Whole-genome and transcriptome sequencing of patients with advanced solid tumors enrolled in the NCT/DKTK MASTER (Molecularly Aided Stratification for Tumor Eradication Research) program revealed genetic alterations in a substantial proportion of patients including (i) alterations that lead to aberrant activation of BRAF, ERBB2, ALK, and the PI3K-AKT and MAPK pathways and (ii) changes that predict sensitivity to immune checkpoint inhibition, such as high tumor mutational burden and specific alterations of the PD-L1 locus.

Within this seven-arm basket phase II clinical trial, we aim to investigate the efficacy of targeted-therapy plus immune checkpoint inhibition in patients with advanced tumors exhibiting one of the following genetic alterations detected within the NCT/DKTK MASTER study: (i) BRAF V600E/K, (ii)ERBB2 amplification and/or overexpression or activating ERBB2 mutation, (iii) ALK rearrangement or activating ALK mutation, (iv) activating PIK3CA or AKT mutations or other aberration predicting increased PI3K-AKT pathway activity, (v) abberations predicting increased RAF-MEK-ERK pathway activity; (vi) patients with high tumor mutational burden and/or specific alteration predicting sensitivity to PD-1/PD-L1 inhibition are eligible within this study for immune checkpoint inhibition. Recruitment of adequate patient numbers into these well-defined molecular subgroup is achieved in a multicenter approach including NCT Heidelberg and NCT Dresden as well as DKTK partner sites. Eligible patients will be identified by in-depth molecular characterization of tumors within the NCT/DKTK MASTER program. All study arms are based on similar biometrical assumptions, and sample size as well as power calculations are based on Simon's optimal two-stage design for each study arm separately. The overall aim is to reduce the cumulative hazard of progression-free survival observed within the study (PFS2) compared to the cumulative hazard of the progression-free time before inclusion into the study (PFS1) using a paired log-rank test. The sample size of the entire trial varies according to the performance of the individual study arms, ranging between 98 and 175 patients.

Inclusion Criteria

Provision of written informed consent
Ability of patient to understand and comply with the protocol for the duration of the study, including treatment and scheduled visits and examinations
Diagnosis of a metastatic or locally advanced malignancy
Progressive disease
At least one measurable lesion that can be accurately assessed at baseline by computed tomography or magnetic resonance imaging and is suitable for repeated assessment
Prior administration of at least one standard chemotherapy for primary and/or relapsed malignancy according to current guidelines
ECOG Performance Status 2
Age 18 years, no upper age limit
Postmenopausal or evidence of non-childbearing status
Female patients of childbearing potential and male patients with partners of childbearing potential who are sexually active must agree to the use of two highly effective forms of contraception. These should be started immediately after signing the informed consent form and continued throughout the period of study treatment plus three months for female and for male patients thereafter
Availibility of complete information about the last medical treatment given before study participation, i.e. remission status before start of treatment, dosage and timing of drugs applicated, remission status and date of progression after treatment (in order to calculate PFS 1)
For patients included on the basis of molecular testing other than NCT/DKTK MASTER and for patients with an analysis in NCT/DKTK MASTER performed more than 3 months (date of tissue sampling) before planned study inclusion, a new tumor biopsy before start of study treatment is mandatory. However, patients may be included in the trial with archival tissue not older than 3 months on the basis of a case by case discussion with the PI
Arm-specific Inclusion Criteria as determined by Whole Genome Sequencing and
RNA Sequencing in NCT/DKTK MASTER or identification by gene panel performed in
a certified lab Eligibility for the trial and the respective trial arms will
be evaluated and determined exclusively by the NCT/DKTK molecular tumor board
on the basis of results from NCT/DKTK MASTER (for all arms) or of results from
other molecular studies, e.g. gene panel testing, performed in a certified
laboratory (for arms 1-6). Trial participation is only possible with a report
of the NCT/DKTK MASTER MTB confirming trial eligibility
Arm 1 (BRAF V600E/K): BRAF V600E/K mutation
Arm 2 (ERBB2): ERBB2 amplification/overexpression, activating ERBB2 mutation
Arm 3 (ALK): ALK rearrangement or activating ALK mutations including alternative transcription initiation (ALK-ATI) or RET-fusions
Arm 4 (PI3K-AKT): Activating PIK3CA or AKT mutations; other aberrations predicting increased PI3K-AKT pathway activity, e.g. PTEN loss
Arm 5: (PI3K-AKT-TAX): Activating PIK3CA or AKT mutations; other aberrations predicting increased PI3K-AKT pathway activity, e.g. PTEN lossa
Arm 6 (MAPK): Aberrations other than BRAF V600E/K predicting increased RAF-MEK- ERK pathway activity
Arm 7 (Immune evasion): High tumor mutational burden and/or specific alterations predicting sensitivity to PD1/PDL1 inhibition (e.g. DNA mismatch repair deficiency or PDL1 amplification and/or overexpression), ineligibility for the six specific arms
