T Cell Lymphomas

LA JOLLA, CALIF. – In patients with relapsed peripheral T-cell lymphoma, the goal before moving to transplant is achieving complete or near-complete remission, according to Steven M. Horwitz, MD, of Memorial Sloan Kettering Cancer Center, New York.

“If you’re really trying to go to transplant, you want a complete remission or close to it. So that’s often been combination chemotherapy. But I think what we’re learning is, when some of the newer agents are combined, we’re seeing higher complete response rates. And we’re doing a better job at picking subtype specific approaches,” Dr. Horwitz said in a video interview at the annual T-cell Lymphoma Forum.

Dr. Horwitz also explored the role for reduced-intensity regimens in older patients, the use of radiation conditioning, and which new agents look most promising in peripheral T-cell lymphoma.

Dr. Horwitz had previously disclosed financial relationships with Celgene, Forty Seven, Huya Bioscience International, Infinity, Kyowa Hakko Kirin, Millennium, Seattle Genetics, and Takeda. The T-Cell Lymphoma Forum is held by Jonathan Wood & Associates, which is owned by the same company as this news organization.

The Food and Drug Administration has received 414 reports of cases of breast implant–associated anaplastic large cell lymphoma (BIA-ALCL), including nine deaths.

This figure includes all medical device reports received by the agency between 2011 and September 2017. The FDA recently provided an update on ALCL linked to breast implants and an estimate of lifetime risk of developing ALCL.

Based on available medical literature, the lifetime risk of developing BIA-ALCL for patients with textured breast implants ranges from 1 in 3,817 to 1 in 30,000, according to the update.

Of the 272 reports with data on surface type, 242 were textured implants and 30 were smooth implants. In addition, 413 reports include information on the implant fill type: 234 used silicone gel and 179 were saline filled.

“The FDA has been closely tracking the relationship between breast implants and a rare type of non-Hodgkin’s lymphoma since we first identified this possible association. We’ve been working to gather additional information to better characterize and quantify the risk so that patients and providers can have more informed discussions about breast implants,” said Binita Ashar, MD, director of the division of surgical devices in the FDA’s Center for Devices and Radiological Health. “As part of that effort, we are working to update and enhance the information we have on this association, including updating the total number of known cases of BIA-ALCL and the lifetime risk of developing BIA-ALCL as reported in medical literature.”

The possible association between breast implants and the development of anaplastic large cell lymphoma (ALCL) was first identified in 2011. At that time, there were not enough cases of to determine what factors increased a patient’s risk of developing the disease. As more information became available, the World Health Organization designated BIA-ALCL as a T-cell lymphoma that can develop following breast implants.

LA JOLLA, CALIF. – When patients with peripheral T-cell lymphoma (PTCL) experience relapse, consider an allogeneic stem cell transplant or clinical trial, investigators advised.

Patients with relapsed PTCL have generally dismal outcomes, with a median progression-free survival (PFS) of 3.7 months and a median overall survival (OS) of just 6.5 months, according to one study (J Clin Oncol. 2013 Jun 1;31[16]:1970-6).

She outlined her center’s approach for treating patients with relapsed or refractory PTCL, following a case presentation by Royal Marsden fellow Matthew Cross, MD.

Complex disease, multiple therapies

The patient was a 71-year-old woman who in 2007 had a diagnosis of asymptomatic stage 4A follicular lymphoma managed with observation; in 2010, she was diagnosed with a CD30-positive PTCL not otherwise specified with ongoing low-level bone marrow involvement with follicular lymphoma.

She initially was treated elsewhere with R-CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab) and had a response after four cycles; however, she had progression with new intra-abdominal nodal sites by the sixth cycle and then was started on two cycles of ESHAP (etoposide, methylprednisolone, high-dose cytarabine, and cisplatin), but she had further progression by May 2011 and opted to forgo additional treatment.

By July 2011, however, she became highly symptomatic with new pruritic rashes on her legs, abdominal pain, and distention. She was referred to the Royal Marsden Hospital, where she was eventually diagnosed with angioimmunoblastic T-cell lymphoma (AITL) with an Epstein-Barr virus–negative clonal large B-cell proliferation in her bone marrow.

She was treated with gemcitabine plus methylprednisolone and prophylactic intrathecal methotrexate and had an “excellent clinical and radiological response,” Dr. Cross said.

