"Receiving FDA orphan drug designation for ICT01 is a significant recognition of ICT01’s innovative therapeutic potential to meet the urgent unmet medical needs of AML patients," said Stephan Braun, MD, PhD, Chief Medical Officer of ImCheck Therapeutics. "This important regulatory milestone reinforces our confidence that ICT01 will become the first immunotherapy for AML patients and supports our goal of rapidly advancing ICT01 into pivotal studies based on the unprecedented results observed in the clinic to date."

In an oral presentation at the 2025 ASCO (Free ASCO Whitepaper) Annual Meeting, ImCheck reported results from the Phase I/II EVICTION study, evaluating ICT01 in combination with azacitidine and venetoclax (Aza-Ven) in newly diagnosed AML patients unfit for intensive chemotherapy. Remarkably high remission rates and a positive overall survival signal were observed across a broad range of molecular subtypes, in particular those that are typically less responsive to Aza-Ven. The combination demonstrated a clinically well-manageable safety profile, with Grade ≥3 adverse events consistent with the expected hematological toxicity of Aza-Ven and AML itself.

"Orphan drug designation is a catalyst," added Pierre d’Epenoux, Chief Executive Officer of ImCheck Therapeutics. "It validates our regulatory strategy, de-risks and supports clinical development acceleration, and sends a strong signal about the unique potential of ICT01 to transform AML treatment as well as other solid tumor indications."

The FDA’s orphan drug designation is granted to drugs and biologics intended for the treatment, diagnosis, or prevention of rare diseases affecting fewer than 200,000 people in the United States. The designation is designed to encourage the development of therapies for underserved patient populations and offers benefits including tax credits for clinical trials, exemption from certain FDA fees, and up to seven years of marketing exclusivity upon approval. Additionally, the designation gives access to regulatory assistance for the drug development process.

About the medical need in AML

Acute myeloid leukemia (AML) remains a significant clinical challenge, particularly for older or unfit patients who cannot tolerate intensive chemotherapy. While the combination of venetoclax and azacitidine has become the standard non-intensive regimen, it is not curative and relapse rates remain high. Most patients are not eligible for stem cell transplantation, often due to age, comorbidities, or insufficient response, and face limited treatment options and poor overall survival. Despite AML’s known sensitivity to immune-mediated control, current immunotherapies targeting PD-1, TIM-3, or CD47 have not delivered meaningful clinical benefit. This underscores the urgent need for novel immuno-oncology approaches. Recently, γ9δ2 T cells, with their cytotoxic activity and unique dual role in both innate and adaptive immunity, have emerged as promising immune modulators. Their association with reduced relapse and prolonged survival, particularly in the post-transplant setting, suggests that enhancing their anti-leukemic potential could offer a meaningful new treatment option for high-risk AML patients.

About ICT01

ICT01 is a humanized, anti-BTN3A (also known as CD277) monoclonal antibody that selectively activates γ9δ2 T cells, which are responsible for immunosurveillance of malignancy and infections. The three isoforms of BTN3A targeted by ICT01 are overexpressed on many solid tumors (e.g., melanoma, urothelial cell, colorectal, ovarian, pancreatic, and lung cancer) and hematologic malignancies (e.g., leukemia and lymphomas) and also expressed on the surface of innate (e.g., γδ T cells and NK cells) and adaptive immune cells (T cells and B cells). BTN3A is essential for the activation of the anti-tumor immune response of γ9δ2 T cells.

As demonstrated by data presented at past AACR (Free AACR Whitepaper), ASCO (Free ASCO Whitepaper), ASH (Free ASH Whitepaper), ESMO (Free ESMO Whitepaper) and SITC (Free SITC Whitepaper) conferences, ICT01 selectively activates circulating γ9δ2 T cells leading to migration of γ9δ2 T cells out of the circulation and into the tumor tissue and triggers a downstream immunological cascade through secretion of pro-inflammatory cytokines, including but not limited to IFNγ and TNFα, further augmenting the anti-tumor immune response. Anti-tumor activity and efficacy of ICT01 have been shown in patients across several cancer indications.

