Keytruda, as an adjuvant treatment, is approved for Stage IB, II, or IIIA NSCLC patients.

Merck has announced that the US Food and Drug Administration (FDA) approved Keytruda (pembrolizumab) as an adjuvant treatment after surgery and platinum-based chemotherapy. It is approved in patients with stage IB, II, or IIIA non-small cell lung cancer (NSCLC).


The FDA approval was based on the KEYNOTE-091 trial, in which Keytruda demonstrated improvement in disease-free survival versus placebo in NSCLC patients following surgical resection and platinum-based chemotherapy. This is the fifth indication in the NSCLC setting and the 34th overall indication in the US.

In the Phase 3 KEYNOTE-091 trial, investigator-assessed disease-free survival (DFS) is the primary endpoint. Keytruda reduced the risk of disease recurrence or death by 27% versus the placebo. The median DFS was 58.7 months in patients on Keytruda versus 34.9 months in patients on placebo.

Merck announced the safety profile in the KEYNOTE-091 trial is consistent with the existing one.

Tzield approved for delaying Stage 3 T1D in adults and pediatrics with Stage 2 T1D

Provention Bio announced that Tzield (teplizumab) was approved for delaying progression to Stage 3 type-1 diabetes (T1D) in adults and pediatrics of age eight years and older with Stage 2 type-1 diabetes (T1D). Tzield prevented the progression to stage 3 T1D by twenty-five months versus placebo.

Tzield is an anti-CD3-directed antibody for intravenous use and is the first immunomodulatory agent approved for preventing the progression of stage 2 diabetes.

The approval was based on a double-blind, placebo-controlled trial in patients with stage 2 type 1 diabetes. Tzield was administered via intravenous infusion for 14 days; the primary endpoint is the time from randomization to progression to stage 3 type 1 diabetes. After 51 months, 45% of patients on Tzield were diagnosed with stage 3 type 1 diabetes versus 72% of patients who received a placebo. There was a statistically significant difference between Tzield versus placebo.

The common adverse events are decreased levels of white blood cells, rash, and headache.

Patients who progress to stage 3 T1D require insulin for life, and stage 3 T1D might lead to diabetic ketoacidosis.

Imfinzi, Imjudo plus chemotherapy was approved for NSCLC in the US.

AstraZeneca announced that the US Food and Drug Administration approved Imfinzi (durvalumab), Imjudo (tremelimumab), plus chemotherapy combination for patients with Stave IV non-small cell lung cancer.

The approval was based on the POSEIDON Phase III trial; a global open-label study aimed to determine the efficacy of Imfinzi (durvalumab), Imjudo (tremelimumab), plus chemotherapy versus chemotherapy in the first-line setting in patients with metastatic non-small cell lung cancer.

Imfinzi plus five cycles of Imjudo plus four cycles of chemotherapy reduced the risk of death by 23% versus chemotherapy. 33% of patients on the Imfinzi combination were alive after two years versus 22% of patients on chemotherapy. The combination reduced the risk of disease progression by 28% versus chemotherapy. 25% of patients on combination were alive after three years versus 13.6% on chemotherapy.

In the US, lung cancer is the second most common cancer; it was estimated that nearly 236,000 patients would be diagnosed with it in 2022. Only 8% of patients are alive after five years of diagnosis because of the poor prognosis.

The US FDA approved Tecvayli for multiple myeloma.

Janssen Pharmaceuticals have announced that the U.S. Food and Drug Administration (FDA) approved Tecvayli (teclistamab) for adult patients with refractory multiple myeloma. The drug is approved for patients previously treated with four or more prior lines of therapy, including a proteasome inhibitor, immunomodulatory drug, and anti-CD38 monoclonal antibody.

Tecvayli received accelerated approval based on response rate, and complete approval will be received upon verification of efficacy with confirmatory trials.

The accelerated approval was based on the Phase 2 MajesTEC-1 clinical trial, which recruited 110 patients treated with a median of five lines of therapy. Nearly 78% of patients were previously treated with four lines of treatment. The overall response rate (ORR) was 61.8%, and 28.2% showed a complete response. The median time for response was 1.2 months. At six months, the duration of response was 90.6%, and 66.5% at nine months.

Tecvayli is a bispecific T-cell engager antibody available in the subcutaneous form.

Rinvoq approved for non-radiographic axial spondyloarthritis, sixth indication approval in the US.

Rinvoq (upadacitinib) was approved for adults with active non-radiographic axial spondyloarthritis (nr-axSpA). Rinvoq is the first and only JAK inhibitor approved for nr-axSpA.

The approval was based on the Phase 3 SELECT-AXIS 2 trial, in which 44.9% of patients on Rinvoq achieved ASAS40 compared to 22.3% of patients on placebo at week 14. The efficacy was observed as early as the second week of the initiation of treatment.

Rinvoq can cause some severe adverse events. It might lead to severe infection by reducing the body's ability to fight infection; some might be fatal because of infections by tuberculosis (TB), bacteria, fungi, or viruses. It increases the death risk in patients 50 years and older with one or more heart disease risk factors. Further, it can increase the risk of cancers, including lymphoma and skin cancer. Patients with at least one risk factor of heart disease have increased chances of heart attack, stroke, and death. It also increases the chances of blood clots in these patients. It might also cause tears in the stomach or intestines.

US FDA approved Boostrix during pregnancy for preventing whooping cough in infants.

The United States Food and Drug Administration (FDA) approved Boostrix (Tetanus Toxoid, Reduced Diphtheria Toxoid, and Acellular Pertussis Vaccine, Adsorbed) in pregnant women for preventing whooping cough (pertussis) in infants younger than two months. Boostrix has to administer in the third trimester of pregnancy.

Also read: Drug approvals in Japan


The approval was based on the observational case-control study, and FDA found the real-world evidence appropriate for the approval. Boostrix was 78% effective in preventing whopping cough when administered during the third trimester of pregnancy.

The safety of Boostrix in the third trimester of pregnancy was assessed based on a randomized, placebo-controlled study in the ex-US population. It was observed to be safe, and FDA stated that since the formulation is the same, it was believed to be safe in the US population as the formulation contains the same components, except the percentage of aluminum is higher in the non-US formulation. There were no vaccine-related adverse events during pregnancy or in infants.