A subsequent bone marrow biopsy showed marked hypocellularity but no evidence of either T-cell of B-cell lymphomas.

An autologous stem cell transplant was planned, but two attempts at harvesting peripheral blood stem cells – including one with plerixafor (Mozobil) – failed, and a PET scan within 3 months showed signs of early progression.

In April 2012, the patient was started on romidepsin (Istodax) and had a 1-year remission. But in April 2013, a repeat biopsy again showed CD30-positive AITL. Based on the CD30 positivity, the patient was started on brentuximab vedotin (Adcetris) in May 2013. She was observed to have progression in inguinal nodes in January 2014; she was treated with local radiotherapy and continued on brentuximab but had further progression in June 2014. At that time, she had additional gemcitabine-based combination chemotherapy and had stable disease for 10 months.

In March 2015, she received lenalidomide for further progression but could not tolerate the drug. She died in September 2015, 5 years after diagnosis and 4.5 years after frontline therapy failed.

Therapeutic rationale

Dr. Dearden walked through the choices that she, along with Dr. Cross and their colleagues, made in treating the patient. They chose gemcitabine-based regimens for salvage therapy because of the drug’s efficacy across various forms on non-Hodgkin and Hodgkin lymphoma, she said.

However, a randomized, phase 3, noninferiority trial in the United Kingdom comparing GEM-P (gemcitabine, cisplatin, and methylprednisolone) with CHOP for first-line therapy of PTCL was halted at the interim analysis because GEM-P had not meet the primary endpoint, she said. Results of that trial have not been published to date.

“Clearly, if it’s the patients who do well, often it’s because they achieve a good enough remission to be able to proceed to some sort of consolidation therapy with autologous or allogeneic stem cell transplants, and I think auto-graft is probably accepted for the younger, fitter patients with relapsed chemo-sensitive disease,” she said.

Three-year survival rates for autologous hematopoietic stem cell transplantation range from 36% to 58% and are better than those seen with chemotherapy alone, she said.

“The problem of course is that not many patients receive the planned auto-graft, even if that’s the intention, either because of failure to respond to salvage regimen or early disease progression, which happens before the transplant is able to take place,” she said,

A reasonable alternative for patients with relapsed/refractory PTCL is allogeneic transplantation, as shown in a 2008 study.

Among 77 patients – 57 of whom had received myeloablative conditioning, 31 of whom were in complete remission, and 26 of whom had partial response at the time of transplants – the 5-year treatment-related mortality rate was 33%. However, the 5-year event-free and overall survival rates were 53% and 57%, respectively. Patients with AITL had especially good outcomes (J Clin Oncol. 2008 May 10;26[14]:2264-71).

“In an ideal world, if our patient had been a suitable candidate for an allo-transplant, it’s what we would have tried to undertake,” Dr. Dearden said.

Dr. Dearden recommended that all patients with relapsed or refractory PTCL be considered for clinical trials. For fit patients in first relapse, combination platinum-based chemotherapy followed by autologous or allogeneic transplant may be effective.

For patients not eligible for transplant or with chemotherapy-refractory disease, she recommended trying the following monotherapy approaches: pralatrexate for patients with PTCL not otherwise specified, histone deacetylase inhibitors or 5-azacytidine for AITL, brentuximab vedotin for anaplastic large cell lymphoma, and pembrolizumab for natural killer/T-cell lymphomas.

Although two lines of intensive chemotherapy had failed the case patient within 6 months of diagnosis, she still survived for 5 years with sequential monotherapies, Dr. Dearden noted.

“I use to say to her, ‘You just need to stay one drug ahead of your disease.’ And she was well, she had a very good quality of life for a period of time, and if you can deliver a treatment that is effective for a patient, it will extend their survival,” Dr. Dearden said.

LA JOLLA, CALIF. – Patients with mycosis fungoides are at increased risk for developing other cancers and should be screened for second primary and hematologic malignancies, results of a cancer registry survey suggest.

A study of data on 6,196 patients included in 18 population-based cancer registries comprising the SEER-18 (Surveillance, Epidemiology, and End Results 18) database who were diagnosed and followed from 2000 to 2014 showed that 514 (8.3%) developed second cancers, compared with the 70.8 secondary malignancies that would be expected in the general population. This difference translated into a standardized incidence ratio (SIR) of 7.3, reported Amrita Goyal, MD, and Aleksandr Lazaryan, MD, PhD, of the University of Minnesota, Minneapolis.