On July 18, 2025 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) for Genentech’s supplemental Biologics License Application (sBLA) for Columvi (glofitamab-gxbm) in combination with gemcitabine and oxaliplatin (GemOx) for the treatment of people with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who are not candidates for autologous stem cell transplant (Press release, Genentech, JUL 18, 2025, View Source [SID1234654440]).

Based on the CRL, the STARGLO data do not provide sufficient evidence to support the proposed second-line DLBCL indication in the U.S. patient population. STARGLO was also intended as a postmarketing confirmatory study to convert the accelerated approval of Columvi in third-line or later DLBCL in the U.S. to full approval. Columvi remains under accelerated approval for people with third-line or later DLBCL. Discussions with the FDA are ongoing to confirm the Phase III SKYGLO study investigating Columvi in combination with Polivy (polatuzumab vedotin-piiq), Rituxan (rituximab), cyclophosphamide, doxorubicin and prednisone for patients with previously untreated large B-cell lymphoma as the new postmarketing requirement.

"While we are disappointed with this outcome, we remain confident in the data supporting the value of Columvi for U.S. patients who have relapsed following initial treatment, and its key role as monotherapy in the third-line setting," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "We are committed to bringing Columvi to more people living with lymphoma and are actively exploring its potential in additional treatment settings, including as frontline therapy."

"For patients with this aggressive form of lymphoma, effective treatment after relapse is paramount. The STARGLO study showed that Columvi-GemOx significantly improves overall survival and could have a positive impact for patients earlier in their treatment journey. This regimen is already approved in over 35 countries, which underscores the urgent need it addresses," said Jeremy Abramson, M.D., director, Jon and Jo Ann Hagler Center for Lymphoma at the Massachusetts General Hospital Cancer Center, and principal investigator of the STARGLO study.

Based on the STARGLO data, this Columvi combination is approved in more than 35 countries, including in the EU, and recommended in clinical practice guidelines including the U.S. National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines).† Data has been submitted to other health authorities around the world for approval consideration. Columvi monotherapy has been approved for use in R/R DLBCL after two or more prior lines of therapy in more than 60 countries worldwide.  

The sBLA is based on results from the Phase III STARGLO study which showed a statistically significant and clinically meaningful 41% reduction in the risk of death (hazard ratio=0.59, 95% confidence interval: 0.40–0.89, p=0.011) in patients treated with Columvi in combination with GemOx. Results were published in The Lancet and two-year follow-up data from the study were presented at the 61st American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting from May 30 – June 3, 2025, where improvements in primary and secondary endpoints were sustained.

About the STARGLO study 

The STARGLO study [GO41944; NCT04408638] is a Phase III, multicenter, open-label, randomized study evaluating the efficacy and safety of Columvi (glofitamab-gxbm) in combination with gemcitabine plus oxaliplatin (GemOx) versus Rituxan (rituximab) in combination with GemOx in patients with relapsed or refractory diffuse large B-cell lymphoma who have received at least one prior line of therapy and who are not candidates for autologous stem cell transplant, or who have received two or more prior lines of therapy. Preclinical research indicated an increased antitumor effect when combining Columvi with GemOx over GemOx alone, so the STARGLO study was initiated to further explore the potential complementary effects of the treatment combination. Outcome measures include overall survival (primary endpoint), progression-free survival, complete response rate, objective response rate, duration of objective response (secondary endpoints), and safety and tolerability. 

About  Columvi (glofitamab-gxbm) 

Columvi is a CD20xCD3 T-cell engaging bispecific antibody designed to target CD3 on the surface of T cells and CD20 on the surface of B cells. Columvi was designed with a novel 2:1 structural format. This T-cell-engaging bispecific antibody is engineered to have one region that binds to CD3, a protein on T cells, a type of immune cell, and two regions that bind to CD20, a protein on B cells, which can be healthy or malignant. This dual-targeting brings the T cell in close proximity to the B cell, activating the release of cancer cell-killing proteins from the T cell. Columvi is part of Genentech’s broad and industry-leading CD20xCD3 T-cell-engaging bispecific antibody clinical development program, which aims to provide tailored treatment options that suit the diverse needs, preferences, and experiences of people with blood cancers and healthcare systems. Genentech is investigating Columvi as a monotherapy and in combination with other medicines for the treatment of diffuse large B-cell lymphoma (DLBCL) and mantle cell lymphoma.  

