SAN DIEGO, Nov. 09, 2021 (GLOBE NEWSWIRE) -- Turning Point Therapeutics, Inc. (NASDAQ: TPTX), a precision oncology company developing next-generation therapies that target genetic drivers of cancer, today reported financial results for the third quarter ended September 30, 2021 and provided operational updates.

“We are encouraged by the progress made across our pipeline, including recent preliminary data presented for repotrectinib and elzovantinib at the AACR-NCI-EORTC meeting,” said Athena Countouriotis, M.D., president and CEO. “We look forward to multiple anticipated upcoming FDA interactions including a pre-NDA meeting for repotrectinib in ROS1-positive non-small cell lung cancer.”

Third quarter and recent highlights include:

REPOTRECTINIB, ROS1/TRK INHIBITOR

  • Second Breakthrough Therapy Designation (BTD) granted by the U.S. Food and Drug Administration (FDA) for repotrectinib for the treatment of patients with advanced solid tumors that have an NTRK gene fusion who have progressed following treatment with one or two prior TRK tyrosine kinase inhibitors, with or without prior chemotherapy, and have no satisfactory alternative treatments. BTD is granted by the FDA to expedite the development and regulatory review of an investigational medicine that is intended to treat a serious or life-threatening condition.

    The company anticipates discussing next steps towards registration of repotrectinib in patients with NTRK-positive TKI-pretreated advanced solid tumors at a Type B meeting with the FDA in the fourth quarter of 2021.

  • Progress in the Phase 2 TRIDENT-1 registrational study of repotrectinib, where the company reported early interim data at the AACR-NCI-EORTC conference. Utilizing an August 26, 2021 data cutoff for the updated Phase 2 dataset and a July 22, 2019 data cutoff for Phase 1, the preliminary efficacy analysis across multiple cohorts pooled from the Phase 1 and Phase 2 portions of the study demonstrated confirmed objective response rates (cORRs) of 39% in ROS1-positive NSCLC patients pretreated with one prior TKI and prior platinum-based chemotherapy (EXP2: n=23); 30% in ROS1-positive NSCLC patients pretreated with two prior TKIs without prior chemotherapy (EXP-3: n=10); 38% in ROS1-positive NSCLC patients pretreated with one prior TKI without prior chemotherapy (EXP-4: n=39); 41% in NTRK-positive TKI-naïve solid tumor patients (EXP-5: n=17); and 48% in NTRK-positive TKI-pretreated solid tumor patients (EXP-6: n=23). The cORRs in patients with solvent front mutations (SFMs) were 53% in ROS1-positive TKI-pretreated NSCLC patients with a G2032R SFM (n=15), and 62% in NTRK-positive TKI-pretreated solid tumor patients with NTRK SFMs (n=13).   Phase 2 responses were determined by physician assessment, and Phase 1 responses were determined by blinded independent central review (BICR).

    The safety analysis from 301 treated patients from the pooled Phase 1 and Phase 2 portions of TRIDENT-1 across all cohorts demonstrated that repotrectinib was generally well tolerated, with the majority of treatment related adverse events reported as grade 1 or 2.
  • The company anticipates reporting topline BICR data from all of the ROS1-positive NSCLC cohorts from TRIDENT-1 and discussing the BICR data with the FDA at a pre-NDA meeting, in the second quarter of 2022. The company plans to discuss available BICR data in at least 50 TKI-naïve and 50 TKI-pretreated patients with at least six months of follow-up for the majority of responders.

  • Progress in the Phase 1/2 CARE study of repotrectinib in pediatric and young adult patients, where the company reported early data at the SIOP Congress. Utilizing an August 2, 2021 data cutoff, the company highlighted preliminary responses by physician assessment and a generally tolerable safety profile. Eight patients were evaluable for efficacy, including four TKI-naïve and four TKI-pretreated patients. Three TKI-naïve patients (two with NTRK fusion solid tumors and one with ROS1 fusion IMT) achieved confirmed responses, including 1 complete response.

