15 total trials none currently recruiting 13 completed early-phase tilt top decile by trial count

ImmunoGen: 15 sponsored US clinical trials, none currently recruiting.

ImmunoGen sponsors 15 registered US clinical trials on ClinicalTrials.gov, none currently recruiting, and 13 completed. 2 of these trials are in Phase 3-4 (later-stage) and 13 in Phase 1-2 (earlier-stage). The most-studied condition in this pipeline is Non-colorectal Cancer, with 1 trials.

Top-decile sponsor footprint

ImmunoGen ranks in the top decile of sponsors by registered trial count (#934 of 15,742 sponsors by registered trial count). Volume at this scale usually reflects a long institutional pipeline, read phase tilt and therapeutic areas below before treating it as current-year activity.

Trial completion reliability score

D 56/100

13 of 15 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (86.7%), vs. national p10 68.4% / p90 100% among 1,234 sponsors with at least 10 decided trials. Still-open trials (Recruiting, Active-not-recruiting, Not-yet-recruiting) are excluded since they have not reached an outcome yet.

How the ImmunoGen early-phase archive is shaped

15 indexed studies, none listed as recruiting (0% open); 13 completed (87%).

Phase mix: 2 late (III/IV) vs 13 early (I/II) (early-phase heavy).

Top condition: Non-colorectal Cancer (1 trial), 7 others listed.

How to read a closed sponsor archive

When recruiting_count is zero, the indexed set is completed or otherwise not open. Phase tilt still describes where archived studies sat on the investigational pathway. Re-check ClinicalTrials.gov before acting.