As part of Genentech’s efforts to elevate treatment standards in the earlier stages of DLBCL, where there is the best opportunity to improve long-term outcomes and prevent relapse, Columvi is also being investigated in combination with other medicines in previously untreated DLBCL in the Phase III SKYGLO study [GO44145; NCT06047080]. 

About diffuse large B-cell lymphoma (DLBCL) 

Diffuse large B-cell lymphoma (DLBCL) is an aggressive (fast-growing) blood cancer and is the most common form of non-Hodgkin’s lymphoma in the U.S. Approximately 160,000 people worldwide are diagnosed with DLBCL each year, with comparable incidence rates across regions. Medical practices, including pathological classification, diagnosis, staging, initial treatment and relapse management, are similarly approached worldwide. While it is generally responsive to treatment in the frontline, as many as 40% of people will relapse or have refractory disease, at which time salvage therapy options are limited and survival is short. Improving treatments earlier in the course of the disease and providing much-needed alternative options could help to improve long-term outcomes.

Columvi U.S. Indication

Columvi (glofitamab-gxbm) is a prescription medicine to treat adults with certain types of diffuse large B-cell lymphoma (DLBCL) or large B-cell lymphoma (LBCL) that has come back (relapsed) or that did not respond to previous treatment (refractory), and who have received 2 or more prior treatments for their cancer.

It is not known if Columvi is safe and effective in children.

The conditional approval of Columvi is based on response rate and durability of response. There are ongoing studies to establish how well the drug works.

What is the most important information I should know about Columvi?

Columvi can cause Cytokine Release Syndrome (CRS), a serious side effect that is common during treatment with Columvi, and can also be serious and lead to death.

Call your healthcare provider or get emergency medical help right away if you develop any signs or symptoms of CRS, including:

fever of 100.4°F (38°C) or higher
chills or shaking
fast or irregular heartbeat
dizziness or light-headedness
trouble breathing
shortness of breath

Due to the risk of CRS, you will receive Columvi on a "step-up dosing schedule".

A single dose of a medicine called obinutuzumab will be given to you on the first day of your first treatment cycle (Day 1 of Cycle 1).
You will start the Columvi step-up dosing schedule a week after the obinutuzumab dose. The step-up dosing schedule is when you receive smaller "step-up" doses of Columvi on Day 8 and Day 15 of Cycle 1. This is to help reduce your risk of CRS. You should be hospitalized during your infusion and for 24 hours after receiving the first step-up dose on Day 8. You should be hospitalized during your infusion and for 24 hours after receiving the second step-up dose on Day 15 if you experienced CRS during the first step-up dose.
You will receive your first full dose of Columvi a week after the second step-up dose (this will be Day 1 of Cycle 2).
If your dose of Columvi is delayed for any reason, you may need to repeat the "step-up dosing schedule".
If you had more than mild CRS with your previous dose of Columvi, you should be hospitalized during and for 24 hours after receiving your next dose of Columvi.
Before each dose of Columvi, you will receive medicines to help reduce your risk of CRS and infusion-related reactions.
Your healthcare provider will monitor you for CRS during treatment with Columvi and may treat you in a hospital if you develop signs and symptoms of CRS. Your healthcare provider may temporarily stop or completely stop your treatment with Columvi if you have severe side effects.

Carry the Columvi Patient Wallet Card with you at all times and show it to all of your healthcare providers. The Columvi Patient Wallet Card lists the signs and symptoms of CRS you should get emergency medical help for right away.

About Polivy (polatuzumab vedotin-piiq)
Polivy is a first-in-class anti-CD79b antibody-drug conjugate (ADC). The CD79b protein is expressed in the majority of B cells, an immune cell impacted in some types of non-Hodgkin lymphoma (NHL), making it a promising target for the development of new therapies. Polivy binds to cancer cells such as those expressing CD79b and destroys these B cells through the delivery of an anti-cancer agent, which is thought to minimize the effects on normal cells. Polivy is being developed by Genentech using Pfizer ADC technology and is currently being investigated for the treatment of several types of NHL.

