by year-end 2026 and 2027 outlook
- NoteTopline data from the Phase 2 PIK-201 trial in endometrial cancer expected by year-end
- NotePIKTOR is being evaluated in a Phase 2 trial in second-line advanced endometrial cancer (Study FTH-PIK-201), with topline data anticipated by year-end 2026.
- NotePIKTOR is also being evaluated in a Phase 1b/2 trial in HR+/HER2- advanced breast cancer (Study FTH-PIK-101), in which the first patient was dosed in April 2026 and interim data is anticipated in 2027.
What drove it
- The increase in R&D expenses was primarily driven by development costs for PIKTOR and other Faeth programs, including clinical trial, chemistry, manufacturing and controls (CMC) and preclinical expenses, together with higher personnel costs, partially offset by lower clinical trial costs for legacy Sensei programs.
- The increase in G&A expenses was primarily attributable to higher personnel costs and increased external administrative fees, primarily legal fees.
- FDA granted Fast Track designation to PIKTOR in combination with paclitaxel for the treatment of patients with advanced or recurrent endometrial cancer whose tumors harbor a PI3K/AKT/mTOR (PAM) pathway alteration and who have previously been treated with platinum-based chemotherapy and an immune checkpoint inhibitor.
- The Company selected 3 mg sapanisertib and 200 mg serabelisib three days a week as the recommended Phase 2 dose for PIKTOR in the PIK-201 trial.
Concerns
- Net loss was $20.4 million for the quarter ended September 30, 2026, compared with a net loss of $4.6 million for the quarter ended September 30, 2025.
- The filing identifies risks related to clinical development and the conduct, timing and results of clinical trials.
- The filing identifies risks related to reliance on third parties for the supply of investigational agents used in combination studies.
- The filing identifies risks related to the Company’s cash position and anticipated cash runway, its need for additional financing, limited operating history and history of operating losses.
What to watch
- Topline data from the Phase 2 PIK-201 trial in endometrial cancer anticipated by year-end 2026.
- Initial safety and efficacy data from the PIK-101 trial in HR+/HER2- breast cancer anticipated in 2027.
- The clinical implications of the FDA Fast Track designation for PIKTOR plus paclitaxel in biomarker-selected advanced endometrial cancer.
- Continued R&D and G&A expense levels as the Company develops PIKTOR and other Faeth programs.
Balance sheet and cash flow
- Cash, cash equivalents and marketable securities were $174.8 million as of September 30, 2026, as compared to $21.2 million as of December 31, 2025.

Analysis
Faeth reported a clinical-stage operating profile for the third quarter of 2026, with no revenue reported in the filing and spending concentrated on development activity. Research and development expenses were $11.7 million, compared with $2.5 million in the prior-year quarter. The company attributed the increase to PIKTOR and other program development costs, including clinical trial, CMC and preclinical spending, as well as higher personnel costs, partly offset by lower legacy Sensei clinical trial costs.
General and administrative expenses were $10.4 million, compared with $2.3 million in the prior-year quarter, driven by higher personnel costs and external administrative fees, primarily legal fees. Total operating expenses were $ 22,086 and loss from operations was $(22,086). Total other income was $ 1,688, resulting in net loss of $20.4 million, or $0.79 per basic and diluted share, versus net loss of $4.6 million, or $3.62 per basic and diluted share, in the prior-year period. Weighted-average common shares outstanding were 25,840,555, compared with 1,261,290.
Liquidity increased from year-end. Cash, cash equivalents and marketable securities were $174.8 million as of September 30, 2026, compared with $21.2 million as of December 31, 2025. The balance sheet reported cash and cash equivalents of $ 14,180 and marketable securities of 160,615. The release did not provide operating cash flow, free cash flow, debt, a quantified cash runway or capital-return activity.
Operationally, the central near-term catalyst is topline data from the Phase 2 PIK-201 endometrial cancer trial anticipated by year-end 2026. The FDA granted Fast Track designation to PIKTOR plus paclitaxel for biomarker-selected advanced or recurrent endometrial cancer after specified prior treatment. Faeth also selected 3 mg sapanisertib and 200 mg serabelisib three days a week as the recommended Phase 2 dose for PIKTOR in PIK-201, following PK/PD analysis.
The company also expects interim data from the PIK-101 Phase 1b/2 study in HR+/HER2- advanced breast cancer in 2027. The filing highlights preclinical ESMO data in which PIKTOR was tested as monotherapy and in combination with SERDs and CDK inhibitors. The investment focus remains clinical execution and data timing, alongside the pace of development and administrative spending against the reported liquidity position.
Management, verbatim
Since our last quarterly update, we presented PK/PD analysis that informed the PIKTOR dose in our Phase 2 PIK-201 trial and received Fast Track designation for PIKTOR plus paclitaxel in biomarker-selected advanced endometrial cancer.
Anand Parikh, Chief Executive Officer
The PAM pathway is dysregulated in up to 50% of solid tumors, and feedback reactivation and resistance mutations may limit single-node inhibitors. We designed PIKTOR, an all-oral, multi-node inhibitor, to address those limitations, and we believe it has the potential to give patients a differentiated treatment option.
Anand Parikh, Chief Executive Officer
We look forward to reading out topline data from our Phase 2 PIK-201 trial in endometrial cancer by year-end, and to reporting initial safety and efficacy data from our PIK-101 trial in HR+/HER2- breast cancer in 2027.

Background
Faeth Therapeutics is a clinical‑stage oncology company developing the multi‑node inhibitor PIKTOR for endometrial and breast cancers.
Ticker impact
Faeth Therapeutics filed its Q3 2026 8‑K reporting a $20.4 M net loss and $174.8 M cash balance, plus FDA Fast Track for PIKTOR.
downward pressure as investors digest larger loss and increased expenses
The disclosed net loss widened dramatically year‑over‑year and R&D spend more than quadrupled, suggesting short‑term earnings disappointment.
Market effects
Highlights continued investment in multi‑node PI3K/AKT/mTOR oncology therapies, may spur peer scrutiny.
Limited to US biotech sector; no broader regional effect.
Modest, confined to specialty biotech investors.
Counterpoint
Cash runway of $174 M could support future milestones, offering upside if Phase 2 data are positive.
