In this phase 2 multicenter study, we evaluated the efficacy and safety of lifileucel (LN-145), an autologous tumor-infiltrating lymphocyte cell therapy, in patients with metastatic non-small cell lung cancer (mNSCLC) who had received prior immunotherapy and progressed on their most recent therapy. Two patients died of treatment-emergent adverse events: cardiac failure and multiple organ failure. Lifileucel is a potential treatment option for patients with mNSCLC refractory to prior therapy.

Based on the encouraging efficacy, tolerable safety profile, and advancements in a central manufacturing process, lifileucel is now the first US Food and Drug Administration (FDA)-approved TIL cell therapy product...These recommendations provide practical guidelines for optimal clinical management during administration of the TIL cell therapy regimen, and recognition of subsequent management of toxicities. These guidelines are focused on multidisciplinary teams of physicians, nurses, and stakeholders involved in the care of these patients.

Lifileucel, an FDA-approved tumor-infiltrating lymphocyte therapy, has demonstrated improved response rates in advanced-stage melanoma...While immunotherapy has significantly advanced melanoma treatment, its success varies, prompting research into new drugs and factors influencing outcomes. This review provides insights into current melanoma treatments and recent therapeutic advances.

Of 153 pts who received lifileucel, 109 (71%) were primary resistant (SITC definition) and 83 (54%) were primary refractory (study definition). In primary resistant pts, ORR with lifileucel was 33% (95% CI: 24%, 43%) and median DOR was not reached (NR; 95% CI: 12.5 mo, NR). In primary refractory pts, ORR was 31% (95% CI: 22%, 42%) and median DOR was NR (95% CI: 15.1 mo, NR).

Background Aldesleukin (IL-2), at high doses in repeat cycles, is approved as monotherapy for patients (pts) with metastatic melanoma...Methods Pts with advanced melanoma received cyclophosphamide and fludarabine (NMA-LD, Day –7 to –1), a single lifileucel infusion (Day 0), and ≤6 IL-2 doses (600,000 IU/kg) every 8–12 h (Day 0–4)...Pts with disease refractory to prior IL-2 monotherapy derived benefit from lifileucel. Presence of G3/4 lymphopenia in all pts at time of IL-2 administration argues against a direct antineoplastic effect of abbreviated IL-2 dosing as part of the lifileucel regimen.

Available cases from C1A (ICI-naïve pts receiving lifileucel + pembrolizumab [pembro]) were matched to controls from C2 (pts receiving lifileucel alone after progression on anti?PD-1/PD-L1 therapy); 3 controls per case were matched at least for BRAF status and disease stage at study entry, and if possible, for anatomic site of tumor harvest. Our preliminary data indicate that the efficacy (ORR) of lifileucel may be independent of TMB, regardless of treatment setting, consistent with its proposed immune checkpoint pathway-independent mechanism of action. The percentage of patients with high TMB tended to be lower in tumors with prior ICI exposure than in those that were ICI-naïve.

Background: Lifileucel TIL cell therapy has demonstrated safety and activity in treating patients with advanced melanoma Sarnaik AA, et al... Time to ship fresh tumors from Australia ≥3 days was substantially longer than our experience with tumors shipped within the US <1–2 days, data on file, and logistical challenges may limit the utility of this treatment using fresh tumors . Tumors that were frozen locally in Australia prior to shipment consistently produced sufficient dose for TIL treatment 4/4 samples; TIL manufacturing using fresh tumors was less reliable 3/4 samples. Additional tumor samples will be analyzed to continue optimizing the TIL manufacturing process using samples from Australia.

Therapy consisted of nonmyeloablative lymphodepletion (cyclophosphamide / fludarabine), a single lifileucel infusion, followed by up to 6 doses of IL-2. post-therapy. Median DOR was still not reached at median follow-up of 28 month of study follow up, and 11 patients (17%) had further SOD reduction since previous data cut of Apr2020. Iovance is investigating lifileucel in earlier disease settings, in combination with ICI, and in other metastatic solid malignancies.

Lifileucel treatment results in a 36.4% ORR and mDOR was not reached at 17.0 months of median study follow up in a heavily pretreated metastatic melanoma patients with high baseline disease burden who progressed on multiple prior therapies, including anti-PD1 and BRAF/MEK inhibitors, if BRAFv600 mutant.
