Abstract 919MO


Notch signaling plays a key role in ACC tumorigenesis. AL101, an investigational γ-secretase inhibitor, blocks Notch signaling and inhibits tumor in ACC patient-derived xenograft models with Notchmut (AACR ‘19, Abstr 4885). Notchmut are found in ∼20% of ACC tumors these tumors are aggressive with a poor prognosis (Ferrarotto 2016, Ho 2019). No therapies are approved for R/M ACC. Updated results (n = 45) will be provided.


ACCURACY is an open-label, multicenter study of AL101 (4 and 6 mg IV QW) in R/M ACC subjects (bone-only disease allowed) with known Notch1-4mut (ASCO ‘19, Abstr TPS6098). Subjects require evidence of disease progression within 6 months of entry or newly diagnosed metastatic disease and an ECOG PS of <2. Primary endpoint: ORR by RECIST v1.1 (or modified MD Anderson bone criteria), by investigator. Secondary endpoints: ORR by central review, duration of response and safety. The study was amended, based on the safety and activity in the 4 mg cohort, to add a cohort of 42 subjects at 6mg. The study will provide at least 80% power to detect an increase of the response rate from 8% to 25% using a type I error of 5%.


45 subjects were enrolled at 4 mg QW; 39 are evaluable for efficacy. Table: 919MO

Disposition and baseline characteristics of subjects treated with the investigational new drug AL101-4 mg

Treated, n Evaluable, n Median number of cycles, n 45 39 5
Gender, n, (%) Male Female 20 (44%) 25 (56%)
Median age, years 50 (range)
Race, n, (%) White Black Asian Other Not Reported 30 (68%) 4 (9%) 2 (4%) 2 (4%) 7 (16%)
ECOG performance status, n, (%) 0 1 21 (47%) 24 (53%)
Prior Systemic Therapy, n, (%) 45 (71%)
Disease status, n, (%) With nodal or visceral metastases With bone-exclusive metastases 42 (93%) 3 (7%)
The most common (≥15%) treatment-related AEs (all Grades) included diarrhea (51%), nausea (49%), fatigue (47%), and vomiting (24%) with 24% Grade 3/4. Grade 3 events included diarrhea (4%), nausea (2%), fatigue (2%), and hypophosphatemia (9%). There were no Grade 4 or treatment-related deaths. In the 4mg group there were 6 partial responses and 21 stable disease out of 39 evaluable subjects. Most PRs were achieved by week 16, 13/39 of subjects were on study for at least 24 weeks or are still on drug not having reached 24 weeks.


Investigational AL101 has clinical activity in R/M Notch mutant ACC and appears to be well tolerated. The trial was amended to enroll additional subjects at 6 mg QW.
