What C4 Therapeutics, Inc. reported on August 11, 2026

The quarter ending June 30, 2026, against the same quarter a year earlier.

These are single quarters, not a trailing year — the figures elsewhere on this site cover twelve months and will be much larger. A seasonal business swings a long way between the two: ServiceNow earns $2.0B of free cash flow in its December quarter and $0.5B in its June one.

Compared against the same quarter a year earlier, not against an analyst forecast. A “beat” or “miss” needs a consensus estimate, which is licensed data we do not carry — and getting it wrong is worse than leaving it out.

What management said

“The first half of 2026 was a period of execution for cemsidomide, our next-generation IKZF1/3 degrader, and our clinical development plan. At the EHA Congress in June, we presented clinical data that further supported cemsidomide’s differentiated and potential best-in-class profile for the treatment of relapsed refractory multiple myeloma. In addition, insights from our June KOL webinar underscored the importance of IKZF1/3 degradation as a foundational mechanism in multiple myeloma and highlighted the potential for next-generation IKZF1/3 degraders to become a cornerstone therapy across the disease continuum,”

What C4 Therapeutics, Inc. does

Cemsidomide is an investigational, next-generation orally bioavailable MonoDAC ® degrader (molecular glue) of IKZF1/3, transcription factors foundational to multiple myeloma biology. Data from the fully enrolled Phase 1 trial show cemsidomide’s differentiated safety and tolerability profile and potentially class-leading anti-myeloma activity that supports the potential for durable outcomes. About the MOMENTUM Trial MOMENTUM (Multi-center trial Of cemsidoMidE iN relapsed/refracTory mUltiple Myeloma) is a Phase 2, open-label, single-arm study to evaluate the efficacy and safety of cemsidomide in combination with dexamethasone in patients with relapsed/refractory multiple myeloma. Data from the Phase 1 trial identified 100 µg as the recommended Phase 2 dose. The primary endpoint is overall response rate per International Myeloma Working Group response criteria, as assessed by an independent review committee. Approximately 100 patients who have received at least three prior anti-myeloma regimens that must have included an IKZF1/3 degrader, a proteasome inhibitor, an anti-CD38 antibody, and a T-cell engager or CAR-T therapy will be enrolled in the trial. More information is available at clinicaltrials.gov (NCT07284758).
