Single Center, open label, Phase I-II trial designed to test the safety and efficacy of the combination of Ataluren and Pembrolizumab for the treatment of metastatic mismatch repair deficient and proficient colorectal adenocarcinoma and metastatic mismatch repair deficient endometrial carcinoma.

In controlling tumor outgrowth an intact immune surveillance is very important. PD-1 receptor-ligand interaction is a major pathway hijacked by tumors to suppress this immune control.

Pembrolizumab is a potent and highly selective humanized monoclonal antibody designed to directly block the interaction between PD-1 and its ligands and is registered for the treatment of advanced (unresectable or metastatic) melanoma of locally advanced or metastatic NSCLC in adults. In an earlier study it's effect has been shown in mismatch repair deficient tumors.

Ataluren is designed to allow the protein making apparatus (the ribosome) in cells to skip over a premature stop codon (PTC), allowing the cells to translate the sequence downstream of a premature termination codon (PTC) in mRNA transcripts. This may result in the translation of additional out-of-frame code, which is available in abundance in dMMR tumors. We argue that this may result in new target peptides for the immune-system to recognize cancer cells.

The investigators hypothesize that the formation of these peptides by Ataluren can enhance the effect of Pembrolizumab anti-PD1 therapy.

Therefore the investigators designed a Single Center, open label, Phase I-II trial designed to test the safety and efficacy of the combination of Ataluren and Pembrolizumab for the treatment of metastatic mismatch repair deficient and proficient colorectal adenocarcinoma and metastatic mismatch repair deficient endometrial carcinoma.

In the phase-1 part of the study 2-4 groups of 3 patients each are treated with pembrolizumab 200mg i.v. q3w but with increasing ataluren doses (i.e. group1 25%, group2 50% and group3 100% of 10-10-20mg/kg). These can be either pMMR mCRC, dMMR mCRC or dMMR EC patients. The reported toxicity in phase-1 will be used to define the maximum tolerated dose (MTD) of the combination, that will determine the ataluren dose in phase-2.

In the phase-2 part of the study a dMMR group (cohort A, 20 patients either CRC of EC) and a pMMR group (cohort B, 15 CRC patients) will be treated with pembrolizumab 200mg i.v. q3w combined with ataluren t.i.d. at the MTD defined in phase-1.

To evaluate the safety and efficacy of the combination of an anti-PD-1 antibody (Spartalizumab (PDR001)), a BRAF inhibitor (dabrafenib) and a MEK inhibitor (trametinib) in unresectable or metastatic BRAF V600 mutant melanoma

This study is designed as a Phase III, multi-center study consisting of three parts:

* Part 1, known as the Safety Run-in, is an open-label part aimed at determining the recommended Phase III regimen (RP3R) of spartalizumab in combination with dabrafenib and trametinib for previously untreated subjects with BRAF V600 mutant unresectable or metastatic melanoma (Stage IIIC/IV per AJCC edition 7). In Part 1, spartalizumab was administered at a starting dose level (DL1) of 400 mg every 4 weeks (Q4W), along with fixed doses of dabrafenib (150 mg twice daily) and trametinib (2 mg once daily). The RP3R for Part 3 was determined using the Bayesian Logistic Regression Model (BLRM) with escalation with overdose control (EWOC) criteria.
* Part 2, referred to as the Biomarker Cohort, is an open-label section focused on characterizing the kinetics of immune biomarkers and potential immune resistance mechanisms. Part 2 started when the fourth subject in dose level 1 (DL1) of Part 1 completed approximately 4 weeks of study treatment, and fewer than 3 dose-limiting toxicities (DLTs) were observed. Participants in Part 2 receive PDR001 (spartalizumab) at a dosage of 400 mg Q4W, in combination with dabrafenib (150 mg BID) and trametinib (2 mg QD).
* Part 3 is a double-blind, randomized, placebo-controlled phase that compares the efficacy and safety of spartalizumab in combination with dabrafenib and trametinib to placebo in combination with dabrafenib and trametinib. Part 3 was initiated after determining the RP3R for the combination of spartalizumab with dabrafenib and trametinib in Part 1. Subjects were randomized in a 1:1 ratio to receive either the RP3R dose of spartalizumab identified in Part 1 or placebo, along with dabrafenib (150 mg BID) and trametinib (2 mg QD).

For all parts of the study, the treatment is continued until the subject experiences any of the following events: disease progression according to RECIST 1.1 as determined by the Investigator, unacceptable toxicity, initiation of a new anti-neoplastic therapy, pregnancy, withdrawal of consent, physician's decision, loss to follow-up, death, or termination of the study by the Sponsor. Safety evaluations are conducted for all subjects for up to 150 days after the last dose of spartalizumab/placebo (safety follow-up period).

Subjects who discontinue study treatment without disease progression as per RECIST 1.1 continue with tumor assessments according to the protocol until documented disease progression, withdrawal of consent, loss to follow-up, or death, regardless of the initiation of new anti-neoplastic therapy (efficacy follow-up period).

Subjects enter the survival follow-up period after completing the safety follow-up period or experiencing disease progression as per RECIST 1.1 or response criteria for immunotherapy, whichever period is longer (survival follow-up period).

Part 1 and Part 2 are open- label. Part 3 is double-blind and randomized.

Progression-free survival was defined as the time from the date of first dose to the date of the first documented radiological progression per investigator's assessment according to RECIST 1.1 or death due to any cause. The distribution of PFS was estimated using the Kaplan-Meier (KM) method. If a patient had not had an event at the time of data cut-off, progression-free survival was censored at the date of last adequate tumor assessment.

