And we believe this is only the beginning. This approval validates years of scientific research and strengthens our confidence in the potential of this approach as we continue to advance our innovative pipeline on behalf of patients with significant unmet needs.\u201d<\/p>\n<p>\nApproval of ZENBEXUS is based on results from the Phase 3 EXCALIBER-RRMM trial evaluating ZENBEXUS, daratumumab and hyaluronidase-fihj and dexamethasone (ZDd; n=207) compared to daratumumab, bortezomib and dexamethasone (DVd; n=213) in patients with RRMM.<sup>1<\/sup> At a median follow-up of 16 months, results showed treatment with ZDd demonstrated a statistically significant improvement in one of the dual primary endpoints of minimal residual disease (MRD)-negative complete response (CR) in 41% of patients (n=85; 95% CI: 34-48) vs. 21% of patients (n=44; 95% CI: 15-27) treated with DVd (p &lt; 0.0001).<sup>1<\/sup> MRD-negativity is among the deepest measures of response in multiple myeloma and is considered predictive of improved progression-free survival (PFS).<sup>2<\/sup> This FDA decision marks the first approval in relapsed or refractory multiple myeloma based on MRD-negative CR.<\/p>\n<p>\n\u201cThe FDA approval of iberdomide marks the anticipated arrival of a new therapeutic class for relapsed or refractory multiple myeloma and has the potential to make a meaningful difference for patients,\u201d said Sagar Lonial, MD, FACP, FASCO, EXCALIBER-RRMM lead investigator and chief medical officer of the Winship Cancer Institute of Emory University. \u201cThe strong results observed with the CELMoD-based combination within a familiar triplet approach creates the potential for a new treatment foundation in multiple myeloma.\u201d<\/p>\n<p>\nThe combination of ZDd was observed to have a safety profile that is expected of the combination, with 7.8% of patients discontinuing ZDd due to adverse reactions.<sup>1<\/sup> Among the key safety findings, ZDd can cause serious, life-threatening, or fatal infections and severe neutropenia.<sup>1<\/sup> Neutropenia and infections in patients who received ZDd occurred at a rate of 90.2% and 78.9%, respectively, leading to few discontinuations (1% and 1.5%, respectively).<sup>1<\/sup> The most common adverse reactions (\u226520%) in the ZDd arm and DVd arm, respectively, were upper respiratory tract infection (54% and 52%), fatigue (36% and 33%), musculoskeletal pain (35% and 33%), pneumonia (34% and 17%), diarrhea (33% and 36%), motor dysfunction (26% and 17%), rash (26% and 15%), sleep disorder (25% and 28%), hypogammaglobulinemia (24% and 12%), COVID-19 (23% and 16%), and constipation (20% and 22%).<sup>1<\/sup> Serious adverse reactions in \u22652% of patients included pneumonia (26%), upper respiratory tract infection (6.4%), second primary malignancy (5.9%), neutropenia (4.9%), febrile neutropenia (3.9%), COVID-19 (4.4%), and sepsis (2.9%).<sup>1<\/sup> Fatal adverse reactions occurred in 10 patients (4.9%) who received ZENBEXUS.<sup>1<\/sup> Sepsis (1.5%) was the only fatal drug reaction that occurred in more than 1 patient.<sup>1<\/sup> The following fatal adverse reactions occurred in 1 patient each: listeria encephalitis, influenza, lung adenocarcinoma, cardiac arrest, large intestine perforation, metabolic acidosis, and respiratory failure.<sup>1<\/sup><\/p>\n<p>\n\u201cThe goal for every person living with multiple myeloma is not simply to live longer, but to live well,\u201d said Heather Cooper Ortner, president and chief executive officer of the International Myeloma Foundation. \u201cThat is why it is important to have access to effective therapeutic options, particularly in the community setting where the majority of myeloma care is delivered. This approval represents an important step forward by expanding treatment options for patients facing their first relapse. Every new option gives patients and their healthcare teams additional choices as treatment needs evolve, as well as renewed hope for the future.\u201d<\/p>\n<p>\nZENBEXUS was granted Breakthrough Therapy designation and accelerated approval based on MRD-negative CR at any time in the EXCALIBER-RRMM study.<sup>1<\/sup> This review was conducted under the FDA\u2019s Project Orbis initiative, which enables concurrent review by the health authorities in several other countries.