Polivy U.S. Indication

Polivy is a prescription medicine used with other medicines (a rituximab product, cyclophosphamide, doxorubicin, and prednisone) as a first treatment for adults who have moderate to high risk diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS) or high-grade B-cell lymphoma (HGBL).

Polivy is a prescription medicine used with other medicines, bendamustine and a rituximab product, to treat DLBCL in adults who have progressed after at least 2 prior therapies.

On July 18, 2025 SpringWorks Therapeutics, Inc., a healthcare company of Merck KGaA, Darmstadt, Germany, reported that the European Commission (EC) granted conditional marketing authorization for EZMEKLY (mirdametinib) for the treatment of symptomatic, inoperable plexiform neurofibromas (PN) in pediatric and adult patients with neurofibromatosis type 1 (NF1) aged 2 years and above (Press release, SpringWorks Therapeutics, JUL 18, 2025, View Source [SID1234654439]). EZMEKLY is the first and only therapy approved in the European Union (EU) for both adults and children with NF1-PN.

"Patients with NF1-PN often face physical and mental health challenges and impaired quality of life given the limited treatment options available for this lifelong and debilitating disease," said Ignacio Blanco, MD, PhD, Chairman of the National Reference Center for Adult Patients with Neurofibromatosis at Hospital Universitari Germans Trias i Pujol, Spain. "This approval represents an important advance, especially for adults who previously did not have an approved treatment. In clinical trials, EZMEKLY demonstrated an encouraging efficacy and safety profile in both adults and children, and importantly, is available in a tablet that dissolves easily in water for people who are unable to swallow a pill and could therefore not previously receive therapy."

"This European Commission approval is an important milestone for NF patients and caregivers, as it means more treatment options for patients with plexiform neurofibromas, including adults," said Annette Bakker, PhD, Chief Executive Officer of the Children’s Tumor Foundation (CTF) and Dariusz Adamczewski, MD, Director CTF Europe. "This is the kind of progress that happens when researchers, industry and organizations like ours work together with a shared focus on delivering new treatments for patients."

NF1 is a genetic disorder that affects approximately 3 in 10,000 people in the EU, or an estimated 135,000 people.1,2 Among patients with NF1, the lifetime risk of developing plexiform neurofibromas is approximately 30% to 50%. These tumors grow in an infiltrative pattern along the peripheral nerve sheath and can cause severe disfigurement, pain and functional impairment.3,4​ Plexiform neurofibromas can transform into malignant peripheral nerve sheath tumors, an aggressive and potentially fatal disease.5 Surgical removal can be challenging due to the infiltrative tumor growth pattern of plexiform neurofibromas along nerves, and up to approximately 85% of plexiform neurofibromas are considered not amenable to complete resection.6,7,8

"Bringing innovation to patients living with rare tumors around the world is a clear reflection of our focus on addressing significant unmet needs and transforming outcomes for patients and their families," said Jan Kirsten, Global Head of Rare Tumor Business. "With the European approval of EZMEKLY, the first therapy approved for both adults and children with NF1-PN, we are taking a major step toward improving care for this underserved community and are committed to making our medicine available to eligible NF1-PN patients across Europe as quickly as possible."

The EC approval of EZMEKLY is based on results from the ongoing, multi-center, open-label, single arm Phase 2b ReNeu trial, which enrolled 114 patients with NF1-PN age 2 years or older (58 adults and 56 pediatric patients). The study met the primary endpoint of confirmed objective response rate (ORR), as assessed by blinded independent central review, demonstrating an ORR of 41% (N= 24/58) in adults and 52% in children (N=29/56). The median best percentage change in target PN volume was -41% (range: -90 to 13%) in adults and -42% (range: -91 to 48%) in children. Among those with a confirmed response, 88% percent of adults and 90% of children had a response of at least 12 months duration, and 50% and 48%, respectively, had a response of at least 24 months duration. Both adults and children also experienced early and sustained significant improvements from baseline in pain and quality of life as assessed across multiple patient-reported outcome tools.9