Overall survival is defined as the time from date of randomization to date of death due to any cause

ORR was defined as the percentage of subjects with confirmed best overall response of complete response (CR) or partial response (PR), as per investigator's assessment by RECIST 1.1.

CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \<10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters

DOR was defined as the time from first documented response of CR or PR to date of first documented progression or death, according to RECIST 1.1 criteria. The distribution of DOR was estimated using the KM method.

CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \<10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters

DCR was defined as the percentage of participants with CR or PR or subjects with stable disease (SD) lasting for a duration of at least 24 weeks as per local review according to RECIST 1.1 criteria.

CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \<10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters SD: Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progressive disease.

The EORTC QLQ-C30 was a 30-item questionnaire that patients complete, consisting of both multi-item scales and single-item measures. It included five functional scales, three symptom scales, six single items, and a Global Health Status/Quality of Life (GHS/QoL) scale.

The GHS/QoL scale had seven possible response scores ranging from 1 (very poor) to 7 (excellent), which were averaged and transformed to a 0-100 scale. A higher score on this scale indicated a better quality of life.

The change from baseline in GHS/QoL scores was calculated. A positive change from baseline indicated improvement in the patient's quality of life.

The EORTC QLQ-C30 was a patient completed 30 item questionnaire that was composed of both multi-item scales and single-item measures. These included five functional scales, three symptom scales, six single items and a global health status/QoL scale.

The EORTC QLQ-C30 physical functioning scale measured a patient's ability to carry out daily activities and tasks requiring physical exertion. It consisted of five questions asking patients to rate their level of physical functioning, with response options ranging from 1="not at all" to 4="very much". The scores for each item were summed and transformed to a 0 to 100 scale, with higher scores indicating better physical functioning.

The change from baseline in physical functioning scale scores was calculated. A positive change from baseline indicated improvement in physical functioning.

The EORTC QLQ-C30 was a patient completed 30 item questionnaire that was composed of both multi-item scales and single-item measures. These included five functional scales, three symptom scales, six single items and a global health status/QoL scale.

The EORTC QLQ-C30 pain symptom scale was one of the symptom scales in the questionnaire, which measured the severity of pain experienced by the patient. The pain symptom scale consisted of two items, one measuring the severity of pain and the other measuring the use of painkillers. The items were rated on a 4-point scale ranging from 1="not at all" to 4="very much". The scores for each item were summed and transformed to a 0 to 100 scale, with higher scores indicating more severe pain.

The change from baseline in pain symptom scale scores was calculated. A negative change from baseline indicated improvement.

The EORTC QLQ-C30 was a patient completed 30 item questionnaire that was composed of both multi-item scales and single-item measures. These included five functional scales, three symptom scales, six single items and a global health status/QoL scale.

The GHS/QoL scale had seven possible response scores ranging from 1 (very poor) to 7 (excellent), which were averaged and transformed to a 0-100 scale. A higher score on this scale indicated a better quality of life.

The time to definitive 10 point deterioration is defined as the time from the date of randomization to the date of event, which is defined as at least 10 points relative to baseline worsening of the GHS/QoL score or death due to any cause. If a subject had not had an event, the time to deterioration was censored at the date of the last adequate assessment. The distribution was estimated using KM method.

The Functional Assessment of Cancer Therapy-Melanoma (FACT-M) quality of life questionnaire was composed of the FACT-General (FACT-G) plus the Melanoma Subscale and the Melanoma Surgery Subscale, which complemented the general scale with items specific to quality of life (QoL) in melanoma.

The Melanoma Subscale of FACT-M included 16 questions, with response options of 0= "Not at all", 1= "a little bit", 2= "somewhat", 3= "quite a bit" and 4= "very much". The FACT-M melanoma subscale score ranged from 0 to 64, with higher scores indicating a higher quality of life in relation to melanoma.

The change from baseline in melanoma subscale scores was calculated. A positive change from baseline indicated improvement.

The EQ-5D-5L is a standardized questionnaire used to assess health-related quality of life, and it includes a Visual Analog Scale (VAS). The VAS score is obtained by asking the individual to rate their current health status on a scale from 0 to 100, where 0 represents the worst possible health state and 100 represents the best possible health state.

The change from baseline in EQ-5D-5L VAS score was calculated. A positive change from baseline indicates improvement in the health status.

PFS was defined as the time from the date of first dose to the date of the first documented radiological progression as per investigator's assessment using RECIST 1.1 response criteria or death due to any cause. The distribution of PFS was estimated using the KM method. If a patient had not had an event at the time of data cut-off, progression-free survival was censored at the date of last adequate tumor assessment.

PFS analysis was performed by PD-L1 status (positive, negative) where a positive status was defined as having ≥ 1% expression and a negative status was defined as having \< 1% expression.

OS is defined as the time from date of randomization to date of death due to any cause.

OS analysis will be performed by PD-L1 subgroup (positive, negative) where a positive status is defined as having ≥ 1% expression and a negative status is defined as having \< 1% expression.

Spartalizumab ADA prevalence at baseline was calculated as the percentage of participants who had an spartalizumab ADA positive result at baseline.

Spartalizumab ADA incidence was calculated as the percentage of participants who were treatment-induced spartalizumab ADA positive (post-baseline ADA positive with ADA-negative sample at baseline) and treatment-boosted spartalizumab ADA positive (post-baseline ADA positive with titer that is at least the fold titer change greater than the ADA-positive baseline titer)
