Abstract

Background

NTRK gene fusions are oncogenic drivers of various solid tumour types. Entrectinib, a potent CNS-active TRK inhibitor, yielded systemic and intracranial responses in pts with NTRK-fp solid tumours in previous integrated analyses of three phase I/II trials (ALKA-372-001 [EudraCT 2012-000148-88]; STARTRK-1 [NCT02097810]; STARTRK-2 [NCT02568267]). We present updated data with ∼30% more pts and longer follow-up (data cut-off: 2 Aug 2022).

Methods

Adults with measurable, locally advanced/metastatic NTRK-fp solid tumours and ≥12 months’ follow-up from first on-study scan, who received ≥1 dose of entrectinib, were efficacy evaluable. The safety population comprised all pts who received ≥1 dose of entrectinib. Eligible pts from TAPISTRY (NCT04589845) were also included. Tumour responses were assessed by blinded independent central review per RECIST v1.1 at Week 4 and then every 8 weeks. Primary endpoints: objective response rate (ORR); duration of response (DoR). Key secondary endpoints: progression-free survival (PFS); overall survival (OS); safety.

Results

The efficacy-evaluable population comprised 194 pts with 17 types of solid tumours. Median age: 58 years (range 19–92); 63 (32.5%) pts received ≥2 prior lines of therapy. Median survival follow-up was 38.7 months. ORR was 62.4% (95% CI 55.2–69.2); the table shows responses in histologies with n>10. Median DoR was 29.4 months (95% CI 17.2–36.8). Median PFS and OS were 15.7 months (95% CI 13.7–22.9) and 38.2 months (95% CI 28.6–56.5), respectively. In the safety cohort (N=296), median treatment duration was 8.3 months (range 0.0–72.0). Of all pts with treatment-related adverse events (TRAEs; n=265), 57% had grade 1–2 TRAEs; dose reduction, interruption and discontinuation occurred in 24%, 34% and 6% of all pts, respectively.

NTRK-fp tumour types* (n>10) Objective response rate, n/N (%)
Total CNS metastases at baseline No CNS metastases at baseline 121/194 (62.4) 22/36 (61.1) 99/158 (62.7)
Non-small cell lung cancer 32/51 (62.7)
Sarcoma 23/38 (60.5)
Salivary (mammary analogue secretory carcinoma) 27/31 (87.1)
Thyroid 14/21 (66.7)
Breast 8/13 (61.5)
Colorectal cancer 4/13 (30.8)

*Other tumour types in the efficacy-evaluable cohort: neuroendocrine (n=7); head and neck (n=5); pancreatic (n=4); cancer of unknown primary (n=3); gynaecological (n=2); adrenal (n=1); cholangiocarcinoma (n=1); gastrointestinal (n=1); neuroblastoma (n=1); penile (n=1); prostate (n=1).

Conclusions

In this updated analysis, entrectinib was well tolerated and continued to induce clinically meaningful responses in pts with NTRK-fp solid tumours.