LA JOLLA, CALIF. – Combining a radio-labeled, anti-CD25, monoclonal antibody with BEAM chemotherapy appears to be an effective and safe conditioning regimen prior to autologous stem cell transplant in patients with peripheral T-cell lymphoma (PTCL), investigators report.

In a phase 1 trial, median progression-free survival (PFS) was 10.6 months for patients treated with the yttrium-90–labeled, chimeric, anti-CD25 antibody basiliximab (Simulect) at one of three dose levels plus standard dose BEAM (carmustine, etoposide, cytarabine, and melphalan), said Jasmine Zain, MD, of the City of Hope Medical Center in Duarte, Calif.

There have been no significant cases of delayed transplant engraftment or unexpected increases in either mucositis or infectious complications, she said at the annual T-cell Lymphoma Forum.

In a phase 1 trial, median progression-free survival (PFS) was 10.6 months for patients treated with the yttrium-90–labeled, chimeric, anti-CD25 antibody basiliximab (Simulect) at one of three dose levels plus standard dose BEAM (carmustine, etoposide, cytarabine, and melphalan), said Jasmine Zain, MD, of the City of Hope Medical Center in Duarte, Calif.

There have been no significant cases of delayed transplant engraftment or unexpected increases in either mucositis or infectious complications, she said at the annual T-cell Lymphoma Forum.

LA JOLLA, CALIF. – For patients with relapsed peripheral T-cell lymphoma, allogeneic stem cell transplants offer the best chance for achieving remission or even a cure, making the choice of therapies as bridges to transplant essential for getting there.

“The goal is to get to transplant with a curative intent. In our hands, that’s mostly allo[geneic] and mostly in the relapsed setting,” Steven M. Horwitz, MD, from the lymphoma service at Memorial Sloan Kettering Cancer Center, New York, said at the annual T-cell Lymphoma Forum. “The best bridge to transplant is the one that gets you across safely.”

Better approaches by subtype?

The subtype of PTCL also appears to matter. Three approved agents for relapsed/refractory PTCL – belinostat (Beleodaq), romidepsin (Istodax), and pralatrexate (Folotyn) – are associated with CR rates of 11%, 15%, and 11%, respectively. But one PTCL subtype, anaplastic large cell lymphoma, appears particularly sensitive to treatment with brentuximab vedotin (Adcetris), with CR rates of 59%, Dr. Horwitz noted.

In a 2014 study, investigators reported that of the nine patients with anaplastic large cell lymphoma positive for anaplastic lymphoma kinase and treated with the anaplastic lymphoma kinase inhibitor crizotinib (Xalkori), all had a CR, with response durations stretching pasting 40 months in one patient, and past 30 months in two others (J Natl Cancer Inst. 2014 Feb;106[2]:djt378).

A different subtype, natural killer/T-cell lymphoma, was shown to be responsive to immunotherapy with pembrolizumab (Keytruda) in seven patients, with CRs in five and partial remissions in two. Responses to pembrolizumab in this PTCL subtype may be adequately long for getting patients to transplant, Dr. Horwitz said.

For some patients with angioimmunoblastic T-cell lymphoma, therapy with epigenetic modifying agents, such as decitabine or a combination of romidepsin and lenalidomide (Revlimid), with or without carfilzomib (Kyprolis), may also be effective bridges to transplant, based on the best available evidence.
 

Timing may also matter

Dr. Horwitz cautioned that for patients with cutaneous T-cell lymphoma, the investigational agent mogamulizumab, which was shown in the MAVORIC (Study of KW-0761 versus Vorinostat in Relapsed/Refractory CTCL) trial to offer significantly better PFS compared with vorinostat (Zolinza), also appears to increase the chance that patients will develop high-risk, potentially fatal graft vs. host disease posttransplant.

The risk appears to be slightly lower among patients who received the last dose of mogamulizumab more than 50 days before undergoing SCT, he noted.

Although there is no strong evidence to support it, Dr. Horwitz noted that the timing of most other therapies may also be important to the success of SCT. “I think we have seen that when patients have a big [long] break before transplant, the relapse rate is high, and I have a personal preference for using regimens that you can continue up close to transplant, because I think we lose [fewer] patients getting ready for that,” he said.

