  1. Slide 1: Lifileucel (LN-144), a Cryopreserved Autologous TIL Therapy in Advanced Melanoma

    Lifileucel (LN-144), a Cryopreserved Autologous Tumor Infiltrating Lymphocyte (TIL) Therapy in Patients with Advanced Melanoma: Evaluation of Impact of Prior Anti–PD-1 Therapy James M. G. Larkin,1 Amod Sarnaik,2 Jason Alan Chesney,3 Nikhil I. Khushalani,2 John M. Kirkwood,4 Jeffrey S. Weber,5 Karl D

  2. Slide 2: Background

    Background • Currently, no treatment is approved for patients with advanced melanoma whose disease progresses while on or after treatment with ICI and BRAF/MEK inhibitors • In patients with advanced melanoma who are either primary refractory or develop resistance to ICI, retreatment with ICI or trea

  3. Slide 3: C-144-01 Study Design

    C-144-01 Study Design Phase 2, multicenter study to assess the efficacy and safety of autologous TIL (lifileucel) for treatment of patients with metastatic melanoma (NCT02360579) Cohort 1 Cohort 2 Endpoints Non-cryopreserved • Primary: Efficacy per investigator-assessed ORR using RECIST 1.1 TIL prod

  7. Slide 7: Objective Response Rate

    Objective Response Rate Response, n (%) N=66 • Mean number of TIL cells infused: 27.3 × 109 Objective Response Rate 24 (36.4) Complete response 3 (4.5) After a median study follow-up of 33.1 months, median DOR was not reached Partial response 21 (31.8) (range 2.2, 38.5+ months) Stable disease 29 (43

  8. Slide 8: Best Overall Response

    Best Overall Response 81% (50/62) of patients had a reduction in tumor burden 11 patients (17.7%) had further SOD reduction since April 2020 datacut *Patients with BRAF V600 mutation. 3 patients had no post-TIL disease assessment due to early death, and 1 due to start of new anticancer therapy. DOR,

  9. Slide 9: Time to Response for Evaluable Patients (PR or Better)

    Time to Response for Evaluable Patients (PR or Better) • 79% of responders received prior ipilimumab − 46% of responders received prior anti–PD-1 / anti–CTLA-4 combination • Responses continued to deepen over time − 1 PR converted to CR after 24 months post- lifileucel *BOR is best overall response

  10. Slide 10: Early and Sustained CR in a Patient with Multiple Failed Prior Therapies

    Early and Sustained CR in a Patient with Multiple Failed Prior Therapies Patient Narrative • 44-year-old male • Initial diagnosis in 2016 • Superficial spreading melanoma • Prior systemic therapies: − Ipilimumab + nivolumab − Dabrafenib + trametinib − TLR9 agonist + pembrolizumab − TVEC + pembrolizu

  11. Slide 11: Site of Tumor Resection and Infused Cell Dose

    Site of Tumor Resection and Infused Cell Dose Total Cell Dose Site of Tumor Resection R2=0.0248 Ratio CD4+ / CD8+ TIL R2=0.0074 Appropriate amount of TIL was manufactured Target lesion SOD reductions were seen across the range regardless of tumor resection site of total TIL cell doses and CD4+ / CD8

  12. Slide 12: Univariable Analyses: ORR of Lifileucel

    Univariable Analyses: ORR of Lifileucel ORR was not predicted by any patient or clinical characteristics analyzed, including: • Baseline LDH (≤ULN vs >ULN) • Baseline ECOG performance status (0 vs ≥1) • Baseline brain / liver lesions (yes vs no) • Cumulative duration on anti–CTLA-4 (≤median vs >medi

  13. Slide 13: Univariable Analyses: DOR of Lifileucel

    Univariable Analyses*: DOR of Lifileucel Although cumulative duration on prior anti–PD-1 / anti–PD-L1 was not associated with achieving a response to lifileucel (ORR), it was associated with DOR *Univariable Cox proportional hazards regression model was used to estimate hazard ratios with 95% confid

  14. Slide 14: Multivariable Model: Independent Predictors for DOR of Lifileucel

    Multivariable Model*: Independent Predictors for DOR of Lifileucel • Variables from the univariable analyses were examined using the best subset approach • Two parameters were identified: – Baseline LDH – Cumulative duration of prior anti–PD-1 / anti–PD-L1 Responders (N=24) Parameter Comparison HR (

  15. Slide 15: Conclusions

    Conclusions • In heavily pretreated patients with advanced or metastatic melanoma who progressed on or after multiple prior therapies, including anti–PD-1 / anti–PD-L1 and BRAF/MEK inhibitors (if BRAF V600 mutant), lifileucel treatment resulted in: – 36.4% ORR – Median DOR not reached at median 33.1
