SAN DIEGO, May 10, 2022 – Turning Point Therapeutics, Inc. (NASDAQ: TPTX), a clinical-stage precision oncology company designing and developing novel targeted therapies for cancer treatment, today reported financial results for the quarter ended March 31, 2022 and provided operational updates.

“We are pleased with our continued progress led by our topline data for repotrectinib and now our third BTD being granted for our lead asset,” said Athena Countouriotis, M.D., President and CEO. “We recently expanded our clinical pipeline with our first in-license of TPX-4589, our potential first-in-class ADC targeting Claudin18.2, which was recently granted orphan drug designation by the FDA for both gastric and pancreatic cancers. 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.

oIn 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.

Table 1.
	TKI-Naïve (EXP-1) Responder Population (n=56 (Phase 1 n=7, Phase 2 n=49))
Efficacy Parameter	Patients at Risk	DOR Landmark
% DOR ≥ 6 months 95% CI	35	91% (82, 100)
% DOR ≥ 9 months 95% CI	29	88% (78, 98)
% DOR ≥ 12 months 95% CI	21	85% (73, 96)
% DOR ≥ 18 months 95% CI	8	76% (61, 91)

Patients at Risk: Patients who have reached the specified timepoint without censoring or an event (progression or death).

▪PFS ranged from 0+ to 40.4+ months with probability of patients remaining progression free at 6, 9, 12 and 18 months reflected in Table 2 utilizing a Kaplan-Meier analysis, with a median duration of follow-up of 10.8 months.

Table 2.
	TKI-Naïve (EXP-1) Overall Population (n=71 (Phase 1 n=8, Phase 2 n=63))
Efficacy Parameter	Patients at Risk	PFS Landmark
% PFS ≥ 6 months 95% CI	46	91% (84, 98)
% PFS ≥ 9 months 95% CI	37	85% (75, 94)
% PFS ≥ 12 months 95% CI	26	82% (72, 93)
% PFS ≥ 18 months 95% CI	11	72% (58, 86)

Patients at Risk: Patients who have reached the specified timepoint without censoring or an event (progression or death).

oIn 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.

oIn 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.

oIn 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.

Repotrectinib Combinations in KRAS-Driven Tumors

Inhibits JAK2, SRC and FAK Leads to suppression of STAT3 and AKT signaling, major mechanisms of resistance Demonstrated synergy with trametinib (MEK inhibitor) in mutant KRAS NSCLC, CRC and pancreatic cancer cell lines Demonstrated synergy with AMG510, inhibiting KRASG12C tumor cell proliferation, suppressing receptor tyrosine kinase upregulation, reducing KRASG12C tumor cell cytokine release Repotrectinib Selectivity Profile Potentially Expands Opportunity Beyond ROS1 and TRK for Combinations Note: Data presented at 2020 and 2021 annual AACR meetings. Authors: B. Murray, et al. REPOTRECTINIB IN PRECLINICAL MODELS Inhibited by Repotrectinib

Repotrectinib combination with trametinib is more effective than single-agent treatment in patient-derived KRAS mutant lung (KRAS G12D/V) and pancreatic (KRAS G12D/V/R) spheroid models Repotrectinib enhances trametinib efficacy in mutant KRAS G12D in vivo lung tumor models Overall, preclinical combination data suggest that a combination with repotrectinib may enhance trametinib potency and may improve durability of response by reversing or preventing acquired resistance Repotrectinib / Trametinib Combination Exhibits Greater Tumor Growth Inhibition in KRAS G12D Syngeneic and PDX Lung Cancer Models Note: Data presented at 2021 annual AACR meeting. mLU6045 KRAS G12D 1500 1000 500 0 Tumor Volume mm3 (SEM) 0 5 10 15 20 25 Days of Treatment Vehicle BID Repotrectinib 15 mg/kg BID Trametinib 1 mg/kg QD Repotrectinib 15 mg/kg BID + Trametinib 1 mg/kg QD **** ~2-fold increase in TGI **** p < 0.0001
