FOR IMMEDIATE RELEASE
NewLink Genetics Presents Encouraging Phase 2 Results for NLG207 in Ovarian Cancer at AACR 2019
AMES, Iowa, April 2, 2019 - NewLink Genetics Corporation (NASDAQ:NLNK) today announced results from a Phase 2 study of NLG207, a nanoparticle formulation of the topoisomerase 1 inhibitor camptothecin, conducted in conjunction with The GOG Foundation, Inc. (GOG-3008), in patients with refractory ovarian cancer. The data were presented in a poster session at the American Association for Cancer Research (AACR) Annual Meeting 2019 in Atlanta, Georgia.
"We are encouraged by the responses observed in this Phase 2 trial of NLG207 in combination with weekly paclitaxel for patients with recurrent ovarian, fallopian tube or primary peritoneal cancer, with good results seen in the cohort of platinum resistant and refractory patients,” said Linda R. Duska, MD, Professor of Obstetrics and Gynecology at the University of Virginia School of Medicine. “Equally encouraging is how well tolerated this regimen was in women who have already had multiple lines of therapy. The results from this trial demonstrate the potential for NLG207 as a component of a treatment regimen for women with recurrent ovarian cancer, especially for those resistant to platinum therapy, an area of unmet need.”
NLG207 (formerly CRLX101), a nanoparticle-drug conjugate (NDC) composed of a cyclodextrin-based polymer backbone linked to camptothecin, a topoisomerase 1 inhibitor, was previously observed to have single agent activity in both preclinical1 and clinical studies.2 A previous Phase 2 trial evaluating NLG207 administered as monotherapy enrolled 29 patients with ovarian, fallopian tube, or primary peritoneal cancer, 22 of which were classified as platinum resistant. Of these 22 patients, 19 were evaluable for efficacy with follow-ups using computerized tomography (CT) scans performed every two cycles. Of these 19 evaluable patients, 17 (74%) demonstrated a net tumor reduction and three (16%) achieved durable partial responses per RECIST.2
In the study reported on today, NLG207 was administered in combination with paclitaxel to patients with recurrent ovarian, fallopian tube, or peritoneal cancer in a Phase 1b/2, single-arm, open label expansion study. Thirty patients were enrolled, and all received at least one cycle of treatment: 3 patients received the lower lead-in Phase 1b dosing schedule of 12 mg/m2 i.v. (every two weeks) plus weekly paclitaxel 80 mg/m2 i.v. (three weeks on, one week off) and 27 patients received the recommended Phase II dose NLG207 15 mg/m2 i.v. (every two weeks) plus weekly paclitaxel 80 mg/m2 i.v. (three weeks on, one week off). The primary objective of the study was overall response rate (ORR = complete response [CR] + partial response [PR]) per RECIST 1.1. Secondary objectives included evaluation of progression-free survival (PFS), PFS at 6 months (PFS6), and duration of response (DOR) in patients with recurrent platinum resistant cancer, and safety.
N = 30 patients, with all completing at least one cycle (27/30 at Phase 2 dosing schedule; 3/30 at lower lead-in Phase 1b dosing schedule)
57% received ≥ 3 prior therapies
ORR 26.7% (8/30) confirmed, including one CR
Median DOR was 6.0 months
Median PFS was 5.4 months
Patients with platinum resistant cancer: N = 17
ORR 23.5% (4/17) confirmed
Best response (including unconfirmed) 41.2% (7/17), all PRs
Stable disease (SD) 29.4% (5/17)
Patients with platinum sensitive cancer: N = 13
ORR 30.8% (4/13) confirmed and best response
Most common treatment related grade 3 / 4 adverse events: decreased neutrophil count 43% (13/30), anemia 10% (3/30), hematuria 7% (2/30)
NLG207 is a potentially best-in-class topoisomerase 1 inhibitor with demonstrated antitumor activity in recurrent ovarian cancer, including cancer resistant to platinum therapy. The combination therapy of NLG207 plus weekly paclitaxel was well tolerated in heavily pretreated patients with most adverse events consistent with those observed for paclitaxel as a single agent. Prior single agent activity observed in both preclinical and clinical studies, along with Phase 2 results in combination with paclitaxel reported here, support further investigation of NLG207 as a single agent and in combination treatment regimens for patients with recurrent ovarian, fallopian tube or primary peritoneal cancers, particularly those which are platinum resistant.
“We were excited by the single agent activity of NLG207 observed in prior trials and are encouraged by the Phase 2 data presented today at AACR that support the potential for this drug candidate to improve upon current therapies in ovarian cancer, particularly given its favorable safety profile,” said Charles J. Link, Jr, MD, Chairman and Chief Executive Officer of NewLink Genetics. “We wish to thank the patients, their families, and the investigators who participated in this trial as we continue our efforts to better the lives of individuals suffering from cancer.”
Abstract CT151 (Poster 17) entitled, A phase II study of NLG207 (formerly CRLX101) in combination with weekly paclitaxel in patients with recurrent or persistent epithelial ovarian, fallopian tube or primary peritoneal cancer, Duska, L., et al, was presented during the poster session entitled, “Phase II-III Clinical Trials: Part 1,” in Exhibit Hall B, Poster Section 16 from 8:00 a.m. - 12:00 p.m. ET.

NLG207 (formerly CRLX101) is an investigational nanoparticle-drug conjugate (NDC) composed of a cyclodextrin-based polymer backbone conjugated to camptothecin, a topoisomerase 1 inhibitor. NDCs enhance drug delivery to tumors where gradual payload release inside cancer cells augments antitumor activity while reducing toxicity. Topoisomerase 1 inhibitors are a class of drugs that modify DNA damage responses in cancer cells. NewLink Genetics is evaluating NLG207 in a series of clinical trials in advanced refractory ovarian cancer patients.
