Multiple myeloma specialists have spent the past several years absorbing a wave of new T-cell–engaging bispecific antibodies, and the conversation has now shifted from whether these agents work to how community practices without academic infrastructure can safely deliver them. That shift was the focus of a Stakeholder Interchange convened by The American Journal of Managed Care® (AJMC®) on July 28, 2026, in Houston, Texas, part of this year’s series examining bispecific antibody adoption in early relapse relapsed/refractory multiple myeloma (RRMM).
The discussion, moderated by Robert Z. Orlowski, MD, PhD, professor of Lymphoma/Myeloma at The University of Texas MD Anderson Cancer Center, brought together 9 faculty members spanning academic medical centers and community oncology practices across the Houston metropolitan area. Four participants were from UTHealth Houston and Memorial Hermann Cancer Center–Texas Medical Center: Adan Rios, MD; Sara Taveras Alam, MD; Natalie Rafaeli, MD; and Frances Cervoni-Curet, MD. They were joined by Sarvari Yellapragada, MD, of MD Anderson; Branden Hsu, MD, of Texas Oncology–Houston Memorial City; and Rammurti “Ram” Kamble, MD, of Texas Oncology–Deke Slayton Cancer Center in Webster. Rounding out the group were pharmacists Thomas Pessia, PharmD, of Texas Oncology in The Woodlands, and Christina Rivera, PharmD, of Houston Methodist.
Orlowski framed the discussion around a rapidly evolving treatment landscape: teclistamab (Tecvayli; Johnson & Johnson) plus daratumumab (Darzalex; Johnson & Johnson) is now a category 1 recommendation per National Comprehensive Cancer Network (NCCN) guidelines after just 1 prior line of therapy,1 based on the MajesTEC-3 regimen,2 provided patients have already received lenalidomide and a proteasome inhibitor, while chimeric antigen receptor (CAR) T-cell therapy has also moved earlier, with ciltacabtagene autoleucel, or cilta-cel (Carvykti; Legend/Johnson & Johnson) available as early as second line and idecabtagene vicleucel, or ide-cel (Abecma; Bristol Myers Squibb) as early as third line. With no formal sequencing guidance from NCCN, panelists spent much of the evening working through how they are choosing between these options in practice—and what needs to change operationally to deliver bispecifics safely outside the hospital.
Bispecifics vs CAR T: An Evolving Decision Process
The panel’s opening exchange centered on where teclistamab- or talquetamab-based regimens fit relative to CAR T-cell therapy, now that both are approved in earlier relapse. For Rios, the appeal of bispecific antibodies is fundamentally about access. “These antibodies have more degree of affinity for their target. They are more effective in triggering the T-cell responses,” Rios said, adding that “the availability off the shelf is going to be a great advantage in overcoming the barriers of the CAR T.”
Kamble described the second-line decision as genuinely unsettled. “Second line is a huge problem,” he said. “You want to give CAR-T, but you can’t give it to everybody—very select patients. If you can get CAR-T, then it makes sense” to pursue it before defaulting to a bispecific-based regimen.
Yellapragada agreed that dosing schedules are narrowing whatever edge that CAR T-cell therapy retains, particularly as maintenance intervals on bispecifics stretch from weekly to monthly. “I think as we move towards time-limited therapy, both the risk of infections as well as the pressure on the [myeloma] cell to mutate as you keep on exposing it to BCMA therapy, both those risks—theoretical risks—will reduce,” she said. For patients with aggressive disease, “we don’t often have that luxury of time to get to CAR right away.” This makes use of bispecific antibodies a more practical bridge.
“It’s crazy how quickly it’s evolving,” Rafaeli said, summing up the pace of change. “It’s really difficult to keep up, to be honest.” For patients who are candidates for both types of treatment, sequencing questions remain.
Pessia described how such a case is unfolding in his practice. “We’re actually trying to get a talquetamab regimen right now for one of our patients over teclistamab,” he said. Unlike teclistamab, which targets B-cell maturation antigen (BCMA) on myeloma cells and CD3 on T cells,3 talquetamab (Talvey; Johnson & Johnson) targets GPRC5D on myeloma cancer cells and CD3 on healthy T cells.4 The physician treating the patient is concerned that giving a BCMA-directed bispecific would “basically ruin” the chances of CAR T-cell therapy working later on, should the patient relapse. Evidence presented last year at the American Society of Hematology supports this concern.5
“So, he’s kind of holding that CAR-T in his back pocket for that reason,” Pessia said.
