BRAF V600E (and V600K) in cutaneous melanoma is the prototypical driver: combination BRAF + MEK inhibition (dabrafenib + trametinib; encorafenib + binimetinib; vemurafenib + cobimetinib) yields high ORR (~65-70%) and improves OS vs single-agent BRAFi (COMBI-d/v, coBRIM, COLUMBUS). Adjuvant dabrafenib + trametinib improves RFS in resected stage III (COMBI-AD). Triplet with anti-PD-1 (atezolizumab + vemurafenib + cobimetinib; IMspire150) extends PFS over doublet.dabrafenib + trametinib

BRAF V600K (~10-20% of BRAF-mutant melanomas) shares all BRAF/MEKi approvals with V600E. Slightly lower ORR in pooled analyses (COMBI-d/v subgroup) but PFS/OS benefit preserved. Companion-diagnostic kits (cobas, THxID) detect both V600E and V600K.dabrafenib + trametinib

Triggers from the patient profile that fired and drove the chosen branch.
Step 4 → branch 41
  • RF-MELANOMA-BRAF-V600-ACTIONABLE ★ winner: BRAF V600E or V600K activating mutation in metastatic / unresectable melanoma — ~40-50% prevalence cutaneous melanoma. Treatment-defining: BRAFi + MEKi doublet (dabrafenib + trametinib, encorafenib + binimetinib — COLUMBUS, vemurafenib + cobimetinib). Sequencing with anti-PD-1 (CheckMate-067, DREAMseq) — IO-first preferred in low-volume disease; BRAF+MEK first in symptomatic / high-LDH disease.

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity
Standard plan (IND-MELANOMA-2L-RELATLIMAB-NIVOLUMAB)
  • Do not prescribe if the patient already received anti-PD-1 1L — this buys nothing new beyond additional LAG-3 blockade with minimal benefit post-PD-1.
  • Do not ignore baseline troponin + ECG — myocarditis ~1.7% (higher than nivo mono); serial monitoring with symptoms.
  • Do not give >10 mg/day prednisolone before start — reduces ICI efficacy.
  • Do not use in baseline active autoimmune disease on systemic immunosuppression — irAE risk.
  • Do not confirm plan without verified funding pathway — relatlimab not registered in Ukraine; pathway = named-patient import.
  • Do not give live vaccines during or for 3 months after.
Standard plan (IND-MELANOMA-2L-KIT-IMATINIB)
  • Do not prescribe in KIT amplification without point mutation — non-predictive (Carvajal 2011).
  • Do not prescribe in non-mucosal/non-acral melanoma without NGS-documented KIT mutation — low pre-test probability + false-positives.
  • Do not continue >12 weeks without objective response (PR/CR) — early switch to ICI or BRAFi+MEKi if BRAF-co-mutated.
  • Do not forget off-label justification for MDT — imatinib is licensed for CML/GIST/Ph+ALL, not melanoma.
  • Do not ignore baseline + monthly LFTs — hepatotoxicity is a defined AE.
  • Do not give with warfarin without monitoring INR — CYP3A4 substrate interaction.
Standard plan (IND-MELANOMA-2L-POST-IO-BRAFI-MEKI)
  • Do not prescribe without verified BRAF V600E or V600K — non-V600 BRAF alterations do not respond to BRAFi+MEKi doublet.
  • Do not ignore baseline + serial ECHO (LVEF) — binimetinib cardiomyopathy ~7%, mandatory monitoring q2-3 mo.
  • Do not skip baseline + symptom-driven ophthalmology — RPED, RVO, uveitis class effect MEKi.
  • Do not use in BRAF-WT — toxic, ineffective; pseudo-paradoxical activation of MAPK in BRAF-WT cells.
  • Do not forget dermatology q3 mo — new SCC + primary melanomas class effect BRAFi (although less than vemurafenib mono).
  • Do not prescribe in IO-naive (without 1L anti-PD-1) — DREAMseq showed that IO-first sequence is superior to targeted-first for OS.
  • Do not confirm plan without verified funding pathway — ENCO+BINI out-of-pocket in Ukraine.
Aggressive plan (IND-MELANOMA-2L-POST-BRAFI-IPI-NIVO)
  • Do not prescribe in baseline active autoimmune disease on systemic immunosuppression — irAE can be fatal (myocarditis, hepatitis).
  • Do not ignore baseline TFTs, cortisol, LFTs, troponin — irAE monitoring is foundational.
  • Do not give >10 mg/day prednisolone before start — reduces ICI efficacy.
  • Do not continue ipi+nivo with Grade ≥3 irAE — switch to nivo maintenance or stop.
  • Do not prescribe in pre-BRAFi setting in BRAF V600+ — DREAMseq showed that IO-first gives better OS in BRAF-mut patients (exception: visceral crisis requires BRAFi for rapid response).
  • Do not give live vaccines during or for 3 months after completion.