Dr. Horwitz had previously disclosed financial relationships with Celgene, Forty Seven, Huya Bioscience International, Infinity, Kyowa Hakko Kirin, Millennium, Seattle Genetics, and Takeda. The T-Cell Lymphoma Forum is held by Jonathan Wood & Associates, which is owned by the same company as this news organization.

LA JOLLA, CALIF. – The words “rapid approval” and “Food and Drug Administration” rarely appear in the same sentence. But despite that perception, the pace of hematologic drug development has been accelerating over the last several years, according to an agency staffer.

“FDA is committed toward the expedited development of safe and effective therapies for serious and life-threatening diseases,” R. Angelo de Claro, MD, of the FDA’s Office of Hematology and Oncology Products said at the annual T-cell Lymphoma Forum. Dr. de Claro outlined his agency’s efforts to accelerate approval of drugs for treatment of T-cell malignancies.
 

Hematologic drug bonanza

In 2017 alone, the FDA approved 17 agents for new or expanded indications for hematologic malignancies, including brentuximab vedotin (Adcetris) for anaplastic large cell lymphoma (ALCL) and CD30-positive mycosis fungoides (MF).

Approval was based on a 56% objective response rate for brentuximab vedotin versus 12% for physician’s choice in a phase 3 trial (ALCANZA) of 131 patients with mycosis fungoides or primary cutaneous ALCL. All patients had received one prior systemic therapy and were randomized (1:1) to receive either brentuximab vedotin or the physician’s choice of methotrexate or bexarotene.

Dr. de Claro noted that in the ALCANZA trial, patients were required to have one or more biopsy samples with at least 10% CD30 expression, but among 184 patients with MF screened for the trial, 32% were ineligible because of less than 10% CD30 expression. The FDA therefore requested additional efficacy data for patients with MF with less than 10% CD30 expression and accepted data from two investigator-sponsored trials showing that 35 patients with MF expressing CD30 on 1%-9% of cells had a 31% overall response rate, whereas two patients with no CD30 expression did not have responses.

Who minds the store

Hematology products are under the aegis of the FDA’s Oncology Center of Excellence. Oversight includes benign hematology products, as well as products for hematologic cancers and hematologic support. Hematology and oncology toxicology is monitored by pharmacologists and toxicologists in a separate division, he explained.

“The Oncology Center of Excellence was formally launched in 2017 as part of the 21st century CURES Act. The mission of the Oncology Center of Excellence is to achieve patient-centered regulatory decision making through innovation and collaboration,” he said.

Getting the nod

To get approved, a new therapy requires “substantial” evidence of efficacy and safety. Regular approvals are based on either direct measures of clinical benefits – how a patient “feels, functions, or survives” – or a measure of the effect of a drug on an established surrogate endpoint.

For an accelerated approval, developers must be able to show evidence on either a surrogate or intermediate clinical endpoint that the agent is reasonably likely to offer a benefit and be a meaningful improvement over available therapies. Postapproval trials may be needed to verify the proposed benefits.

FDA accelerated approval programs include:

• Fast track. The pathway requires nonclinical or clinical data demonstrating the potential for addressing an unmet need.
• Breakthrough therapy. This pathway requires preliminary clinical evidence demonstrating substantial improvement over existing available therapies.
• Priority review. These are agents that, if approved, would provide significant improvements in safety or effectiveness.
• Accelerated approval. The drug must demonstrate an effect on an “endpoint reasonably likely to predict clinical benefit over available therapies.”

LA JOLLA, CALIF. – There are several biologic compounds in early clinical development for treatment of patients with T-cell lymphomas, including an antibody-drug conjugate, novel immune checkpoint inhibitor, and bi-specific antibody.

These investigational agents show promising single-agent activity and have the potential to improve clinical responses when combined with combination chemotherapy regimens or other treatments, Ahmed Sawas, MD, of the Center for Lymphoid Malignancies at Columbia University, New York, said at the annual T-cell Lymphoma Forum.
 

AGS67E: Antibody-drug conjugate

AGS67E is an antibody-drug conjugate targeted against CD37, a transmembrane protein preferentially expressed on malignant B cells, T cells, and acute myeloid leukemia cells. In a study published in 2015 in Molecular Cancer Therapeutics, investigators from Agensys (an affiliate of Astellas Pharma) reported that this compound bound to more than 80% of patient-derived T cells in vitro (Mol Cancer Ther. 2015;14[7]:1650-60).