ELZOVANTINIB (TPX-0022), MET/SRC/CSF1R INHIBITOR

  • Progress in the Phase 1 SHIELD-1 study of elzovantinib, Turning Point's MET, SRC and CSF1R inhibitor, where updated preliminary data from the dose finding portion of the study reported at the AACR-NCI-EORTC conference highlighted clinical activity, including objective responses across multiple tumor types and a generally tolerable safety profile utilizing an August 23, 2021 data cutoff. Among 11 MET TKI-naïve NSCLC patients, four achieved confirmed responses for a cORR of 36% across all dose levels. Among nine MET TKI-naïve gastric/gastroesophageal junction (GC/GEJ) patients, three achieved confirmed responses for a cORR of 33% across all dose levels. Elzovantinib was generally well tolerated, with the most frequently reported TEAE being dizziness (65%) of which 94% of reported cases were grade 1 or grade 2. Responses were determined by physician assessment.

  • Completion of an End of Phase 1 Meeting with the FDA focused on next steps in NSCLC, where the design of the planned Phase 2 portion of the SHIELD-1 study and the recommended Phase 2 dose (RP2D) were discussed. The company proposed a RP2D of 40 mg QD to 40 mg BID at the meeting based on available data. The FDA recommended that the company explore an additional intermediate dose level using the QD titration to BID dosing strategy in at least six to 10 patients prior to starting the Phase 2 portion of the study.

    Patient screening at the intermediate dose level (60 mg QD to 60 mg BID) is ongoing and the company plans to enroll at least six to 10 patients at this dose level and provide data from this dose level to the FDA, with the intention of revising the SHIELD-1 study into a potentially registrational Phase 1/2 study and initiating the Phase 2 portion in 2022. The company also continues to enroll patients in the Phase 1 dose expansion portion of the study at 40 mg QD to 40 mg BID.

  • FDA feedback on the development path for elzovantinib in gastric/gastroesophageal junction (GEJ) cancer is anticipated in the fourth quarter of 2021.

  • The company announced a clinical collaboration with EQRx to evaluate elzovantinib in combination with aumolertinib, EQRx’s drug candidate targeting EGFR, in patients with EGFR mutant MET-amplified advanced NSCLC. The company anticipates initiating the SHIELD-2 combination study of elzovantinib and aumolertinib in mid-2022, pending filing of an investigational new drug (IND) application by the FDA.

TPX-0046, RET INHIBITOR

  • Progress in the ongoing dose-finding portion of the Phase 1/2 SWORD-1 study, where the company continues to evaluate multiple doses and schedules to further characterize the pharmacokinetics, safety, and efficacy profile before determining the RP2D.

TPX-0131, ALK INHIBITOR

  • Ongoing patient dosing in the Phase 1/2 FORGE-1 study of TPX-0131 in locally advanced or metastatic TKI-pretreated ALK-positive NSCLC. The study endpoints include safety and tolerability, determination of the recommended Phase 2 dose, pharmacokinetics, and any early signals of efficacy.

DISCOVERY

  • Continued advancement of four internal discovery programs targeting aberrant GTPase signaling known to drive genomically defined cancers with significant unmet medical need. The most advanced programs target KRAS G12D and the p21 activated kinase, or “PAK” family. Turning Point is targeting 2 development candidates in the second half of 2022 with a goal to achieve at least one new IND per year beginning in 2023.

Third Quarter Financial Results

  • R&D Expenses: Research and development expenses were $48.9 million in the quarter, compared to $32.2 million in the third quarter of 2020. The $16.7 million increase was primarily driven by the year-over-year increase in investments to develop repotrectinib, elzovantinib, TPX-0046 and TPX-0131, discovery efforts and personnel expenses.

  • G&A Expenses: General and administrative expenses were $18.2 million compared to $11.3 million in the third quarter of 2020. This increase was primarily due to higher personnel expenses from an increase in head count and professional fees, including those associated with launch readiness.

  • Net Income/Loss: Net loss was $66.3 million compared to a net loss of $17.7 million for the third quarter of 2020. The net loss in the third quarter of 2020 was partially offset by the $25 million recorded as a result of the upfront payment from Zai Lab under the company’s license agreement for repotrectinib in Greater China.

  • Cash Position: Cash, cash equivalents and marketable securities at September 30, 2021 totaled approximately $1.0 billion, reflecting a net decrease of $86.5 million in the first three quarters of 2021. Turning Point projects its cash position funds current operations into 2024.
