Earnings call summaries
Pick a quarter — each call distilled into takeaways, results, and a bull vs bear read.
Aileron said ALRN-6924 is showing differentiated clinical and preclinical potential, with Phase 2a combo data and myelopreservation readouts both expected in Q2 2020.· November 7, 2019
- Phase 2a expansion data for ALRN-6924 plus palbociclib in MDM2-amplified cancers remained on track for Q2 2020.
- Interim combo results at ESMO covered 26 patients and showed 4.4 months median PFS in 17 heavily pretreated liposarcoma patients, with a 73% 12-week PFS rate.
- The company advanced ALRN-6924 into a Phase 1b/2 myelopreservation trial in p53-mutant small cell lung cancer and added two expansion cohorts.
- Management said the cash runway was unchanged despite reallocating capital from early discovery to myelopreservation.
- Oncology strategy stayed focused on two programs around 6924, with management emphasizing biomarker-driven patient selection and a differentiated safety profile.
For third quarter 2019, Aileron reported R&D expense of $4.5 million versus $4.3 million in the third quarter of 2018, and G&A expense of $3.4 million versus $3.2 million a year ago. Net loss was $7.7 million, or $0.28 per share, compared with a net loss of $7.4 million, or $0.50 per share, in the prior-year quarter. Cash, cash equivalents and investments were $24.6 million as of September 30, 2019, up from $20.7 million at December 31, 2018, and management said this should fund operations into the fourth quarter of 2020. No revenue figure was reported on the call.
Manuel Aivado framed the quarter as the result of a major strategic reset since he became CEO, saying the company refocused on two clinical programs for ALRN-6924 after reassessing the business. He emphasized that 6924 is being developed both as a combination therapy with palbociclib in MDM2-amplified cancers and as a myelopreservation agent in p53-mutant cancers, and repeatedly described the drug as unique and differentiated. His tone was confident and forward-looking, with multiple milestones expected in the first half of 2020.
Rick Wanstall said third-quarter 2019 R&D expense was $4.5 million, mainly due to higher clinical development costs for 6924, while G&A was $3.4 million. He reported a net loss of $7.7 million and cash, cash equivalents and investments of $24.6 million at quarter-end. He also said that balance should fund operations into the fourth quarter of 2020, indicating no near-term change to the runway despite the capital reallocation into myelopreservation.
Analysts focused on the myelopreservation program, asking about the FDA path, the relevance of G1 Therapeutics’ data, and what would count as success in Aileron’s studies. Management said it views G1 as a helpful regulatory precedent, but stressed 6924’s different mechanism and biomarker-based patient selection; they also pointed to potential benefits from better chemotherapy delivery and possible immune effects. Another thread was whether Aileron would expand the palbociclib combination beyond liposarcoma; management said no additional combination programs were imminent and that the company is staying focused on the two current programs.
The bullish case from this call is that 6924 is generating signals in two separate settings: combination oncology and chemotherapy protection. Management highlighted positive interim combo data, faster enrollment, and a clear path to Q2 2020 readouts, while also saying the myelopreservation program has been expanded without shortening cash runway.
The main risks are that the company is still early and has not shown objective responses in the combo study, only disease control metrics so far. The myelopreservation program is still in Phase 1b/2, the regulatory path is being inferred from another company’s precedent, and management noted that further steps depend on resource availability.

A “Sell” may be a pre-scheduled 10b5-1 plan sale rather than a discretionary decision — read insider selling with that in mind.
