BOSTON--(
BUSINESS WIRE
)--Tango Therapeutics, Inc. (NASDAQ: TNGX), a clinical-stage biotechnology company committed to discovering and delivering the next generation of precision cancer medicines, reported its financial results for the third quarter ended September 30, 2024, and provided business highlights.
“
We have made great progress with our PRMT5 development program, including positive data from the TNG462 phase 1/2 clinical trial that showcase the best-in-class potential of TNG462 in multiple tumor types, including pancreatic and non-small cell lung cancers (NSCLC). Based on these early data, we are advancing TNG462 into trials with multiple targeted and standard of care combinations, including two RAS(ON) tri-complex inhibitors from Revolution Medicines. Given that nearly all MTAP-deleted pancreatic cancer has a co-occurring RAS mutation, we believe this could be a powerful approach to changing the treatment landscape for this challenging cancer,” said Barbara Weber, M.D., President and Chief Executive Officer of Tango Therapeutics. “
As part of the expanded capabilities needed to rapidly move TNG462 development forward, Dr. Maeve Waldron-Lynch, M.D. is joining Tango as Senior Vice President, Head of Clinical Development. Dr. Waldron-Lynch has extensive late-stage oncology clinical development and regulatory experience and will be invaluable as we prepare to advance TNG462 to registration.”
In a separate
press release
issued earlier today, Tango Therapeutics provided an update on its ongoing PRMT5 clinical development program:
Data from the ongoing phase 1/2 clinical trial of TNG462, a potentially best-in-class MTA-cooperative PRMT5 inhibitor, demonstrate clinical activity across multiple tumor types, including NSCLC and pancreatic cancer. Of note, this includes an ORR of 43% in cholangiocarcinoma (n=7). Substantive durability and a good safety and tolerability profile also were observed in this ongoing trial. The next clinical update is expected in 2025.
The Company plans to initiate multiple targeted and standard of care combinations with TNG462 including RAS(ON) multi-selective and RAS(ON) G12D-selective inhibitors (Revolution Medicines), osimertinib (AstraZeneca) and pembrolizumab (Merck). These studies are expected to begin enrolling in 1H 2025.
TNG908, an MTA-cooperative brain-penetrant PRMT5 inhibitor, is clinically active and well-tolerated across non-CNS cancers in the phase 1/2 clinical trial. In particular, there were a total of nine evaluable pancreatic cancer patients, two with partial responses (ORR 22%) and five with stable disease as best response to date. The five ongoing pancreatic cancer patients have been on study for an average of 24 weeks, the longest for 72 weeks.
TNG908 did not demonstrate activity in glioblastoma (n=23 at active doses) likely because CNS exposure did not meet the required exposure threshold for clinical efficacy.
TNG908 enrollment is being stopped to allow full resourcing of TNG462 as a potential best-in-class molecule. In particular, the notably longer time on treatment observed – 24 weeks and still increasing for TNG462 versus 16 weeks for TNG908 – the superior target coverage, and the safety and tolerability profile all support selection of TNG462 for further development.
TNG456 is a next-generation brain-penetrant MTA-cooperative PRMT5 inhibitor that is 55X selective for MTAP deletion with 20 nM potency. Preclinical studies suggest TNG456 central nervous system exposure has the potential to be sufficient for meaningful efficacy in glioblastoma and brain metastases.
The Company expects to begin enrolling patients in the planned phase 1/2 trial during 1H 2025.
Business Highlights
Clinical collaboration with Revolution Medicines
In November 2024, the Company entered into a clinical collaboration with Revolution Medicines to evaluate the efficacy and safety of TNG462 in combination with RMC-6236, a RAS(ON) multi-selective inhibitor, and with RMC-9805, a RAS(ON) G12D-selective inhibitor.
The agreement provides that Revolution Medicines will supply RMC-6236 and RMC-9805 to Tango and that Tango will be the sponsor of any combination trials. Each company will retain commercial rights to their respective compounds and the agreement is mutually non-exclusive.
TNG260, a first-in-class, highly selective CoREST complex inhibitor
The TNG260 phase 1/2 clinical trial is ongoing, evaluating safety, pharmacokinetics, pharmacodynamics and efficacy of TNG260 in combination with pembrolizumab in patients with locally advanced or metastatic solid tumors with an STK11 loss-of-function mutation. To date, safety, tolerability and pharmacokinetic profiles are favorable.
STK11 mutations occur in approximately 15% of non-small cell lung, 15% of cervical, 10% of carcinoma of unknown primary, 5% of breast and 3% of pancreatic cancers.
Upcoming Milestones
TNG462 clinical data update expected in 2025
TNG462 combination trial enrollment expected to begin 1H 2025
TNG456 phase 1/2 trial enrollment expected to begin 1H 2025
TNG260 clinical data expected in 2025

Financial Results
As of September 30, 2024, the Company held $293.3 million in cash, cash equivalents and marketable securities, which the Company expects to be sufficient to fund operations into the third quarter of 2026, including for additional planned TNG462 and TNG456 clinical trials.
