We continue to advance our pipeline including elzovantinib and look forward to a data-rich second half of the year, including updates from our repotrectinib and elzovantinib programs as well as a first look at our discovery program for KRAS G12D.”

 

First quarter and recent operational highlights include:

 

 


 

 

REPOTRECTINIB, ROS1/TRK INHIBITOR

Announced that the U.S. Food and Drug Administration (FDA) granted an eighth regulatory designation, and third BTD, to lead drug candidate repotrectinib. BTD was granted for the treatment of patients with ROS1-positive metastatic non-small cell lung cancer (NSCLC) who have been previously treated with one ROS1 tyrosine kinase inhibitor and who have not received prior platinum-based chemotherapy (expansion cohort EXP-4 of the TRIDENT-1 study).
Reported positive topline blinded independent central review (BICR) data from all of the ROS1-positive advanced NSCLC cohorts from TRIDENT-1, utilizing a February 11, 2022 data cutoff date. Data in both TKI-naïve and TKI-pretreated cohorts are consistent with a potentially best-in-class drug candidate for patients with ROS1-positive advanced NSCLC.

 

o
In the ROS1-positive TKI-naïve advanced NSCLC population (EXP-1: n=71), the cORR was 79% (n=56/71; 95% CI: 68, 88), with 4 patients (6%) achieving a complete response (CR) and 52 patients (73%) achieving a partial response (PR). The cORR does not include one patient in an unconfirmed partial response (uPR) with tumor regression of -38% on the last scan, who remained on treatment awaiting the next scan as of the data cutoff date.

 

DOR ranged from 1.4+ to 35.1+ months with probability of patients in a response at 6, 9, 12 and 18 months reflected in Table 1 utilizing a Kaplan-Meier analysis, with a median duration of follow-up of 10.2 months.

o
In the ROS1-positive advanced NSCLC population pretreated with one prior TKI and prior platinum-based chemotherapy (EXP-2: n=26), the cORR was 42% (95% CI: 23, 63). Duration of response ranged from 3.6 to 18.3+ months.
o
In the ROS1-positive advanced NSCLC population pretreated with two prior TKIs without prior chemotherapy (EXP-3: n=18), the cORR was 28% (95% CI: 10, 54). Duration of response ranged from 1.9+ to 20.3+ months.
o
In the ROS1-positive advanced NSCLC population pretreated with one prior TKI without prior chemotherapy (EXP-4: n=56), the cORR was 36% (95% CI: 23, 50). The cORR does not include two patients with an uPR who both had tumor regressions of -47% on their last scans, both of whom remained on treatment awaiting their next scans as of the data cutoff date. Duration of response ranged from 1.9+ to 17.8 months.
Repotrectinib was generally well tolerated in a total of 380 patients with a safety and tolerability profile that was consistent with previously reported findings.
The TRIDENT-1 study continues to enroll patients globally and enrollment across all six cohorts of the study remains open and continues to progress steadily.

 

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

Phase 1 dose escalation completed utilizing intermediate dose level of 60 mg QD to 60 mg BID.
Patient enrollment continues in the SHIELD-1 study at 40 mg QD to 40 mg BID in Phase 1 dose expansion.

 

TPX-0046, RET INHIBITOR

Ongoing characterization of the pharmacokinetics, safety, and efficacy profile in the dose finding portion of the study before determining the recommended Phase 2 dose (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.

 

TPX-4589, CLAUDIN18.2 ADC

Announced exclusive license agreement with LaNova Medicines to develop and commercialize TPX-4589 (LM-302), a novel, potentially first-in-class, antibody drug conjugate (ADC) targeting Claudin18.2 in the US and rest of the world excluding Greater China and South Korea. Claudin18.2 is a protein expressed in many gastrointestinal cancers, including gastric, gastroesophageal, and pancreatic cancer. TPX-4589 (known in China as LM-302) is currently in Phase 1 clinical trials in both the U.S. and China.

 


 

 

Received two Orphan Drug Designations (ODDs) from the FDA in the first quarter of 2022. ODDs were granted to LaNova Medicines for the treatment of pancreatic cancer and for the treatment of gastric cancer, including cancer of the gastroesophageal junction.

 

DISCOVERY

Continued advancement of 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. The company is targeting nomination of two development candidates in the second half of 2022 with a goal to achieve at least one new IND per year beginning in 2023.