EZMEKLY demonstrated a manageable safety and tolerability profile. The most common adverse reactions reported in adults receiving EZMEKLY were dermatitis acneiform (83%), diarrhea (55%), nausea (55%), blood creatine phosphokinase increased (47%), musculoskeletal pain (41%), vomiting (37%) and fatigue (36%). The most common adverse reactions occurring in children were blood creatine phosphokinase increased (59%), diarrhea (53%), dermatitis acneiform (43%), musculoskeletal pain (41%), abdominal pain (40%), vomiting (40%), and headache (36%).9

EZMEKLY is available in 1 and 2 mg capsules and in a 1 mg dispersible tablet, which dissolves easily in water.

About the ReNeu Trial

ReNeu (NCT03962543) is an ongoing, multi-center, open-label, single arm, Phase 2b trial evaluating the efficacy, safety and tolerability of mirdametinib in patients ≥2 years of age with an inoperable NF1-associated PN causing significant morbidity. The study enrolled 114 patients to receive mirdametinib at a dose of 2 mg/m2 twice daily (maximum dose of 4 mg twice daily) without regard to food. Mirdametinib was administered orally in a 3-week on, 1-week off dosing schedule as either a capsule or dispersible tablet. The primary endpoint is confirmed objective response rate (ORR) defined as the proportion of patients with a ≥20% reduction in target tumor volume on consecutive scans during the 24-cycle treatment phase, as measured by MRI and assessed by blinded independent central review. Secondary endpoints include safety and tolerability, duration of response, and changes in patient-reported outcomes from baseline to Cycle 13. The treatment phase of the trial is complete, and results were presented at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. Patients who completed the treatment phase were eligible to continue receiving treatment in the optional long-term follow-up portion of the study, which is ongoing.

About NF1-PN

Neurofibromatosis type 1 (NF1) is a rare genetic disorder that arises from mutations in the NF1 gene, which encodes for neurofibromin, a key suppressor of the MAPK pathway.10,11 NF1 is the most common form of neurofibromatosis, with an estimated global birth incidence of approximately 1 in 2,500 individuals.3,12 In the EU, NF1 affects approximately 3 in 10,000 people, or an estimated 135,000 people.1,2 The clinical course of NF1 is heterogeneous and manifests in a variety of symptoms across numerous organ systems, including abnormal pigmentation, skeletal deformities, tumor growth and neurological complications, such as cognitive impairment.13 Patients with NF1 have an 8 to 15-year mean reduction in their life expectancy compared to the general population.1

Patients with NF have approximately a 30% to 50% lifetime risk of developing plexiform neurofibromas, or PN, which are tumors that grow in an infiltrative pattern along the peripheral nerve sheath and that can cause severe disfigurement, pain and functional impairment; in rare cases, NF1-PN may be fatal.3,4,5 NF1-PNs are most often diagnosed in the first two decades of life.3 These tumors can be aggressive and are associated with clinically significant morbidities; typically, they grow more rapidly during childhood.14,15

Surgical removal of these tumors can be challenging due to the infiltrative tumor growth pattern along nerves and can lead to permanent nerve damage and disfigurement.5 Up to approximately 85% of plexiform neurofibromas are considered not amenable to complete resection.6,7,8

About GOMEKLI/ EZMEKLY (mirdametinib)

GOMEKLI (mirdametinib) is an oral, small molecule MEK inhibitor approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult and pediatric patients 2 years of age and older with neurofibromatosis type 1 (NF1) who have symptomatic plexiform neurofibromas (PN) not amenable to complete resection.

Mirdametinib is marketed under the brand name EZMEKLY in the European Union and is conditionally approved by the European Commission (EC) for the treatment of symptomatic, inoperable plexiform neurofibromas (PN) in pediatric and adult patients with neurofibromatosis type 1 (NF1) aged 2 years and above.