<\/p>\n<p>\nWhile ZENBEXUS is the first FDA approved CELMoD therapy, a New Drug Application for mezigdomide, an investigational CELMoD, in combination with carfilzomib and dexamethasone is also currently under review with the FDA with a Prescription Drug User Fee Act target date of May 13, 2027.<\/p>\n<p>\nBristol Myers Squibb offers various programs and resources to address the needs of patients and caregivers, and provides support that allows for access to therapies, including ZENBEXUS<i>.<\/i><\/p>\n<p><b><span class=\"bwuline\">About EXCALIBER-RRMM<br \/>\n<br \/><\/span><\/b>EXCALIBER-RRMM (NCT04975997) is a Phase 3, multicenter, two-stage, randomized, open-label study evaluating the efficacy and safety of ZENBEXUS (iberdomide) in combination with daratumumab and hyaluronidase-fihj and dexamethasone (ZDd) versus daratumumab, bortezomib, and dexamethasone (DVd) in patients with relapsed or refractory multiple myeloma (RRMM).<sup>2<\/sup> The study included a dose optimization stage and was designed to assess dual-primary endpoints of minimal residual disease (MRD) negativity and progression-free survival (PFS), with additional secondary endpoints including overall survival (OS), overall response rate (ORR), safety and sustained MRD negativity.<sup>2<\/sup> The study remains ongoing to assess the primary endpoint of PFS. Eligible participants included adults with 1 to 2 prior lines of anti-myeloma therapy and progressive disease.<sup>2<\/sup> A total of 939 patients were randomized.<sup>1<\/sup> The primary efficacy population for MRD negativity included the first 420 patients randomized to the ZENBEXUS (1 mg) + Dd arm (n=207) or the comparator daratumumab, bortezomib, and dexamethasone (DVd) arm (n=213).<sup>1<\/sup> Treatment in both arms was administered until disease progression or unacceptable toxicity.<sup>1<\/sup><\/p>\n<p>\nThis approval, the first in RRMM based on MRD-negative complete response (CR), marks the first public disclosure of MRD-negative CR data from the EXCALIBER-RRMM trial. The MRD data were first disclosed at the time of approval to preserve the integrity of the study while additional endpoints mature.

These agents, known as immunomodulatory drugs (IMiDs), helped establish the current standard of care in the treatment of this disease, which remains without a cure. BMS is building on this foundation with several investigational protein degraders in clinical trials, leveraging three different modalities including cereblon E3 ligase modulators (CELMoDs), ligand-directed degraders (LDDs), and degrader antibody conjugates (DACs).

All statements that are not statements of historical facts are, or may be deemed to be, forward-looking statements. Such forward-looking statements are based on current expectations and projections about our future financial results, goals, plans and objectives and involve inherent risks, assumptions and uncertainties, including internal or external factors that could delay, divert or change any of them in the next several years, that are difficult to predict, may be beyond our control and could cause our future financial results, goals, plans and objectives to differ materially from those expressed in, or implied by, the statements. These risks, assumptions, uncertainties and other factors include, among others, whether ZENBEXUS<sup>\u2122<\/sup>(iberdomide) in combination with daratumumab and hyaluronidase-fihj<\/i><i>and dexamethasone (ZDd)<\/i><i>for the indication described in this release will be commercially successful, any marketing approvals, if granted, may have significant limitations on their use, and, that continued approval of ZENBEXUS<sup>\u2122<\/sup> (iberdomide) in combination with daratumumab and hyaluronidase-fihj and dexamethasone (ZDd) described in this release may be contingent upon verification of progression-free survival, the dual primary endpoint of the EXCALIBER-RRMM trial and potential further verification and description of clinical benefit in confirmatory trials. No forward-looking statement can be guaranteed. Forward-looking statements in this press release should be evaluated together with the many risks and uncertainties that affect Bristol Myers Squibb\u2019s business and market, particularly those identified in the cautionary statement and risk factors discussion in Bristol Myers Squibb\u2019s Annual Report on Form 10-K for the year ended December 31, 2025, as updated by our subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the Securities and Exchange Commission.