In a phase 1 dose-escalation study reported at the 2017 International Conference on Malignant Lymphoma in Lugano, Switzerland, Dr. Sawas and his colleagues found that patients with B-cell and T-cell malignancies, including cutaneous T-cell lymphoma and peripheral T-cell lymphoma, tolerated the drug well when it was delivered both with or without growth factor. Neutropenia was the most frequent adverse event and dose-limiting toxicity.

The drug showed single-agent activity in 16 of 53 patients with heavily pretreated non-Hodgkin lymphoma, including a partial response in one of two patients with cutaneous T-cell lymphoma, and partial responses in two of four patients with peripheral T-cell lymphoma. There were no complete responses at any of three dose levels of the drug, with or without growth factor.

TTI-621: Tuck in, macrophages

TT1-621 is a molecule with two functions: It acts as an immune checkpoint inhibitor by blocking CD47, which binds to signal-regulatory protein alpha to produce an antiphagocytic or “do not eat” signal. TTI-621 does not, however, bind to CD47-positive erythrocytes.

In addition to blocking CD47 and the do-not-eat signal, TTI-621 delivers an activating signal to macrophages through Fc gamma receptors, telling them, in effect, “bon appétit.”

In a study presented at the 2017 annual meeting of the American Society of Hematology (Abstract 4076), investigators from City of Hope in Duarte, Calif., and other centers reported that a single direct intratumoral injection of TTI-621 was associated with significant antitumor activity in patients with relapsed or refractory mycosis fungoides and Sézary syndrome, with one of nine patients having a complete response in the injected lesion, and five having decreases in tumor size and/or circulating Sézary cells.

Patients appeared to tolerate this agent very well, with 1 of 18 having a grade 3 increase in white blood cell count. The most commonly reported side effects were fatigue, chills, decreased appetite, headache, injection site pain, and generalized pruritus, each occurring in 3 of the 18 patients.

TTI-621 injection was associated with rapid declines in Composite Assessment of Index Lesion Severity scores in dose-finding studies in patients with heavily pretreated cutaneous T-cell lymphoma, Dr. Sawas said.
 

AFM13: Two for the price of one

AFM13 is a bi-specific antibody that binds to CD30, which is expressed on anaplastic large cell lymphoma cells, as well as Reed-Sternberg cells of classical Hodgkin lymphoma. This antibody also engages CD16A-positive cells, resulting in lysis of CD30-positive tumor cells. It is a specific recruiter of natural killer cells, and does not bind to neutrophils.

In an early biologic effects study of this agent in CD30-positive lymphoid malignancies with cutaneous presentation, Dr. Sawas and his colleagues observed an early response and regression of cutaneous anaplastic large cell lymphoma lesions in a heavily pretreated patient, with progression occurring when the patient went off therapy, and tumors that diminished on reinitiation of therapy that sustained beyond a second discontinuation of therapy. This patient had measurable reductions in lymphoma burden on PET CT scans and improvements in cutaneous lesions. Dr. Sawas did not present safety data for this agent.

AGS67E studies are supported by Agensys. TTI-621 studies are supported by Trillium Therapeutics. The AFM13 study is supported by Columbia University, with Dr. Sawas listed as the sponsor. He did not report potential conflicts of interests. The T-Cell Lymphoma Forum is held by Jonathan Wood & Associates, which is owned by the same company as this news organization.

Patients appeared to tolerate this agent very well, with 1 of 18 having a grade 3 increase in white blood cell count. The most commonly reported side effects were fatigue, chills, decreased appetite, headache, injection site pain, and generalized pruritus, each occurring in 3 of the 18 patients.

TTI-621 injection was associated with rapid declines in Composite Assessment of Index Lesion Severity scores in dose-finding studies in patients with heavily pretreated cutaneous T-cell lymphoma, Dr. Sawas said.
 

AFM13: Two for the price of one

AFM13 is a bi-specific antibody that binds to CD30, which is expressed on anaplastic large cell lymphoma cells, as well as Reed-Sternberg cells of classical Hodgkin lymphoma. This antibody also engages CD16A-positive cells, resulting in lysis of CD30-positive tumor cells. It is a specific recruiter of natural killer cells, and does not bind to neutrophils.