Collaboration revenue was $11.6 million for the three months ended September 30, 2024, compared to $10.7 million for the same period in 2023, and $25.9 million for the nine months ended September 30, 2024 compared to $26.1 million for the same period in 2023. Collaboration revenue increased due to changes to estimated costs expected to be incurred under the collaboration during the three months ended September 30, 2024.
License revenue was $0 and $12.1 million for the three and nine months ended September 30, 2024, respectively, compared to $0 and $5.0 million for the three and nine months ended September 30, 2023, respectively. The year-to-date increase is primarily due to licensing a drug discovery program to Gilead for $12.0 million during the second quarter of 2024 as compared to Gilead licensing a program for $5.0 million during the second quarter of 2023.
Research and development expenses were $33.3 million for the three months ended September 30, 2024, compared to $27.1 million for the same period in 2023, and $110.0 million for the nine months ended September 30, 2024 compared to $83.9 million for the same period in 2023. The change is due to increased spend related to the advancement of TNG462, preclinical programs and personnel-related costs to support our research and development activities.
General and administrative expenses were $11.2 million for the three months ended September 30, 2024, compared to $9.2 million for the same period in 2023, and $32.7 million for the nine months ended September 30, 2024 compared to $26.4 million for the same period in 2023. The change was primarily due to increases in personnel-related costs.
Net loss for the three months ended September 30, 2024 was $29.2 million, or $0.27 per share, compared to a net loss of $22.3 million, or $0.23 per share, in the same period in 2023. Net loss for the nine months ended September 30, 2024 was $92.6 million, or $0.85 per share, compared to a net loss of $71.0 million, or $0.78 per share, in the same period in 2023.

Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Tango and its management, are inherently uncertain. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: the benefits of product candidates seen in preclinical tests and analyses may not be evident when tested in later preclinical studies or in clinical trials or when used in broader patient populations (if approved for commercial sale); Tango has limited experience conducting clinical trials (and will rely on a third party to operate its clinical trials) and may not be able to commence its clinical trials (including opening clinical trial sites, dosing the first patient, and continued enrollment and dosing of an adequate number of clinical trial participants) when expected, may not be able to continue dosing, initiate dose escalation and/or dose expansion on anticipated timelines, and may not generate or report clinical trial results (including final, initial or additional safety, efficacy data and proof-of-mechanism and proof-of-concept) in the anticipated timeframe (or at all); future clinical trial data releases may differ materially from initial or interim data from our current and future clinical trials; Tango’s pipeline products may not be safe and/or effective in humans; Tango has a limited operating history and has not generated any revenue to date from product sales, and may never become profitable; other companies may be able to identify and develop product candidates more quickly than the Company and commercially introduce the product prior to the Company; the Company’s proprietary discovery platform is novel and may not identify any synthetic lethal targets for future development; the Company may not be able to identify development candidates on the schedule it anticipates due to technical, financial or other reasons; the Company may not be able to file INDs for development candidates on time, or at all, due to technical or financial reasons or otherwise; the Company may utilize cash resources more quickly than anticipated; Tango will need to raise capital in the future and if we are unable to raise capital when needed or on attractive terms, we would be forced to delay, scale back or discontinue some of our development programs or future commercialization efforts (which may delay filing of INDs, dosing patients, initiation of dose expansion, reporting clinical trial results and filing new drug applications); Tango’s approach to the discovery and development of product candidates is novel and unproven, which makes it difficult to predict the time, cost of development, and likelihood of successfully developing any products; the Company may be unable to advance our preclinical development programs into and through the clinic for safety or efficacy reasons or commercialize our product candidates or we may experience significant delays in doing so as a result of factors beyond Tango’s control; the Company may not be able to realize the benefits of orphan drug or Fast Track designation (and such designations may not advance any anticipated approval timelines); the expected benefits of our product candidates in patients as single agents and/or in combination may not be realized; the Company may experience delays or difficulties in the initiation, enrollment, or dosing of patients in clinical trials or the announcement of clinical trial results, Tango may not identify or discover additional product candidates or may expend limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success; the Company’s product candidates may cause adverse or other undesirable side effects (or may not show requisite efficacy) that could, among other things, delay or prevent regulatory approval; our dependence on one or a limited number third parties for conducting clinical trials and producing drug substance and drug product (including drug substance, which is currently sole sourced); government regulation may negatively impact the Company’s business, including the potential approval of the BIOSECURE Act; and our ability to obtain and maintain patent and other intellectual property protection for our technology and product candidates or the scope of intellectual property protection obtained is not sufficiently broad. Additional information concerning risks, uncertainties and assumptions can be found in Tango’s filings with the Securities and Exchange Commission (SEC), including the risk factors referenced in Tango’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as supplemented and/or modified by its most recent Quarterly Report on Form 10-Q.
