Assess Efficacy & Safety of Selumetinib in Combination With Docetaxel in Patients Receiving 2nd Line Treatment for v-Ki-ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) Positive NSCLC

1. Is the biology right?

• Somatic driver evidence: yes · MAP2K1, MAP2K2, CSF3R in non-small cell lung carcinoma

  Rule: Open Targets has somatic-mutation evidence for the target in this cancer. Source: Open Targets: MAP2K1 in non-small cell lung carcinoma, 2026-11-11

  Published context: 2.3× relative success for targets with somatic (IntOGen) support in oncology (Minikel et al., Nature 2024, drug programs to 2023). A ratio between groups, not a probability for this program; mostly phase 2 to 3.
• Human genetic evidence: yes · MAP2K1: germline, somatic; MAP2K2: somatic; CSF3R: somatic

  Rule: Any germline or somatic human genetic evidence for the target in this cancer, counted apart from animal-model and literature evidence. Source: Open Targets: MAP2K1 in non-small cell lung carcinoma, 2026-11-11

  Published context: 2.6× relative probability of success, phase 1 to launch, with human genetic support (Minikel et al., Nature 2024, drug programs to 2023). All therapy areas, mostly germline evidence; not a probability for this program.
• Pediatric target: yes · MAP2K1, MAP2K2 on the FDA list

  Rule: Target is on FDA's Pediatric Molecular Target List (relevant targets); membership alone neither requires nor waives a study. Source: FDA Pediatric Molecular Target List (Listed as February 2026 on the FDA Pediatric Oncology page; the file served is 9.7.22_the_relevant_molecular_target_list.xlsx, whose Summary of Changes sheet is headed 'SEPTEMBER 2022 UPDATE' (footnote date 2022-09-01)), 2026-11-11
• Haematologic cancer: no · Solid tumour

  Rule: From the indication, or the registry conditions when no indication matches. Source: ClinicalTrials.gov NCT01933932, 2026-11-11

  Published context: Likelihood of approval from phase 1: 7.5% haematologic vs 4.6% solid (BIO / Informa / QLS 2021, 2011–2020). Population-level, not a prediction.

• MAP2K1 (via Selumetinib): Evidence types in non-small cell lung carcinoma: literature, genetic_association, somatic_mutation, clinical; literature listed separately from human genetics. Datasources: eva, clinical_precedence, intogen, cancer_gene_census, europepmc. · Open Targets: MAP2K1 in non-small cell lung carcinoma

2. Can the result be trusted?

• Randomised: yes · Randomised allocation

  Rule: Registry allocation field. Source: ClinicalTrials.gov NCT01933932, 2026-11-11
• Small denominator: no · 510 enrolled; each patient moves a rate by 100 ÷ 510 = 0.2 points

  Rule: Enrolment under 30; the arithmetic is shown, not a benchmark. Source: ClinicalTrials.gov NCT01933932, 2026-11-11
• Primary endpoint is overall survival: no · Progression-Free Survival (PFS)

  Rule: A registered primary outcome measure names overall survival. Source: ClinicalTrials.gov NCT01933932, 2026-11-11

  Published context: Non-OS primary endpoint: odds ratio 2.79 for a positive phase 3 (Otsuka 2021, 400 phase 3 oncology trials, to 2020). Shown with the next figure: a surrogate is easier to hit, and often a weak guide to survival.

  Published context: 52% of surrogate-to-OS correlations are low (Prasad 2015, published to 2014). Shown with the figure above.
• Results overdue: no · Results posted 2017-08-29

  Rule: Primary completion (actual) more than 12 months ago and no results posted to the registry. Source: ClinicalTrials.gov NCT01933932, 2026-11-11

3. What must it beat?

• Not loaded on this app yet: Control-arm result and approved therapies for the same segment, with label links. Source: Drugs@FDA, FDA labels and readouts (tickets 30, 32).

4. Too crowded, or too late?