Building Outpatient Capacity Looks Different Across Houston
Asked about their experience initiating step-up dosing, panelists described a patchwork of approaches shaped as much by geography and hospital partnerships as by clinical judgment. Hsu, practicing on Houston’s west side, said his group has not yet been able to bring step-up dosing in-house. “For a community, I’ve just been referring everybody to the medical center. We just don’t have the capability at our local hospitals for step-up dosing, and I don’t think there are any plans on the west side of Houston to have any hospitals certified,” he said, referring to meeting requirements of a Risk Evaluation and Mitigation Strategy (REMS).6
Kamble described a more advanced model at Texas Oncology’s Deke Slayton Cancer Center, where step-up dosing now happens largely without full hospital admission. “We do that step-up dosing for the majority of Texas Oncology...we are hospitalizing only for 23-hour observation, and not seeing much problem with this,” he said, comparing the current anxiety around bispecifics to how oncologists once treated tumor lysis syndrome as a major event. “That’s where we will be in a few years’ time with these things.”
Pessia’s Woodlands practice relies on proximity to a partner hospital. “We’re lucky because Memorial Hermann is literally right across the parking lot, so we can transfer the patient over there fairly quickly and easily,” he said of managing cytokine release syndrome (CRS) events during step-up.
At Houston Methodist, Rivera described a hybrid approach designed to shorten inpatient time without sacrificing safety. “We do a hybrid. The patients go inpatient, and then before we even start inpatient step-up dosing, we’ve already obtained the outpatient insurance approval...they start inpatient and they go outpatient quite quickly,” she said.
Memorial Hermann–Texas Medical Center, where Rios, Taveras Alam, Rafaeli, and Cervoni-Curet practice, has moved more cautiously. “We started fairly early with the bispecifics, so we were educated by the pharmaceutical industry, and at the time the intent was really to do inpatient,” Rios said. “We have continued that practice, and we’re now moving slowly to more outpatient.”
Rafaeli said disease burden and socioeconomic factors, more than institutional protocol, drive that decision on a case-by-case basis. “The burden of disease and kind of the socioeconomic situation, health literacy factors into our decision, whether to start inpatient or outpatient.”
Taveras Alam said her team is following the same trajectory, citing caregiver support and disease burden as the operative variables.
Patient Selection Comes Down to Caregivers, Disease Burden—and a Hard Question About Who Gets Left Out
Key Takeaways
Bispecific antibodies are moving earlier in the treatment sequence, and the Houston experts discussed weighing teclistamab plus daratumumab against CAR T-cell therapy in second-line disease. They cited off-the-shelf availability as an advantage over CAR T’s manufacturing delays.
Caregiver access and disease burden, more than academic-vs-community setting, are emerging as the dominant eligibility criteria for outpatient step-up dosing—along with hard questions about patients who lack a support system.
Reimbursement and staff training remain obstacles to adoption, from emergency departments that cannot keep straight which oncology drug requires which rescue medication, to payers denying prophylactic tocilizumab in favor of unavailable biosimilars.
When Orlowski turned the discussion to eligibility criteria for outpatient administration, Rafaeli offered what she framed as her group’s consensus hierarchy. “I think our group will probably agree that disease burden is number one in terms of the decision for outpatient...insurance status does play a very big role,” she said, ranking a combination of patient health literacy and caregiver access as a close third, “because if the patient doesn’t understand what they’re submitting themselves to, what those side effects are going to be, the risk of infections, which we know are very high.”
Hsu tied eligibility directly to hospital readiness. “If you don’t have the hospital support for any problems and we have to send the patient to the [emergency department], it’s going to be a waste of the patient’s effort.” He and Rios both argued that reimbursement for prophylactic tocilizumab, if secured, would make outpatient administration close to routine. “I think that’s the direction, right? I think that’s what everybody’s doing in the next couple years,” Hsu said.
Pessia challenged that consensus, citing the cost of prophylactic tocilizumab. “Why are we doing studies on prophylactic [tocilizumab] and not prophylactic [dexamethasone]? Dex is...a whole lot cheaper than toci,” he said, although he agreed that patient selection is the most important factor. “I don’t think that every patient is good for a bispecific.”
The panel’s most pointed exchange concerned patients who lack reliable caregiver support. Kamble described a screening approach he uses in the first minutes of every new bispecific consultation. “The 2 questions I ask within 5 minutes: Did you walk from the parking lot? And who do you live with? That helps me so much to put my energy into perspective rather than just wasting it.”
