline in PSA value ≥50% from baseline (which is confirmed by a second value 3 to 4 weeks apart).

Phase Ia and Phase Ib: Area Under the Concentration-time Curve of BI 894999 in Plasma at Steady State Over a Uniform Dosing Interval τ (AUCτ, ss)

Adult patients diagnosed with NUT carcinoma (NC) were administered during the first cycle 2.5 milligram (mg) BI 894999 according to Schedule B and then the dosage was decreased at steady state to 2 mg of BI 894999 once daily, in the morning, after an overnight fast, 1 hour before breakfast with at least 250 milliliter (mL) of water. Schedule B was a continuous intake for 14 days followed by one week off treatment in cycles of 21 days.

Adult patients diagnosed with NUT carcinoma (NC) who were administered orally once daily on Day 1 and on Day 15 of each cycle a loading dose of 6 milligram (mg) of BI 894999, followed by six days intake of the maintenance dose of 3 mg of BI 894999 once daily, followed by one week off, repeated every two weeks in cycles of 28 days (Schedule C).

Phase Ib: Best Overall Response

Patients in NC Schedules B and C in Phase Ib dose expansion and after approval of protocol version 11.0 and gave consent to the collection of overall survival status.

For "Phase Ib - Schedule C: 6/3 or 7/3.5 mg BI 894999 (NC patients)" arm, the dose was lowered since DMC reclaimed the MTD as 6/3mg on 08Jul2020 after 1 patient already treated with 7/3.5mg, so the first patient in NC and all the following patients were treated with 6/3mg.

Phase Ib: Overall Survival

mCRPC Schedule B in Phase Ib dose expansion (mCRPC): Included all mCRPC patients in the treated set who were treated in Phase Ib with Schedule B.

For "Phase Ib - Schedule B: 2 or 2.5 mg BI 894999 (mCRPC patients)", DMC decided on 28Nov2018 to lower the dose of mCRPC due to safety concern, thus patients treated prior the decision received 2.5mg BI 894999 and patients treated after the decision received 2mg.
