NGR-hTNF (asn-gly-arg-human tumor necrosis factor) is a selective vascular targeting agent able to improve intratumoral chemotherapy uptake.


After stratification by histology (nonsquamous or squamous) and PS (0 or 1), previously untreated patients (pts) with advanced NSCLC were randomly assigned to receive cisplatin 80 mg/m2/d1 plus either pemetrexed 500 mg/m2/d1 (nonsquamous) or gemcitabine 1,250 mg/m2/d1 + 8 (squamous) q3w for 6 cycles with (arm A) or without (arm B) NGR-hTNF 0.8 µg/m2/d1 q3w given until progression. Progression-free survival (PFS) was primary endpoint of this phase 2 trial (� = 20%, α = 20%, n = 102). Secondary endpoints included adverse events (AEs), overall survival (OS), and response rate (RR).


Baseline characteristics in arm A (n = 61) v B (n = 58): median age 62 v 63 years; male 36 v 38; PS of 1 22 v 22; squamous 17 v 16; nonsmokers 19 v 14; EGFR mutations 5 v 5. For the nonsquamous stratum, 295 cycles were given in A (mean 6.9; range 1-18) and 192 in B (4.8; 1-6), while for the squamous stratum, 95 in A (6.3; 1-24) and 49 in B (3.5; 1-6). The rates of grade 3 to 4 AEs were comparable in arm A v B: neutropenia 14% v 17% and fatigue 7% v 11%. Neither grade 3 to 4 AEs related to NGR-hTNF nor bleeding in pts with squamous histology were noted. With a median follow-up of 16.4 months for all pts, median PFS was 5.8 v 5.6 months, 1-year OS rate was 58% v 56%, and RR was 25% v 21% in arm A v B, respectively. For the nonsquamous stratum, trends toward higher 6-month PFS rates for arm A v B were noted in pts with PS 1 (65% v 33%), nonsmoking history (59% v 33%), younger age (64% v 30%), and EGFR mutations (75% v 25%). Similarly, in these pts the 1-year OS rates were: PS 1 (60% v 56%), nonsmoking history (77% v 65%), younger age (75% v 63%), and EGFR mutations (100% v 50%). For the squamous stratum, median PFS was 5.6 v 4.3 months (HR = 0.71) and median OS was 14.2 v 10.2 months (HR = 0.54) for arm A v B, respectively. In these pts, RR was 36% for arm A and 23% for arm B, while median changes from baseline in target tumor size after 2, 4, and 6 cycles were -27%, -39%, and -33%, respectively for arm A, and -18%, -22%, and -14%, respectively for arm B.


NGR-hTNF can be safely given with standard chemotherapy and may have therapeutic potential in squamous NSCLC