In an early biologic effects study of this agent in CD30-positive lymphoid malignancies with cutaneous presentation, Dr. Sawas and his colleagues observed an early response and regression of cutaneous anaplastic large cell lymphoma lesions in a heavily pretreated patient, with progression occurring when the patient went off therapy, and tumors that diminished on reinitiation of therapy that sustained beyond a second discontinuation of therapy. This patient had measurable reductions in lymphoma burden on PET CT scans and improvements in cutaneous lesions. Dr. Sawas did not present safety data for this agent.

ATLANTA – Intravenous treatment with mogamulizumab, an investigational antibody targeting CC chemokine receptor 4, more than doubled progression-free survival (PFS), compared with oral vorinostat in a phase 3 trial of 372 patients with heavily pretreated cutaneous T-cell lymphoma (CTCL).

After a median of three treatment cycles, median PFS with mogamulizumab was 7.7 months vs. 3.1 months with vorinostat (hazard ratio, 0.53; 95% confidence interval, 0.41-0.69; P less than .0001), Youn H. Kim, MD, reported at the annual meeting of the American Society of Hematology.

Mogamulizumab also topped vorinostat in terms of overall response to treatment (28% vs 5%; P less than 001) and on several quality of life scales, said Dr. Kim, the Joanne and Peter Haas, Jr. Professor for Cutaneous Lymphoma Research at Stanford (Calif.) University. Adverse effects, such as infusion reactions, were expected and manageable, she added.

Mogamulizumab is approved in Japan for treating CTCL and received an FDA breakthrough therapy designation in August 2017.

Based on audits so far, the agency might green-light mogamulizumab for previously treated CTCL by early 2018 – its first approval in the United States, Dr. Kim said in an interview.

Cutaneous T-cell lymphoma responds poorly to treatments that work in other, more common types of non-Hodgkin lymphoma. Moreover, extensive disease can destroy quality of life.

“There’s a major psychosocial impact because if you’re infected, you smell bad,” Dr. Kim said during a press briefing. “Itch is very severe – patients often cannot sleep because of it.”

Mogamulizumab is a humanized monoclonal antibody that targets CC chemokine receptor 4 (CCR4), which facilitates trafficking of lymphocytes to skin and other organs. It is defucosylated, augmenting its toxicity against malignant T cells. In a prior phase 1/2 study in the United States, mogamulizumab showed a tolerable safety profile and a 37% overall response rate – “a good response, considering that other CTCL drugs are usually in the 30% range,” Dr. Kim said.

For the phase 3 study (MAVORIC), 372 patients with previously treated stage IB to stage IVB CTCL (mycosis fungoides or Sézary syndrome) without large-cell transformation received mogamulizumab (1.0 mg/kg IV weekly for 28 days; days 1 and 15 of subsequent 28-day cycles) or vorinostat (400 mg per oral daily). Treatment continued until disease progression or intolerable toxicity. Researchers evaluated PFS based on a global composite response score that covers the skin, blood, lymph nodes, and viscera, in accordance with international consensus guidelines (J Clin Oncol. 2011 Jun 20;29(18):2598-607; doi: 10.1200/JCO.2010.32.0630).

Treatment groups resembled each other at baseline. Most had received three systemic therapies for CTCL, and some had received as many as 18. Median duration of response was 14 months in the mogamulizumab arm and 9 months in the vorinostat arm. Patients tended to respond to mogamulizumab 2 months sooner than to vorinostat (3.3 vs. 5.1 months), Dr. Kim said.

Mogamulizumab also significantly improved quality of life on the Skindex-29 Symptoms (P less than .05), Skindex-29 Function (P less than 05), and FACT-G Functional Well-Being (P less than .05) quality of life scales, which is part of what earned it a breakthrough therapy designation, Dr. Kim said.

MAVORIC is the largest randomized study to compare systemic therapies in CTCL and the first to use PFS as the primary endpoint, Dr. Kim noted. Patients’ level of CCR4 expression was not a criterion for enrollment because CCR4 is consistently and highly expressed in this disease, she noted. Thus, using mogamulizumab to treat CTCL in the United States would not require CCR4 testing.

Joseph M. Connors, MD, who specializes in lymphoid cancers at the BC Cancer Agency, a division of the British Columbia Provincial Health Services Authority, and who was not involved in the study, agreed that these data represent real headway in treating CTCL.

“I can state unequivocally that we just haven’t had effective therapy for CTCL,” he said at the press briefing. “We’ve had treatments that might help patients feel somewhat better, but we’ve had no consensus on a treatment that is right for this disease. These data provide an opportunity to have that consensus. They could create a platform for making further progress.”