The FDA and the EC have granted Orphan Drug designation for mirdametinib for the treatment of NF1.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Ocular Toxicity: GOMEKLI can cause ocular toxicity including retinal vein occlusion (RVO), retinal pigment epithelium detachment (RPED), and blurred vision. In the adult pooled safety population, ocular toxicity occurred in 28% of patients treated with GOMEKLI: 21% were Grade 1, 5% were Grade 2 and 1.3% were Grade 3. RVO occurred in 2.7%, RPED occurred in 1.3%, and blurred vision occurred in 9% of adult patients. In the pediatric pooled safety population, ocular toxicity occurred in 19% of patients: 17% were Grade 1 and 1.7% were Grade 2. Conduct comprehensive ophthalmic assessments prior to initiating GOMEKLI, at regular intervals during treatment, and to evaluate any new or worsening visual changes such as blurred vision. Continue, withhold, reduce the dose, or permanently discontinue GOMEKLI as clinically indicated.

Left Ventricular Dysfunction: GOMEKLI can cause left ventricular dysfunction. GOMEKLI has not been studied in patients with a history of clinically significant cardiac disease or LVEF <55% prior to initiation of treatment. In the ReNeu study, decreased LVEF of 10 to <20% occurred in 16% of adult patients treated with GOMEKLI. Five patients (9%) required dose interruption, one patient (1.7%) required a dose reduction, and one patient required permanent discontinuation of GOMEKLI. The median time to first onset of decreased LVEF in adult patients was 70 days. Decreased LVEF of 10 to <20% occurred in 25%, and decreased LVEF of ≥20% occurred in 1.8% of pediatric patients treated with GOMEKLI. One patient (1.8%) required dose interruption of GOMEKLI. The median time to first onset of decreased LVEF in pediatric patients was 132 days. All patients with decreased LVEF were identified during routine echocardiography, and decreased LVEF resolved in 75% of patients. Before initiating GOMEKLI, assess ejection fraction (EF) by echocardiogram. Monitor EF every 3 months during the first year and then as clinically indicated. Withhold, reduce the dose, or permanently discontinue GOMEKLI based on severity of adverse reaction.

Dermatologic Adverse Reactions: GOMEKLI can cause dermatologic adverse reactions including rash. The most frequent rashes included dermatitis acneiform, rash, eczema, maculo-papular rash and pustular rash. In the pooled adult safety population, rash occurred in 92% of patients treated with GOMEKLI and required permanent discontinuation in 11% of adult patients. In the pooled pediatric safety population, rash occurred in 72% of patients treated with GOMEKLI and resulted in permanent discontinuation of GOMEKLI in 3.4% of patients. Initiate supportive care at first signs of dermatologic adverse reactions. Withhold, reduce the dose, or permanently discontinue GOMEKLI based on severity of adverse reaction.

Embryo-Fetal Toxicity: GOMEKLI can cause fetal harm when administered to a pregnant woman. Verify the pregnancy status of females of reproductive potential prior to the initiation of GOMEKLI. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Also advise patients to use effective contraception during treatment with GOMEKLI and for 6 weeks after the last dose (females) or 3 months after the last dose (males).

ADVERSE REACTIONS

The most common adverse reactions (>25%) in adult patients were rash (90%), diarrhea (59%), nausea (52%), musculoskeletal pain (41%), vomiting (38%), and fatigue (29%). Serious adverse reactions occurred in 17% of adult patients who received GOMEKLI. The most common Grade 3 or 4 laboratory abnormality (>2%) was increased creatine phosphokinase.
The most common adverse reactions (>25%) in pediatric patients were rash (73%), diarrhea (55%), musculoskeletal pain (41%), abdominal pain (39%), vomiting (39%), headache (34%), paronychia (32%), left ventricular dysfunction (27%), and nausea (27%). Serious adverse reactions occurred in 14% of pediatric patients who received GOMEKLI. The most common Grade 3 or 4 laboratory abnormalities (>2%) were decreased neutrophil count and increased creatine phosphokinase.

USE IN SPECIFIC POPULATIONS

Pregnancy & Lactation. Verify the pregnancy status of patients of reproductive potential prior to initiating GOMEKLI. Due to the potential for adverse reactions in a breastfed child, advise patients not to breastfeed during treatment with GOMEKLI and for 1 week after the last dose.
You are encouraged to report negative side effects of prescription drugs to the FDA. To report suspected adverse reactions, contact SpringWorks Therapeutics at 1-888-400-SWTX (1-888-400-7989) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
