Financial results and liquidity
| Metric | Q3 2019 | Q3 2018 | Nine months 2019 | Nine months 2018 |
|---|---|---|---|---|
| Revenue | None | None | None | None |
| Research and development expense | $13.0m | $9.2m | $37.8m | $22.3m |
| General and administrative expense | $5.0m | $3.0m | $14.6m | $7.3m |
| Net loss | $17.1m | $11.6m | $50.3m | $30.3m |
| Basic and diluted loss per share | $0.57 | $0.49 | $1.93 | $3.28 |
| Operating cash used | Not stated for quarter | Not stated for quarter | $49.1m | $26.2m |
At September 30, cash and cash equivalents were $206.4m, versus $126.3m at December 31, 2018. Current assets were $213.7m and current liabilities $9.9m. Total liabilities were $10.4m; the balance sheet does not show borrowings or debt. The company reported a $122.0m accumulated deficit. The filing gives no revenue-based margins; operating results were loss-making.
Nine-month investing cash use was $0.8m; financing provided $130.0m, principally from the July 2019 follow-on offering. Cash, cash equivalents and restricted cash increased by $80.1m to $206.9m. Management expected cash and cash equivalents to fund planned operating and capital needs into the second half of 2021, while cautioning that assumptions may prove wrong and additional capital will be needed thereafter.
Changes versus prior comparable periods
- Q3 operating expenses rose $5.8m year over year; net loss widened $5.6m. Nine-month operating expenses rose $22.8m and net loss widened $20.0m.
- Nine-month R&D growth reflected higher personnel and facilities costs, increased Pompe preclinical work, and other program spending. G&A increased with staffing and public-company costs.
- Interest income increased. The 2018 nine-month comparison included $1.6m of derivative fair-value expense and $0.2m of warrant fair-value expense, neither recurring in 2019.
- The July 2019 follow-on offering generated approximately $129.5m net proceeds from 7.475m shares. No shares had been sold under the separate $50m at-the-market facility by September 30.
Outlook, developments and risks
- Management expected substantial future spending and continuing losses as clinical programs and manufacturing capabilities advance. Profitability and product revenue were uncertain and expected to be years away, if achieved.
- AVR-RD-01 Fabry trials had dosed eight patients across Phase 1 and Phase 2 as of the reported data cutoffs. The company highlighted preliminary results, including an 87% reduction in kidney Gb3 inclusions and plasma lyso-Gb3 for one Phase 2 patient at one year, and 33%–41% lyso-Gb3 reductions in four Phase 1 patients. These small, early datasets are not proof of clinical benefit or durable efficacy.
- Reported AVR-RD-01 safety data showed no drug-product-related serious adverse events at the stated cutoffs. Serious events associated with conditioning or patient conditions had occurred; the filing said reported events had resolved. Conditioning risks, including those associated with busulfan, remain important.
- The Gaucher trial was recruiting; first enrollment was expected in Q1 2020 and dosing in Q2 2020. The first cystinosis patient was dosed in October 2019. Pompe remained in preclinical development. The company was transitioning toward its plato platform, including LV2 vector, automated manufacturing and therapeutic drug monitoring; benefits and comparability with earlier processes were not established.
- In November 2019, AVROBIO paid GenStem $2.0m after the first patient was dosed in the cystinosis trial. A further $2.0m milestone was anticipated upon first-patient dosing in a first pivotal cystinosis trial.
- Disclosure controls were deemed ineffective as of September 30, 2019 because material weaknesses remained in financial close, expense classification and accruals, and cash-disbursement controls. The filing also disclosed a 2017 cyber theft and a February 2019 fraudulent vendor invoice payment.
- Key risks include clinical and regulatory uncertainty, patient recruitment, manufacturing scale-up and third-party supplier reliance, safety and conditioning effects, competition, intellectual-property and licensing exposure, and the need for further financing. No material legal proceedings were reported.
Important facts for investors to verify
- Confirm that AVROBIO—not Tectonic Therapeutic—is the intended issuer and filing.
- Check subsequent cash burn, financing activity and whether the stated runway into the second half of 2021 remained current.
- Review updated enrollment, follow-up, efficacy and safety data for each clinical program, especially AVR-RD-01, and distinguish preliminary biomarker findings from established clinical outcomes.
- Track progress and regulatory comparability requirements for LV2, automated manufacturing and the plato platform.
- Verify remediation of the disclosed material weaknesses and any later control or cybersecurity incidents.
- Review future license milestones, including the cystinosis payments, and potential dilution from equity issuance and outstanding options.
